Totaling a column in Datgrid

[Atif Jalal]

Hi,
I would like to know if there is a way to print 'Sum' of all the
values of one of the columns in a datagrid in an ASP.net application
using vb.net. The Sum should be displayed all the way at the end below
the column values.

Like:
___________________________
Column1 Column2 Column3
___________________________
XX
YY
ZZ
--
SUM AA
--

one way to do this would be to forget the datagrid, but rather look at the
source...
if the source is a table, for example, you could easily enumerate through
the rows at that column, and tally up the value, then create a new row which
has a column for that total.
if the source isn't a table, convert it to one and make the table the data
source.

hope that helps.
Dan.

One approach is to insert the subtotal into the footer row of the datagrid
in the itemdatabound routine.

if(e.itemtype == listitemtype.footer)
string strCol = columname;
e.item.cells[0].Columnspan = 2;
e.item.cells[0].Text = "Sum";
e.item.cells[0].BackColor= Color.LimeGreen;
e.item.cells[1].Text =
ds.Tables[0].Compute("Sum(["+strCol+"])",String.Empty));
