How to refresh the RadGrid On Treeview Node Click.

[Munish]

Hi,
I have one data bound tree view. 
On three view click i Need to refresh my Grid..

On Treenode click event handler. I called the RadGrid's Rebind Method and it call the RadGrid1_NeedDataSource method where i again reset the Datasource of the grid according to selection in the treeview. But my grid is not updating the datasource..

Here is some code..

protected void RadGrid1_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
 {
     if (!String.IsNullOrEmpty(RadTreeViewContainers.SelectedValue))
         RadGrid1.DataSource = WorkBoard.Client.Task.GetTaskByContainerId(RadTreeViewContainers.SelectedValue);
     else
         RadGrid1.DataSource = WorkBoard.Client.Task.GetTaskByContainerId(TaskFolders[0].Id);
 }

Node click handler 

protected void RadTreeViewContainers_NodeClick(object sender, RadTreeNodeEventArgs e)
  {
       RadGrid1.Rebind();
  }

DataSource is perfect but Not refreshing the grid.. But when manually refresh the grid from refresh button in grid. work awesome..
Please help me its very urgent..
Thanks.

Hello,

If your grid was ajaxified then please add below code in to your page

<telerik:RadAjaxManager ID="" runat="server">
          <AjaxSettings>
              <telerik:AjaxSetting AjaxControlID="RadTreeViewContainers">
                  <UpdatedControls>
                      <telerik:AjaxUpdatedControl ControlID="Radgrid1" />
                  </UpdatedControls>
              </telerik:AjaxSetting>
          </AjaxSettings>
      </telerik:RadAjaxManager>

or

if you used Asp:UpdatePanel then also set both control in same contentPanel.
