Hi,
just was playing around with the new image editor. i'm using a custom ui like the one in the demo (the one with the image of the baseball player) and i was wondering if there is a way to set the height and width of the cropping rectangle to a specific size.i want to force the user to crop his images to a predifend size or at least aspect ratio. similar to the way you assign contact images on a iphone.
and one more question, how can a write the RadBitmap to a byte array for storing it in a DB?
UPDATE: OK, forget about the DB thing, just found the

Hi Telerik,
When using RadSchedueView, I'd like to use the predefined category list and assign a category to the appointment dynamically. This list is defined in RadScheduler. When I added these two references, it had name conflicts. How can I use this predefined list in ScheduleView?
Thanks.

I am trying to make multiple changes to an observablecollection that is bound to a gridview.
Using linq to locate the items and then making changes.
It seems to work because I loop through in break mode and see it meeting the condition and setting the items Status value for the exact count of items that I am searching for, but I am not seeing changes reflect in gridview that has itemsource of the collection.
I assume since the collection is bound to the grid's ItemSource that it would update the grid automatically... does there need to be a manual update after the update takes place?
Is there a better approach for performance or clarity reasons?

// grid.ItemSource = gridItemCollection (ObservableCollection<T>)
var itemsToUpdate = gridItemCollection.Where(item => item.Status.Equals(statusToChange)); foreach (var item in itemsToUpdate) item.Status = newStatus;I assume since the collection is bound to the grid's ItemSource that it would update the grid automatically... does there need to be a manual update after the update takes place?

What is the property that controls the width of the Menu bar ?
This what I have:
<DockPanel> <k:Menu DockPanel.Dock="Top" > <k:AddMenuItem Command="{Binding Path=CommandAdd}" /> But the Menu bar is only as wide as the menu items in it... (?)
Thanks,

I am running the Q2 version of Telerik Rad WPF and cannot open the xaml file Expressoin Blend 4. I have never tried it again, so I am wondering if I should be able to or not. The error I am getting is, The element "[RadTabControl]" could not be displayed because of a problem with Telerik.Windows.Controls.RadTabContol: Cannot create an instance of "RadTabControl".
The inner exception is
The type initializer for 'Telerik.Windows.Control.RadTabControl' threw an exception.
Below that is could not load type 'Telerik.Windows.Controls.ThemeResourceKey' from assembly 'Telerik.Windows.Controls, Version 2011.2.712.1040, Culture=Netral, PublicKeyToken= 5803cfa389c90ce7
Is this a configuration issue, or are the telerik controls just not compatable with Expression Blend 4?

Hello,
in order to fix another issue, I have upgraded to 2011.2.0725.40. My application used RadWindow.ShowModal and the second (!) window that is opened (after the first one is closed again) throws an exception as soon as the window is resized or dragged (both of which call BringToFront, as it seems). I noticed that in previous versions the window would get removed from the list of windows returned by RadWindowManager.GetWindows() as soon as ShowDialog() returns, in the newest version, it remains in the collection.
Update after further research: I have reproduced the problem in a sample application, and found that this only happens if I have my configuration set to Any CPU, which would execute in 64 bit in my case (Win7, 64bit). If I switch to x86, and enable break on any exception, I still get the exception, but the program continues without problems. My guess is that the exception ends up unhandled in x64 mode.
Any Ideas?
Regards,
Karin

Trying to figure out how to provide a control on a custom GridViewBoundColumnBase derived class to switch into edit mode for the cell. During non-edit mode, the contents is a clickable link. This makes it impossible to switch into edit mode. I'd like to just put a little button in the cell to switch to edit mode.
To do this, I need to figure out two things within the CreateCellElement method: whether the column is ReadOnly, and how to raise a BeginCellEdit event of some fashion. BeginEdit switches to edit mode for the row, but not for the cell.
Can ya'll help me out on either of these?

Hello, I have the following problem:
When you double click a row or press enter, the RowActivated event fires and gives you a RowEventArgs.
However, in the case of the enter key, the RowEventArgs has Row=null.
How can I find out which row was selected?
Thanks.
