WPF样式触发器可以这样做吗？ [英] Can WPF Style Trigger do this?

问题描述

我的from中有一个datagrid，我使用DataTrigger来设置DataGridCell的前景色以确保它看起来很清晰，就像这样：

There''s a datagrid in my from,and I ues a DataTrigger to set the DataGridCell''s foreground color to ensure that it looks clear,just like this:

<Style TargetType="my:DataGridCell">
     <Style.Triggers>
          <DataTrigger Binding="{Binding Path=State}" Value="0">
               <Setter Property="Foreground" Value="Black" />
          </DataTrigger>
          <DataTrigger Binding="{Binding Path=State}" Value="1">
               <Setter Property="Foreground" Value="Green" />
          </DataTrigger>
     </Style.Triggers>
</Style>

然后我想设置它'' StyleTrigger，以确保它们具有相同的背景和BorderBrush，就像这样：

And then I want to set it''s StyleTrigger,to make sure they have same background and BorderBrush,just like this:

<Style.Triggers >
    <Trigger Property="IsSelected" Value="True">
        <Setter Property="Background" Value="#d4ecff"/>
        <Setter Property="BorderThickness" Value="0"></Setter>
        <Setter Property="BorderBrush" Value="#d4ecff"></Setter>
    </Trigger>
</Style.Triggers>

然后我有一个问题，当我选择一个单元格时，单元格前景改变白色因为我没有设置它所以它被设置为默认颜色。

我想实现这个目标：无论选择哪个单元格，单元格背景都会改变（＃d4ecff），但前景将是不改变：如果它是绿色，它保持绿色，如果它是黑色，它保持黑色。



我怎么能这样做？谢谢大家帮助我！

but then I have a question,when I selected one cell,the cell foreground change White because I didn''t set it so it been set a acquiescent color.
I want to achieve this:whichever cell i select,the cell background will change same(#d4ecff),but the foreground will not change:If it''s Green,it keeps Green and if it''s Black ,it keeps Black.

How Can I do this ? thank you everyone helps me!

推荐答案

我认为你可以使用MultiDataTrigger实现这一点对于 IsSelected 属性

（除 DataTrigger 之外状态属性）如下：

Hi,

I think you can achieve this using a MultiDataTrigger for the IsSelected property
(in addition to the DataTrigger for the State property) like so:

<MultiDataTrigger>
   <MultiDataTrigger.Conditions>
      <Condition Binding="{Binding Path=IsSelected}" Value="True" />
      <Condition Binding="{Binding Path=State}" Value="0" />
   </MultiDataTrigger.Conditions>
   <MultiDataTrigger.Setters>
      <Setter Property="Background" Value="#d4ecff" />
      <Setter Property="BorderThickness" Value="0" />
      <Setter Property="BorderBrush" Value="#d4ecff" />
      <Setter Property="Foreground" Value="Black" />
   </MultiDataTrigger.Setters>
</MultiDataTrigger>

<MultiDataTrigger>
   <MultiDataTrigger.Conditions>
      <Condition Binding="{Binding Path=IsSelected}" Value="True" />
      <Condition Binding="{Binding Path=State}" Value="1" />
   </MultiDataTrigger.Conditions>
   <MultiDataTrigger.Setters>
      <Setter Property="Background" Value="#d4ecff" />
      <Setter Property="BorderThickness" Value="0" />
      <Setter Property="BorderBrush" Value="#d4ecff" />
      <Setter Property="Foreground" Value="Green" />
   </MultiDataTrigger.Setters>
</MultiDataTrigger>

再见，托马斯。
