Hi all,

I tried to set the ajax colorpicker SelectedColor property in the code behind, and I'm getting the same error.

I tried to add this js code as recommended above:

Sys.Application.add_init(function() {
        // Store the color validation Regex in a "static" object off of
        // AjaxControlToolkit.ColorPickerBehavior.  If this _colorRegex object hasn't been
        // created yet, initialize it for the first time.
        if (!AjaxControlToolkit.ColorPickerBehavior._colorRegex) {
            AjaxControlToolkit.ColorPickerBehavior._colorRegex = new RegExp('^[A-Fa-f0-9]{6}$');
        }
    });

But now I'm getting the error "AjaxControlToolkit" is not defined.

Can anyone help?!
