    Hi

    I am using RadProgressBar control inside a silverlight child window for a DB search operation, 
    My requirement is to close the child window once the search is completed i.e when the progress becomes 100.

    i am setting the dialog result value using event trigger
     <i:Interaction.Triggers>
            <ei:PropertyChangedTrigger Binding="{Binding CancelResult}">
                <ei:ChangePropertyAction TargetObject="{Binding ElementName=ProgressBarWindow}" PropertyName="DialogResult" Value="{Binding CancelResult}"/>
            </ei:PropertyChangedTrigger>       
        </i:Interaction.Triggers>

    I am able to close the child window using a button 

    <Button x:Name="CancelButton" Command="{Binding CancelSearchCommand}" Content="Cancel"   >
                    <i:Interaction.Triggers>
                        <i:EventTrigger EventName="Click">
                            <ei:ChangePropertyAction TargetObject="{Binding}" PropertyName="CancelResult" Value="False"/>
                        </i:EventTrigger>
                    </i:Interaction.Triggers>
                </Button>

    But i want to close the window  once the progress completed. so i am setting the CancelResult property to false once 
    the progress becomes 100 from the ViewModel, but the window is not getting closed.

    Hello Mahesh,

    We believe the problem is that the ProgressBar.ValueChanged event in not RoutedEvent and this is preventing the Event Trigger from working. The ValueChanged is from the RangeBase build-in Silverlight control so we have no option to improve that. Also I think the reason for not being RoutedEvent is because this will degrade the performance of the ProgressBar.

    I would suggest you use different approach instead of EventTriggers.

    Kind regards,
