Answer 1

Hello Sandeep,

  I am not sure I caught the problem. If there is any misunderstanding, please let me know. Thanks.

  Do the property of SelectedCells and SelectedIndex at DataGrid work for you?

  You can also ask at http://wpf.codeplex.com/Thread/List.aspx due to it is a pre-release Control.

  Thanks.

Answer 2

Yes, SelectedIndex works for me, it gives row index. But I am not sure how to get the column index of the SelectedCell.

Thanks,
Sandeep

Answer 3

int index = this.datagrid.SelectedCells[0].Column.DisplayIndex;

private void DataGrid1_MouseClick(object sender, MouseButtonEventArgs e)
        {
            DependencyObject dep = (DependencyObject)e.OriginalSource;

            //Stepping through the visual tree
            while ((dep != null) && !(dep is System.Windows.Controls.DataGridCell))
            {
                dep = VisualTreeHelper.GetParent(dep);
            }

            //Is the dep a cell or outside the bounds of Window1?
            if (dep == null | !(dep is System.Windows.Controls.DataGridCell))
            {
                return;
            }
            else
            {
                System.Windows.Controls.DataGridCell cell = new System.Windows.Controls.DataGridCell();
                cell = (System.Windows.Controls.DataGridCell)dep;
                while ((dep != null) && !(dep is DataGridRow))
                {
                    dep = VisualTreeHelper.GetParent(dep);
                }

                if (dep == null)
                {
                    return;
                }
                int colindex = cell.Column.DisplayIndex;  //this returns COLUMN INDEX
               
                DataGridRow row = dep as DataGridRow;
                System.Windows.Controls.DataGrid dataGrid = ItemsControl.ItemsControlFromItemContainer(row) as System.Windows.Controls.DataGrid;
                int rowindex = dataGrid.ItemContainerGenerator.IndexFromContainer(row); //this returns ROW INDEX
                object value = ExtractBoundValue(row, cell);
                TextBox1.Text = value.ToString(); //this returns cell value
            }
        }
