The RadAjaxControl class exposes a set of server-side methods.

Static Methods

RadAjaxManager provides a static method you can use to get a reference to the RadAjaxManager instance on the current page from the code-behind:

RadAjaxManager ram = RadAjaxManager.GetCurrent(Page);
Dim ram as RadAjaxManager = RadAjaxManager.GetCurrent(Page)

Instance Methods

The AjaxManager and AjaxPanel both descend from the RadAjaxControl, which introduces the following methods:

  • Alert—Executes a JavaScript alert() on the client. Alert() takes a single string parameter for text that will be displayed in the alert.

          RadAjaxManager1.Alert("Please save your changes.");
          RadAjaxManager1.Alert("Please save your changes.")    
  • FocusControl—Places the 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.

  • GetAjaxEventReference—Produces client-side code that invokes the ajaxRequest() method.

      //... returns "$find("RadAjaxManager1").ajaxRequest("Button1");"
      '... returns "$find("RadAjaxManager1").ajaxRequest("Button1");"
  • RaisePostBackEvent—Triggers a server-side AjaxRequest event and allows you to pass a single string parameter to the event. AjaxRequest can also be triggered by the client-side ajaxRequest() function.

          protected void Button1_Click(object sender, EventArgs e)
      protected void RadAjaxManager1_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
      End Sub
      Protected Sub RadAjaxManager1_AjaxRequest(ByVal sender As Object, ByVal e As Telerik.Web.UI.AjaxRequestEventArgs) Handles RadAjaxManager1.AjaxRequest
          Label1.Text = e.Argument
      End Sub
  • Redirect—Navigates the browser to another web page. The method passes a single string parameter, which is the URL to navigate to.
