RadGridView Column Display Error

[Edward Chen]

Hi,
After attaching a datasource to a radgridview , I apply best fit on the entire grid. But sometimes my grid behaves wierd and gives me something like the attached image. Please help.

Thanks a lot

Hello Edward,

Please could you give some further details on your error. For exmaple, any special grid settings that you are using, such as AutoSizeRows etc.. and if you can post a small sample that replicates the issue, then that would also help

In the meantime, here is a sample that you can try in a new project. Please let me know if this works fine for you.
Thanks
Richard
