Merge Datagrids

Asked by: cdfllc

Hi, I have two datagrids on a page:

System.Web.UI.WebControls.DataGrid myGrid;
System.Web.UI.WebControls.DataGrid myGrid2;

myGrid2 Will always have a single row in it - how can I "copy" this row into myGrid in the code?

thanks!

<asp:datagrid id="totalsDataGrid" runat="server" HeaderStyle-CssClass="Normal " HeaderStyle-Font-Bold="true"
                        ItemStyle-CssClass="Normal " AutoGenerateColumns="False" CellPadding="5" Border="1" Width="100%"
                        EnableViewState="False" BorderColor="Gray" AlternatingItemStyle-BackColor="#cccccc" HeaderStyle-BackColor="#cccccc">
                        <ItemStyle CssClass="Normal "></ItemStyle>

                              <asp:BoundColumn DataField="2001" SortExpression="2001"></asp:BoundColumn>
                              <asp:BoundColumn DataField="2002" SortExpression="2002"></asp:BoundColumn>

                        </Columns>
                  </asp:datagrid>



They are just "normal" databound columns.


Maddog - If I understand you correctly, I don't think I want to do this.
My problem is this:

I want to be able to sort on the columns (by year for example 2000)
But I have another row of data that totals up each column - and I don't want to include this in the sorting.

That is the only reason that I  have the second datagrid - I couldn't figure out how to create the SQL to not sort that last row (the totals)
But now when the data is exported to Excel, I want to just do this, as I have done in the past:
                        myGrid.RenderControl(htmlWrite);
                  Response.Write(stringWrite.ToString());
                  Response.End();

So before I do this, I thought that I would just add that row into the other datagrid, and the user would never know the difference...

Thanks for the help. I found this code through maddog's link to help me:
I just had to convert the Function to c#

Sample code:

               {
                        myDataGrid.DataSource      = myDataTable;
                  myDataGrid.DataBind();

                  Response.Write(ConvertDtToTDF(myDataTable));
                  Response.End();
            }


            private String ConvertDtToTDF(DataTable dt)
            {
                  StringBuilder sb = new StringBuilder();
                  DataRow dr = dt.NewRow();
                  Object[] ary ;
                  int i = 0;
                  int iCol = 0;

                  //Output Column Headers
                  for (iCol=0; iCol < dt.Columns.Count; iCol ++)
                  {
                        sb.Append(dt.Columns[iCol].ToString() + "\t");
                  }
                  sb.Append("\r\n");

                  //Output Data
                  foreach (DataRow r in dt.Rows)
                  {
                        ary = r.ItemArray;
                              for (i=0; i < ary.Length; i++)
                              {
                                    sb.Append(ary[i].ToString() + "\t");
                              }
                        sb.Append("\r\n");
                  }

                  return sb.ToString();
            }
