从另一个页面访问控件.ASP.Net
本文关键字:控件 ASP Net 访问 另一个 | 更新日期: 2023-09-27 18:31:36
嗯,情况就是这样...我在 Page1.aspx 中有一个元素 ( <h2 id="test"></h2>
),我想从 Page2 更改它.aspx(用户的管理区域...),有点...
test.InnerText = "testText";
如何从第二页访问此控件?这可能吗?
像往常一样,谢谢你们...
您需要获取表单的实例。 请参阅下面的两个表单项目表格 1
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
Form2 form2;
public Form1()
{
InitializeComponent();
form2 = new Form2(this);
}
private void button1_Click(object sender, EventArgs e)
{
form2.Show();
string results = form2.GetData();
}
}
}
表格 2
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form2 : Form
{
Form1 form1;
public Form2(Form1 nform1)
{
InitializeComponent();
this.FormClosing += new FormClosingEventHandler(Form2_FormClosing);
form1 = nform1;
form1.Hide();
}
private void Form2_FormClosing(object sender, FormClosingEventArgs e)
{
//stops form from closing
e.Cancel = true;
this.Hide();
}
public string GetData()
{
return "The quick brown fox jumped over the lazy dog.";
}
}
}
