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