datagrid中的觸發器

Question

我對此WPF-xaml代碼有疑問。沒有使用XAML很多，但設法得到我想要的這個代碼。但我覺得這根本不是好習慣。首先，我想根據某個單元格中的某些值將行從紅色更改爲綠色或灰色。我是否真的必須爲每個細胞保留一個觸發器，或者無論如何都要在整行上執行相同的觸發器？我也想設置一個特定的顏色，當選擇了行，但風格似乎並不支持「IsSelected」 ......

我不是很有經驗的DataGrid，所以這可能不是是最好的選擇，但我認爲你可以實現你的造型的行，而不是單獨的列後是什麼：

<DataGrid <!-- Your settings here -->> 
     <!-- Your column definitions here --> 
     <DataGrid.RowStyle> 
      <Style TargetType="DataGridRow"> 
       <Style.Triggers> 
        <DataTrigger Binding="{Binding Path=Errorcode}" Value="0"> 
         <Setter Property="Background" Value="LightGreen" /> 
         <!-- Other Setters --> 
        </DataTrigger> 
        <DataTrigger Binding="{Binding Path=Filename}" Value="File not created"> 
         <Setter Property="Background" Value="LightGray" /> 
        </DataTrigger> 

        <!-- Other Triggers --> 
        <Trigger Property="IsSelected" Value="True"> 
         <Setter Property="Background" Value="Red" /> 
         <!-- Other Setters --> 
        </Trigger> 
       </Style.Triggers> 
      </Style> 
     </DataGrid.RowStyle> 
    </DataGrid> 

好運。
