在ASP SqlDataSource中定义ConnectionString [英] Defining ConnectionString in asp SqlDataSource

问题描述

我有我在 web.comfig 中的< appSettings> 下定义的数据库连接:

I have my database connectivity which I define under <appSettings> in web.comfig:

<appSettings>
    <add key="ConnStr" 
         value="Data Source=dsk-159\SQLEXPRESS;Initial Catalog=master;Integrated Security=True"/>
</appSettings>

但是问题是我无法像这样尝试从我的aspx页面访问它

But the problem is that I am unable to access it from my aspx page as I am trying like this

<asp:SqlDataSource ID="SqlDataSource2" runat="server" 
     ConnectionString="<%$ ConnectionStrings:goldsConnectionString %>"
     SelectCommand="SELECT distinct TechnologyId , [TechnologyName], [ChildId] FROM [TreeTable] where childid is null AND technologyid in(@hid1)">
     <SelectParameters>
         <asp:ControlParameter ControlID="hid1" Name="hid1" DefaultValue="23" />
     </SelectParameters>

代替< connectionStrings> 我想在< appSettings>

Plesae告诉正确的语法.

Plesae tell the correct syntax.

推荐答案

您的web.config应该如下所示:

Your web.config should be like below:

<appSettings>
<add key="ConnStr" value="Server=yourservername;Database=yourdatabasename;UID=yourusername;Password=youruserpassword"/>
</appSettings>

您的.aspx文件应如下所示:

And your .aspx file should like following:

<asp:GridView ID="grd" runat="server" DataSourceID="SqlDataSource2">
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ appSettings:ConnStr %>" SelectCommand="SELECT * FROM ticketmaster"></asp:SqlDataSource>
