In VS.2005 Using VB.NET on a windows XP (sp2) fully patched.
I have a project that has a Microsoft DataGridView on it.
Occasionally, when I click on a column header, I get:
ArgumentExceptionIsUnHandled
At least one object must implement IComparable
this problem is Intermittent, it doesn't happen all the time,
but happens about once in every five clicks of the column header.
I am at a total loss as to what this could be.
Thanks in Advance,
Laurence
Here is the detail:
System.ArgumentException was unhandled
Message="At least one object must implement IComparable."
Source="mscorlib"
