堅持在asp.net基於數據庫條目在列表視圖中的運行時間更改每行顏色

Question

我想基於存儲在數據庫中的數據更改列表視圖中每行的顏色。 我已經寫了下面的代碼，但我不通過這些幫助，我的對象可以訪問標記列表視圖的財產知道：

protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e) 
    { 
     if(e.Item.ItemType == ListViewItemType.DataItem) 
     { 
      ListViewDataItem dataitem = (ListViewDataItem)e.Item; 
      int policyid = (int)DataBinder.Eval(dataitem.DataItem, "policyID"); 
      if(policyid == 3) 
      //what should I write here to change the corresponding row's color? 

     } 


    } 

問候。

嘿王牌大賤諜這裏是代碼

ASPX CODE：

<asp:ListView ID="ListView1" runat="server" 
      onitemdatabound="ListView1_ItemDataBound"> 
      <LayoutTemplate> 
       <table id="itemPlaceholderContainer" border="0" cellpadding="0" cellspacing="0"> 
        <tr> 
         <th> 
          EmpID 
         </th> 
         <th> 
          EmpName 
         </th> 
         <th> 
          Department 
         </th> 
         <th> 
          Age 
         </th> 
         <th> 
          Address 
         </th> 
        </tr> 
        <tr runat="server" id="itemPlaceholder"> 
        </tr> 
       </table> 
      </LayoutTemplate> 
      <ItemTemplate> 
       <tr id="MainTableRow" runat="server"> 
        <td id="EmpID" runat="server"> 
         <asp:Label ID="EmpIDLabel" runat="server" Text='<%# Eval("EmpID") %>' /> 
        </td> 
        <td id="EmpNameTD" runat="server"> 
         <asp:Label ID="EmpNameLabel" runat="server" Text='<%# Eval("EmpName") %>' /> 
        </td> 
        <td id="DepartmentTD" runat="server"> 
         <asp:Label ID="DepartmentLabel" runat="server" Text='<%# Eval("Department") %>' /> 
        </td> 
        <td id="AgeTD" runat="server"> 
         <asp:Label ID="AgeLabel" runat="server" Text='<%# Eval("Age") %>' /> 
        </td> 
        <td id="AddressTD" runat="server"> 
         <asp:Label ID="AddressLabel" runat="server" Text='<%# Eval("Address") %>' /> 
        </td> 
       </tr> 
      </ItemTemplate> 
     </asp:ListView> 

，這裏是代碼隱藏代碼

protected void Page_Load(object sender, EventArgs e) 
    { 
     var Employee = new { EmpID = 1, EmpName = "Rahul Jain", Department = "IT", Age = 33, Address = "Hello" }; 
     var customerList = (new[] { Employee }).ToList(); 

     customerList.Add(new { EmpID = 2, EmpName = "Rahul Jain", Department = "IT", Age = 33, Address = "Hello" }); 
     customerList.Add(new { EmpID = 3, EmpName = "Rahul Jain", Department = "IT", Age = 33, Address = "Hello" }); 
     customerList.Add(new { EmpID = 4, EmpName = "Rahul Jain", Department = "IT", Age = 33, Address = "Hello" }); 
     customerList.Add(new { EmpID = 5, EmpName = "Rahul Jain", Department = "IT", Age = 33, Address = "Hello" }); 
     customerList.Add(new { EmpID = 6, EmpName = "Rahul Jain", Department = "IT", Age = 33, Address = "Hello" }); 

     customerList.Add(new { EmpID = 7, EmpName = "Rahul Jain", Department = "IT", Age = 33, Address = "Hello" }); 
     customerList.Add(new { EmpID = 8, EmpName = "Rahul Jain", Department = "IT", Age = 33, Address = "Hello" }); 
     customerList.Add(new { EmpID = 9, EmpName = "Rahul Jain", Department = "IT", Age = 33, Address = "Hello" }); 
     customerList.Add(new { EmpID = 10, EmpName = "Rahul Jain", Department = "IT", Age = 33, Address = "Hello" }); 


     ListView1.DataSource = customerList; 
     ListView1.DataBind(); 
    } 

    protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e) 
    { 
     if (e.Item.ItemType == ListViewItemType.DataItem) 
     { 
      ListViewDataItem dataitem = (ListViewDataItem)e.Item; 
      int policyid = (int)DataBinder.Eval(dataitem.DataItem, "EmpID"); 
      if (policyid == 3) 
      { 
       HtmlTableRow cell = (HtmlTableRow)e.Item.FindControl("MainTableRow"); 

       cell.BgColor = "Red"; 
      } 
     } 
    }
