HI,

Please make sure that the new data you use to populate the grid has the same schema. If not then the values set to the DataMember attributes may not match any field in the data source and result in the error you see. If you need any further assistance with this please make sure that you provide your grid markup and the code behind logic that interacts somehow with the grid.

Hi,

Thank you for sending me this information. It looks like it is not because of your .Net version.

I have tried to reproduce the issue, but I cannot.

I have attached the sample project I used to test this. Please test this project on your side; whether or not it works correctly may help indicate the nature of this issue.

If this sample project is not an accurate demonstration of what you're trying to do, please feel free to modify it and send it back, or send a small sample project of your own if you have one.

Please find the attached file..

Hi,

I am asking about the.NetFramework version not the version of infragistics controls.

Here is how you can check the .Net version installed (https://msdn.microsoft.com/en-us/library/hh925568(v=vs.110).aspx):

1. On the Start menu, choose Run.

2. In the Open box, enter regedit.exe.

   You must have administrative credentials to run regedit.exe.

3. In the Registry Editor, open the following subkey:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full

4. Look at the version

You can look in the attachment which is mine.

INFRAGISTICS NETADVANTAGE 2003 Vol 2 Version is 3.2
