Is it possible to databind the value of a RadProgressBar in XAML? For example:

    
            <telerik:RadProgressBar  
        
                 Name="PercentBar"  
        
                 Orientation="Horizontal"  
        
                 Margin="3"  
        
                 Value="{Binding Path=My_Percent, StringFormat=P0}" />

Seems simple, but this particular code throws the following error:

    
            System.InvalidOperationException was unhandled 
        
            Message: A TwoWay or OneWayToSource binding cannot work on the read-only  
        
            property 'My_Percent' of type 'System.Data.Common.DataRecordInternal'.

There is no example in the current documentation for the control.

Default Styles

Hi...

Do you have some where your default styles for the grid view ?

I can't manage to load them in blend and modify them, so I thought to manually insert them to my app.xaml.

MediaPlayer and/or QuickTime

Hi!

We have two issues concerning the title of this post:

1) We're porting an application from VB6 to WPF. In VB6 we're using QuickTimePlayer to play MP4 files, but WPF MediaPlayer does not native play them and there is not any Support/Control using QuickTimePlayer directly. Questions: Is there a way to get MP4 files running in MediaPlayer (ideally without installing huge codec packages)? Or is there a way to get QuickTimePlayer into WPF not using WindowsFormsHost?

2) In the WPF application we need to play video files from stream because they are cryptographically secured an will be encrypted while streaming to the player (because only the application itself should be able to play the files). Is there a way within MediaPlayer?

Thx!

RadDocking Object reference not set to an instance of an object when hosted in windows forms

Hello,

I'm running internal build 2010.1.326.35. When i host the RadDocking control inside of a windows form using a ElementHost I'm getting "Object reference not set to an instance of an object."

sample code.

    
            using System; 
        
            using System.Collections.Generic; 
        
            using System.ComponentModel;

                        } 
        
                        catch (Exception ex) 
        
                        {

                { 
        
                    public UserControl1()

                } 
        
            }

any suggestions for a workaround would be great. we have a conference coming up next week to demonstrate our product and this control is in all of our WPF maintenance screens.

Thanks much

Theme editing - how?

A client is keen to use a custom theme that does not closely match any of the out-of-the-box themes.

a. How can I easily modify an existing Telerik theme to create a new one?
b. Can I make standard MS WPF controls adopt such a theme?
c. Or, will some 3rd party theme provider also work with Telerik controls?

Many thanks for any guidance,

James.

Getting a Record ID from the selected item in a crousel.

Hi,
I have a carousel, and when i scroll , click through the items and then double click on a item, I would like to extract the value from the carousel. As I can't see anything obvious like you would find in a combo box.

For example I have a list of employees with a 'name' and 'employee id'. I select double click on a employee and i want to then be able to get the employee id.
