ResourceDictionary Style Error: "type must derive from FrameworkElement or FrameworkContentElement
resourcedictionary, wpf, xaml
Solution
Yes that means exactly what you said. GridViewColumn has no style. Its not an UiElement. However GridViewColumnHeader is one and it supports style.
Problem
GridViewColumnHeader inherits FrameworkElement but GridViewColumn doesn't. Does that mean we cannot style the latter in a resource dictionary? Snippet in Text ``` <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Style TargetType="{x:Type GridViewColumn}"> </Style> <Style TargetType="{x:Type GridViewColumnHeader}"> <Setter Property="Background" Value="LightBlue"/> </Style> </ResourceDictionary> ``` Snippet with Error Message
