如何确定wpf datagrid单元格是否处于编辑模式？

There are two scenarios:

有两种情况：

You select a row and press delete key to delete row.

您选择一行并按删除键删除行。
You select a cell and when its text is highlighted you press delete key to delete text.

您选择一个单元格，当其文本突出显示时，按删除键删除文本。

How do I distinguish between the two? in both cases I catch PreviewKeyPress and the Key is Delete Key, selected row is same.

我如何区分这两者？在这两种情况下我都会捕获PreviewKeyPress并且Key是Delete Key，所选行是相同的。

2 个解决方案

#1

For identifying the source of keypress, capture e.OriginalSource in the PreviewKeyPress(..) and check whether a cast to DataGridRow or DatagridCell is successful.

要识别keypress的来源，请在PreviewKeyPress（..）中捕获e.OriginalSource，并检查对DataGridRow或DatagridCell的强制转换是否成功。

DataGrid has the IsReadOnly property.

DataGrid具有IsReadOnly属性。

#2

Check the selected DataGridCell's IsEditing property, perhaps? I assume that, if you've selected a whole row, there will either be no selected cell, or IsEditing will be false on the selected cells (since I don't believe you can edit cells when multiple are selected).

或许，检查所选的DataGridCell的IsEditing属性？我假设，如果你选择了一整行，那么将不会选择任何单元格，或者所选单元格上的IsEditing将为false（因为我不相信你可以选择多个时编辑单元格）。

This approach may not work if, when you select a row, it automatically selects, say, the cell in the first column and puts it in editing mode... But I can't test that at the moment.

如果在选择一行时，它会自动选择第一列中的单元格并将其置于编辑模式，这种方法可能无法正常工作......但我现在无法测试。
