我的要求是显示 DataList 如下

Header1      Header2          Header1      Header2           

1            Value 1            3          Value 3                        

2            Value 2            4          Value 4

但我无法重复数据列表的标题部分。我的数据列表的完整代码是

     <asp:DataList ID="datalstProfileCount" runat="server" RepeatColumns="2" RepeatDirection="Horizontal"
                        RepeatLayout="Table" ShowHeader="true" OnItemDataBound="datalstProfileCount_ItemDataBound">

添加 'If datalistName.Items.Count > 1' 代码示例： 

    <HeaderTemplate>
          <table>
              <tr><td>Header1</td><td>Header2</td></tr>
                 <%If (data_list_name.Items.Count() > 1) {%>
                   <tr><td>Header1</td><td>Header2</td></tr>
                 <%}%>
          </table>
    </HeaderTemplate>

Header 永远不会重复，将 Header HTML 作为 Item Template 的一部分。根据 .Net Controls 实现，页眉是列表的头，只会出现一次，然后是项目模板，它将根据数据源中存在的项目数重复，然后是页脚。

像这样的东西：

<asp:DataList ID="datalstProfileCount" runat="server" RepeatColumns="2" RepeatDirection="Horizontal"   RepeatLayout="Table" ShowHeader="true" OnItemDataBound="datalstProfileCount_ItemDataBound">
          <HeaderTemplate>         
          </HeaderTemplate>
          <ItemTemplate>
                    //Header Section
                    //Data 
          </ItemTemplate>
</asp:DataList>

如果您仍然有一些困惑，请与您在评论中提到的标题部分和数据部分分享您的整个数据列表，我将为您提供更新的代码..

                                </td>
                            </tr>
                            <tr>
                                <td style="font-size: 14px">
                                    Active Members Count:
                                </td>
                                <td style="padding-left: 10px">
                                    <asp:Label ID="lblMemberCount" runat="server" Text="" ForeColor="#C82124" Font-Size="14px"></asp:Label>
                                </td>
                            </tr>
            </table>
        </FooterTemplate>
</asp:DataList>

在服务器端添加以下代码：

protected void datalstProfileCount_ItemDataBound(Object sender, DataListItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    {
        if(e.Item.ItemIndex <=1)
        {
            var headerRow = (System.Web.UI.HtmlControls.HtmlTableRow)e.Item.FindControl("trHeader");
            if(headerRow != null)
            {
                headerRow.Style.Add(HtmlTextWriterStyle.Visibility, "");
            }
        }
    }
}

您可能需要对样式进行一些更改，但这也可以实现。
