start edit mode on failed validation
posted

i want to enter edit mode for a failed validation.  I don't understand why I can't get the grid to enter edit mode.  The validation is lighting up correctly and the cell has focus (dotted selection).  But edit mode is failing to start.

 

 

 

 

 

 

 

 

 

 

 

 

public void OnValidationFailed()
        {
            foreach (var currentCell in grdResults.RecordManager.Current.OfType<DataRecord>()
                .Where(record => record != null)
                .SelectMany(record => (from currentCell in record.Cells
                                       let cvp = CellValuePresenter.FromCell(currentCell)
                                       where cvp != null && cvp.HasDataError
                                       select currentCell)))
            {
                currentCell.IsActive = true;
                grdResults.ActiveCell = currentCell;
                grdResults.ExecuteCommand(DataPresenterCommands.StartEditMode);
                return;
            }
        }

    Hello,

     

    It has been a while since you have made your post, in case you still need support I will be glad to assist you further. I suppose the other community members can benefit from this answer as well. I have been looking through your post and I suggest you add the following code in the EditModeEnded event of the XamDataGrid:

    if (e.Cell.HasDataError) { Dispatcher.BeginInvoke(new Action(() => { e.Editor.StartEditMode(); }), DispatcherPriority.Background, null); } 

    


     
    
    In order to force the Cell to enter edit mode if the value didn’t pass validation.
    

     
    

    Feel free to write me if you have further questions.
