            <EventSetter Event="CheckBox.Checked" Handler="OnChecked"/>

Answer 1

您的 XAML 工作正常，问题在于您是否获得了复选框。您应该能够从使用未选中或已选中事件触发的复选框访问元素。

示例：

var ch = sender as Checkbox;
var row = data_kala.ItemContainerGenerator.ContainerFromItem(ch) as DataGridRow;
bool ischecked = ch.IsChecked;

if (ischecked) {
    row.BackGround = Brushes.Gray;
}
else {
    row.BackGround = Brushes.White;
}
