Control Spy with .NET 2.0 failure

I'm trying to initialize RadControlSpyForm in a .NET 2.0 application and it throws the following exception:

System.InvalidCastException: 'Unable to cast object of type 'System.Windows.Forms.SplitContainer' to type 'System.ComponentModel.ISupportInitialize'.

I did some research, and I found that since SplitContainer doesn't inherit from System.ComponentModel.ISupportInitialize until .NET 4.0, this message shows up in solutions where a project is downgraded from .NET 4.0, but the Form designer isn't regenerated to remove the SplitContainer cast to ISupportInitialize to call BeginInit() and EndInit().

Hello, Sunny,

Indeed, our RadControlSpyForm internally uses the MS SplitContainer which throws the described exception when the application is run under .NET Framework 2.0. I confirm that it is an issue with the spy tool.

I have approved the item and you can track its progress, subscribe for status changes and add your comments on the following link - feedback item.

I have also updated your Telerik points.
