Question

您好我想显示每列7到18的每一列总数。使用此代码，它为我提供了所有列的总数，并在页脚的每个单元格中显示它。我想在相应的页脚单元格中显示每个列的总数。我在asp中使用asp：BoundFields。

示例：column1 sum = 2，column2 sum = 3，column3 sum = 4，这个代码给了我相同的总数2 + 3 + 4 = 9到页脚的所有单元格。我想在页脚中显示.cell [1] = 2，footer.cell [2] = 3，footer.cell [4] = 4（以编程方式）。每列的总数而不是所有列的总数。
有什么建议吗？

private int TotalStats = (int)0;
 protected void GridViewHomeTeamStats_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        for (int i = 7; i <= 18; i++){
        // check row type
        if (e.Row.RowType == DataControlRowType.DataRow)
            // if row type is DataRow, add ...                
        {
            TotalStats += Convert.ToInt32(e.Row.Cells[i].Text);
        }
        else if (e.Row.RowType == DataControlRowType.Footer)
            // If row type is footer, show calculated total value
            e.Row.Cells[i].Text = String.Format("{0:0.##}", TotalStats);
            }
    }

谢谢。你能用这三列帮助我吗？在这些列中，值类似于：3 / 4,5 / 6等。我想在等效的页脚单元格中显示此列的总和和除。示例，如果列有2行，值为1 / 2,2 / 4我想在页脚单元格中显示1 + 2/2 + 4 = 0.5 = 50％。这是来自同一GridViewHomeTeamStats的asp代码：

 <asp:GridView ID="GridViewHomeTeamStats" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSourceHomeTeam" ShowFooter="True" OnRowDataBound="GridViewHomeTeamStats_RowDataBound">
    <Columns>            
        <asp:TemplateField HeaderText="FT" SortExpression="FREE_THROW_MADE">
            <ItemTemplate>
                <asp:Label ID="Label1" runat="server" Text='<%# Eval("FREE_THROW_MADE") + "/" + Eval("FREE_THROW_ATTEMPT") %>'></asp:Label></ItemTemplate>
        </asp:TemplateField>
        <asp:TemplateField HeaderText="2P" SortExpression="2POINTS_MADE">
            <ItemTemplate>
                <asp:Label ID="Label2" runat="server" Text='<%# Eval("2POINTS_MADE") + "/" + Eval("2POINTS_ATTEMPT") %>'></asp:Label>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:TemplateField HeaderText="3P" SortExpression="3POINT_MADE">
            <ItemTemplate>
                <asp:Label ID="Label3" runat="server" Text='<%# Eval("3POINT_MADE") + "/" + Eval("3POINT_ATTEMPT") %>'></asp:Label>
            </ItemTemplate>
        </asp:TemplateField>

试试这个（可能我宁愿使用小数）：

int[] TotalStats = new int[12] { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0};

protected void GridViewHomeTeamStats_RowDataBound(object sender, GridViewRowEventArgs e)
{
    for (int i = 7; i <= 18; i++)
    {
        // check row type
        if (e.Row.RowType == DataControlRowType.DataRow)
        // if row type is DataRow, add ...                
        {
            TotalStats[i-7] += Convert.ToInt32(e.Row.Cells[i].Text);
        }
        else if (e.Row.RowType == DataControlRowType.Footer)
            // If row type is footer, show calculated total value
            e.Row.Cells[i].Text = String.Format("{0:0.##}", TotalStats[i-7]);
    }
}
