Exception when grouping columns
posted

Hi.

That's what I do:

1. Enable row numeration in grid settings

2. Group rows by dragging some column to group panel

3. Open any group

3. Click row number on the any row

And that's what I get:

An unhandled exception ('Unhandled Error in Silverlight Application')

Code: 4004

Category: ManagedRuntimeError

Message: Infragistics.Silverlight.InvalideActiveCellException: The ActiveCell cannot belong to a column that has it's visibility set to Collapsed

And VS opens a dialog which asks me if I want to debug this app or not. So probably problem is not in my code.

    Hi, 

    So i tested this out, its definitely a bug.  Which has been fixed and will be in the next SR.  When you click on the RowSelector, it tries to set the cell in the first column of a row as Active. If that column is hidden however, you get the exception. 

    As a workaround, you can move your hidden columns to the end of the columns collection, and the exception will go away.
