不显示指定的值从SQL返回在Asp.net WebForm GridView

Question

我有一个asp.net应用程序有一个gridview的所有用户，但我不想'管理员'用户显示给用户。

HTML

<asp:GridView ID="tblUsers" runat="server" AutoGenerateColumns="False" CellPadding="4" DataSourceID="SqlUsers" GridLines="None" Width="15%"> 
     <AlternatingRowStyle BackColor="White" /> 
     <Columns> 
      <asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" /> 
     </Columns> 
     <HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" /> 
     <RowStyle BackColor="#EFF3FB" /> 
    </asp:GridView> 
    <asp:SqlDataSource ID="SqlUsers" runat="server" ConnectionString="<%$ ConnectionStrings:PaydayLunchConnectionString1 %>" SelectCommand="SELECT [Name] FROM [Users]"></asp:SqlDataSource> 

我没有后面的代码为这个在所有。我是否需要某种存储过程或某些广告，如果是这样，我如何编写它作为存储过程并不是我的强项。

Answer 1

你需要流向何方cluase添加到像SELECT [名]您的选择命令FROM [用户]其中，[名]！= '管理员' 或选择[名称] FROM [用户] Where [fieldname]！='Admin'。见下面的代码。

<asp:GridView ID="tblUsers" runat="server" AutoGenerateColumns="False" CellPadding="4" DataSourceID="SqlUsers" GridLines="None" Width="15%"> 
    <AlternatingRowStyle BackColor="White" /> 
    <Columns> 
     <asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" /> 
    </Columns> 
    <HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" /> 
    <RowStyle BackColor="#EFF3FB" /> 
</asp:GridView> 
<asp:SqlDataSource ID="SqlUsers" runat="server" ConnectionString="<%$ ConnectionStrings:PaydayLunchConnectionString1 %>" SelectCommand="SELECT [Name] FROM [Users] Where [name] != 'Admin'"></asp:SqlDataSource> 

Answer 2

只需在您的SelectCommand附加一个where子句。

HTML

<asp:GridView ID="tblUsers" runat="server" AutoGenerateColumns="False" CellPadding="4" DataSourceID="SqlUsers" GridLines="None" Width="15%"> 
     <AlternatingRowStyle BackColor="White" /> 
     <Columns> 
      <asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" /> 
     </Columns> 
     <HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" /> 
     <RowStyle BackColor="#EFF3FB" /> 
    </asp:GridView> 
    <asp:SqlDataSource 
     ID="SqlUsers" 
     runat="server" 
     ConnectionString="<%$ ConnectionStrings:PaydayLunchConnectionString1 %>" 
     SelectCommand="SELECT [Name] FROM [Users] WHERE [name] <> 'Admin'"></asp:SqlDataSource>
