Hello Stefan,

thanks for you support, i think  i have as beginner some easy wpf problems :(
But in my application i use datatemplates and then the parent of the Button is Null.

Hmmmm, can you help a beginner....

Here a little example where the parent is null, i hope you understand.

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525" xmlns:ig="http://schemas.infragistics.com/xaml">

    <Window.Resources>
        <DataTemplate x:Key="LargeTileView">
            <Button  Name="myTestButton" Content="{Binding Source}" Click="Button_Click"/>
        </DataTemplate>
    </Window.Resources>

    <Grid>
        <ig:XamTileManager
                Name="xamTileManager1"
                ItemTemplate="{StaticResource LargeTileView}"
            ItemsSource="{x:Static Fonts.SystemFontFamilies}">
        </ig:XamTileManager>
    </Grid>
</Window>

---- code behind

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            ((sender as Button).Parent as XamTile).IsMaximized = true;
        }

Hello,

Since you use ItemsSource I can suggest you change the Button’s Click event handler like this:

(((sender as Button).TemplatedParent as ContentPresenter).TemplatedParent as XamTile).IsMaximized = true;

Please let me know if this helps you or you need further assistance on this matter.

Hello Thomas,

I can suggest you set the ContentTemplate Property of the ContentPresenter, which is in the XamTile's Template, to {TemplateBinding ContentTemplateResolved}. This way the ItemTempalteMaximized and ItemTemplateMinimizedExpanded Properies will work correctly.

Hope this helps you.

Hello Stefan,

your solution doesn't work. Only the content will maximized. But it is the wrong content. The content should change to TemplateMaximized.
The button should be replaced with a Text "MytextBlock Maximized"

Thx for help

Thomas

Hello Thomas,

I have been looking into your code and I can suggest you replace the StackPanel used in the XamTile's Style Tempalte with Grid.

Hope this helps you.

Hello Stefan,

based on the previous problem a new problem is added.
In the sample Code I remove the header and build templates for the maximzed and minimizedExpanded view.
if I used the tilemanager with normal header everythinbgs works fine, but when i remove the header then the view will maximized but there content is always the same, it doesn't change to the template. Where is the Problem ? I think the style for xamTile WithoutHeader remove the contents or fixed it to the normal view.

        {

By the way, is it possible to change the itemcontainerstyle from one view to another? I think no, without reload the items the tiles can't change the header view.
I'd prefer the first view without the header and after maximized the view with header.
Any idea.

greetings

Thomas
