C＃Gridview搜索

Question

我的搜索功能無法正常工作。不知道我錯了哪裏。

我的代碼是

public partial class _Default : System.Web.UI.Page 
{ 
SqlConnection conn = new SqlConnection(@"Data Source=.\sqlexpress;Initial Catalog=foc; Trusted_Connection=yes;"); 
protected void Page_Load(object sender, EventArgs e) 
{  
    if (!IsPostBack) 
    {    
     BindGrid(); 
     Button1_Click(Button1, null); 
     TextBox1_TextChanged(TextBox1, null); 
    } 
} 

protected void BindGrid() 
{ 
    DataSet ds = new DataSet();   
    conn.Open(); 
    string cmdstr = "SELECT MIN([sddoc]) AS[sddoc],[Soldtopt], [tradingname], [REP],MIN([DELTXT]) AS[Preseller Text], SUM(try_cast([Orderqty] as float)) AS[Orderqty],count(distinct Orderqty) as Qtycount , [DlvDate], SUM(try_cast(Netvalue as float)) as Netvalue, count(distinct SDDoc) as Salesdoc , count(distinct case when Netvalue = '0' then 1 else null end) as ZeroValue , count(distinct SDDoc) - count(distinct case when Netvalue = '0' then 1 else null end) As Result FROM [FOC].[dbo].[foc] where dlvdate = @dlvdate GROUP by Soldtopt,tradingname,REP,DlvDate HAVING SUM(try_cast(Netvalue as float)) = 0 and count(distinct SDDoc) = 1 and count(distinct case when Netvalue = '0' then 1 else null end) = 1"; 

    SqlCommand cmd = new SqlCommand(cmdstr, conn); 
    cmd.Parameters.AddWithValue("@dlvdate", TextBox1.Text); 
    cmd.ExecuteNonQuery(); 
    SqlDataAdapter adp = new SqlDataAdapter(cmd); 
    adp.Fill(ds); 
    conn.Close(); 
    gvEmployeeDetails.DataSource = ds; 
    gvEmployeeDetails.DataBind(); 

} 
protected void gvEmployeeDetails_OnRowDataBound(object sender, GridViewRowEventArgs e) 
{ 
    if (e.Row.RowType == DataControlRowType.DataRow) 
    { 
     Label lblEmpID = (Label)e.Row.FindControl("lblEmpID");   
     GridView gv_Child = (GridView)e.Row.FindControl("gv_Child"); 

     string txtempid = lblEmpID.Text; 

     DataSet ds = new DataSet(); 
     conn.Open(); 
     string cmdstr = "Select * from [FOC].[dbo].[foc] where sddoc=@sddoc"; 
     SqlCommand cmd = new SqlCommand(cmdstr, conn); 
     cmd.Parameters.AddWithValue("@sddoc", txtempid); 
     SqlDataAdapter adp = new SqlDataAdapter(cmd); 
     adp.Fill(ds); 
     cmd.ExecuteNonQuery(); 
     conn.Close(); 
     gv_Child.DataSource = ds; 
     gv_Child.DataBind(); 

    } 
}

嗨問題是通過結合使用按鈕單擊網格解決。
