Working with Resources in WPF_问答_开发者_运维开发者技术经验分享

I am wanting to use the example from

http://blogs.microsoft.co.il/blogs/tomershamam/archive/2008/09/22/lt-howto-gt-replace-listview-columns-with-rows-lt-howto-gt.aspx

However I don't want to put this into the App.xaml code as this will apply to ALL gridviews, how do I apply this example to a select few gridviews in the application? The Resources look like this

<Style x:Key="{x:Static GridView.GridViewScrollViewerStyleKey}"
       TargetType="{x:Type ScrollViewer}">
        <Setter Property="Focusable"
            Value="false"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ScrollViewer}">
                    <Grid Background="{TemplateBinding Background}"
                      SnapsToDevicePixels="true">

                            <ColumnDefinition Width="Auto"/>

                            <RowDefinition Height="Auto"/>

I have tried creating a usercontrol and sticking that lot in the UserControl.Resources section but it didn't work, I can only get this example to work if i put them into the Application.Resources section which i obviously don't want. Help!! :-)

I think there's an error in your code.

I just copied it to use in a test project and got an error:

StaticResource reference 'GridViewColumnHeaderGripper' was not found.

on:

<Style TargetType="{x:Type GridViewColumnHeader}">

However I don't want to put this into the App.xaml code as this will apply to ALL gridviews, how do I apply this example to a select few gridviews in the application?

Just change the key of the style to be something other than GridView.GridViewScrollViewerStyleKey. Choose a custom key, and set the style explicity on controls that need it (using {StaticResource styleKey})
