Question

我使用以下语法来操作gridview的RowDataBound和RowCreated方法，以便每次更改employeeid以添加总行。对我来说非常基本，这很好。好吧，我现在需要更进一步，在页脚中添加所有总行的SUM。

我怎样才能做到这一点？以下是每次更改employeeid时我用来添加总计的内容：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            GridView1.Columns[14].Visible = false;
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                employeeid = Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "employeeid").ToString());
                decimal tmpfield1 = Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "field1").ToString());
                decimal tmpfield2 = Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "field2").ToString());
                decimal tmpfield3= Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "field3").ToString());
                decimal tmpfield4 = Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "field4”).ToString());
                decimal tmpfield5 = Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "field5").ToString());
                decimal tmpfield6 = Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "field6").ToString());
                qtyfield1 += tmpfield1;
                qtyfield2 += tmpfield2;
                qtyfield3 += tmpfield3
                qtyfield4+= tmpfield4;
                qtyfield5+= tmpfield5;
                qtyfield6 += tmpfield6;
            }
        }
        protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
        {
            bool newRow = false;
            if ((employeeid > 0) && (DataBinder.Eval(e.Row.DataItem, "employeeid") != null))
            {
                if (employeeid != Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "employeeid").ToString()))
                    newRow = true;
            }
            if ((employeeid > 0) && (DataBinder.Eval(e.Row.DataItem, "employeeid") == null))
            {
                newRow = true;
                rowIndex = 0;
            }
            if (newRow)
            {
                wh = “11”;
                GridView GridView1 = (GridView)sender;
                GridViewRow NewTotalRow = new GridViewRow(0, 0, DataControlRowType.DataRow, DataControlRowState.Insert);
                NewTotalRow.Font.Bold = true;
                NewTotalRow.BackColor = System.Drawing.Color.Gray;
                NewTotalRow.ForeColor = System.Drawing.Color.White;
                TableCell HeaderCell = new TableCell();
                HeaderCell.Text = "Total";
                HeaderCell.HorizontalAlign = HorizontalAlign.Left;
                HeaderCell.ColumnSpan = 4;
                NewTotalRow.Cells.Add(HeaderCell);
                HeaderCell = new TableCell();
                HeaderCell.HorizontalAlign = HorizontalAlign.Right;
                HeaderCell.Text = qtyfield1.ToString();
                NewTotalRow.Cells.Add(HeaderCell);
                HeaderCell = new TableCell();
                HeaderCell.HorizontalAlign = HorizontalAlign.Right;
                HeaderCell.Text = qtyfield2.ToString();
                NewTotalRow.Cells.Add(HeaderCell);
                HeaderCell = new TableCell();
                HeaderCell.HorizontalAlign = HorizontalAlign.Right;
                HeaderCell.Text = qtyfield3.ToString();
                NewTotalRow.Cells.Add(HeaderCell);
                HeaderCell = new TableCell();
                HeaderCell.HorizontalAlign = HorizontalAlign.Center;
                HeaderCell.Text = qtyfield4.ToString();
                NewTotalRow.Cells.Add(HeaderCell);
                HeaderCell = new TableCell();
                HeaderCell.HorizontalAlign = HorizontalAlign.Center;
                HeaderCell.Text = qtyfield5.ToString();
                NewTotalRow.Cells.Add(HeaderCell);
                HeaderCell = new TableCell();
                HeaderCell.HorizontalAlign = HorizontalAlign.Center;
                decimal grandtotalfield6
                try { grandtotalfield6 = Convert.ToDecimal(qtyfield6) / Convert.ToDecimal(wh); }
                catch { grandtotalfield6 = 0.00M; }
                HeaderCell.Text = grandtotalfield6.ToString("P", CultureInfo.InvariantCulture);
                NewTotalRow.Cells.Add(HeaderCell);
                HeaderCell = new TableCell();
                HeaderCell.HorizontalAlign = HorizontalAlign.Right;
                HeaderCell.Text = "";
                HeaderCell.ColumnSpan = 4;
                NewTotalRow.Cells.Add(HeaderCell);
                GridView1.Controls[0].Controls.AddAt(e.Row.RowIndex + rowIndex, NewTotalRow);
                rowIndex++;
                qtyTotal = 0;
                qtyfield1 = 0;
                qtyfield2 = 0;
                qtyfield3 = 0;
                qtyfield4 = 0;
                qtyfield5 = 0;
                qtyfield6 = 0;
            }
        }

修改
经过进一步的思考和分析，我认为我可以通过这样做来捕获总数，但是我怎么能把它转过来并且能够将这些信息写入页脚？

sumf1 += qtyfield1;
sumf2 += qtyfield2;
sumf3 += qtyfield3;
sumf4 += qtyfield4;
sumf5 += qtyfield5;
sumf6 += qtyfield6;

Answer 1

为什么不使用GridView1.Rows.Count选项？

GridView1.FooterRow.Cells[2].Text = Convert.ToString(GridView1.Rows.Count);

如果我理解你很好，他会从x行开始＆＃34;将这个数量保存在隐藏的字段中＆＃34;

然后每次添加一行时从总行中减去它，结果将是为该人员添加的总行数，然后将该值设置为页脚单元格

Answer 2

你快到了。在您的RowDataBound代码中添加支票，以确定您是在查看DataRow还是Footer如何做到这一点就是这样（当然为所有数量添加）你想要显示，但应该是一个快速的文本更改，因为语法将保持不变）

这是你背后的C＃代码

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
           //Process like you do in your method
        }
        if (e.Row.RowType == DataControlRowType.Footer)
        {
            Label lblSum1 = (Label)e.Row.FindControl("lblTotalqty");
            lblSum1.Text = Sum1.ToString();
        }
    }

修改您的HTML以添加到footertemplate并填充如此

<FooterTemplate>
  <div style="text-align: right;">
    <asp:Label ID="lblSum1" runat="server" />
  </div>
</FooterTemplate>

将总计添加到网格视图的页脚
