Force a Postback with the AjaxManager or AjaxPanel

Environment

Description

How can I force a postback with the Telerik UI for ASP.NET AjaxManager or AjaxPanel?

Solution

To perform a single postback instead of an AJAX request, set arguments.EnableAjax to false.

The following example demonstrates the code-behind.

if (!RadAjaxManager1.EnableAJAX)
    {
         RadAjaxManager1.ClientEvents.OnRequestStart = "OnRequestStart";
    }

 If Not RadAjaxManager1.EnableAJAX Then
        RadAjaxManager1.ClientEvents.OnRequestStart = "OnRequestStart"
End If

The following example demonstrates the settings on the client.

function OnRequestStart(sender, args) {
    args.set_enableAjax(false); 
}

To disable AJAX because of unsupported browsers or previous browser versions, it is recommended that you do it on the server as demonstrated in the following snippets.

RadAjaxManager1.EnableAJAX = Page.Request.Browser.SupportsXmlHttp;

RadAjaxManager1.EnableAJAX = Page.Request.Browser.SupportsXmlHttp
