Hi!

I need to implementation auto start begin edit cell in the same row and next column, after click in previous column.
In begin my table, code works correctly. But in the last row and in penultimate column code doesn't work correctly, it begin start edit in the last row and in third column.
But after how I write value by myself, code start to work correctly. I use telerik framework.
Thank you for your responses!

var element = sender as FrameworkElement;
        ConditionsRadGridView.CommitEdit();
        var parentCell = element.GetVisualParent<GridViewCell>();
        if (parentCell != null)
        {
            var index = ConditionsRadGridView.Columns.IndexOf(parentCell.Column);
            if (index != -1 && index < parentCell.ParentRow.Cells.Count)
            {
                var nextCell = parentCell.ParentRow.Cells[index] as GridViewCell;
                if (nextCell != null)
                {
                    ConditionsRadGridView.CurrentCellInfo = new GridViewCellInfo(nextCell);
                    ConditionsRadGridView.BeginEdit();
                }
            }
        }

Hello Nikita,

Can you tell me where the code that calls the BeginEdit() (the first code snippet) is executed? On what event and who calls it? Also, can you send me some drawings of a video that describes what is the expected behavior. I am asking this because I am not sure that I understand properly your requirement.

Regards,
Martin Ivanov
