停止CTRL单击不影响父数据网格 [英] Stop CTRL-Click from affecting parent datagrid

问题描述

我有一个WPF DataGrid，在RowDetailsTemplate中声明了另一个数据网格；

I have a WPF DataGrid that has another datagrid declared within the RowDetailsTemplate;

<DataGrid name="dataGrid1" RowDetailsVisibilityMode="VisibleWhenSelected">
  ...
  <DataGrid.RowDetailsTemplate>
    <DataTemplate>
      <DataGrid name="dataGrid2">
        ...
      </DataGrid/>
    </DataTemplate>
  </DataGrid.RowDetailsTemplate>
</DataGrid>

当我CTRL-单击子DataGrid上的一行时，它将取消选择父DataGrid的 SelectedItem 并隐藏 RowDetailsTemplate 。

When I CTRL-Click a row on the child DataGrid, it un-selects the parent datagrid's SelectedItem and hides the RowDetailsTemplate.

我认为这是一些路由事件的行为，但我试图在数据网格上捕获 MouseDown / LeftButtonMouseDown ，但未触发任何事件。我还在子数据网格上捕获了 SelectedItemChanged 事件，并设置了 e.Handled = true; ，但该事件仍然存在

I assume this is some kind of Routed Event behaviour, but I've tried to catch MouseDown/LeftButtonMouseDown on the datagrid but no event is fired. I've also caught the SelectedItemChanged event on the child datagrid and set e.Handled = true; but the event still triggers on the parent.

当 CTRL -单击子DataGridRow时，如何阻止父datagrid取消选择？

How can I stop the parent datagrid from unselecting when CTRL-Clicking a child DataGridRow?

推荐答案

在子控件上捕获 PreviewMouseLeftButtonDown ，将 e.Handled = true 和 dataGridRow.IsSelected =！dataGridRow.IsSelected 修复了此问题。

Catching PreviewMouseLeftButtonDown at the child control, setting e.Handled = true and dataGridRow.IsSelected = !dataGridRow.IsSelected fixed this.
