Calculate total for each row in gridview

suchitra says:Its not like that.. But it is hard to explain it to some people

But use postbacks for each textbox you will be too expensive.

I have written an article on same with live demo. check out

http://www.aspsnippets.com/Articles/Calculate-Row-Total-and-Grand-Total-in-ASPNet-GridView-using-jQuery.aspx

Vinz code is good without using javascript at textchanged event.. But i want it at row command event

Since i have not used JQuery anytime

You have not used jQuery that's fine. But each time if you postback the server will be heavily affected.

BTW what you want on RowDataBound

 <asp:GridView ID="GVItem" runat="server" AutoGenerateColumns="False" 
                                    CssClass="GridItemStyle" Height="15px" ShowFooter="True"

                                    onrowdatabound="GVItem_RowDataBound" onrowcommand="GVItem_RowCommand"
