Hi,

I have a pie chart set up, and I've been following the tutorial at http://www.telerik.com/help/wpf/radchart-features-chart-legend.html to set up the legend. I have the UseAutoGeneratedItems set to true for the legend, but the items in the legend are showing as "Item 1", "Item 2", ...etc. Isn't the auto generation supposed to use the categories that the chart is set up to use? Here's the code for the chart:


Thanks!

Hello,

I have two questions
 1. when I set a radsplitcontainer.InitialPosition to floatingonly, in visualstudio i can't use "design mode".
 2. when i execute my application, the title of others radpane are empties... (i can't reproduce it in a small project for the moment), but maybe have you an idea of why it would be possible.

I obtain the following trace for point 2 :


I obtain the following error for 1. :

Hi!

I need to set some document information keys of an exported PDF-file.

In an exported PDF-file, all I can see are some hardcoded(?) properties like Producer="Telerik RadRichTextBox" and Creator.

How can I set Title, Subject, Keywords, Creator and Author of the exported PDF-File?

Thanks!

I have a flag enum that contains more than 32 flags so I set the underlying type to be long (Int64). When I set the RadPropertyGrid.Item to an object which has a long flags property, I get an OverflowException: "Value was either too large or too small for an Int32." (originating at Telerik.Windows.Controls.Data.PropertyGrid.FlagEnumEditor.OnEnumTypePropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) ).

Is there a way for the property grid to deal with enums whose underlying type is Int64 (or some other type > 32bit)?

Hey,
Just a quick question - in the WPF demo application, when You download it and it loads for the first time it displays a line loading and massive numbers going up. Is that done with one of Your tools provided ? and If yes which is it ?

Hello,

I'm just curious,  I always post questions between 10-5 Pacific Time (UTC -7) and they seem to be answered when I come back in the morning.  What time zone are you guys posting from?
