[.NET] ArcCatalog 10.1 tree doesn't refresh after adding new custom IGxObject

IlyaSolovyev

I am using ArcObjects 10.1 (.NET) to customize ArcCatalog: adding new nodes in catalog tree like in the Esri's example. But when I add new child node to already expanded parent, it doesn't show up in tree. Actually, custom catalog tree node never updates again after being expanded.

Any solutions?

Ilya,

Here is some VBA code I have used that shows a "brute force" refresh of all folder connections in the Catalog Tree.

Public Sub refreshFolders()
    ' Get ArcCatalog Application
    Dim pApp As IGxApplication
    Set pApp = Application


    ' Get the Catalog
    Dim pGXCatalog As IGxCatalog
    Set pGXCatalog = pApp.Catalog


    ' QI Catalog into GXObject
    Dim pGXObject As IGxObject
    Set pGXObject = pGXCatalog


    ' QI GxObject into GxObjectContainer
    Dim pGxObjectContainer As IGxObjectContainer
    Set pGxObjectContainer = pGXObject


    ' Get Gxobjects as an enumerate
    Dim pEnumGxObject As IEnumGxObject
    Set pEnumGxObject = pGxObjectContainer.Children


    ' Cycle through objects until we find the Folder Connections, then break out of loop
    Dim pGxObject2 As IGxObject
    Set pGxObject2 = pEnumGxObject.Next
    Do While Not pGxObject2 Is Nothing
        If TypeOf pGxObject2 Is IGxFolderConnections Then
            Exit Do
        End If
        Set pGxObject2 = pEnumGxObject.Next
    Loop


    ' Re-point GxObjectContainer to folder connection GxObject and refresh all children GxObjects
    Set pGxObjectContainer = pGxObject2
    Set pEnumGxObject = pGxObjectContainer.Children
    Set pGxObject2 = pEnumGxObject.Next
    Do While Not pGxObject2 Is Nothing
        pGxObject2.Refresh
        Set pGxObject2 = pEnumGxObject.Next
    Loop
End Sub
