Dynamic changing rowspan in GridView

Dynamic changing rowspan in GridView

Dynamic changing rowspan in GridView

(OP)
I am trying to add rowspans to the first 3 columns in my grid so that repeating values don't display.

I am starting with the 1st column of the grid.

What I am doing is saving the value of the cell when it changes and if it changes I save the new value and the cell of the row I want to change the rowspan to.

The problem is that when I change the value of the rowspan the row moves to the right and all the values are in the wrong columns. This sort of makes sense but I don't know how to solve it.

What I want to have happen is not move the value of the column at all into the grid if the rowspan is merging the row.

I am doing this in the RowDataBound event. Should it be done somewhere else?

CODE

public string PreviousDate { get; set; }
public int DateRowSpan { get; set; }

protected void gvShipPlan_RowDataBound(Object sender, GridViewRowEventArgs e)
{
    GridView gv = (GridView)sender;

    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        if (PreviousDate != e.Row.Cells[0].Text)
        {
            PreviousDate = e.Row.Cells[0].Text;
            DateRowSpan = e.Row.RowIndex;
        }
        else
        {
            //Increase the rowspan row count by one
            gv.Rows[DateRowSpan].Cells[0].RowSpan = gv.Rows[DateRowSpan].Cells[0].RowSpan + 2;
        }
    }
} 

Thanks,

Tom
