I'm brand new to ArcObjects SDKs and am struggling. I have a Python Add-in performing a query to select records (works great)and now trying to call the identify dialog via an .NET addin button that displays the identify dialog box to show attributes of the selected records. Below is the code I have at this point. I currently have the identify dialog displaying, but no records appearing. I know I need to input the selected records somewhere....but not sure where. Any thoughts would be appreciated. (I'm using Visual Studio/Microsoft Visual Basic 2010 and ArcGIS 10.2.1)

Imports ESRI.ArcGIS.ArcMapUI
Imports ESRI.ArcGIS.Carto

Public Class Identify_Button
Inherits ESRI.ArcGIS.Desktop.AddIns.Button
Dim pMxDoc As IMxDocument
Dim activeView As IMap

Public Sub DoIdentify(ByVal activeView As ESRI.ArcGIS.Carto.IActiveView, ByVal x AsSystem.Int32, ByVal y As System.Int32)
pMxDoc = My.ArcMap.Application.Document
activeView = pMxDoc.FocusMap
If activeView Is Nothing Then
    Return
End If

Dim map As ESRI.ArcGIS.Carto.IMap = activeView.FocusMap
Dim identifyDialog As ESRI.ArcGIS.CartoUI.IIdentifyDialog = New ESRI.ArcGIS.CartoUI.IdentifyDialogClass
identifyDialog.Map = map

'Clear the dialog on each mouse click
identifyDialog.ClearLayers()
Dim screenDisplay As ESRI.ArcGIS.Display.IScreenDisplay = activeView.ScreenDisplay

Dim display As ESRI.ArcGIS.Display.IDisplay = screenDisplay ' Implicit Cast
identifyDialog.Display = display

Dim identifyDialogProps As ESRI.ArcGIS.CartoUI.IIdentifyDialogProps = CType(identifyDialog, ESRI.ArcGIS.CartoUI.IIdentifyDialogProps) ' Explicit Cast
Dim enumLayer As ESRI.ArcGIS.Carto.IEnumLayer = identifyDialogProps.Layers
enumLayer.Reset()

Dim layer As ESRI.ArcGIS.Carto.ILayer = enumLayer.Next

Do While Not (layer Is Nothing)
    identifyDialog.AddLayerIdentifyPoint(layer, x, y)
    layer = enumLayer.Next()
Loop

identifyDialog.Show()

End Sub
Public Sub New()

End Sub

Protected Overrides Sub OnClick()
    DoIdentify(activeView, 300, 100)
End Sub

Protected Overrides Sub OnUpdate()
    Enabled = My.ArcMap.Application IsNot Nothing
End Sub
  • Not sure how the python/.net interfaces. Are you saying that you want the selected features to be selected in ArcMap? Getting features to select in the ArcMap environment isn't as straightforward as it appears, to work with selecting features you need to look at IFeatureSelection help.arcgis.com/en/sdk/10.0/arcobjects_net/componenthelp/… which works with IFeatureLayer. Ensure you use ILayer.Valid and TypeOf() is IFeatureLayer to avoid potential problems. – Michael Stimson Apr 22 '14 at 1:47

This was a struggle, and I'm sure there is a classier way, but this is the code that I finally got working. The only glitch is that the identify box expands the first layer (so you can see all selected records), but the second layer stays condensed. You have to manually click the "+" to expand after the script runs. Any thoughts on that?
