I have a treeview and I want certain nodes to be checked when the page loads and some not checked. I want to do this manually before I loop through a database so was wondering if there is any VB.NET code out there that would show me.
I was thinking something like this (using objects):
Dim Cat As List(Of Category)
Cat = Category.GetAllCategories
If Not Cat Is Nothing Then
Dim C As New RadTreeNode
Dim CatEach As Category
For Each CatEach In Cat
C.Text = CatEach.Category
C.Value = CStr(CatEach.catID)
If C.Text = "Antiques" Then
C.Checked = True
End If
RadTreeView1.Nodes.Add(C)
Next
End If
The treeview renders nicely but the "Antiques" checkbox remains unchecked. Any help here would be very much appreciated.

Nevermind..... tristatecheckboxes was set to true and that is a bad thing.... I guess that indeterminate state or selection makes it where c.node.checked will not happen.
