Hello,

I am trying to customize my RadTileViewItem header using one of your ResourceDictionary, I downloaded from one of your examples in the forums. It worked nicely and I am able to change the color and effects in the header.

But the issue is, on clicking the maximize button in header it does nothing except changing the icon to minimize. I was expecting it to actually maximize the item. I am guessing that I need to stick some code to make that happen but where to write that code is my confusion.

Can you please suggest anything,

Thanks,
Deepak

P.S: Apologies for sticking a long code but it doesn't allow me to attach a XAML/zip file.

Hello Deepak,

Please make sure that you keep the Command property of the Maximize ToggleButton when copy-paste the default control template as it does the logic for maximization of TileView Items in code:

<telerik:RadToggleButton x:Name="MaximizeToggleButton"

HorizontalAlignment="Right"

VerticalAlignment="Center"

Style="{StaticResource maximizeToggleStyle}"

Command="{x:Static Telerik_Windows_Controls_TileView:TileViewCommands.ToggleTileState}"/>

The same is applicable if you customize the Minimize Button as well, just the Command x:Static property is different (you may see the original one under the control template that we ship).
