TreeView CheckBox Problem

[=?Utf-8?B?SG9seXNtb2tl?=]

Hi All,

I am trying to visualizze checkbox in my TreeView Control, but I does n't
show up. I see there is a space for checkbox but I don't see the checkbox.

I wonder what would have gone wrong

I set ShowAllCheckBox es = All, I generate the checkbox for the node which I
want via code.

Here is excerpt of my code,

<asp:TreeView ID="TvServer" Width="250" ExpandDepth="1"
runat="server" ShowCheckBoxes= "All" SkinID="Cubes">
</asp:TreeView>
Then on code behind i generate

TvServer.Nodes. Clear()
'Add TopNode
Dim TopNode As New TreeNode(My.App lication.Cache. ServerName,
My.Application. Cache.ServerNam e)
TopNode.Populat eOnDemand = False
TopNode.ShowChe ckBox = False
TvServer.Nodes. Add(TopNode)

For Each Cube As Cube In My.Application. Cache.Cubes
AddNode(Cube)
Next

But I does n't show up. Please Advice.

TIA,
Holy
