我有一个主WPF数据网格,其中包含两个网格上带有selectionchanged三角形的详细“子”数据网格
<DataGrid x:Name="RepertoiresDataGrid"
SelectionChanged="RepertoiresDataGrid_SelectionChanged">
..
..
<DataGrid.RowDetailsTemplate>
<DataTemplate>
<DataGrid x:Name="CommentsDataGrid"
CanUserAddRows="True"
CanUserDeleteRows="True"
CanUserSortColumns="True"
ItemsSource="{Binding Path=Comments}"
SelectionUnit="FullRow"
SelectionChanged="CommentsDataGrid_SelectionChanged">
..
..
支持代码
private void CommentsDataGrid_SelectionChanged(object sender,
SelectionChangedEventArgs e)
{
}
private void RepertoiresDataGrid_SelectionChanged(object sender,
SelectionChangedEventArgs e)
{
CommentsAsync(sender);
}
RepertoiresDataGrid_SelectionChanged按预期工作,因为它在RepertoiresDataGrid中更改选择时触发
CommentsDataGrid_SelectionChanged几乎按预期工作,因为它会在CommentsDataGrid中更改选择时触发,但在触发此选项后,也会触发RepertoiresDataGrid_SelectionChanged。
在处理CommentsDataGrid_SelectionChanged调用后是否可以停止事件链?
答案 0 :(得分:0)
添加e.Handled = true;到了
private void CommentsDataGrid_SelectionChanged(object sender,
SelectionChangedEventArgs e)
{
e.Handled = true;
}
这将停止事件链。
