在listview值asp.net C上更改表格行文本和bgcolor

Question

我有一个listview，我正在尝试根据＆＃34; callswaiting＆＃34;的值来更改文本颜色和背景颜色。这是用C＃编写的。

我正在努力实现这一目标：

  If(Eval("availableAgents") < 1); Then
; If(Eval("callsWaiting" > 2) ,Then );
{    
    tblSheet.Style.Add("color", "black");
    tblSheet.Style.Add("background-color", "red");
}
    Else;
{
    tblSheet.Style.Add("color", "black");
    tblSheet.Style.Add("background-color", "orange");
}
    End If;
Else;
{
    tblSheet.Style.Add("color", "white");
    tblSheet.Style.Add("background-color", "green");
}
    End If;

对如何将其更新为ASPX和C＃感到困惑。

我的ASPX代码是：

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <Triggers>
        <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
        </Triggers>            
        <ContentTemplate>
            <asp:ListView ID="ListView1" runat="server" DataSourceID="con_csq_agentDB" onitemdatabound="ListView1_ItemDataBound">
                     <AlternatingItemTemplate>
                        <tr id="MainTableRow" style="background-color: #ADADAD;">
                            <td style="background-color: gray; color: whitesmoke;">
                                 <asp:Label ID="csqnameLabel" runat="server" Text='<%# Eval("csqname") %>' />
                             </td>
                             <td>
                                 <asp:Label ID="callswaitingLabel" runat="server" Text='<%# Eval("callswaiting") %>' />
                             </td>
                             <td>
                                 <asp:Label ID="convoldestcontactLabel" runat="server" Text='<%# Eval("convoldestcontact") %>' />
                             </td>
                             <td>
                                 <asp:Label ID="loggedinagentsLabel" runat="server" Text='<%# Eval("loggedinagents") %>' />

                             <td>

                             <td>
                                 <asp:Label ID="availableagentsLabel" runat="server" Text='<%# Eval("availableagents") %>' />

                     </ItemTemplate>
                     <LayoutTemplate>
                        <table id="itemPlaceholderContainer" runat="server" data-height='100%'>
                            <tr runat="server" style="background-color: #113C77; color: #000000;">

                                         <tr id="itemPlaceholder" runat="server">

                                     </table>
                     </LayoutTemplate>

我的C＃代码是：

public partial class csq_agent : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
    ListView1.DataSourceID = con_csq_agentDB.UniqueID;

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

        cell.BgColor = "Red";
    }

}

}
