逻辑
动态加载控件1,当点击控件一中的按钮时把控件1中的第一个txt文本框数据传入控件2内的标签,
当点击控件2中的按钮把控件而中的txt文本输入控件一中的标签,
[解决办法]
1、定义两个,公共属性。 public string lblText{get;this.lable.text = value}; public string lblText2{get;this.lable2.text = value}; 然后 this.textbox.text = lblText;
[解决办法]
控件1:
using System;using System.Collections.Generic;using System.ComponentModel;using System.Drawing;using System.Data;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms;namespace WindowsFormsControlLibrary1{ public partial class UserControl1: UserControl { public UserControl1() { InitializeComponent(); } private string text1; public string Text1 { get { return text1; } set { text1 = value; this.label1.Text = text1; } } public delegate void myDelegate(eventData e); public event myDelegate btClick; private void button1_Click(object sender, EventArgs e) { this.text1 = this.textBox1.Text;//单点击按钮时 eventData _eventdata=new eventData(); _eventdata.tempData=this.Text1; if (btClick!=null) { btClick(_eventdata); } } } public class eventData : EventArgs { public string tempData; }}
