So I seem to have a memory leak. I am using JustTrace and Memory Profiler.  What happens is in using the RadListBox on one of my views, I see InternalScope objects keep adding up everytime I open the view that has that RadListBox.  But I don't know what that class is used for or what would make that problem?  Any detailed help on how to find the root of this problem would be appreciated.  Been trying to figure it out for days and have commented out templates and styles.

Hi!

I would like to suggest that page numbers and a page title be optionally added when exporting a GridView to Pdf. This should be easy to implement since RadSpreadProcessing already has a class "HeaderFooterSettings". Just expand the "GridViewPdfExportOptions" with two options: ShowPageNumbers (true/false) and PageTitle (string). Should be done in no time.

I had browsed for a similar issue & seen the below link which had the same issue of mine, its said by Telerik that issue is resolved but I could not get the fix anywhere.

http://www.telerik.com/forums/radwindow-autosize-on-runtime#e9i78SNv102TDO2DCh_z6g

I have created a RadWindow and its content is set to a wpf view which has some controls & a RadExpander. I want this RadExpander to be shown when its expanded(my RadWindow Width should be resized accordingly).
I have set ResizeMode="NoResize" and SizeToContent="True" for my RadWindow. But RadWindow doesn't seem to adjust according to its content, how can I achieve It?(I have not set any Height or Width to my RadWindow)

Is SizeToContent changed to Enum to support WidthAndHeight or what is the fix for the problem given??

Hi,

I'm talking about class "Slot" in Telerik.Windows.Controls.ScheduleView namespace.

Let's take a look to Slot(IOccurrence occurence) constructor, line 14 may cause NullReferenceException:

Using the sample below, how would I get the "VendorName" property to display next to the values of each series in the trackball info popup, just like it would appear in the legend?

I have a question about Telerik UI for WPF, i want to achieve a number of real-time monitoring curve, here is my code:

Actually, I'm referring to your example，but I cannot achieve the goal(my English is not good)

I ask you to help me see what the problem is，

Thank you very much.！！
