Question

想知道我在哪里错了。我是页面加载，但是当我点击搜索时（在我在姓氏字段中输入内容后），它只是时钟和时钟。

这是我的aspx.cs页面：

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Data.SqlClient;

  public partial class _Default : System.Web.UI.Page
    {
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        DataSet ds = new DataSet();

        using (SqlConnection con = new SqlConnection("SERVER=ServerName;Trusted_Connection=Yes;DATABASE=DBNAME"))
        {
            using (SqlCommand cmd = new SqlCommand())
            {
                cmd.CommandText = "customerSearchStoredProc";
                cmd.CommandType = CommandType.StoredProcedure;
                cmd.Parameters.AddWithValue("@lName", lNameTextbox.Text);
                cmd.Connection = con;

                SqlDataAdapter adapter = new SqlDataAdapter();
                adapter.SelectCommand = cmd;
                adapter.Fill(ds);

            }
            con.Close();
        }
        GridView1.DataSource = ds;
        GridView1.DataBind();

        /*SqlDataAdapter adp = new SqlDataAdapter("customerSearchStoredProc", con);
        adp.SelectCommand.CommandType = CommandType.StoredProcedure;
        adp.SelectCommand.Parameters.Add(new SqlParameter("@lName", System.Data.SqlDbType.Text));
        //adp.SelectCommand.Parameters.Add(new SqlParameter("@State", System.Data.SqlDbType.Text));
        adp.SelectCommand.Parameters["@lName"].Value = lNameTextbox.Text;
        //adp.SelectCommand.Parameters["@State"].Value = StateTextbox.Text;

        adp.Fill(ds);
        GridView1.DataSource = ds;
        GridView1.DataBind();*/


    }

    protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
    {

    }
}

这是我的aspx：

感谢您的帮助！

Answer 1

您的数据绑定正在调用点击。

OnDataBinding="Button1_Click"

在点击时，您调用数据绑定。

GridView1.DataBind();

对我来说，这看起来像是一个永远存在的循环。

Answer 2

我看到GridView没有显式定义列，并且你有AutoGenerateColumns = false。

这是代码中的遗漏，还是你的代码真的那样？如果是这样，那么GridView将不会显示任何内容。尝试设置AutoGenerateColuns =“true”，看看是否有任何显示。如果是这样，那么问题是您需要明确定义列。

将文本框数据传递给存储过程并将其返回到gridview
