    Hi, 
     I have RAD MenuItem as below -

     

     

     

    <telerik:RadMenuItem x:Name="testMenu" Header="Head" IsEnabled="{Binding IsIconEnabled}" ItemContainerStyle="{StaticResource CommonRadMenuItemStyle}" VerticalAlignment="Center" SubmenuOpened="FileMenu_SubmenuOpened">


    The Property IsIconEnabled when set in the code reflects in UI only once, later whatever times its set in code, its not reflecting in the UI. The property is complaint for INotifyPropertyChanged.

    Hello Harshal,

    We have implemented a scenario based on your code. When you click the button, IsEnabled property of two of the Items in RadMenu will change. Please check the attachment and inform us if you still have any problems or concerns.

    Why are you using the Mode as TwoWay for Binding? we are not updating anything from UI for this Property. Please remove the TwoWay binding and check.

    Hello Harshal,

    Currently this is the only way to set a binding for IsEnabled property. We have designed it this way as some limitations of Silverlight framework.

    We are sorry for the caused inconvenience. Do not hesitate to contact us if still have problems or concerns.

    All the best,

    Hello Harshal,

    I'm not sure I fully understand what is the problem. As I've already said, if you want to set Binding for IsEnabled property, you will have to use two-way mode. Could you clarify if you still have any problems setting IsEnabled for your RadMenuItems and what is your current problem? This way we'll be able to provide you better help. From your last mail it seems that when you set two-way binding and IsEnabled property is set to true for all items, no matter what you've already set in your viewmodel, but you can easily see from the project I've already sent you, that this is working correctly (some items are disabled at initialization, after you click the button, they are enabled).

    I'm looking forward to hearing from you.
