Question

我的Style和DataGridRow有一个DataGridCell。在我的RowStyle中，我更改了所选Row的背景，在我的CellStyle中，我更改了我的焦点Cell的背景。这在我第一次点击新的Row时有效。但是，如果我点击同一Cell中的另一个Row，则不会应用Style。如果我使用我的箭头键更改Cell它可以正常工作，而不是我点击鼠标。在我的DataGrid我SelectionMode =单身。

如果我在Trigger中定位'RowGridTop'，则会正确显示焦点Cell，但ZIndex不正确。 Here显示了我需要的原因额外的Grid。

Answer 1

好的，我做到了。我不得不更改ZIndex，以便DataGridRowStyle上的那些高于DataGridCellStyle上的那个。我还必须在我的“RowGrid”IsHitTestVisible="False"上设置Grid。

不显示“在行中聚焦单元格”
