fire needdatasource in update panel

[Łukasz Kuryło]

Hi all.
In radgrid, after some operation on client side I want to refresh the grid, so I use __doPostBack(gridid). Update panel is refreshing, but only Page_Load is fired, not needdatasource event. How can I refresh the update panel and refresh the data in grid?

Hello,

If you are using AjaxPanel, then you can invoke an ajaxRequest() from client side and call the Rebind() method from code behind in AjaxRequest server event.

client code:

function InitiateAjaxRequest(arguments)
{
  // your code
  var ajaxPanel = $find("<%= RadAjaxPanel1.ClientID %>");
  ajaxPanel.ajaxRequest(arguments);
}

code behind:

    protected void RadAjaxPanel1_AjaxRequest(object sender, Telerik.Web.UI.AjaxRequestEventArgs e)
    {
       // rebind the grid here
    }
