CanUserSelect not working with keyboard arrows

Hello,

On a grid, I set CanUserSelect to false. It works fine for mouse selection (the user cannot select a row with the mouse) but not with keyboard arrow keys.

Let me describe how to reproduce it: if you click on the grid (nothing is selected) but the grid gets the focus. Then, you use the arrow keys (up or down) and it selects the row just where you clicked (and not where the last selection was set in code)!

So, not only the user can select a row with the keyboard but "something" is also selected when clicking! Even if the selection doesn't change, the row that was clicked is still saved somewhere.

Is this a normal behavior? Am I missing an option on the grid to disable the keyboard select?
If it's a bug, do you have a workaround and when will it be corrected?

Best regards,

Daniel

EDIT: I forgot to specify that we use the Q1 2010.

Is StyleManager preventing Windows from being collected (GC) ?

Hi.
We encountered a problem using the StyleManager.
We designed a (long-living ?) app which opens and closes Windows (frequently ?).
The App is running like 7 hours a day (as a try Icon) and the user con Open different Windows.
When the App starts it sets

    
            Telerik.Windows.Controls.StyleManager.ApplicationTheme = new Telerik.Windows.Controls.Office_BlueTheme()

When a user openes a Window he manipulates some data and closes the Window again.
For some days now we have been searching for a memory leaks (the memory in use seemed to grow)...
It turns out that no Window (and from there no controller/presenter, adapter, repository, entity-context, data-object) will ever be garbage-collected.
Upon further investigation the leak disappeared when we commented out the StyleManager-Line.
Using clr-profiler we were able to determine that references are in place from root to all/most telerik controls (and from there to the containing Window) when using an ApplicationTheme.

Ist there a way (apart from running every window in it's own AppDomain) to set a theme on aplication-level and make use of garbage-collection ?

Yours,
Nils

How to create a different turing animation for book title

Reordering rows when finished editing

Hi guys,

I've got a telerik rad grid view data bound to a BindingList<items> with group descriptiors enabled and it seems that when I edit a cell and then commit it, the row gets shifted to the bottom of the current grouping.

Any ideas?

Cheers,

Tim.

Maximized RadWindow hides Windows Taskbar

Hi,

We've noticed an interesting behavior - when the RadWindow is maximized it hides the Windows' taskbar. Did anyone else run into this? Is there a simple solution for the matter?

Thanks,

GridView throws design time error after solution is upgraded to VS2010

I have a gridview in a window that displays/loads fine, in design view, for a VS 2008 solution. i have upgraded the solution to VS 2010 and now receive the error below when in design view (still runs without error, just design time error).

System.NullReferenceException

Object reference not set to an instance of an object.

Binding the Header property of a GridViewColumn

Hi,

I need to do something like the following :

<r:GridViewColumn Header="{Binding Path=Whatever}">

<r:GridViewColumn.CellTemplate>

</DataTemplate>

</r:GridViewColumn.CellTemplate>

</r:GridViewColumn>

It doesn't work. There's no binding error displayed to the Output Window (normally, all binding errors are displayed there). The header is just plain empty in my grid. Before you tell me that the property may not exist, I must add that I also tried {Binding .} (or {Binding Path=.} if you prefer); at least, it should display the ToString value of the current DataContext, whatever it is, but again, nothing is displayed.

Thanks in advance
