I have a grid with virtualization on and with multi-line data in some rows, meaning the row height's are not the same throughout the grid.  When more data is added, the grid will scroll automatically for no reason.  For example, the grid is scrolled so that the 10 row is the topmost.  Added more data to the bottom of the grid and the topmost row is not longer the 10th, although the existing data in the grid did not change.  

 

There is no TopMostRow property and the scrollbar offsets do not change although the view-port offset definitely did change.

 

A well behaved grid would only modify the scroll bar itself to indicate more data in the grid.

 

Any ideas?

 

Thanks much

Hi John,

Thank you for your interest in the RadGridView component.

I do agree that the behavior you expect would be the correct one. However, I was not able to reproduce the behavior you are experiencing on your end. Attached to my reply you can find the sample application that I prepared for my tests. Can you please check it out? Would it be possible for you to modify it in a way that mimics your setup and send the updated project in a new support thread? I will gladly assist your further.

Best Regards,

Here is a small sample project that recreates the issue.  Thank you for your time.

Update - My attachment was denied!

I don't think renaiming my .zip file to .png will work.  And a picture file is not worth the thousands of words my working sample would be if your site would allow me to upload it.  Let me know how I can get this to you.  Thanks much.
