Question

我想就我的网站中有搜索功能提出建议。它将找到注册的客户，以便管理员更容易找到特定的客户。

您是否可以提供示例代码段以便我可以完成此特定搜索功能？

谢谢。

这是我的.aspx代码

  <asp:TextBox ID="txtSearch" runat="server" BorderStyle="Solid" Width="218px" 
        ontextchanged="txtSearch_TextChanged"></asp:TextBox>
&nbsp;<asp:Button ID="btnSearch" runat="server" Text="Search" />
</p>
<div style="overflow-x:auto; width:1200px">
 <asp:GridView ID="gvCustomer" runat="server" AutoGenerateColumns="False" 
        BackColor="#CCCCCC" BorderColor="#999999" BorderStyle="Solid" BorderWidth="3px" 
        Caption="Customer Profile" CellPadding="4" CellSpacing="2" DataSourceID="SqlDataSourceBM" 
        ForeColor="Black" onrowcommand="gvCustomer_RowCommand" 
        DataKeyNames="ApplicantUsername" >
        <Columns>
            <asp:BoundField DataField="Branch" HeaderText="Branch"

            <asp:BoundField DataField="NoALastName" HeaderText="Last Name" 
                SortExpression="NoALastName" />

        SelectCommand="SELECT [ApplicantUsername], [Branch], [NoALastName], [NoAFirstName] FROM [CustomerRegistration] WHERE (([Branch] = @Branch) AND ([NoALastName] LIKE '%' + @NoALastName + '%'))">
        <SelectParameters>
            <asp:SessionParameter Name="Branch" SessionField="ApplicantUsername" 
                Type="String" />

由于您未在此处提供任何代码并询问方向，因此请转到此处。假设您的TextBox名称为“textBox1”，旁边有一个按钮。在该按钮的单击事件中，您应该在数据库中查询与“textBox1”内的文本匹配的客户名称。您将用于搜索的查询类似于：

SELECT * FROM Customers
WHERE CustomerName LIKE "%" + textBox1.text + "%"; //Assuming the table name is Customers

这应该返回名称中包含textBox1.text的所有客户。希望这能让您了解从哪里开始。干杯,,
