IQueryName2.CopyLocally Property will copy your table into the scratch workspace in your system temp directory to assign ObjectID column to your result table. The ObjectID column is used for selections. For more information check IQueryName2 Interface documentation. ... View more

My first thought is to handle the visibility of the item according to its file type. you can bind the visibility of the Item Template to the uri with converter to set visibility to Visible if it matched your filter. It's a quick solution and if you have more complex business you should implement your own control. Check this post for something similar. Regards, ... View more

Hi Carsten, you can't apply spatial filter on IQueryDef so your approach to use TableQueryNameClass is a good idea if your tables are in the same geodatabase, use it with query definition and then use a spatial filter. http://resources.arcgis.com/en/help/arcobjects-net/conceptualhelp/index.html#/d/000100000146000000.htm ...

Hello David, I have implemented a method which will loop over a folder contents (selected folder or specific folder name) and close all active database connections inside it.     private void DisconnectActiveSDEConnections(IGxApplication gxApp, bool useSelectedFolder = false, string folderName = "Database Connections")         {             IGxCatalog gxCatalog = gxApp.Catalog;             object connectionsFolder = null;             IGxSelection gxSel = null;             IGxObject gxObj = null;             int numFound;             try             {                 if (useSelectedFolder)                 {                     gxSel = gxApp.Selection;                     gxObj = gxSel.Location;                 }                 else                 {                     connectionsFolder = gxCatalog.GetObjectFromFullName(folderName, out numFound);                     if (numFound != 1 || connectionsFolder == null)                     {                         MessageBox.Show("Folder not found!");                         return;                     }                     gxObj = connectionsFolder as IGxObject;                 }                 if (gxObj is IGxObjectContainer)                 {                     IGxObjectContainer gxObjCont = null;                     IEnumGxObject gxEnum = null;                     IGxObject gxObject = null;                     IGxDatabase2 gxDatabase = null;                     gxObjCont = gxObj as IGxObjectContainer;                     gxEnum = gxObjCont.Children; //enumerate folder contents                     gxObject = gxEnum.Next();                     while (gxObject != null)                     {                         gxDatabase = gxObject as IGxDatabase2;                         Debug.Print(gxObject.Category);                         if (gxDatabase != null && gxDatabase.IsConnected)                         {                             gxDatabase.Disconnect();                               Debug.Print(gxObject.FullName + " Disconnected");                         }                         gxObject = gxEnum.Next();                     }                 }             }             catch (Exception ex)             {                 MessageBox.Show(ex.ToString());             }         } Regards, Ahmed ...

You can start with template theme of Magnifier sample, It's a rounded map. I tried it with silverlight and it should work with WPF too. Regards, ... View more

As Mody said you can pass your template layer as string because it's a Multi value parameter. You can also use ESRI.ArcGIS.DataManagementTools.CreateFeatureclass which is the same. Another approach is to use IfeatureWorkspace.CreateFeatureClass and pass your fields from Template featureclass. Regards, ... View more

The dependency property works with any silverlight sample.  I'm still confuse? It depends on what you want, but basically if you want to pass object from your MainPage -which hosts your controls- to your child controls, you can use dependency property as you can bind to it. ... View more

Hi all I've used sample "Bind a geodatabase table to .net control" to show attribute table of feature layers in a datagridview. Now, i wanna update that datagridview when user selects some features in map and select corresponding rows. Is there any code or sample for that? I've searched all internet but no help. Regards I have implemented a function based on ""Bind a geodatabase table to .net control"" sample, use this function when selection changed (may be in ActiveView Selection Changed). You should pass your featurelayer and ObjectID field as parameters. you should modify the code/parameters according to your business. private void UpdateGridSelection(IFeatureLayer featureLayer,string oIDField) {     try     {         //Clear Selection         dataGridView1.ClearSelection();         //Get Selection set and populate Object IDs in List         IFeatureSelection pFeatureSelection = featureLayer as IFeatureSelection;         ISelectionSet pSelectionSet = pFeatureSelection.SelectionSet;         IEnumIDs IDsEnum = pSelectionSet.IDs;         int Id = -1;         Id = IDsEnum.Next();         List<int> IdList = new List<int>();         while (Id != -1)         {             IdList.Add(Id);             Id = IDsEnum.Next();         }         //Select Rows Matches Selected Features By Its Object ID         if (IdList.Count > 0)         {             var rows = from row in dataGridView1.Rows.Cast<DataGridViewRow>()                        where IdList.Contains(Convert.ToInt32(row.Cells[oIDField].Value))                        select row;             foreach (var item in rows)             {                 item.Selected = true;             }         }     }     catch (Exception ex)     {         MessageBox.Show(ex.ToString());     } } Regards, Ahmed ...

Hi, I am trying get layer names to text  box but i am not getting result.Here is my code Can any one help IMxDocument imx = m_application.Document as IMxDocument;                      IMap map = imx.FocusMap;             StreamWriter sw = new StreamWriter("C:\\temp\\layer.txt"); //Use StreamWriter inside Using statement             ILayer layer =null;            // int lcount = map.LayerCount;             IEnumLayer player = map.get_Layers(null, false);             for (int i=0;i<map.LayerCount;i++) //Don't loop here            layer = player.Next();             //You should check layer object not player             while (player!=null)                        {                 sw.WriteLine(layer.Name);                 layer = player.Next();             }                     } Try this, I have also explained what's wrong with your code:             IMxDocument imx = ArcMap.Application.Document as IMxDocument;             IMap map = imx.FocusMap;             ILayer layer = null;             //Get Layers             IEnumLayer player = map.get_Layers(null, false);             layer = player.Next();             //Write Layers To Stream             using (StreamWriter writer = new StreamWriter("C:\\temp\\layer.txt", true))             {                 while (layer != null)                 {                     writer.WriteLine(layer.Name);                     layer = player.Next();                 }             } Regards, ...

Hello Ahmed, your sample works nice as described, but removing templates permanently is not what I intended. Any idea about just temporarily filtering those templates? Thanks and Regards Fossi I didn't find a way to access filter window yet. It's included in the create feature dockable window and I don't think that you can access it. Check this sample for a custom feature template box,It may help you. http://blogs.esri.com/esri/arcgis/2011/12/13/implementing-a-feature-template-dialog-box-in-your-code/ ... View more

What about Frequency Tool,It will get the count. You can get the result in InMemory Table and populate it to your list. You can run the tool from Arcmap and check its performance and output structue. Sample:   private ITable RunFrequencyTool(ITable inputTable, string inputField)         {             try             {                 ESRI.ArcGIS.AnalysisTools.Frequency FrequencyTool = new ESRI.ArcGIS.AnalysisTools.Frequency();                 ESRI.ArcGIS.Geoprocessing.IGeoProcessorResult Result;                 FrequencyTool.in_table = inputTable;                 FrequencyTool.frequency_fields = inputField;                 FrequencyTool.out_table = "in_memory\\Result";                 Result = RunTool(FrequencyTool, null);                 return GetTablefromResult(Result);             }             catch (Exception ex)             {                 MessageBox.Show(ex.ToString());                 return null;             }         }   private ESRI.ArcGIS.Geodatabase.ITable  GetTablefromResult(ESRI.ArcGIS.Geoprocessing.IGeoProcessorResult result)         {             ESRI.ArcGIS.Geodatabase.IGPValue GPVal;             string OutputTableName;             ESRI.ArcGIS.Geoprocessing.IGPUtilities3 GPUtil = new ESRI.ArcGIS.Geoprocessing.GPUtilities() as ESRI.ArcGIS.Geoprocessing.IGPUtilities3;             ESRI.ArcGIS.Geodatabase.ITable  pOutputTable;             try             {                 GPVal = result.GetOutput(0);                 OutputTableName = GPVal.GetAsText();                 pOutputTable = GPUtil.OpenTableFromString(OutputTableName);                 return pOutputTable;             }             catch (Exception ex)             {                 return null;             }         } ...
