I have added MaskedEditExtender and MaskedEditValidator controls from the Ajax Toolkit for .NET Framework 4.0 to my textboxes to provide enhanced functionality. However, since I've done that I am getting the following error in Visual Studio when I visit the page containing these controls.
Microsoft JScript runtime error: '2.length' is null or not an object
This is the information from the script page that Visual Studio breaks in.
When I right-click on the tab in Visual Studio and choose "Copy Full Path" it gives this.
When I hover over the tab in Visual Studio it gives this (as much as I could see in the tooltip).
This is the piece of code from line 21 of the file above, where Visual Studio breaks.
