Running the latest 9/24 SP2 build.  I'm going to include alot of information because I'm honestly not sure what matters and what doesn't.. so forgive some of what may be superfluous information.

I have a datagrid that has its columns generated based on user configuration at run time. {using grid.Columns.Add(x);}

This data grid is 38 columns wide.  Currently 16 of those columns are configured as combo box columns.

10 of them have very short itemsource lists.  (5 - 10 items)
6 of them have considerably longer itemsource lists (900- 2000).

Horizontal scrolling performance is very poor in this case.  CPU spikes to 50% on a Core2 Duo 2.8Ghz with 3GB RAM.

the most common probles I've been informed of is the RadGridView is housed in a container that disables column/row virtualization.  Below is my grid configuration, and my RadGridView declaration



What can I do to increase the performance here?  From what I read in the 9/24 release notes, the gridview was supposed to improve performance in these cases.

Please look the attach files.Thanks.

Hi guys

Most developers will a combination of your and Microsoft controls to build their applications. However the themes that come with Telerik don't match the MS designs. For consistancy, would Telerik expand their current skin files to include theming of the other MS and toolkit controls?

That is, it's useless to use your skins when they make your controls quite different from the rest of our applications.

I'm using the RadWindow static methods for Prompt, Alert, and Confirm.  Everything works great, but since they are static methods, I don't see any way to change the window's theme or style.  I can see in the WPF RadWindow demo that it is being done, but I can't find any code that seems to reflect how the theme is set.  How is this being done?  Is it some application level setting that is being changed?  If so, what if I don't want to apply the theme that I want for my RadWindow to the rest of my application?

Hi,

I have only one RadPane in the RadPaneGroup and it's set to AutoHide. I need to set up an event for sliding-out or sliding-in by user's mouse actions. There are some setting in my program that I need to change whenever the RadPane is being shown or hide. I tried all the available events but none get triggered when I hover my mouse over the Tab and the RadPane starts sliding-out and vice versa.

Thanks,
Ramin

Has anyone tried to include Winforms and WPF controls in same  Winforms project using Telerik's controls?
I was just curious about what experiences users have had while trying to upgrade  project based on  RadControls for Winforms, by including some WPF controls.

Thanks

Hi,

I have a tree control sometimes when select a item and go for deleting and before deleting
I check the count,since I am expencting the count to be 1 (trvOutputTree.SelectedItems.Count())
it says count is two, first item is a always DependencyProperty.UnsetValue.
I checked this link: http://msdn.microsoft.com/en-us/library/system.windows.dependencyproperty.unsetvalue.aspx

but dont in this case why its showing this? Are you guys internally using it somewhere?

Thanks,
Bala

Hi,

Is it possible to allow more decimal digits if the user enters more. Say I have NumberDecimalDigits=2 and the user types in 10.123, then the control will show 10.12. I would like it to show 10.123. But if the user types in 10, I would like to show 10.00 (so I can't just change NumberDecimalDigits to 3).

Any suggestions?

Thanks!
