Hi,
I am getting this error, but I can't why what I did wrong. Does anyone know what this mean? Thanks you.

I have the same problem when I try to export a grid with the GroupBy option active. Have you solve the problem? If yes, could you tell me what's the problem?.
I' m working with Infragistics V5.2.
Thank you
Alberto
Hi Alberto,
I am invoking Update() on the grid before setting Fixed = true. Looks like it's working.

I have a sample project that reproduce this exception, where could I send it ?
Thanks

The easiest thing for you to do is to just attach a zip file to your post. Go to the Options tab while posting to attach a file.
If you don't want to post the same on the forums, then you will need to send it in through Developer Support.
yesterday I had the same problem. In my case I try to change the grid layout..I have installed the last SR (NetAdvantage_WinForms_20101.2102_SR.exe), but the problem persists. Has anyone found a solution ?

I'm getting this exception when I place more than one column header into the Group-By area at run time.
As a workaround, the error does not occur if each column header is initially added to the Group-By area as the innermost grouping. After adding a column as the innermost grouping, it can be moved to another position within the Group-By area without error.
I had never encountered this error until I added several Formula summaries to the grid. The grid has always contained several non-Formula summaries, and all summaries display the expected results. The error occurs regardless of whether the columns placed into the Group-By area have a summary.
I'm using version 2009.2. Has this issue been fixed in a newer release?

It's hard to say without knowing exactly what the issue is and seeing it in action. You could try downloading a trial version of the latest version of NetAdvantage to test it out. Or if you can post a small sample project here that demonstrates the exception, I would be happy to try it out in both versions.
Before you do that, though, try setting the FormulaRowSourceIndex to either RowIndex or ListIndex and see if that helps:
private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e) { UltraGridLayout layout = e.Layout; UltraGridBand band = layout.Bands[0]; UltraGridOverride ov = layout.Override; ov.FormulaRowIndexSource = FormulaRowIndexSource.RowIndex; }
