在另一页中显示结果可帮助我 [英] displaying result in another page assist me plz

问题描述

亲爱的朋友，如果我想知道这是一个简单还是愚蠢的问题，我会感到很抱歉
如何在另一页中显示结果

例如:

index.aspx将有一个文本框，我们可以在其中输入值并提交按钮
我们只要单击提交"按钮，它就会转到result.aspx页并显示结果.

我只想要我知道的有关SQL gridview和按钮事件触发的代码部分

所以请帮我解决这个问题，先谢谢


index.aspx(文本框和按钮)
result.aspx(在网格视图中显示)

在default.aspx中

              <asp:Label ID="Label2" runat="server" Text="error label">
          </div>
          </form>

在result.cs

in result.cs

using System;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;

public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (Page.PreviousPage != null)
        {
            TextBox txt1 = (TextBox)(Page.PreviousPage.FindControl("TextBox1.text"));
        }
        BindFiles();
    }
    private void BindFiles()
    {
        DataTable table = new DataTable();

        // get the connection
        SqlConnection _conn1 = new SqlConnection(@"conn string");
        {
            // write the sql statement to execute
            string sql = "select * from studsub where sid=TextBox1";
            
            // instantiate the command object to fire
            using (SqlCommand cmd = new SqlCommand(sql, _conn1))
            {
                // get the adapter object and attach the command object to it
                using (SqlDataAdapter ad = new SqlDataAdapter(cmd))
                {
                    // fire Fill method to fetch the data and fill into DataTable
                    ad.Fill(table);
                }
                // DataAdapter doesn't need open connection, it takes care of opening and closing the database connection
            }
        }
        GridView1.DataSource = table;
        GridView1.DataBind();
    }
}

请检查我的代码，并告诉我在哪里放置哪些代码以及必须放置哪些代码

please check my code and tell me where to put which code and what code has to put

推荐答案

您可以使用response.redirect转移到新页面并使用查询字符串，将结果值传递到下一页.

you can use response.redirect to transfer to new page & use a query string to pass resultant value to next page.

您可以使用Session将数据从index.aspx发送到result.aspx页面:

在index.aspx中，将结果保存在会话中:

Hi,

You can use Session to send data from index.aspx to result.aspx page :

In index.aspx save result in session:

Session["Result"] = txtResult.Text;

在result.aspx中从会话获取结果

In result.aspx get result from session

string Result = Session["Result"].ToString();

下面是从index.aspx传递查询字符串的示例

将以下代码放入index.aspx按钮单击事件中

Below is the sample to pass query string from index.aspx

put the below code in index.aspx button click event

Reponse.Redirect("result.aspx?Value=" + textbox.text)

从result.aspx页面加载事件中删除以下代码

remove your below code from result.aspx Page Load event

if(Page.PreviousPage != null)
{
TextBox txt1 = (TextBox)(Page.PreviousPage.FindControl("TextBox1"));
}

在result.aspx页面加载事件中使用我的以下代码

use my below code in result.aspx Page Load event

if (Request.QueryString.Get("Value") != null)
       string strValue = (Request.QueryString.Get("Value"))
