hi mody, this actually proved to be a lot trickier than I expected. Seems Datagrid is not "fully" WPF compliant - it does not have a dependency property for its selected items (the way, say a ListBox or ComboBox has). https://stackoverflow.com/questions/22868445/select-multiple-items-from-a-datagrid-in-an-mvvm-wpf-project gave some options for a solution. I went with this one: >>One way to to what you want is to register the SelectionChanged event of the DataGrid to update the property of your ViewModel, that stores the selected items.<< Sub-classing the Datagrid and adding a dependency property for the selected items is a more sophisticated way to go for sure, and is explained in the stackoverflow post, but using the "SelectionChanged" event on the datagrid is v straighforward and this, at least, should get u pointed in the right direction. I will get this added as a sample to community samples for a complete solution. It's too much code to paste here in its entirety.   <UserControl x:Class="DatagridMultiSelect.UI.DataGridDockpaneView" ....> .... <Grid> .... <DataGrid Grid.Row="1" HorizontalAlignment="Stretch" Height="Auto" ItemsSource="{Binding FeatureData}" VerticalAlignment="Top" x:Name="dataGrid" Style="{DynamicResource Esri_DataGrid}" HeadersVisibility="Column" AutoGenerateColumns="True" IsReadOnly="True" SelectionMode="Extended" SelectionUnit="FullRow" CanUserSortColumns="True" RowHeaderWidth="0" Margin="0,0,5,0"/>     Code behind of the view:   public partial class DataGridDockpaneView : UserControl { public DataGridDockpaneView() { InitializeComponent(); this.Loaded += DataGridDockpaneView_Loaded; } private void DataGridDockpaneView_Loaded(object sender, RoutedEventArgs e) { var dg_vm = this.DataContext as DataGridDockpaneViewModel; dg_vm.SetDataGrid(this.dataGrid); }     and in the dockpane view model:   internal class DataGridDockpaneViewModel : DockPane { private const string _dockPaneID = "DatagridMultiSelect_UI_DataGridDockpane"; private DataGrid _dataGrid = null; private static readonly object _lock = new object(); internal void SetDataGrid(DataGrid dataGrid) { _dataGrid = dataGrid;//wire up the datagrid //From:https://stackoverflow.com/questions/22868445/select-multiple-items-from-a-datagrid-in-an-mvvm-wpf-project _dataGrid.SelectionChanged += (o, e) => { var grid = o as DataGrid; var selected = grid.SelectedItems; lock (_lock) { //"MyRecord" is whatever your custom DataGrid //content items are... var sel_fd = selected.OfType<MyRecord>().ToList(); //TODO - use the selection from the grid... // } }; } ... //Elsewhere: internal class MyRecord { //your custom class }                 ...

hi marco, so it's a bug. custom parameter properties in a layer file shld work. the dev team has submitted an issue. if u want to, u can open a bug report with Tech Support and they can link the internal issue to the bug report allowing u to track progress. The only thing working, it seems, per the dev team, as currently is if custom parameters are added directly to the URL - for example:   { "type" : "CIMFeatureTable", "displayField" : "STATE_NAME", "editable" : true, "dataConnection" : { "type" : "CIMStandardDataConnection", "customParameters" : [ <----- this is ignored! bug { "type" : "CIMStringMap", "key" : "token", "value" : "QVoIg1fwLpgBMAiov2v6P1CYanOHEn27wFNfQI4IoJfB8SG3qfUmnhJZeSS05yyj" } ], This shld work (note the url) "workspaceConnectionString" : "URL=https://acme.server.com/arcgis/rest/services/Acme_Layers/MapServer;CUSTOMPARAMETERS=token=QVoIg1fwLpgBMAiov2v6P1CYanOHEn27wFNfQI4IoJfB8SG3qfUmnhJZeSS05yyj", "workspaceFactory" : "FeatureService", "dataset" : "5", "datasetType" : "esriDTFeatureClass" }, "studyAreaSpatialRel" : "esriSpatialRelUndefined", "searchOrder" : "esriSearchOrderSpatial" }     ...
