Solution

{
    try
    {
        if (e.Key == Key.Enter)
        {
            e.Handled = true;
            var cell = GetCell(dgIssuance, dgIssuance.Items.Count - 1, 2);
            if (cell != null)
            {
                cell.IsSelected = true;
                cell.Focus();
                dg.BeginEdit();
            }
        }
    }
    catch (Exception ex)
    {
        MessageBox(ex.Message, "Error", MessageType.Error);
    }
}  

public static DataGridCell GetCell(DataGrid dg, int row, int column)
{
    var rowContainer = GetRow(dg, row);

    if (rowContainer != null)
    {
        var presenter = GetVisualChild<DataGridCellsPresenter>(rowContainer);
        if (presenter != null)
        {
            // try to get the cell but it may possibly be virtualized
            var cell = (DataGridCell)presenter.ItemContainerGenerator.ContainerFromIndex(column);
            if (cell == null)
            {
                // now try to bring into view and retreive the cell
                dg.ScrollIntoView(rowContainer, dg.Columns[column]);
                cell = (DataGridCell)presenter.ItemContainerGenerator.ContainerFromIndex(column);
            }
            return cell;
        }
    }
    return null;
}

Problem

I want to have a Custom DataGrid which can, - Move to next cell when Enter key is pressed also if it is in edit mode. - When the last column in the current row is reach, the focus should move to the first cell of next row. - On reaching to next cell, if the cell is editable, it should automatically became editable. - If the cell contains an `ComboBox` not comboboxcolumn, the combobox should DropDownOpen. Please help me in this. I have been trying from the past few day by creating a Custom DataGrid and wrote some code in ``` protected override void OnPreviewKeyDown(System.Windows.Input.KeyEventArgs e) ``` But I failed.
