How to change the border on a listboxitem while using a predefined template
- by djerry
Hey,
I'm using one of the defined wpf themes for my application, so all my controls automatically are pimped according to that theme.
Now i am filling a listbox with items (usercontrols), but not all of them should be visible at all time. But when i'm setting height to 0 (of usercontrol) or setting to invisible, i get a thick grey border of the listboxitems.
Can someone help me override the border of the listboxitem or show me where in the template i need to change the border, cause i just can't find it.
This is the part of the template for the listboxitem:
<Style d:IsControlPart="True" TargetType="{x:Type ListBoxItem}">
<Setter Property="SnapsToDevicePixels" Value="true"/>
<Setter Property="OverridesDefaultStyle" Value="false"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBoxItem}">
<ControlTemplate.Resources>
