[转]silverlight Datagrid 行上增加ToolTip

有两种办法：

1. 直接在后台处理
在数据绑定后 ，注册LoadingRow 事件
this.DataGrid.LoadingRow += new EventHandler<DataGridRowEventArgs>(DataGrid_LoadingRow);

void DataGrid_LoadingRow(object sender, DataGridRowEventArgs e)
{

      Task ts = e.Row.DataContext as Task;

      ToolTipService.SetToolTip(e.Row, ts.Name);

      //throw new NotImplementedException();
}

2. 稍微麻烦点， 重写datagrid row 模板， 
在微软msdn 上能找到 行模板，找到

<Storyboard>
<DoubleAnimation Storyboard.TargetName="BackgroundRectangle" Storyboard.TargetProperty="Opacity" Duration="0" To="0"/>
 </Storyboard>
在后面加上
<Storyboard> 
<DoubleAnimation Storyboard.TargetName="BackgroundRectangle" Storyboard.TargetProperty="Opacity" Duration="0" To="0" ToolTipService.ToolTip="{Binding Name}"/> 
 </Storyboard>
