Set Focus / Selection to child item

Question

Hi All,

I have a TreeView control with several TreeViewItem objects. My TreeViewItem object consists of a DockPanel and my DockPanel consists of an Image object and a TextBlock object. Now what I basically want to do, is on the selection of the TreeViewItem, bubble the selection down to the TextBlock. So that my Image is not in a "selection" mode.

The reason for this is once I select my TreeViewItem, it selects my entire TreeViewItem giving my Image an ugly blue background colour which I would like to avoid if possible...

Alternatively, if someone could help me "override" the default selection style so I can set it transparent and force my TextBlock item to then have the "selection" background...

Kind Regards

try this

<TreeView.Resources>

<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}">Transparent</SolidColorBrush>

<SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}">Black</SolidColorBrush>

</TreeView.Resources>

Hi lee d,

How would I go about converting this to C#?

Sorry, but I'm building my treeview in code and all my resources etc. are located in my code.

Thanx for your effort!

Regards

Add the following to XAML file

<Style x:Key="noHighlight" TargetType="{x:Type TreeViewItem}">

<Style.Resources>

<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}">Transparent</SolidColorBrush>

<SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}">Black</SolidColorBrush>

 

</Style.Resources>

</Style>

and in the codebehind,  set the ItemContainerStyle

TreeView tv1;

tv1.ItemContainerStyle = this.FindResource("noHighlight") as Style;
