<DataGridComboBoxColumn.ElementStyle>

<EventSetter Event="GotFocus" Handler="b1SetColor"/>
</Style>

C#
C＃
void b1SetColor(object sender, RoutedEventArgs e)

}
But nothing happens (doesn't fire) when I do click the Combobox cell. is there a way I can achieve this?
但是当我单击 Combobox 单元格时，没有任何反应（不会触发）。有没有办法实现这一目标？

Use DataGridCellStyleand hook PreviewMouseDownevent.
使用DataGridCellStyle和钩子PreviewMouseDown事件。
<DataGrid>
<DataGrid.CellStyle>
<Style TargetType="DataGridCell">
<EventSetter Event="PreviewMouseDown" Handler="b1SetColor"/>
</Style>
</DataGrid.CellStyle>
</DataGrid>

On the level of DataGridyou can subscribe to SelectedCellsChangedevent:
在DataGrid您可以订阅SelectedCellsChanged事件的级别上：
XAML:
XAML：
<DataGrid SelectedCellsChanged="selectedCellsChanged"/>
C#:
C＃：
void selectedCellsChanged(object sender, SelectedCellsChangedEventArgs e)
{
MessageBox.Show("Clicked");
}
