Hello!

I have a problem: I want to get image from chart on service. I use ExportToImage method to do this. By default - it's work fine. But when I try to apply any style to the chart (i.e. set Axis title style for changing font size, I using Axis.AxisStyles.TitleStyle property) I get following error:

WcfDataService.Code.PdfGenerator - Couldn't get chart snapshot.
System.Windows.Markup.XamlParseException: '11' is not a valid value for the 'System.Windows.Documents.TextElement.FontSize' property on a Setter. ---> System.ArgumentException: '11' is not a valid value for the 'System.Windows.Documents.TextElement.FontSize' property on a Setter.

Can you help me? What can I do to fix this problem?

Hello Telerik Team,
                                 I have some problem in Debugging.Here in my WPF project using telerik rad controls.if i am using  windows application mean easily find out error using line by line debugging.

but i am not able to debug wpf project. is it any problem when i am using telerik controls?

I want to prevent dragging items to the same level as the root, how do I do this?

thanks.

Greetings,

I am trying to upgrade my telerik wpf controls to the latest build according to this article: http://www.telerik.com/help/silverlight/installation-upgrading-from-trial-to-developer-license.html

So first I want to remove telerik controls from gac. And here is the problem. In my VS 2010 I can see telerik libraries in .NET tab when adding a reference (see references.png). But when I try to run gacutil -u Telerik.Windows.Controls.dll as metioned here: http://www.telerik.com/help/wpf/installation-deployment-add-remove-to-gac-wpf.html I get this message: 

No assemblies found matching: Telerik.Windows.Controls.dll
Number of assemblies uninstalled = 0
Number of failures = 0

So how can I upgrade my telerik radcontrols for wpf?

Thank you in advance
Miro

I have added a handler to VisibleRangeChanged event to query the database for appointments within the new date range. However, the appointment source that is updated does not get reflected on the current view. If I switch to another view and back again, I see the appointments.

Is there a way to fix this so that I see my appointments when the AppointmentSource is udpated?

Thanks,
Rod

This is happening on what appears to be a ListBox inside the filter that contains a CheckBox element for each distinct RowValue in the column.  
When scrolling, the width of the ListBox changes depending upon the size of the widest checkbox in the list.  

Also, the only way to use the scroll bar is to click either the up or down arrow, wait for the ListBox to resize, then click the arrows again.  Attempting to move the actual bar of the ScrollBar does not scroll the ListBox with CheckBoxes, it instead scrolls the bar of the GridView itself. 


Is there a way to set the ListBox width to that of the widest CheckBox?

I have an integer type property, which may only have specific values in a infinite sequence: 4, 6, 8, 12, 16.... (the sequence can be made finite because big values will never be used in this reality).

Q1: I would like the mouse wheel and the buttons to select the next valid value for the user. I saw this post (http://www.telerik.com/community/forums/wpf/numeric-up-down/use-numericupdown-as-multiplier.aspx) in the forum and figured that my problem cannot be solved either. Is this feature planned for any release?

Q2: The numericupdown should be readonly under certain circumstances (most other input-fields are textboxes and they are made readonly, not disabled). Is there some setting to remove the possibility of user input from numericupdown besides enabled=false?

Thanks,
Inger Marie

Hi,

I'm working with the RadTreeListView however rather than displaying one row for each item in the expander column I'd like to display multiple rows and have the item in the expander column span those rows e.g.

| Item          | Metric    | Value 1 | Value 2 | Value 3  |
| > Item 1    | Width    | 14         | 13         | 17          |
|                 | Height   | 3           | 8           | 89          |
|    > Item 2| Width    | 34         | 89         | 22          |
|                | Height   | 33         | 58         | 92          |

I'm wondering whether anyone else has needed to do this and found a solutions or whether anyone would be able to point me in the right direction on which templates I need to amend.

Thanks,
Derek
