谢谢~~

自己顶下 请大家帮帮忙~~很多方法都试了，哎~~郁闷~~

你这显然是数据连接字符串有问题，你的AppSettings[]中一堆什么

[comtry]

应该不是它的错~那是编码问题，显示成那样子了。其他页面没事的，我还绑定DropDownList了，显然应该不是AppSettings[]的错。

("Êý¾Ý¿â"))

这是什么东东

[comtry]

昏~那是编码问题，就显示成这样子了~不是它的错~~~请帮忙看看别的地方有什么错~？我想是不是…………我也不知道，因为本地运行的很好，其他页面也行~
我想是数据库连接的事？？？~~其他页面都是绑定的DataGrid，运行没问题的。这些有问题的页面都是用的dataset.但是我不知道错误在哪儿啊~~贴点代码：
Dim conn As sqlConnection, da As sqlDataAdapter, ds As DataSet, sql As String
Dim comd As sqlCommand, dr As sqlDataReader
sql = "Select Count(*) From car"
conn = New sqlConnection(ConfigurationSettings.AppSettings("数据库"))
comd = New sqlCommand(sql, conn)
comd.Connection.Open()
dr = comd.ExecuteReader
If dr.Read Then AllRecord = dr(0)
dr.Close()
comd.Connection.Close()
comd.Dispose()

例如Web.Config中
<appSettings>
<add key="sqlconnstring" value="server=localhost;database=linpcontract;uid=sa;pwd=;" />
</appSettings>
调用
conn = New sqlConnection(ConfigurationSettings.AppSettings("sqlconnstring"))

[sjc0]

conn.open();

[comtry]

回 sjc0(流浪者)
conn.open();没用的，我试过~
调用也是没有问题的吧~~你看上面的代码~~

The ConnectionString property has not been initialized.]
System.Data.SqlClient.SqlConnection.Open() +433 错误的地方
感觉还是连接有问题，例如：server=localhost;database=linpcontract;uid=sa;pwd= 全部写对了？呵呵
奇怪了....

[comtry]

事情是：在其他页面是可以用的！我感觉也是数据库连接问题，但…………
