Databind PeogressBar example needed

[Art Kedzierski]

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}" />
