Please help me with this exception. I can't figure it out, I believe I am doing something wrong
with Infragistics grid. Thanks!

Hi,
From what you posted here, this exception doesn't seem to have anything to do with Infragistics. Infragistics assemblies are not mentioned anywhere in this call stack as far as I can see.
The exception appears to be occurring when the form is closed and a TextBox is getting disposed.
