利用Silverlight DataGrid LoadingRow事件传入参数DataGridRowEventArgs
我们可以获取到Row对象She之其背景。
下面是一个简单示例
C# :

}
List<SourceModel> gridSources = new List<SourceModel>();
private void UserControl_Loaded(object sender, RoutedEventArgs e)
{
}
private void LoadSource(int n)
{
if (n < 1)
throw new Exception("should >=1");
gridSources.Clear();
for (int i = 0; i < n; i++)
{
gridSources.Add(new SourceModel() { ID = i.ToString(), Name = "test" + i, Group = ((int)(new Random().NextDouble() * i)).ToString() });
}
int j = 0;
gridSources = gridSources.OrderBy(t => t.Group).ToList();
gridSources.GroupBy(t => t.Group).ToList().ForEach(t =>
{
t.ToList().ForEach(k => k.BG = brushs[j % brushs.Length]);
j++;
});
}
