The TargetControlID of 'CalendarExtender1' is not valid. A control with ID 'text1' could not be found

I have created the Textbox and using CalendarExtener dynamically. I am getting the error"The TargetControlID of 'CalendarExtender1' is not valid. A control with ID 'text1' could not be found."

The below is my code

protected void Page_Load(object sender, EventArgs e)
    {
        TextBox tb = new TextBox();
        tb.ID = "text1";
        AjaxControlToolkit.CalendarExtender publishdate = new AjaxControlToolkit.CalendarExtender();
        publishdate.ID = "CalendarExtender1";
        publishdate.TargetControlID = tb.ID;
        Panel1.Controls.Add(publishdate);
    }

You haven't added the TextBox to the page's control collection.

Panel1.Controls.Add(tb);
Panel1.Controls.Add(publishdate);

Can i ask why you want to create it dynamically? That will make things much more difficult than adding declaratively and might cause issues with events or ViewState.
