Hi, I'm currently going trough the process of styling the PanelBarItems and I can't get the mouse over on the currently selected item in the PanelBar.
Repro :
1.MouseOver item1, it works
2.Click on item1, mouse over style is still applied
3.mouse out and back in item1, mouse over style is no longer working.

Hello,
I am using a RadGridView. I set my source to an ObservableCollection of objects that represent my rows of data. During run time, rather than seeing the value of property in the column cells, I see System.WeakReference.
Any clue as to what this could be due to?
Thanks,
Brian

I'm building a WPF application that will be running on laptops mounted in police cars. The colors need to change when a user clicks on a button, one set of colors for Day time and another set for Night time. The idea is that the night time colors will be easier on the user's eyes in a dark police car at night.
I've implemented themes in my application. I use them to switch between "Day Time" colors and "Night Time" colors. This is done by switching between two different ResourceDictionaries, one for Day Time and one for Night Time.
I'm using a RadTabControl in my application and I cannot get its headerr to swap colors at all. Using Expression Blend, I've made a copy of the RadTabControl's template. Using Snoop, I inspected my program's visual tree and found that changing the background color of the Border control named "HeaderBackground" would change the background color of the header row. So I edited the copy of the RadTabControl's template and put my values into the template for that control, as shown below:
This does not have the desired effect, however. It appears that the {DynamicResource xxx} values I've specified are overridden somewhere, because every time I run the program and change to night mode, the colors do not change.
What am I doing wrong here? What is the correct way to do what I want to do? Here's the XAML for the RadTabControl in my program:

Hi,
I have a little problem with my scroll on RadGridView. One of my column's cell template is RadTreeView. When mouse is over tree, mouse-wheel move does not take affect on RadGridView scroll. When mouse is over any other cell, mouse-wheel scroll works correct, like always. It looks like RadTreeView inside cell is stealing mouse-wheel event and RadGridView doesn't scroll? Because my cell height is adjusting itself to RadTreeView size, there is no scroll bars inside cell, it is ok, I want scroll only on RadGridView.
Thanks for any help!

I have a RadDropDownButton which DropDownContent is a StackPanel (which in turn contains other controls).
The issue I am having is, defining a Tooltip for the RadDropDownButton results in the Tooltip also being displayed on the dropped-down StackPanel (except for any position that then contains another control).
The intent is only to display the Tooltip on the button itself, and not on the resultant StackPanel that flies out when the button is pressed. Currently the workaround is to have an image displayed on the button and then have the tooltip attached to the image. But, I would like to know if there is a better fix for this.

As the title says, when I bind an ImageColumn to a URL which points to a an image on the web, I get an exception in the event of the image not being available (for example if the server is down). Is there any way to prevent this?
