在我的 Asp.net 应用程序中，我有一个 GridView 并且我自己使用代码生成了 column[6] 的数据。
通过查看下面的代码，我的 gridview 有一个 footer。问题是如果我使用页脚，我的 column[6] 文本将不会出现。
如果我删除页脚文本代码，则会出现我的列 [6] 文本。问题是什么？这两个代码不能一起使用吗？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";
}
}
.aspx
<asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1"
AutoGenerateColumns="False" DataKeyNames="ID" CellPadding="4"
ForeColor="#333333" GridLines="None" ShowFooter="True"

<RowStyle BackColor="#EFF3FB" />
<Columns>
<asp:BoundField DataField="reportDate" HeaderText="Report Date" dataformatstring="{0:dd MMMM yyyy}" SortExpression="reportDate" />
<asp:BoundField DataField="sponsorBonus" HeaderText="Sponsor Bonus" dataformatstring="{0:0.00}" SortExpression="sponsorBonus" HtmlEncode="False" />

<asp:BoundField HeaderText="Total" SortExpression="total" >
<ItemStyle Width="100px" />
</asp:BoundField>
</Columns>
<FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />

</asp:GridView>
最佳答案
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();
}
}

关于c# - 在 GridView 的页脚中显示总计，并在最后一列中添加列的总和(行虎钳)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11734308/
