c# gridview 更新功能问题
我想添加1个功能，能在原来的查询后的基础上，对部门这个字段可以实现修改功能，能在我现有的代码基础上添加，给出前后太代码最好，谢谢前台代码：<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<form id="form1" runat="server">
<div>
<asp:Label ID="Label1" runat="server" Text="请选择查询条件"></asp:Label>
<asp:DropDownList ID="DropDownList1" runat="server">
<asp:ListItem Value="name">姓名</asp:ListItem>
<asp:ListItem Value="no">工号</asp:ListItem>
</asp:DropDownList>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="确定" onclick="Button1_Click"
style="height: 26px" />
<br />
<asp:Label
ID="Label2" runat="server"></asp:Label>
<br />
<br />
</div>
<asp:GridView ID="GridView1" runat="server" Height="132px" Width="307px">
</asp:GridView>
</form>
</body>
</html>

string sqlstr;
SqlConnection con = new SqlConnection("Data Source=.;Initial Catalog=EMPDATA;Integrated Security=True");
con.Open();
if (DropDownList1.Text == "name")
{
sqlstr = "select Emp_Name as 姓名,Emp_No as 工号,Emp_department as 部门,Emp_Tel as 电话 from guest where Emp_Name like '%" + TextBox1.Text + "%'";
}
else
{
sqlstr = "select Emp_Name as 姓名,Emp_No as 工号,Emp_department as 部门,Emp_Tel as 电话 from guest where Emp_No like '%" + TextBox1.Text + "%'";
}
SqlDataAdapter mySA = new SqlDataAdapter(sqlstr,con);
DataSet ds = new DataSet();
mySA.Fill(ds,"ss");
GridView1.DataSource = ds;
GridView1.DataBind();
if (GridView1.Rows.Count == 0)
{
Label2.Text = "无符合数据";
}
else {
Label2.Text = " ";
}
}
}
