I have a cell with a dropdown and when I make a selection then move off of the grid by say, clicking on a button outside of the grid, I get an error because the cell failed to validate the new selection. an error msgbox shows up but when I dismiss it, the msgbox pops up again and there is nothing i can do other than kill the app.
It seems like when I dismiss the msgbox, the app wants to move the focus to the button but the cell fails to validate again and thus pops up the msgbox again and again.
It'd be nice if I could either prevent the focus to be moved away until everything is valid or somehow move the focus back to the grid after the initial error msgbox showing up.
What options are there?
Hi,
What version of the grid are you using? This sounds to me like a known bug that was fixed a while ago. Try getting the latest service release and see if that helps:

If I'm wrong and that does not help, see if you can reproduce the problem in a small sample project and post it here so I can take a look.
I am using 8.3.20083.2039.
If the issue was fixed after that, let me know. I will try to create a small sample.
I tried this out with the sample like you described and I am able to duplicate the issue. I'm not entirely sure that this is the same issue you are experiencing, but it's definitely something that needs looking into either way. So I'm going to forward this thread over to Infragistics Developer Support so they can write it up for developer review.
I am also having the same issue...I just wondered where I could find the solution if you already figured it out otherwise what will be the solution
There are a number of possible causes for something like this. If your grid is inside a ContainerControl which is nested inside another ContainerControl, then this is a known bug regarding the ContainerControl class, which was reported to Microsoft. As far as I know, there's no way around it other than to avoid using ContainerControl or derived classes. ContainerControl includes such controls as UserControl, SplitPanel, and the Tab control.
If you are not using ContainerControls, then this could be a bug in the grid or it might be a timing issue of some kind. Can you reproduce the issue in a small sample project and post it here so I can take a look?
We have the same issue with a couple different grid instances (v9.2). Could you provide a link to your bug submission to Microsoft so that we can better understand the nested UserControl issue?
Thanks!
Sure, here's the link:
