Question

在我的Asp.net应用中，我有一个GridView，我自己使用代码生成column[6]的数据。

通过查看下面的代码，我的footer有一个gridview。如果我使用页脚，问题是列[6]的文本将不会出现。如果我删除了footertext代码，那么我的第[6]栏的文本就出现了。问题是什么？两个代码都不能使用togather？我已经设置了ShowFooter =“True”

protected void Page_Load(object sender, EventArgs e)
{
    for (int i = 0; i < (this.GridView1.Rows.Count); i++)
    {
       this.GridView1.Rows[i].Cells[6].Text = "testing";
       //GridView1.Columns[1].FooterText ="footer 1";
    }
}

            AutoGenerateColumns="False" DataKeyNames="ID" CellPadding="4" 
            ForeColor="#333333" GridLines="None" ShowFooter="True" 
                    onrowdatabound="GridView1_RowDataBound">
            <RowStyle BackColor="#EFF3FB" />
            <Columns>
                <asp:BoundField DataField="reportDate" HeaderText="Report Date" dataformatstring="{0:dd MMMM yyyy}" SortExpression="reportDate" />

        </asp:GridView>

Answer 1

示例代码：以编程方式设置页脚文本

    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
      if (e.Row.RowType == DataControlRowType.Footer)
      {
         Label lbl = (Label)e.Row.FindControl("lblTotal");
         lbl.Text = grdTotal.ToString("c");
      }
   }

更新后的代码：

  decimal sumFooterValue = 0;
  protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {

        if (e.Row.RowType == DataControlRowType.DataRow)
        {
         string sponsorBonus = ((Label)e.Row.FindControl("Label2")).Text;
         string pairingBonus = ((Label)e.Row.FindControl("Label3")).Text;
         string staticBonus = ((Label)e.Row.FindControl("Label4")).Text;
         string leftBonus = ((Label)e.Row.FindControl("Label5")).Text;
         string rightBonus = ((Label)e.Row.FindControl("Label6")).Text;
         decimal totalvalue = Convert.ToDecimal(sponsorBonus) + Convert.ToDecimal(pairingBonus) + Convert.ToDecimal(staticBonus) + Convert.ToDecimal(leftBonus) + Convert.ToDecimal(rightBonus);
         e.Row.Cells[6].Text = totalvalue.ToString();
         sumFooterValue += totalvalue; 
        }

    if (e.Row.RowType == DataControlRowType.Footer)
        {
           Label lbl = (Label)e.Row.FindControl("lblTotal");
           lbl.Text = sumFooterValue.ToString();
        }

   }

protected void gvBill_RowDataBound(object sender, GridViewRowEventArgs e)
    {

        if (e.Row.RowType == DataControlRowType.DataRow)

            Total += Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "InvMstAmount"));
        else if (e.Row.RowType == DataControlRowType.Footer)

            e.Row.Cells[7].Text = String.Format("{0:0}", "<b>" + Total + "</b>");

Answer 5

/*This code will use gridview sum inside data list*/
SumOFdata(grd_DataDetail);

  private void SumOFEPFWages(GridView grd)
    {
        Label lbl_TotAmt = (Label)grd.FooterRow.FindControl("lblTotGrossW");
        /*Sum of the total Amount of the day*/
