Guys, the xamDataGrid occassionally throws the following exception causing my application to crash. What exactly does this mean?

Message : Index was outside the bounds of the array.

Stefan, this was posted a long time ago and there has been several releases since then. I also have not ecountered the problem recently, so it may have been fixed. If not, i will open a support ticket as i am also doing the appropriate checks to ensure records are accessed within the valid range.

Hello knji,

Thank you for your post. I have been looking through it and I assume you trying to get a Record from the Records collection by its index and when that index is out of bounds you get the described exception, so I suggest you check the Count of your Records in order to see if the one you want to get exists. Please note, we are making efforts to ensure that all forum posts are answered by an Infragistics expert. We believe that the other community users may benefit as well.

If you have any further questions feel free to ask.
