Performance Issues when using readonly checkbox columns

[Sasa Milovic]

Hi

The grid seems to slow down alot when I have a few checkbox columns and I display the grid fullscreen. I've testing by removing and adding columns using the column chooser, and the grid is only slow when the check box columns are present.

I am binding a a generic list to the grid.

I am doing the following when initially creating the grid (setting the columns to readonly), and removing this code does improve that responsiveness

For Each col As GridViewColumn In grdProdArea.MasterGridViewTemplate.Columns

col.ReadOnly = True

Hi Sasa Milovic,
Indeed we are aware of these performance issues and we are working on them. The behavior you have observed is because the text cells are optimized, and the embedded editor columns (like the checkbox columns) are not optimized for the SP1 release.
