ContextMenu

Question

üzerindeki simge boşluğunu kaldır Listede bir ContextMenu bağladım. Simgenin bulunduğu alanı kaldırmak istiyorum. Bu kolay bir şekilde mümkün mü?

    <ListBox.ContextMenu> 
        <ContextMenu > 
         <MenuItem x:Name="check" Header="Check all" Click="CheckAll" /> 
         <MenuItem x:Name="uncheck" Header="Uncheck all" Click="UnCheckAll" /> 
        </ContextMenu> 
       </ListBox.ContextMenu> 

Answer 1

MenuItem stilini ve denetim şablonunu değiştirmeniz gerekir. Aslında 4 farklı MenuItem rolü için 4 kontrol şablonunu yeniden tanımlamanız gerekiyor. Bu, ihtiyaçlarınız için değiştirmeniz gereken bir başlangıç ​​noktası kodudur. Pencere kaynaklarına veya başka bir uygun yere yerleştirin.
