如何用不同的颜色设置数据网格中的每一行 [英] How to set each row in datagrid with a different color

问题描述

我有一个带有数据网格的日志窗口，每个条目都写入数据网格中的新行。

我要根据行的严重性来设置行颜色日志消息（例如致命异常=红色，信息=绿色）。

我该如何使用绑定或动态资源呢？

预先感谢！

解决方案

假设这不适用于Silverlight，则可以使用DataTriggers。 p>

假设严重程度从您的物品中暴露为财产...

 < Style TargetType = {x：Type工具箱：DataGridRow}> 
< Style.Triggers> 
< DataTrigger Binding = {绑定严重性} Value =高> 
< Setter Property = Background Value = Red /> 
< / DataTrigger> 
< DataTrigger Binding = {Binding Severity} Value = Medium> 
< Setter Property = Background Value = Yellow /> 
< / DataTrigger> 
< DataTrigger Binding = {绑定严重性} Value =低> 
< Setter Property = Background Value = Green /> 
< / DataTrigger> 
< /Style.Triggers> 
< / Style> 
  

对于Silverlight，您应该使用转换器...

 < Style TargetType = {x：Type工具箱：DataGridRow}> 
< Setter Property = Background 
 Value = {Binding Path = Severity，
 Converter = {StaticResource StatusToColorConveter}} /> 
< / Style> 
  

在StatusToColorConveter.Convert（）方法中...

  switch（value.toString（））
 {
 case High：返回Colors.Red; 
 case Medium：返回Colors.Yellow; 
 case Low：返回Colors.Green; 
} 
  

让我知道是否有帮助。

I have a log window with a datagrid, each entry write to new row in the datagrid.

I want to set the row color accordingly to the severity of the log message (e.g. fatal exception = Red , Information = Green).

How do i can do it with binding or dynamic resource?

Thanks in advance!

Assuming that this is not for Silverlight, you can use DataTriggers.

Assume Severity is exposed as a property from your items...

   <Style TargetType="{x:Type toolkit:DataGridRow}">
         <Style.Triggers>
             <DataTrigger Binding="{Binding Severity}" Value="High">
                  <Setter Property="Background" Value="Red"/>
             </DataTrigger> 
             <DataTrigger Binding="{Binding Severity}" Value="Medium">
                  <Setter Property="Background" Value="Yellow"/>
             </DataTrigger> 
             <DataTrigger Binding="{Binding Severity}" Value="Low">
                  <Setter Property="Background" Value="Green"/>
             </DataTrigger> 
         </Style.Triggers>
   </Style> 

For silverlight you should use converters...

   <Style TargetType="{x:Type toolkit:DataGridRow}">
        <Setter Property="Background"
                Value="{Binding Path=Severity,
                                Converter={StaticResource StatusToColorConveter}}"/>
   </Style>

In StatusToColorConveter.Convert() method ...

  switch(value.toString())
  {
      case "High": return Colors.Red;
      case "Medium": return Colors.Yellow;
      case "Low": return Colors.Green;
  }

Let me know if this helps.
