两个窗体之间传值的问题



图一窗口点击圈中的按钮，打开图二的窗口.
问题：如何在图二窗口当按下确定按钮，将图二的textbox内容传递到图一的textbox， 思路是有，但是窗体之间传递没弄懂 ，谢谢!

你可以用委托，在第二个窗台里面，实现第一个窗台里面定义的委托；或者你用单例模式做数据存储及传递。

 public partial class ShowInsert : Form
    {
        public ShowInsert()
        {
            InitializeComponent();
        }

这么麻烦干嘛啊！
根据窗体二的DialogResult 来判断是否需要把查询条件返回就OK了
窗体二定义一个全局
Public string Condition
{
get{return txt.text.Trim();}//txt是你窗体二查询条件控件。
}
窗体二确定按钮中返回：DialogResult = System.Windows.Forms.DialogResult.OK;

窗体一种判断如果返回的是OK，那么直接用窗体二的实例.Condition就拿到你要的条件了！

[解决办法]

定义一个静态类  
//public static class common
{
  public static string content;
}
//第二个窗体中 
common.content=textBox1.text;

//第一个窗体中
 textBox.text=common.content;

web做多了吧，winform不存在传值问题。都在内存里，控制访问权限就行了（public）。问题是要怎么找到相应的对象。

在窗体2中实例化窗体1类，就可以访问窗体1中的属性了。这位同学应该是GIS专业的吧
