Re: Treeview_ItemPopulate sub not firing

I have added a C1WebTreeView Control to a .ASCX contol. I'm able to add some itmes in the load event just fine. The problem I'm having is that I would like the tree to create itself dynamically when I click on the main items. So I've put code in the ItemPopulate sub as soon in the examples but it never gets fired. What would casue this?

Code:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Not IsPostBack Then

If Session("ResourceItem") IsNot Nothing Then

Session("CurrentPath") = Path.GetDirectoryName(CType(Session("ResourceItem"), ResourceItem).FullName)

Session("ResourceItem") = Nothing

End If

Dim thePath As String

thePath = Session("CurrentPath")

If String.IsNullOrEmpty(thePath) Then

thePath = Me._RootPath

Else

If Not thePath.EndsWith("\") Then thePath += "\"

If Not Me._RootPath.EndsWith("\") Then Me._RootPath += "\"

End If

LoadResources(thePath)

End If

End Sub

 

Private Sub LoadResources(ByVal thePath As String, Optional ByVal ItemToLoad As C1.Web.Command.C1WebTreeViewItem = Nothing)

Dim itm As C1.Web.Command.C1WebTreeViewItem

Dim rc As New ResourceCollection

rc.UserInfo = Me._UserInfo

rc.ReadPath(thePath)

For Each ri As ResourceItem In rc

itm = New C1.Web.Command.C1WebTreeViewItem

itm.PopulateOnDemand = True

itm.Text = ri.DisplayName

itm.CommandArgument = ri.FullName

If IsNothing(ItemToLoad) Then

Me.C1WebTreeView1.Items.Add(itm)

Else

If IsNothing(ItemToLoad.ChildGroup) Then ItemToLoad.CreateChildGroup()

ItemToLoad.ChildGroup.Items.Add(itm)

End If

Next

End Sub

 

Protected Sub C1WebTreeView1_ItemPopulate(ByVal sender As Object, ByVal e As C1.Web.Command.C1WebCommandEventArgs) Handles C1WebTreeView1.ItemPopulate

LoadResources(e.CommandArgument, e.Item)

End Sub

 

Hi,

Please use the following code:

Protected Sub C1WebTreeView1_ItemPopulate(ByVal sender As Object, ByVal e As
C1.Web.Command.C1WebCommandEventArgs) Handles C1WebTreeView1.ItemPopulate
LoadResources(path, e.Item)
End Sub

Instead of

Protected Sub C1WebTreeView1_ItemPopulate(ByVal sender As Object, ByVal e As
C1.Web.Command.C1WebCommandEventArgs) Handles C1WebTreeView1.ItemPopulate
LoadResources(e.CommandArgument, e.Item)
End Sub

Hope this helps.

Regards,
Patrick
