在WPF的DataGrid中對行添加單擊事件

在做的一個c#的項目中發現Datagrid沒辦法直接對鼠標單擊進行響應，調用MouseDown事件也需要點擊某一行第二次才能響應。所以借助EventSetter來簡單的實現了一個。

界面部分的代碼

        <DataGrid x:Name="dataGrid" HorizontalAlignment="Left" Margin="10,38,0,0" VerticalAlignment="Top" Height="257" FontSize="13.333" AutoGenerateColumns="False" AlternationCount="2" CanUserAddRows="False" MinWidth="504" Width="513" SelectionUnit="FullRow"> <DataGrid.RowStyle> <Style TargetType="DataGridRow"> <EventSetter Event="GotFocus" Handler="Item_GotFocus"/> </Style> </DataGrid.RowStyle> <DataGrid.Columns> <DataGridCheckBoxColumn /> <DataGridTextColumn Header="歌曲名" Width="200" Binding="{Binding Path=Title}" IsReadOnly="True"/> <DataGridTextColumn Header="藝術家" Width="127" Binding="{Binding Path=Artist}" IsReadOnly="True"/> <DataGridTextColumn Header="專輯" Width="140" Binding="{Binding Path=Album}" IsReadOnly="True"/> </DataGrid.Columns> </DataGrid>

對應的c#的代碼

        private void Item_GotFocus(object sender, RoutedEventArgs e) { var item = (DataGridRow)sender; FrameworkElement objElement = dataGrid.Columns[0].GetCellContent(item); if (objElement != null) { CheckBox objChk = (CheckBox)objElement; objChk.IsChecked = !objChk.IsChecked; } }

附上用mousedown事件的代碼

        private void DataGrid_MouseDown(object sender, MouseButtonEventArgs e) { if (e.LeftButton == MouseButtonState.Pressed) { var se = dataGrid.SelectedItem; FrameworkElement objElement = dataGrid.Columns[0].GetCellContent(se); if (objElement != null) { CheckBox objChk = (CheckBox)objElement; objChk.IsChecked = !objChk.IsChecked; } } }

需要在這個界面的構造函數中添加

 dataGrid.MouseDown += DataGrid_MouseDown;
