WpfToolkit的DataGrid：高亮修改的行 [英] WpfToolkit DataGrid: Highlight modified rows

问题描述

有没有一种方法，以突出显示所有在DataGrid中修改的行？由于网格绑定到 System.Data.DataTable 我想我也许可以每行的颜色绑定到它的RowState（下面的例子），但是那并不是' ：T似乎工作

任何想法

的xmlns：数据=CLR - 命名空间：System.Data这;装配= System.Data这

 <风格X：关键=DataGridRowStyle的TargetType ={X：类型工具箱：DataGridRow}> 
< Style.Triggers> 
<触发属性=IsSelectedVALUE =真正的> 
< setter属性=背景VALUE =蓝/> 
< /触发> 
< D​​ataTrigger绑定={结合的RowState}VALUE ={X：静态数据：DataRowState.Modified}> 
< setter属性=背景VALUE =浅黄/> 
< / DataTrigger> 
< /Style.Triggers> 
< /样式和GT; 
  

解决方案

 < DataGrid.RowStyle> 
<风格的TargetType =DataGridRow> 
< Style.Triggers> 
< D​​ataTrigger绑定={结合的RowState}VALUE ={X：静态数据：DataRowState.Modified}> 
< setter属性=背景VALUE =浅黄/> 
< / DataTrigger> 
< /Style.Triggers> 
< /样式和GT; 
< /DataGrid.RowStyle> 
  

更新结果
你还公布后您的XAML中，很明显，这个问题是不是在XAML中找到。我已经很快看了MSDN的数据表类，我不能看到让WPF检测的RowState - 特性的变化的机制。因此，直接绑定到这个属性不会给你可靠的结果。结果
看来你要包装你的数据项。我建议做一个视图模型的项目，并补充说，如果说该行已与变更通知（ INotifyPropertyChanged的或DP）更改的属性并绑定到该属性。肯定会有还其他的替代品，但国际海事组织创建每个项目一个VM是在大多数情况下，最好的解决方案。

Is there a way to highlight all the modified rows on a DataGrid? Since the grid is bound to a System.Data.DataTable I figured I might be able to bind the colour of each row to it's RowState (example below), but that doesn't seem to work.

Any ideas?

xmlns:data="clr-namespace:System.Data;assembly=System.Data"

<Style x:Key="DataGridRowStyle" TargetType="{x:Type toolkit:DataGridRow}">
    <Style.Triggers>
        <Trigger Property="IsSelected" Value="true">
            <Setter Property="Background" Value="Blue" />
        </Trigger>
        <DataTrigger Binding="{Binding RowState}" Value="{x:Static data:DataRowState.Modified}">
            <Setter Property="Background" Value="LightYellow" />
        </DataTrigger>
    </Style.Triggers>
</Style>

解决方案

<DataGrid.RowStyle> 
  <Style TargetType="DataGridRow"> 
    <Style.Triggers> 
        <DataTrigger Binding="{Binding RowState}" Value="{x:Static data:DataRowState.Modified}"> 
            <Setter Property="Background" Value="LightYellow" />            
        </DataTrigger> 
    </Style.Triggers> 
  </Style> 
</DataGrid.RowStyle> 

Update
After you have posted also your xaml, it's obvious that the problem is not to be found in the xaml. I have shortly looked at msdn for the DataTable-class and I can not see a mechanism that let WPF detect changes of the RowState-property. Therefore, direct binding to this property will not give you reliable results.
It seems that you have to wrap your data items. I recommend to make a ViewModel for the items and add a property that says if the row has changed with change notification (INotifyPropertyChanged or DP) and bind to this property. Surely there will be also other alternatives, but IMO creating a VM per item is in most cases the best solution.
