在listview中水平平铺表格？

Question

我有来自数据库的记录，由部门分隔，我想在不同的表（每个部门）内水平地平铺它们。这是我尝试过的（这不起作用）

.aspx的

    <asp:ListView ID="lvUnderwriting" GroupItemCount="6" runat="server" GroupPlaceholderID="grpPlaceHolder1" ItemPlaceholderID="itemPlaceHolder1">
       <LayoutTemplate>
     <table>
          <asp:PlaceHolder ID="grpPlaceHolder1" runat="server" ></asp:PlaceHolder>
     </table>
          </LayoutTemplate>
          <GroupTemplate>
                 <span><b><%# Eval("gensubbusiclass") %></b></span>
           <table>
                     <tr>
                            <th>Role Name:</th>
                            <th>Pending Tasks:</th>
                            <th>On Leave:</th>
                    </tr>    
                    <tr>
                            <asp:PlaceHolder ID="itemPlaceHolder1" runat="server"></asp:PlaceHolder>
                    </tr>
                    </table>
                    </GroupTemplate>
                    <ItemTemplate>
                        <tr>
                            <td><span> <%#Eval("RoleName") %></span></td>
                            <td><span><%# Eval("Count") %></span></td>
                            <td><span><%# Eval("OnLeave") %></span></td>
                       </tr>
                   </ItemTemplate>
 </asp:ListView>

数据库行 我目前的结果。由于某种原因，第二部门分为两个表。另外我如何水平平铺它们？

Answer 1

好的，我得到的是ListView无法显示开箱即用的主要详细记录。这是我试图让它为我工作。诀窍是如果标题数据绑定项被更改，则动态地向表添加新行，数据库记录需要提前排序才能使其正常工作。从这里引用using Asp.net 3.5 ListView 4 Guys from Rolla

.aspx的

<asp:ListView ID="lvUnderwriting" runat="server" ItemPlaceholderID="itemPlaceHolder1">
        <LayoutTemplate>
            <table border="1" cellpadding="4px">
            <tr>
                <th>Role Name:</th>
                <th>Assigned:</th>
                <th>On Leave:</th>
            </tr>
            <tr>
                <asp:PlaceHolder ID="itemPlaceHolder1" runat="server" />
            </tr>
            </table>
        </LayoutTemplate>
        <ItemTemplate>
        <tr>
        <%# AddGroupUnderwriting() %>
            <td><%# Eval("RoleName") %></td>
            <td><%# Eval("Count") %></td>
            <td><%# Eval("OnLeave") %></td>               
        </tr>
        </ItemTemplate>
        </asp:ListView>

C＃

// Add group row to underwriting grid
private string prevUWBusinessClass = "";
public string AddGroupUnderwriting()
{
    string currentUWBusinessClass = Eval("gensubbusiclass").ToString();
    if (currentUWBusinessClass != prevUWBusinessClass)
    {
        prevUWBusinessClass = currentUWBusinessClass;
        return string.Format(@"<tr><td colspan=""3""><h3>Department: {0}</h3></td></tr>", currentUWBusinessClass);
    }
    else
        return "";
}
