CloseRadWindow TriggerAction

[Joseph Gershgorin]

I found it a little annoying that I had to drop to code behind to just have a button do nothing more than close a RadWindow it. It's fairly easy to encapsulate this into TriggerAction.

For this to work you should have installed and referenced System.Windows.Interactivity from the Blend 3 SDK.

Here's the Behavior:

using System.Windows;
using System.Windows.Interactivity;
using Telerik.Windows.Controls;

namespace Mass.ThirdParty.Telerik.Behaviors
{
    public class CloseRadWindowTriggerAction : TriggerAction<FrameworkElement>
    {
        protected override void Invoke(object parameter)
        {
            var radWindow = RadWindow.GetParentRadWindow(AssociatedObject);

            if (radWindow != null)
            {
                radWindow.Close();
            }
        }
    }
}

And here's how to use it in XAML:

<Button Content="Close">
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="Click">
            <Behaviors:CloseRadWindowTriggerAction />
        </i:EventTrigger>
    </i:Interaction.Triggers>
</Button>

Hello Joseph,

Thank you for sharing your thoughts! If the button that should close the RadWindow is within the RadWindow control you may use "out of the box" the following approach to achieve the same result:

<Button Content="Close!">
    <telerik:CommandManager.InputBindings>
        <telerik:InputBindingCollection>
            <telerik:MouseBinding Gesture="LeftClick"
                    Command="telerik:WindowCommands.Close" />
        </telerik:InputBindingCollection>
    </telerik:CommandManager.InputBindings>
</Button>
