Exception when you hide, move, unhide columns
posted

We have discovered a bug in version 8.2 of the XamDataGrid.  If you perform the following steps with a databound XamDataGrid:

1. Hide a column

2. Move a different column

3. Unhide the column from step 1

You will get a KeyNotFound exception.  I have attached a simple project that demonstrates the issue.  The steps to reproduce the problem are displayed in the sample application.

 We have traced the issue into the DataPresenter and can clearly see the issue, however it appears to originate from a PropertyChanged event, which has made it very challenging to catch the exception at any level where we can take mitigating steps.  We have been unsuccessful so far, and would appreciate any suggestions or advice on this, as it is a production-critical bug.

I will also post a question to the Ask A Developer support line, but wanted to see if anyone on the forum can provide a work-around or mitigating steps.

Thanks.
