Datagrid question

[MSNEWS]

Hi

I have a datagrid with 8 Columns, columns called Monday - Sunday, and a
column called TOTAL. The Monday - Sunday columns are template columns with
a textbox inside. The TOTAL column is a label column.

When the user enteres numbers into the Monday - Sunday columns I want TOTAL
to add up all the columns on the current row.

I guess this needs to be done with client side vbscript? But I have no clue
where to start.

Also could somebody give me hints on how to validate by Monday - Sunday
columns so that they can only enter numbers between 0 and 24.

Thanks

Hi

I have a datagrid with 8 Columns, columns called Monday - Sunday, and a
column called TOTAL. The Monday - Sunday columns are template columns
with
a textbox inside. The TOTAL column is a label column.

When the user enteres numbers into the Monday - Sunday columns I want
TOTAL
to add up all the columns on the current row.

I guess this needs to be done with client side vbscript? But I have no
clue
where to start.

Also could somebody give me hints on how to validate by Monday - Sunday
columns so that they can only enter numbers between 0 and 24.

Thanks
