在Asp.net WebForm GridView中不显示SQL返回的指定值

Question

我有一个asp.net应用程序，该应用程序具有所有用户的gridview ，但我不希望向用户显示“管理员”用户。

的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>

我根本没有任何代码。 我是否需要某种类型的存储过程或广告，如果是的话，我如何将其编写为存储过程不是我的强项。

Answer 1

您只需要在选择命令中添加位置字符串，例如SELECT [Name] FROM [Users] where [name]！='Admin'或SELECT [Name] FROM [Users] Where [fieldname]！='Admin'。 参见下面的代码。

<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中附加一个where子句即可。

的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>
