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:

XML

<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>

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

XML

<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>

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!

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:

XML

<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>

Bye, Thomas.
