binding buttons to ribbon groups

hi,

I am trying to create a ribbon menu from a json file. Tabs ands groups are being displayed. But buttons are not. instead, the class names of the buttons are displayed as text and they can not be clicked. what could be the reason ? any example of such system would be appreciated.

so here are my business objects:

01.public class RibbonTab {

02. public string header { get; set; }

03. public List<RibbonGroup> ribbonGroups { get; set; }

04.}

05. public class RibbonGroup {

06. public string header { get; set; }

07. public List<RibbonButton> ribbonButtons { get; set; }

08.}

09. public class RibbonButton {

10.

11. public string text { get; set; }

12. public string icon { get; set; }

13. public int size { get; set; }

14. public string parentPage { get; set; }

15.

16. public string ButtonText { get { return text; } }

17. public Telerik.Windows.Controls.RibbonView.ButtonSize ButtonSize

18. {

19. get {

20. return (Telerik.Windows.Controls.RibbonView.ButtonSize)size;

21. }

22. }

23.}

here is my view:

<UserControl.Resources>

<Style TargetType="{x:Type telerik:RadRibbonButton}">

<Setter Property="Text" Value="{Binding ButtonText}" />

</Style>

<Style TargetType="telerik:RadRibbonGroup">

<Setter Property="Header" Value="{Binding header}" />

<Setter Property="ItemsSource" Value="{Binding ribbonButtons}" />

</Style>

<Style TargetType="telerik:RadRibbonTab">

<Setter Property="Header" Value="{Binding header}" />

<Setter Property="ItemsSource" Value="{Binding ribbonGroups}" />

</Style>

</UserControl.Resources>

<telerik:RadRibbonView ItemsSource="{Binding RibbonTabs}" />

Copy data without format

Is there a way to copy/export the data in a GridView without applying DataFormatString? We have custom formatting on some values and when pasting the values in Excel it's not able to parse them correctly.

I guess that the issue lies in Excel, but a value that is displayed in the RadGridView as "2 250,00" (DataFormatString = "N2", Swedish culture) is parsed as a String when pasted to Excel, and it's impossible to apply any other format until I remove the thousand separator (even when Excel is using a format with a thousand separator).

We're currently copying to the clipboard in Html-format, because some cells contains text with linebreaks, and this seems to be the only way to keep them without breaking the rows.

Image Orientation Issue: RadImageEditorUI

The image I'm working on has some metadata because of which the landscape photo is displayed portrayed. User can rotate once loaded, but what I'm trying to achieve is load the image with proper orientation in first place. I have tested my C# code to read the metadata orientation of image and correct it accordingly to load it properly in normal WPF image control. But I'm having problem using the same code in the Telerik RadImageEditorUI. Basically, I'm looking for an event that could be raised when user selects open>select image from radImageEditorUI dialog box, which then I can use to handle the orientation handling code.

So, my question is, is there something in Telerik RadImageEditorUI that can handle the orientation issue when loading image? or Is there some kind of image loading or image selected event raised?

Customizing the Connection Manipulation Adorner

I created a custom diagram shape style that has the content presenter above the shape. The shape looks great until I select it or attempt to create connections to it. I want the selection box only around the shape and not the text. The connectors are also not attached to the connection points on the shape. I have included some images of the issues I am seeing. I assume it has something to do with modifying the manipulation adorner to target the shape within the DiagramShape rather than the entire DiagramShape.
