如何在 RibbonButton.Click 上提高 DataGrid.LostFocus？

发布于 2024-10-11 08:04:07 字数 662 浏览 3 评论 0原文

以下代码使用 ToolBar 并正确导致 DataGrid.LostFocus（通过在执行命令之前提交任何未提交的行编辑）；

<Toolbar FocusManager.IsFocusScope="False">
  <Button Command="{Binding CommandName}" />
</ToolBar>
<DataGrid ... />

但是，我现在尝试使用 Ribbon（oct10 版本）执行相同的操作，但以下内容不会导致 DataGrid.LostFocus 引发；

<Ribbon>
  <RibbonTab>
    <RibbonGroup FocusManager.IsFocusScope="False">
      <RibbonButton Command="{Binding CommandName}" />
    </RibbonGroup>
  </RibbonTab>
</Ribbon>
<DataGrid ... />

如何使用功能区引发此事件？我尝试将 IsFocusScope 移动到其他级别（Ribbon、RibbonTab、RibbonButton），但无济于事。

原文

The following code uses a ToolBar and correctly causes DataGrid.LostFocus (there by committing any uncomitted row-edits before the command is executed);

<Toolbar FocusManager.IsFocusScope="False">
  <Button Command="{Binding CommandName}" />
</ToolBar>
<DataGrid ... />

However, I am now trying to do the same using the Ribbon (oct10 release), but the following does not cause DataGrid.LostFocus to be raised;

<Ribbon>
  <RibbonTab>
    <RibbonGroup FocusManager.IsFocusScope="False">
      <RibbonButton Command="{Binding CommandName}" />
    </RibbonGroup>
  </RibbonTab>
</Ribbon>
<DataGrid ... />

How can I raise this event using the Ribbon? I have tried moving the IsFocusScope through the other levels (Ribbon, RibbonTab, RibbonButton) to no avail.

不喜欢这个，因为需要后台代码，但没有任何其他答案；

<Ribbon>
  <RibbonTab>
    <RibbonGroup>
      <RibbonButton Command="{Binding CommandName}" Click="dropFocus" />
    </RibbonGroup>
  </RibbonTab>
</Ribbon>
<Control IsTabStop="False" Name="focusControl"/>
<DataGrid ... />

以及后面的代码；

private void dropFocus(object sender, RoutedEventArgs e)
{
  Keyboard.Focus(focusControl);
}

Don't like this due to the need for code behind, but in the absence of any other answers;

<Ribbon>
  <RibbonTab>
    <RibbonGroup>
      <RibbonButton Command="{Binding CommandName}" Click="dropFocus" />
    </RibbonGroup>
  </RibbonTab>
</Ribbon>
<Control IsTabStop="False" Name="focusControl"/>
<DataGrid ... />

And the code behind;

private void dropFocus(object sender, RoutedEventArgs e)
{
  Keyboard.Focus(focusControl);
}

虽然这个问题已经有6年多了，但我也想发布我的解决方案：
只需将 PreviewMouseDown 的事件处理程序添加到 RibbonWin 并将焦点设置为 null...

private void RibbonWin_PreviewMouseDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
    FocusManager.SetFocusedElement(this, null);
}

Altough this question is over 6 years old, I want to post my solution too:
Just add an Eventhandler for PreviewMouseDown to the RibbonWin and set the focus to null...

private void RibbonWin_PreviewMouseDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
    FocusManager.SetFocusedElement(this, null);
}
