Check this solution.

C#

DataGridRow row = myDataGrid.ItemContainerGenerator.ContainerFromIndex
                (myDataGrid.SelectedIndex) as DataGridRow;
 var i = 0; /// Specify your column index here.
 ////EDIT
 TextBox ele = ((ContentPresenter)(myDataGrid.Columns[i].GetCellContent(row))).Content as TextBox;
