我希望在单个aspx页面上有3个GridView,由单个DB查询提供(显示静态数据,无需操作),并基于10秒计时器刷新表。我有返回已排序的数据表的代码。我可以让它更新我的一个更新面板中的一个gridview,但其他两个不渲染。
代码为:
<%@ Page Title="Index" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Admin.aspx.cs" Inherits="Test.Admin" %>
<script runat="server" type="text/c#">
protected void Page_PreRender(object sender, EventArgs e)
{
Label1.Text = "Panel refreshed at: " + DateTime.Now.ToLongTimeString();
FullAccessSession.DataSource=GetStatus("FullAccess");
FullAccessSession.DataBind();
Label2.Text = "Panel refreshed at: " + DateTime.Now.ToLongTimeString();
LimitedAccessSession.DataSource=GetStatus("LimitedStatus");
LimitedAccessSession.DataBind();
Label3.Text = "Panel refreshed at: " + DateTime.Now.ToLongTimeString();
LogData.DataSource = GetLog() ;
LogData.DataBind();
}
protected void Timer1_Tick(object sender, EventArgs e)
{
Label1.Text = "Panel refreshed at: " + DateTime.Now.ToLongTimeString();
FullAccessSession.DataSource=GetStatus("FullAccess");
FullAccessSession.DataBind();
}
protected void Timer2_Tick(object sender, EventArgs e)
{
Label3.Text = "Panel refreshed at: " + DateTime.Now.ToLongTimeString();
LogData.DataSource = GetLog() ;
LogData.DataBind();
}
protected void Timer3_Tick(object sender, EventArgs e)
{
Label2.Text = "Panel refreshed at: " + DateTime.Now.ToLongTimeString();
LimitedAccessSession.DataSource=GetStatus("LimitedStatus");
LimitedAccessSession.DataBind();
}
</script>
<div class="row">
<div class="col-md-7">
<asp:UpdatePanel ID="UpdateFullAccessStatus" runat="server" UpdateMode="Always">
<ContentTemplate>
<!--<asp:Timer ID="Timer1" runat="server" Interval="10000" OnTick="Timer1_Tick">
</asp:Timer>-->
<asp:Label ID="Label7" runat="server" Font-Bold="True" Text="Full Access Logged In Users"></asp:Label>
<br />
<asp:Label ID="Label1" runat="server" Text="Panel not refreshed yet."></asp:Label>
<br />
<asp:GridView ID="FullAccessSession" runat="server">
</asp:GridView>
<br />
</ContentTemplate>
</asp:UpdatePanel>
<asp:UpdatePanel ID="UpdateLimitedAccessStatus" runat="server" UpdateMode="Always">
<ContentTemplate>
<!--<asp:Timer ID="Timer3" runat="server" Interval="10000" OnTick="Timer2_Tick">
</asp:Timer>-->
<asp:Label ID="Label4" runat="server" Font-Bold="True" Text="Limited Access Logged In Users"></asp:Label>
<br />
<asp:Label ID="Label2" runat="server" Text="Panel not refreshed yet."></asp:Label>
<br />
<asp:GridView ID="LimitedAccessSession" runat="server">
</asp:GridView>
<br />
</ContentTemplate>
</asp:UpdatePanel>
<asp:UpdatePanel ID="UpdateLog" runat="server" UpdateMode="Always">
<ContentTemplate>
<!--<asp:Timer ID="Timer2" runat="server" Interval="10000" OnTick="Timer2_Tick">
</asp:Timer>-->
<asp:Label ID="Label5" runat="server" Font-Bold="True" Text="General Log"></asp:Label>
<br />
<asp:Label ID="Label3" runat="server" Text="Panel not refreshed yet."></asp:Label>
<asp:GridView ID="LogData" runat="server">
</asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</div>
我不明白为什么我的一个更新面板会工作。正如您所看到的,我已经尝试使用PreRender函数以及(目前已注释掉的)计时器。标签正在使用当前时间更新,但仅显示一个gridview。
任何帮助都将不胜感激
谢谢
