[Solved] Suggestion for Telerik on Grid performance

[Daniel Billingsley]

Like many other developers here, I have been very disappointed with the performance of the Telerik RadGridView when there is a little bit of templating done in the cells.  As has been stated previously in various threads, any LOB application is probably going to need to do this.  In fact, to the extent we developers are looking for simple plain grid, we could have just stuck with the native Silverlight grid.

I have an idea for you to consider though.  I wouldn't mind so much that it takes a bit to scroll the grid if there was some indication to the user.  As it is currently, it is just a horrible user experience.

Is it possible for you to implement something similar to the experience when DataLoadMode=Asynchronous to handle the scrolling.  What I mean is the grid would go to "busy" mode when the scroll button was pressed or dragged, and clear once you had finished painting the new layout.

Hi,

 Have you tried our latest internal build for Q3? I've changed our templates loading logic and the performance is far better now. If you want deferred scrolling you can set ScrollMode="Deferred" - will work both vertically and horizontally. 

Best wishes,

Thanks.  I'll look into those things.

I also already tried the custom column type workaround found in another thread, and it's probably sufficient for my needs.
