  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.

  Found the answer:
  
  

  <telerik:RadProgressBar

  Name="PercentBar"

  Orientation="Horizontal"

  Margin="3"

  Value="{Binding Path=My_Percent, Mode=OneWay}" />
