Have you tried by setting up the EditIndex property of the DataGrid?

Example:

Code behind

    protected void grdProducts_RowEditing(object sender, GridViewEditEventArgs e)
    {
        this.grdProducts.EditIndex = e.NewEditIndex;
        This.BindGrid();
    }

Note that you have to re-bind your grid

Usually you save the data per row, which means, you have an edit link in each row and after you enter edit mode, a save button and optionally a cancel button appear which will allow you to save the values of that specific row

Following this approach is trivial when using the GridView:

    protected void grdProducts_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        // old values for the current row
        var oldValues = e.OldValues;

        // new (updated) values for the current row
        var newvalues = e.NewValues;

        // Exit edit mode
        this.grdProducts.EditIndex = -1;

        // Update the grid
        this.BindGrid();
    }

In the grid markup just add the following:

    onrowupdating="grdProducts_RowUpdating"

If you need to specify custom controls when editing or when displaying the cell data in read-only mode, use grid templates:
