Solution 1

The control is a child of the panel, not the form. Use something like this:

C#

updatePanel1.checkBox1.Checked = true;

1]check in designer it has runat="server" property is assigned or not.
2]check in the designer .cs file find the control by it's name as checkbox1 it has to be there.
3]check is the page is successfully inherited from System.Web.UI.Page or not.
4]check is your control is asp.net control or not.
