NodeClick Event is not firing ?

[Madhu Palakurthi]

Hi,

I have added treeview in my aspx page like this..

  <asp:TableCell CssClass="dfv">
   <telerik:RadTreeView ID="tvChkSearchResult" runat="server" OnNodeClick="tvChkSearchResult_NodeClick"
    AutoPostBack="True" Width="300px" Height="200px" CheckBoxes="True" TriStateCheckBoxes="true"
 CheckChildNodes="true">
  </telerik:RadTreeView>
</asp:TableCell>

and binding here ...

Dim siteData As New List(Of TreeViewCheckbox)()
            If dt IsNot Nothing AndAlso dt.Rows.Count > 0 Then
                siteData.Add(New TreeViewCheckbox(1, 0, "Select All"))

                Dim i As Integer = 0
                Do While (i < dt.Rows.Count)
                    Dim row As DataRow = dt.Rows(i)
                    Dim srColumn As String = row(searchedColumn)
                    i = (i + 1)
                    siteData.Add(New TreeViewCheckbox(i + 1, 1, srColumn))
                Loop
            End If

            If Not String.IsNullOrEmpty(EditValue) Then
                siteData.Add(New TreeViewCheckbox(1, 0, "Select All"))
                siteData.Add(New TreeViewCheckbox(2, 1, EditValue.Trim()))
            End If

            tvChkSearchResult.DataTextField = "Text"
            tvChkSearchResult.DataFieldID = "ID"
            tvChkSearchResult.DataFieldParentID = "ParentID"
            tvChkSearchResult.DataSource = siteData
            tvChkSearchResult.DataBind()

Now I would like to fill up values in to textboxes that is based on selection on treeview.

but these events are not firing..

Protected Sub tvChkSearchResult_NodeCheck(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadTreeNodeEventArgs) Handles tvChkSearchResult.NodeCheck
       If tvChkSearchResult.SelectedNode.Checked Then
           Dim s As String = ""
       End If
   End Sub

   Protected Sub tvChkSearchResult_NodeClick(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadTreeNodeEventArgs) Handles tvChkSearchResult.NodeClick
       If tvChkSearchResult.SelectedNode.Checked Then
           Dim s As String = ""
       End If
   End Sub

Please help me on how to fire events ?

Thanks in advance..

Hello,

Please find attached a project that demonstrates how you can keep tack of both server-side events NodeCheck and NodeClick execution. The label control indicates whether check or click event if fired.
Please keep in mind using Visual Basic you can attach an event handler either from markup code or from code behind using the syntax Handles.


Kind regards,
