分享窗体如何与用户控件交互
WinForm中
拿了个新窗体,在项目中加了个用户控件,功能很简单(一个ComBox,一个DataGridView用来进行下省市之间的连动)
在新窗体一个TextBox ,点一下这个文本框,显示用户控件,在ComBox里是省,选择之后,DataGridView里所属市就自动列出了,
这时,我想通过双击DataGridView里的某个市区,直接将该值写到窗体的TextBox里面去...同时这个用户控件隐藏
请高人赐教

采用用户控件，和交互数据可以进一步参考这里，

谢谢楼上的代码
因为我用的是用户控件
我是在用户控件上添加了几个属性,并且在用户窗体上来进行主窗体的值的改变
做法是 在主窗体的textbox的双击事件中将控件名传到用户控件,然后在用户控件中遍历父窗体 ...

在窗体的Form_Load事件中定义用户控件中的DataGridView双击事件
private void Form1_Load(object sender, EventArgs e)
{
foreach (Control control in this.userControl11.Controls)
{
if (control is DataGridView)
{
DataGridView dgv = (DataGridView)control;
dgv.CellContentDoubleClick += new DataGridViewCellEventHandler(dgv_CellContentDoubleClick);
}
}
}
void dgv_CellContentDoubleClick(object sender, DataGridViewCellEventArgs e)
{
//这样双击事件对外提供了，处理内容略
}

你可自定义事件,或者将你的ComBox,DataGridView在用户控件里中暴露接口也可.这样就你可以操作了.
方式有很多种.
