Hi All,
I am getting a un-handled exception when selecting one or more row in ultragrid and ctrl+dragging. Problem is unable to handle this issue and unable to find the source.
But after handling the application I got the following stack trace
System.NullReferenceException: Object reference not set to an instance of an object.

Can any one help me to fix this issue or is there any service patches available to fix this issue
Currently I am using
Infragistics2.win.ultrawingrid.v8.2
File Version: 8.2.20082.2204.
Kindly help me to find a fix for this issue.
Hi,
I tried this out in a simple sample project and it works just fine for me. I don't get any exceptions.
So this is probably related to something in your code or some specific property settings you are applying to the grid.
I'm attaching my sample here so you can try it out.
I'm afraid that without knowing the cause of the issue, there's not very much I can think of to help you get around it.
You appear to be using the latest service release for version 8.2, but even so, it is almost 3 years old. That version is no longer being updated. So you might want to consider downloading a trial of the latest version of NetAdvantage and see if the problem has been resolved.
Hello,
I see the same stack trace with exception for this related scenario:
-The grid is set to MultiSelect (Grid.DisplayLayout.Override.SelectTypeRow = Infragistics.Win.UltraWinGrid.SelectType.Extended;)
-The grid has a column with (MergedCellStyle = MergedCellStyle.Always;)
-The grid contains several rows. The column that is configured as “merged” has merged data values.
If I initiate a CTRL-drag/drop in a cell with merged data, I get the same exception and call stack as above (see below).
Do you have recommendations as to how to resolve?
FYI: I don't see the same exception when the grid selection is set to single select instead of multi select
Thank you,
Hello Carl,
I tried this and it always works fine for me so I attached my sample to this post for you. Please review it and feel free to let me know if I misunderstood you or if you have any other questions.
Boris,
Given my earlier reply on “Fri, Oct 5 2012 11:40 AM”, do you know what is causing the exception?
Thank you.
Carl.
I took some time researching this and was not able to get this behavior in 12.2. Are you sure that you are using the latest service release, it is 20122.2010?
If so, could you please shoot a video and upload it archived(as zip), so I could see exactly what you are doing, I might be doing something wrong. Thank you in advance!
Hey Borris do you have any insight into what we could do to fix our issue?
We've now upgraded the Ingragistics version to 12.2 (demo release) and we're still seeing the issue. The same test case produces the exceptipn on the latest version as well. Could you please take a look, thanks.
Thanks Boris, we do not need any more assistance. We will try a newer version of Infragistics at a later date to see if the problem is resolved. Thank you for your help.
Regards,
Carl
I am checking about the progress of this issue. Please let me know If you need any further assistance on this.
