Description

How can I programmatically create an AjaxManager control?

Solution

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.

C#

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

VB

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

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.

Server-Side

C#

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

VB

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

JavaScript

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