C# 如何应用RowStyle
我有一个数据网格,我想在它上有一个自定义的行样式。我创造了这种风格:C# 如何应用RowStyle,c#,.net,wpf,xaml,datagrid,C#,.net,Wpf,Xaml,Datagrid,我有一个数据网格,我想在它上有一个自定义的行样式。我创造了这种风格: <Style TargetType="{x:Type DataGridRow}" x:Key="styRow"> <Style.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter Property="Background" Value="LightG
<Style
TargetType="{x:Type DataGridRow}"
x:Key="styRow">
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Background" Value="LightGray" />
</Trigger>
</Style.Triggers>
</Style>
但该样式未应用于选定行。为什么?行样式实际上正在应用,但单元格样式正在覆盖它。因此,可以使单元格样式的背景色透明或与行样式相同。试试这个: 编辑3:这是默认的单元格样式,如果不执行任何操作,将应用该样式。注意
IsSelected
属性触发器将Background
设置为SystemColors。HighlightBrushKey
:
这是因为在您尚未编辑的行的模板中,有一个触发器可以更改背景。Mishka,我认为DataGrid没有行模板。我的意思是在行的样式中,有一个模板的setter。在它的值ControlTemplate中,有一个触发器可以改变它的背景。@SezMe:有用吗?我想是的,但我还在解决这个问题。在你的方法中,我觉得styRow没有用。对吗?当您将样式应用于整行而不是逐个单元格时,它确实有用。请参阅编辑1、编辑2和编辑3。感谢您提供的非常完整且有指导意义的答复。
