If you're receiving script errors, or alerts indicating that a *.js file cannot be loaded, the problem may be related to the .Visible property in the asp.net spell checker control or a container control. Having .Visible set false at some point in the ASP.NET page lifecycle, and then changing it to true later on (even in the same method) can cause the "PreRender" cycle of the child controls to be skipped. To avoid this problem, don't set .Visible to false if there's a possibility it will be set true later on. |
