RadAjax for ASP.NET AJAX

There are some cases where you might need to create the RadAjaxManager control programmatically. This is an easy task, however note this should be done in the Page_Init event but later. Below is a sample code you can use:

• C#
• VB.NET

CopyC#

protected void Page_Init(object sender, EventArgs e)
{
    RadAjaxManager manager = new RadAjaxManager();
    manager.ID = "RadAjaxManager1";
    this.Page.Form.Controls.Add(manager);
}

CopyVB.NET

Protected Sub Page_Init(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Init
    Dim manager As New RadAjaxManager()
    manager.ID = "RadAjaxManager1"
    Me.Page.Form.Controls.Add(manager)
End Sub

Then, to access the RadAjaxManager instance you can call the GetCurrent() static method of the RadAjaxManager class:

Server-Side

• C#
• VB.NET

CopyC#

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

CopyVB.NET

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
    Dim manager As RadAjaxManager = RadAjaxManager.GetCurrent(Page)
End Sub

CopyJavaScript

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
    <script type="text/javascript">
        function GetAjaxManager() {
            var manager = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>")
        }
    </script>
</telerik:RadCodeBlock>

Additionally, note that if you are creating the ScriptManager dynamically as well, you should add it to the Page.Form.Controls collection before the RadAjaxManager control.
