I'm working on styling our RadDocking controls and I am having a lot of trouble finding where in the styles the border around the central items in the DocumentHost is set.  It's the last thing I need to style for this control and I need some help finding it.  What style does that border live in?

I'm working on an application that requires us to overlay UI elements on a PDF background. We're trying to use RadPDFViewer as that background, but are having a tough time getting rid of the built in scrollbars.

Our ideal situation would be for both the RadPDFViewer and an overlay canvas to be children of a scrolling container, which can be zoomed in and out as well.

Are there any tricks to this or is this not something that can be done?

I have been having an issue ever since I started using the Telerik product suite, it's very rare, but it's absolutely driving me up the wall as I am absolutely dumbfounded as to what the cause is.

Every once in awhile, while navigating to a different page, I get this exception:

System.InvalidOperationException: Exception of type 'System.InvalidOperationException' was thrown.

This is something I have simply not been able to reproduce on a consistent basis, and something I haven't been able to isolate.  I will try to provide any other information that you need, but I just had to give posting this a shot as it is driving me insane.

Hi 
I have a property grid in my window and i want to control the property value change by an event such as ValueEditing.

Is this feature already supported?

Thanks,
Akram

This is a (somewhat) obscure issue that has been driving us nuts for months now, but we finally seem to have narrowed it down. The issue is that when we used the RibbonView as a Prism region and activated RibbonTabs in that region, the RibbonTab would occasionally fail to render. What I mean by "fail to render" is that the RibbonTab would get added, but would be completely empty; just a blank, grey tab.

We fought this for months assuming that we had a bug somewhere in our region management code. The problem even went away for some unknown reason, but came back just this week. After scratching our heads for a while, we figured out that if we set IsAutoSize=False on all our RadRibbon elements and made sure to set Size=<somevalue> then the problem would go away. If we tried to use auto-sizing then the problem would come back and even get worse as we made more and more elements use auto-sizing.

This appears to be a similar issue: http://www.telerik.com/community/forums/wpf/ribbonview/ribbongroups-not-visible-issue.aspx

So the good news is that we figured out a viable work-around. The bad news is that there appears to be an issue with how size is calculated. I'm sure the folks at Telerik can whip up their own sample to see what's happening. Meanwhile, we're just glad to have identified a solution that will let us roll into production.

Hi,

if I select a Row the Indicator doesn´t change!
The Arrow remains in the first-row any suggestions?

regards

I made a simple example:

Steps to reproduse:

1) Run this code

2) Scroll the grid down using right scrollbar

3) last row (marked "The last row") is half-visible (or invisible at all), despite of right scrollbar is bottom down (if you can't reproduce please set some another value in generate method)

4) Now scroll using mouse wheel. Everything is OK.

PS. I use Q3 without SP1 (will migration to SP1 fix this?)

Hi,

I have 4 ScheduleViews on one page to represent a particular concept in my application.
I have created a class that inherits from ScheduleViewDragDropBehavior.

How do I determine which ScheduleView is being subjected to the drop (the "sender") within Drop method?

Thank you,

I used the RadControlsScenario to create a Window just to see how it works and things went well until I tried to Compile and open it.   The first think I found was no RadControlsScenario.Show(), How do you show the window.  The second is The name 'InitializeComponent' does not exist in the current context.  My namespace is the same as the main window that would be calling it.

An object reference is required for the non-static field, method, or property 'System.Windows.Window.ShowDialog()'

Hi,

I am using both the silverlight timebar and kendo UI datepicker in the same page.
So, my requirement is to use both the controls(Timebar or kendo datepicker).
On changing the date in any one of the control(ex: timebar)  should deflect the same in other control(ex: datepicker).
On changing the kendoUI datepicker, I can trigger the radtimebar code behind and change the selectionstart and selectionend values.
But, the radtimebar is not rendered with the changed date.
Is there anything to refresh the radtimebar to display the changed content?
Greatly Appreciate your help on this.

Thanks in advance,
Nirmal Kumar Boopalan
