问题 Do ControlTemplates in WPF require a TargetType? I am restyling some controls, and notice that the comboboxitem, listiviewitem and listboxitem all have the same template: <ControlTemplate x:Key="ListBoxItemCT" TargetType="{x:Type ListBoxItem}"> <Border x:Name="Bd" SnapsToDevicePixels="true" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Padding="{TemplateBinding Padding}" CornerRadius="1">

WPF/XAML: Set a style with a different TargetType?

问题 I have an external style resource in a resource dictionary I'm referencing with x:Key. It has an x:TargetType specifying a target (TextBlock). Is it possible to apply this to a control containing a TextBlock and have all TextBlock elements within that control have the style applied? Thanks, Robert 回答1: The easiest way to do that would be to define a Style within the Control that is based on your external style resource, but don't specify an x:Key, just the TargetType. <Style TargetType="{x

问题 This question already has answers here : Closed 6 years ago . Possible Duplicate: Difference between TargetType=“controlType” and TargetType=“{x:Type controlType}” when to use {x:Type …}? At Difference between TargetType="controlType" and TargetType="{x:Type controlType}" I can see that these different methods of setting type are basically the same. But I was wondering if there are any performance implications since I guess {x:Type} will instantiate a markup object. 回答1: I'd suggest that

问题 Is there any difference (or advantage) for use this statement: Style x:Key="{x:Type DataGridCell}" TargetType="{x:Type DataGridCell}" with omitting the x:Key attribute? I think WPF assigns the key to the same x:Type under the hood. 回答1: The MSDN documentation for Style.TargetType confirms your suspicions: Setting the TargetType property to the TextBlock type without setting an x:Key implicitly sets the x:Key to {x:Type TextBlock}. This also means that if you give the above Style an x:Key

问题 What is the difference between: <Style TargetType="{x:Type Border}"> and: <Style TargetType="Border"> When and why do I need to use the {x:Type …} ? 回答1: There is no difference in effect; in both cases the TargetType property will be set to typeof(Border) The first version {x:Type Border} was needed in the first version of WPF because the compiler did not use the TypeConverter class to convert the string into a Type object and you needed to specify the TypeExtension class to do that for you.

In WPF you can set the TargetType to either the name of the type or you can set it to {x:Type nameOfType} . Does anyone know what the difference is? Kent Boogaart Nothing. Since the property type is Type , the XAML parser knows to try and convert whatever you supply to a Type . In other scenarios, the property type might be less specific (eg. Object ), and that's where you need the markup extension, otherwise the XAML parser will just interpret your value as a String . Sorry for poking such an old thread, but I feel it's worth it. I have recently encountered a situation which shows that x:Type
