@MichaelVolz I have not used services in any of my workflows and am retiring next week, so you will have to do the experimentation on that yourself. ... View more

@MichaelVolz I have not done a lot of experimentation to determine the best available options for overcoming this problem under the current ArcGIS Pro limitations.  I can say none of the options appear to be worth the effort unless the tool is transferring the shape of the source feature to the target or the number of attributes being transferred is very large and difficult to transfer using standard manual value copy and paste operations between attribute tables.  I have found that the tool respects layer definition queries, so if a query can be written to ensure that the desired source or destination feature is available to be clicked and all other overlapping features are filtered out is a possible solution if the user is careful not to click the boundary of multiple features.  This assumes the user anticipates that overlapping features would otherwise occur and can figure out a query that ensures only a single desired featured is clicked.  The tool won't alert the user if they actually still had overlapping features exposed to the tool in their layer, so it is wise to first verify that only the desired features are clicked using the Explore tool first before doing any transfers. Some suggested definition queries that may be useful for restricting the available source or destination features include setting the area or length of the features to be less than or greater than a certain size or setting the ObjectID to be above a certain value.  Other query options would be specific to the data the user is working with.  For example, in some cases setting the available features to be above a certain date in a date field or greater that a certian alphabetical value in a text field could work.  The user still has the responsibility to verify that only the desired source or destination layers are selectable and only the desired destination layer is editable before doing the transfer and should avoid having more than one tranfer set up configured at a time. If I discover any other options, I will post them here, since even if Esri adds equivalency to a future release of ArcGIS Pro they won't implement it in any of the other releases for users that are not ready to update their release. ...

I also should mention that if multiple Attribute Transfer mappings have been set up that the number of dialogs that can appear for both the source and destination features can increase if the user cancels these dialogs to bring up another transfer mapped feature set.  Pressing the escape key can also cycle through the available source features when a single source feature is clicked and the dialog doesn't appear, but this is not true when a single feature is clicked in the first available target layer. This behavior can also occur when a feature class in the transfer mapping set up is used for multiple layers containing different definition queries which can lead to multiple dialogs appearing if the user cancels any of the dialogs and features in any of the other layers were clicked.  The dialogs appear in the Table of Contents order of the available sources or destinations beginning with the top most layer and continuing to the lowest layer clicked that is used by the transfer set ups.  It may be difficult to replicate this behavior in a single dockable window, which is typically the favored approach for tools in Pro as opposed to using multiple dialogs, which is the favored approach in ArcMap desktop.  However, in order for true equivalency to be achieved, these behaviors are additional requirements that the ArcGIS Pro version of the Attribute Transfer tool needs to provide. Obviously as the complexity of the transfer set up configurations increase, the user must assume greater responsibility to understand the tools possible behaviors and spend more time controlling the selectable layer and editable layer settings to manage their edits, but without the behavior I described in my original post, the tool becomes next to impossible to use when multiple features are clicked in a single layer in ArcGIS Pro even with the absolutely simplest transfer set up configuration in place. ...

The overall file geodatabase is still compatible with ArcCatalog/ArcGIS Desktop, but the individual feature classes and datasets within it can be rendered incompatable with the enhanced features listed by Ayan.  While all editing has to be performed in ArcGIS Pro to take advantage of the enhanced capabilities as intended by the data designer, it is still possible to create a simple feature class in that file geodatabase or in SDE that duplicates the schema without the enhanced capabilities and use the Truncate and Append tools in ArcGIS Pro to create a feature class that can be opened in ArcCatalog/ArcMap for a version of the feature class used for viewing publication only purposes.  Of course it then has to undergo scheduled updates to periodically be synchronized with the edit version thereafter and cannot otherwise remain current with the edit version. ...

I have a question about using transparency on the text element.  Can you tell me where the text element transparency is exposed through the ArcGIS Pro interface?  I am unable to find where the transparency property of the text element is set.  It does not appear on any ribbon when I select the element that is set to 100% transparent, nor does a transparency property appear within the Text Symbol properties of the text element on the Element tab when I select a text element.  I am asking, because I need to manually change the set up the template layout to make all items visible with black text color, but I wanted to also be able to manually set the transparency of the items that I wanted to be opaque or transparent for a specific layout.   I prefer to not set the Visible property of the elements to false, since then they cannot be selected on the layout itself.  They can only be accessed through the Contents pane for the layout if the Visible property is set to false.  The Transparency property allows me to select the elements on the layout, but I don't see where to set it manually. ...

Based on the code you provided I have created the following method that finds the text element by the name that is passed to the method and sets the transparency to the value that is passed:   public async static void SetTextTransparency(string ElementName, int TextTransparency) { // Ensure TextTransparency is within transparency bounds if (TextTransparency < 0) TextTransparency = 0; if (TextTransparency > 100) TextTransparency = 100; var myLayoutView = LayoutView.Active; if (myLayoutView == null) return; await ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() => { //Reference and load the layout associated with the layout item Layout lyt = myLayoutView.Layout; if (lyt == null) return; //Reference a text element by name TextElement txtElm = lyt.FindElement(ElementName) as TextElement; if (txtElm == null) return; //Change TextProperties var cimSym = txtElm.GetDefinition(); cimSym.Visible = true; var cimTextGraphicBase = (cimSym as CIMGraphicElement).Graphic; if (cimTextGraphicBase == null) return; cimTextGraphicBase.Transparency = TextTransparency; txtElm.SetDefinition(cimSym); }); }    I have also rewritten my method for setting the text value to follow a similar coding pattern to make sure  that the process of checking for null values is more thorough. ...

On September 28, 2022, I released a new version of  my Add-In that added an option to search for Township Range and Section(s) within Riverside County.  This is how the tool looks:   If you only want to find a single Section you can use the keyboard to do all the steps. Type the number of the Township you want (Example 2) and press the Tab key Type the number of the Range you want (Example 6) and press the Tab key. Optionally you can toggle the slider button to change the W and E Direction of the Range by pressing the Enter or Space key and press the Tab key The grid will change at each of the above steps and if any Sections do not fall within Riverside County they will be disabled. Type the number of the Section you want (Example 28) and press the tab key - the number you typed will blank out and the appropriate Section toggle button within the central Township and Range of the grid will be selected (if it is valid in Riverside County). The Launch button will now have focus and you can press the Enter key or Space key on your keyboard to activate the Launch button and zoom to the Section.    If you only want to use the mouse you can Left Click on the Township and Range combobox dropdowns and the Slider Button for W and E to chose the Township and Range you want. To select one or more Sections in the grid with the mouse there are several options: You can do a single Left Click on one of the Section toggle buttons to select it and deselect all other selected toggle buttons.  If you do a single Left Click while holding the Shift Key on the Keyboard you can select additional Section toggle buttons individually without affecting any selected toggle buttons that you didn't click.  If you do a single Left Click while holding the Control Key on the Keyboard you can invert the selection of each Section toggle button individually (if it is unselected, it becomes selected or if it is selected, it becomes unselected).  This does not affect any selected toggle buttons you didn't click.  You can Left Click, Drag and Release the Left mouse button to select a rectangular group of Section toggle buttons and deselect any selected toggle buttons that are outside of the rectangle.  When dragging in the mode the rectangle appears like this:   You can Left Click, Drag and Release the Left mouse button while holding the Shift Key on the Keyboard to select all of the Section toggle buttons that fall within the rectangle you drew.  The Section toggle buttons that were selected that are outside of the rectangle will be unaffected.   When dragging in this mode the rectangle appears like this:       You can Left Click, Drag and Release the Left mouse button while holding the Control Key on the Keyboard to invert the selection of Section toggle buttons within the rectangle you drew.  The Section toggle buttons that were selected that are outside of the rectangle will be unaffected.   When dragging in this mode the rectangle appears like this:     ...

@ChrisFoxI had never tried the SQL syntax you outlined, but this expression does work in ArcMap and ArcGIS Pro for related data in the same geodatabase.  This syntax is only briefly discussed in the Subqueries section of the SQL reference for query expressions used in ArcGIS website.  That section doesn't include an example that was quite as clear or useful to me as the one you have given.  I frankly would like to see your example added to that section, since if it had been there years ago I would have been much more likely to see the usefulness of this approach and not had to develop some of the workarounds I came up with. Your example works for file geodatabases as well, despite the warning that file geodatabases only offer limited support for subqueries.  The Subqueries section basically says that help for using them is specific to the DBMS documentation of my enterprise geodatabase.  Since I've mostly worked with file geodatabases that limitation warning had kept me from even trying to figure out or use Subqueries, but based on the example you have outlined I believe I actually now have a use for them.  Thanks. ...

I also figured out how to implement a property that can set the IsSelected property of the ListBoxItems of a ListBox so that it supports a TwoWay update when the Selection Mode is set to Extended and it does not have to be passed as a CommandParameter to an ICommand button.  I found that the Extended SelectionMode only mostly worked properly when I included the ListBox parameter for VirtualizingStackPanel.IsVirtualizing="False" along with setting the SelectionMode="Extended".   It does not appear to trigger a notification when the user actually extends their multiselection in the ListBox, so as far as I can tell the  evaluation or programmatic use of the ListBox IsSelected property has to be triggered by Methods and Actions you design in your code. In this example code I am presenting a list of Lot numbers so I made my ItemSource binding to an ObservableCollection called Lots.  This ObservableCollection contains ListBoxItems based on a custom class called LotSelector.  I had to set up an ItemTemplate for the ListBox so the list would display the Item property of the LotSelector custom class in the ListBox and an ItemContainerStyle of ListBoxItems that would assign the IsSelected property of each ListBoxItem to the IsSelected property of my LotSelector custom class.  Here is the xaml for the ListBox:   <ListBox x:Name="lbxLots" VirtualizingStackPanel.IsVirtualizing="False" SelectionMode="Extended" ItemsSource="{Binding Lots, Mode=TwoWay}" SelectedItem="{Binding SelectedLot}"> <ListBox.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding Item}"></TextBlock> </DataTemplate> </ListBox.ItemTemplate> <ListBox.ItemContainerStyle> <Style TargetType="{x:Type ListBoxItem}"> <Setter Property="IsSelected" Value="{Binding Mode=TwoWay, Path=IsSelected}" /> </Style> </ListBox.ItemContainerStyle> </ListBox>   I then added a Class Item to my project named LotSelector and defined two classes in the file.  The first class is named LotSelector and stores the values and IsSelected state of each ListBoxItem.  The second class is named LotItemComparer based on the IComparer class so that the LotSelector instances could be sorted and kept unique using a SortedSet<LotSelector> ViewModel property.  Here is the LotSelector.cs file code:   using System; using System.Collections.Generic; using ArcGIS.Desktop.Framework.Contracts; namespace RivCoSearchForms { public class LotSelector : PropertyChangedBase { private string _item; public String Item { get { return _item; } set { _item = value; NotifyPropertyChanged(() => Item); } } private bool _isSelected; public bool IsSelected { get { return _isSelected; } set { _isSelected = value; NotifyPropertyChanged(() => IsSelected); } } } public class LotItemComparer : IComparer<LotSelector> { public int Compare(LotSelector x, LotSelector y) { // TODO: Handle x or y being null, or them not having Items return x.Item.CompareTo(y.Item); } } }   For the ViewModel I added standard code for my Lots ObservableCollection<LotSelector> property for the ListBox ItemSource and a SelectedLot string property for the SelectedItem property of the ListBox.  I also added a SortedSet<LotSelector> private property of the ViewModel to ensure the Lots were distinct and sorted and could be manipulated on the MTC thread.  I have included a Command implementation to show how the ListBox could be populated based on the Lot data in a Layer.  (I tried to simplify the code of the Command from a more complex version and have not tested it, so the Command code may not run correctly and need correction.)   Here is the ViewModel code:   private ObservableCollection<LotSelector> _lots = new ObservableCollection<LotSelector>(); public ObservableCollection<LotSelector> Lots { get { return _lots; } set { SetProperty(ref _lots, value, () => Lots); } } private string _selectedLot; public string SelectedLot { get { return _selectedLot; } set { SetProperty(ref _selectedLot, value, () => SelectedLot); // Blank out Book, Page list and text block Message = null; } } private SortedSet<LotSelector> ListLotsSelected; public ICommand CmdCancel => new RelayCommand((proWindow) => { // TODO: set dialog result and close the window (proWindow as ProWindow).DialogResult = false; (proWindow as ProWindow).Close(); }, () => true); public ICommand CmdListLotsInLayer => new RelayCommand(async (proWindow) => { ListLotsSelected = new SortedSet<LotSelector>(new LotItemComparer()); // Get the Active Mapview var ActMap = MapView.Active; // Get the search layer from its name var fLayer = ActMap.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>().FirstOrDefault(l => l.Name.Equals("Search Lot Layer")); // If layer exists proceed if (fLayer != null) { // Set up a Queued Task for map changes int iCount = await ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() => { // Execute a Search on the layer using (RowCursor RecMapCursor = fLayer.Search()) { int cnt = 0; // Iterate the found cursor rows while (RecMapCursor.MoveNext()) { // Get current row as a feature using (Feature feature = (Feature)RecMapCursor.Current) { // Get the APN value of the feature LotSelector Lot = new LotSelector(); int number; bool success = int.TryParse(feature[LotField].ToString(), out number); if (success) { Lot.Item = feature[LotField].ToString().PadLeft(4); } else { Lot.Item = feature[LotField].ToString(); } // Set the IsSelected property to select the ListBoxItem Lot.IsSelected = true; // Update the ListLotsSelected parameter ListLotsSelected.Add(Lot); cnt += 1; } } return cnt; } }); if (iCount > 0) { Lots.Clear(); foreach (LotSelector _Lot in ListLotsSelected) { Lots.Add(_Lot); } } } }, () => true);     ...
