How is the way to add radAjaxPanel programmatically?
I have a MasterPage . I need added in content.
I tried with this in Init event of page:

         RadAjaxPanel radajaxPanel = new RadAjaxPanel();
         radajaxPanel.ID="RadAjaxPanel3";
         radajaxPanel.ClientEvents.OnRequestStart = "conditionalPostback";

         containerUpload.Controls.Add(radajaxPanel);           


but didn't work
thanks!

Hello Julieta,

If you wan to add an AjaxPanel into some placeholder from the codebehind, then you can do the following:

protected void Page_Init(object sender, EventArgs e)
{
    RadAjaxPanel rap1 = new RadAjaxPanel();
    rap1.ID = "ajaxPanel1";
    Button btn1 = new Button();
    btn1.ID = "btn1";
    Label lbl1 = new Label();
    lbl1.ID = "lbl1";

    rap1.Controls.Add(btn1);
    rap1.Controls.Add(lbl1);

    PagePlaceHolder.Controls.Add(rap1);

    btn1.Click += new EventHandler(btn1_Click);

}
void btn1_Click(object sender, EventArgs e)
{
    Label labelInsidePanel = (PagePlaceHolder.FindControl("ajaxPanel1") as RadAjaxPanel).FindControl("lbl1") as Label;
    labelInsidePanel.Text = DateTime.Now.ToString();
}
