Add the AjaxManager Programmatically


Product Progress® Telerik® UI for ASP.NET AJAX AjaxManager


How can I programmatically create an AjaxManager control?


To achieve the desired scenario, you need to create the AjaxManager in the Page_Init event on a later stage.

The following example demonstrates how to define the AjaxManager control.

protected void Page_Init(object sender, EventArgs e)
    RadAjaxManager manager = new RadAjaxManager();
    manager.ID = "RadAjaxManager1";
Protected Sub Page_Init(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Init
    Dim manager As New RadAjaxManager()
    manager.ID = "RadAjaxManager1"
End Sub

Now you need to access the RadAjaxManager instance by calling the GetCurrent() static method of the RadAjaxManager class. Note that if you are creating the ScriptManager dynamically as well, you have to add it to the Page.Form.Controls collection before the RadAjaxManager control.


protected void Page_Load(object sender, EventArgs e)
    RadAjaxManager manager = RadAjaxManager.GetCurrent(Page);

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
    Dim manager As RadAjaxManager = RadAjaxManager.GetCurrent(Page)
End Sub
<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
    <script type="text/javascript">
        function GetAjaxManager() {
            var manager = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>")
