TelerikWindow trigger function when using escape key

[Martin Herløv]

I would like to call a function every time the window closes. No matter how the close was triggered.

<TelerikWindow Width="900px" Height="fit-content" Centered="true" Visible="@(Details.BaseData.Id > 0)" Modal="true" CloseOnOverlayClick="true">
    <WindowTitle>
        <strong>@Title</strong>
    </WindowTitle>
    <WindowActions>
        <WindowAction Name="Close" OnClick="OnFormClosed"/>
    </WindowActions>

Hi Martin. 

Did you tried using VisibleChanged event? 

<TelerikWindow Width="900px" Height="fit-content" Centered="true" Visible="@(Details.BaseData.Id > 0)" 
Modal="true" CloseOnOverlayClick="true" VisibleChanged="@VisibleChangedHandler">
<WindowTitle>
<strong>@Title</strong>
</WindowTitle>
<WindowActions>
<WindowAction Name="Close" OnClick="OnFormClosed"/>
</WindowActions>
</TelerikWindow>


@code{

public void VisibleChangedHandler(bool visible) 
{
IsVisible = visible; // set the window visibility
/* Do whatever you want */
}

Hope that will help.

I'm not sure if the VisibleChanged event is fired when the close button is pressed. If this happend, you could use OnFormClosed and VisibleChangedHandler simultaneously.

Hi all,

You are on the right path.

There are a couple of options here:

• Use the VisibleChanged event
• Use the action click event and add visibility changing logic in its code as it is now a custom action

Please test to see which one of the above will suit your app requirements best.
