Calculate Sum (Total) Bootstrap Responsive GridView ASP.Net

Hi Shashikant, Thanks for you kinda response. We can Also Achieve it via Row Data bound.

<asp:TemplateField HeaderText="Salary" ItemStyle-HorizontalAlign="Right">
                            <ItemTemplate>
                                <asp:Label runat="server" ID="lblSalary" Text='<%#Eval("Salary")%>'></asp:Label>
                            </ItemTemplate>
                           <FooterTemplate>
                                <asp:Label runat="server" ID="lblTotalSalary"></asp:Label>
                            </FooterTemplate>
                        </asp:TemplateField>

TimeSpan? TotalSalary { get { return ViewState["TotalSalary"] as TimeSpan?; } set { ViewState["TotalSalary"] = value; } }

        protected void Page_Load(object sender, EventArgs e)
        {
            TotalSalary = new TimeSpan();
        }

protected void grdAttendance_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label lblSalary = e.Row.FindControl("lblSalary") as Label;
if (TotalSalary == TimeSpan.Zero)
{
TotalSalary = TimeSpan.Parse(lblSalary.Text);
}
else
{
TotalSalary += TimeSpan.Parse(lblSalary.Text);
}
}
if (e.Row.RowType == DataControlRowType.Footer)
{
 
Label lblTotalSalary = e.Row.FindControl("lblTotalSalary") as Label;
lblTotalSalary.Text = TotalSalary.Value.ToString();
}
}
