问题描述

在我的gridview内，列定义如下

inside my gridview the columns are defined as follows

<asp:TemplateField HeaderText="Amount" HeaderStyle-Width ="100px" FooterStyle-HorizontalAlign="right">
<ItemTemplate><%# Eval("amount")%></ItemTemplate>
</asp:TemplateField>

我想获取我正在使用for循环的gridview中所有行的总数.
但是我无法使用findcontrol获取金额列的值.

i want to get the total amount of all rows in my gridview for which i am using a for loop.
but i am unable to get the value of my amount column using findcontrol.

推荐答案

试试以下

Hi,

Try the following

decimal priceTotal = 0;
void detailsGridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
          priceTotal += Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, _
          "amount"));
    }
    else if (e.Row.RowType == DataControlRowType.Footer)
    {
        e.Row.Cells[0].Text = "Totals:";
        // for the Footer, display the running totals
        e.Row.Cells[1].Text = priceTotal.ToString("c");
    }
}

希望这会有所帮助....

嗨
尝试使用ItemTemplate内的标签绑定您的金额

Hi
Try binding your amount using a label inside your ItemTemplate

<asp:TemplateField HeaderText="Amount" HeaderStyle-Width="100px" FooterStyle-HorizontalAlign="right">
               <ItemTemplate>
               <asp:Label ID="lblAmount" runat="server" Text='<%# Eval("Amount")%>'></asp:Label></ItemTemplate>
                              </asp:TemplateField>

然后在按钮上单击

And on button click

protected void btnTotal_Click(object sender, EventArgs e)
       {
           foreach (GridViewRow row in yourGridID.Rows)
           {
               Total+=double.Parse(((Label)row.FindControl("lblAmount")).Text);
           }

           yourLabelID.Text = Total.ToString();
       }

希望这会有所帮助....
