我有具有 SelectionUnit = FullRow 的数据网格。当我在单元格上单击时,如果我按 Escape 键,它将进入编辑模式并且没有更新。它从编辑模式出来,但仍然有焦点(虚线)
但是如果我更新数据然后按 Escape 键,它基本上使用(CellEditEnding 事件)提交数据,然后当我尝试从代码中将焦点设置到该单元格时,它不起作用,整个数据网格失去焦点。
请参阅下面的代码。
//更新数据后按Escape时提交编辑代码
void DataGrid_CellEditEnding(object sender, DataGridCellEditEndingEventArgs e)
{
if (!_isManualEditCommit)
{
_isManualEditCommit = true;
DataGrid grid = (DataGrid)sender;
grid.CommitEdit(DataGridEditingUnit.Row, true);
isManualEditCommit = false;
}
}
void RhinoDataGrid_Loaded(object sender, RoutedEventArgs e)
{
RoutedEventHandler CellFocusedChangedHandler = new RoutedEventHandler(FocusChangedHandler);
AddHandler(DataGridCell.GotKeyboardFocusEvent, CellFocusedChangedHandler);
}
// Setting focus back to cell after updating data using Escape key
private void FocusChangedHandler(object sender, RoutedEventArgs args)
{
if (args.RoutedEvent.RoutingStrategy == RoutingStrategy.Bubble)
{
FrameworkElement DataGridCellObj = args.OriginalSource as FrameworkElement;
if (Keyboard.IsKeyDown(Key.Escape))
{
if (DataGridCellObj != null)
{
DataGridCell dgCell = DataGridCellObj as DataGridCell;
if (dgCell != null && !dgCell.IsEditing && !dgCell.IsReadOnly)
{
if (!dgCell.IsFocused)
{
dgCell.Focus();
}
DataGridRow dr = VisualTreeHelpers.FindVisualParent<DataGridRow>(dgCell);
int rIndex = ((DataView)this.ItemsSource).Table.Rows.IndexOf(((DataRowView)(dr.Item)).Row);
DataGridCellInfo dgCellInfo = new DataGridCellInfo(this.Items[rIndex], dgCell.Column);
if (dgCellInfo != null)
{
FocusManager.SetIsFocusScope(dgCell, true);
FocusManager.SetFocusedElement(dgCell, dgCell);
dgCell.BorderThickness = new Thickness(7);
}
}
}
}
}
请帮助谢谢
