问题描述
向大家问好
我以form1作为父母,而我的孩子则是form2
在form1的按钮单击事件上,显示了form2的一个实例,并且该按钮被拒绝以不显示另一个实例,我想在form2的示例关闭时再次启用该按钮,我的用户可以单击它.
在form2的关闭表单上,我编写此代码

}
但这不起作用
请帮帮我.

推荐答案
更改它:将处理程序移到form1中:
Form1按钮单击事件:
Change it: move the handler into form1:
Form1 button click event:
Form2 f = new Form2();
f.FormClosing += new FormClosingEventHandler(Form2_FormClosing);
myButton.Enabled = false;
f.Show();
然后将处理程序添加到Form1:
Then add the handler to Form1:
void Form2_FormClosing(object sender, FormClosingEventArgs e)
{
myButton.Enabled = true;
}
