Here is another one, which can show you the list of users online[^].
创建类似这样的网格，并在文件夹中提供两个绿色和红色按钮
CREATE A GRID LIKE THIS AND GIVE TWO BUTTONS GREEN AND RED IN A FOLDER
img ...................
< asp:gridview id ="dgvUsers" runat ="server" pagesize ="5" width ="158px" autogeneratecolumns ="False" xmlns:asp =#unknown">
DataKeyNames =状态" OnRowDataBound ="dgvUsers_RowDataBound" GridLines =无"
ShowHeader ="False">
<列> < asp:templatefield>
< itemtemplate>
< asp:image id ="imgGreen" runat ="server" height ="16px" imageurl =〜/Img/green.jpg">
宽度="16px"/>
< asp:image id ="imgRed" runat ="server" height ="16px" imageurl =〜/Img/red.jpg">
宽度="16px"/>
< itemstyle horizontalalign ="Center">
< asp:boundfield datafield ="USERNAME"标头text ="USERNAME"/>
< asp:boundfield datafield =状态" headertext =状态" visible ="False"/>
< emptydatatemplate>
< asp:image id ="Image1" runat ="server" imageurl =〜/Img/green.jpg"/>
使用计时器将网格与数据库中的数据表绑定.
< asp:timer id ="tmrUser" ontick ="tmrUser_Tick" runat ="server" interval ="30000" xmlns:asp =#unknown">
在计时器滴答事件中调用databind函数.并更改间隔以更改刷新时间...我建议将网格放在更新面板中....
希望这会起作用... !!!!!!!!!!!!!
img...................
<asp:gridview id="dgvUsers" runat="server" pagesize="5" width="158px" autogeneratecolumns="False" xmlns:asp="#unknown">
DataKeyNames="status" OnRowDataBound="dgvUsers_RowDataBound" GridLines="None"
ShowHeader="False">
<columns> <asp:templatefield>
<itemtemplate>
<asp:image id="imgGreen" runat="server" height="16px" imageurl="~/Img/green.jpg">
Width="16px" />
<asp:image id="imgRed" runat="server" height="16px" imageurl="~/Img/red.jpg">
Width="16px" />
<itemstyle horizontalalign="Center">
<asp:boundfield datafield="USERNAME" headertext="USERNAME" />
<asp:boundfield datafield="Status" headertext="Status" visible="False" />
<emptydatatemplate>
<asp:image id="Image1" runat="server" imageurl="~/Img/green.jpg" />
use a timer to bind the grid with the datatable from the database.
<asp:timer id="tmrUser" ontick="tmrUser_Tick" runat="server" interval="30000" xmlns:asp="#unknown">
call the databind function in timer tick event.. and change the interval to change refresh time...I suggest to put the grid in an update pannel.....
HOPE this will Work...!!!!!!!!!!!!!
