This help article describes the methods of RadAjaxControl and show examples how to use them.

RadAjaxManager and RadAjaxPanel both descend from RadAjaxControl,which introduces the following methods:

  • Alert - This method executes a JavaScript alert() on the client.Alert() takes a single string parameter for text to be displayed in the alert.

RadAjaxPanel1.Alert("Please save your changes.");


RadAjaxPanel1.Alert("Please save your changes.")

  • FocusControl - This method places focus on a specified control. FocusControl() takes a single parameter that can be the ID of the control to focus on or an object reference to the control to focus on.

RadAjaxPanel1.FocusControl(Button1);


RadAjaxPanel1.FocusControl(Button1)

  • GetAjaxEventReference - This method produces client side code that invokes the ajaxRequest() method.

RadAjaxPanel1.GetAjaxEventReference(Button1.ClientID);
//... returns "$find("RadAjaxPanel1").ajaxRequest("Button1");"


RadAjaxPanel1.GetAjaxEventReference(Button1.ClientID)
'... returns "$find("RadAjaxPanel1").ajaxRequest("Button1");"

  • RaisePostBackEvent - This method triggers a server-sideAjaxRequest event and allows you to pass a single string parameter to the event. (Example1 ). AjaxRequest can also be triggered by the client-sideajaxRequest() function.


protected void Button1_Click(object sender, EventArgs e)
{    
    RadAjaxPanel1.RaisePostBackEvent(DateTime.Now.ToString());
}
protected void RadAjaxPanel1_AjaxRequest(object sender, Telerik.Web.UI.AjaxRequestEventArgs e)
{    
    Label1.Text = e.Argument;
}


Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
            RadAjaxPanel1.RaisePostBackEvent(DateTime.Now.ToString())
End Sub
Protected Sub RadAjaxPanel1_AjaxRequest(ByVal sender As Object, ByVal e As Telerik.Web.UI.AjaxRequestEventArgs) Handles RadAjaxPanel1.AjaxRequest
            Label1.Text = e.Argument
End Sub
