How to cancel the AddNewRow operation using single Esc key from edit mode in WPF DataGrid (SfDataGrid)?

1 min read

You can cancel the editing operation when you press Esc Key in WPF DataGrid (SfDataGrid). The AddNewRow operation is cancelled when you pressed the Esc key twice while the AddNewRow cell is in editing mode.

Since when you press the Esc key in AddNewRow cell which is in edit mode below actions will happen,

1. At first key press, cell editing get canceled

2. At second key press AddNewRow operation is canceled.

On the other hand, you can cancel the AddNewRow operation in single Esc key by

override the GridSelectionController class and cancel the AddNewRow operation in HandleKeyDown event as like below code snippet.

C#

sfdatagrid.SelectionController = new GridSelectionControllerExt(sfdatagrid);
public class GridSelectionControllerExt : GridSelectionController
{
    public GridSelectionControllerExt(SfDataGrid sfdatagrid) : base(sfdatagrid)
    {
    }
    public override bool HandleKeyDown(KeyEventArgs args)
    {            
        if (args.Key == Key.Escape)
        {
            if (this.DataGrid.View.IsAddingNew)
            {
                if (this.CurrentCellManager.CurrentCell.IsEditing)
                    this.CurrentCellManager.EndEdit(true);
                this.DataGrid.GetAddNewRowController().CancelAddNew();
            }              
        }
        return base.HandleKeyDown(args);
    }
}
