I need to be able to filter the RadGridView based on a collection property on each item. Here is a sample to illustrate my case. Let’s suppose that each item in the grid is of type Person and each person has a collection property ScheduledMeetings. I need to apply some kind of filter that does the following:
People.Where(p => p. ScheduledMeetings.Contains(someMeeting))
which will return all people participating in the specified meeting.
The documentation samples all use the built-in CreateFilterExpression method of the FilterDescriptor class. So my first choice was to use the existing FilterDescriptor class in combination with FilterOperator.Contains but it seems that ‘Contains’ only works with strings and not with IEnumerable (even with FilterDescriptor.MemberType specified)!
I suppose I need to implement some custom FilterDescriptor class inheriting from FilterDescriptorBase and then provide the Expression from the CreateFilterExpression override. But how do I create such expression?

Hello,
I'm playing around with the Slider control and im trying to find a way to customize it. Basically all I'm looking for is to increase the actual slider bar to approx. the same height as the thumbs themselves to give it more of a sliding progress bar look. Also maybe customize the sliders themselves a little bit. Is this possible somehow using WPF?

Hi I have issue whit theme changing in RadDock control. When I use StyleManager.SetTheme method for different controls everything works fine. But if I do this with StyleManager.SetTheme(myDock,new Windows7Theme()); then this method destroys the layout and disables the layout loading (to recover previous layout). App hangs and layout doesn't recover correctly. I need to implement the dynamic themes changing but RadDock doesn't seem to work fine.

Hopefully someone can shed some light on these issues for me.
I have 3 states for my listitems (normal, clicked, highlighted) and would like these states to expand the entire length of the treeview control on mouse hover, selected, unselected. I would also like to remove the expand buttons and have the treeview expand when a user clicks on the main item. I found this example and thought there had to be an easier way for the treeview selection. I hope there is! Any help would be most appreciated.
The good news is that I got databinding working :)

Thanks in advance

Can someone describe the easiest way to edit the style of the scrollbar.
I tried with Blend but it only changes background color which is not enough. I want to restyle everything, like bars and buttons, including style when clicked and dragged and hovered (Like any other style).
How can I manage this without too much work (E.q. creating a new theme).
Seems this is not in the styles in Blend???

Hi,
I'm using BringDataItemIntoView to go to the item i reselect after i refresh my grid.
But now i have a problem with when you select an item in the grid that is already visible (no scrolling required) and there aren't enough items to make the grid scroll.
So what happens the grid sets the selected item to the first row visible and the records above aren't shown any more and there isn't a scrollbar visible.
For example
If you have 3 records in the grid and you call the method BringDataItemIntoView on the third record, then this will put the 3 record to the first visible record in the grid but the 2 records above aren't visible any more and there also isn't a scrollbar (using the mouse wheel does the trick for scrolling)
Any ideas how i can fix this?
