问题描述
我在表1两个按钮,一个是ShowForm2按钮,一个是BUTTON1按钮。
按钮1默认情况下禁用。当我点击ShowForm2按钮,表2显示。
所以,我想的是,当我点击表格2的按钮2,它会在形式上1启用BUTTON1。
所以,我尝试code像这样在我的窗口2类:
公共部分类窗体2:表
{
布尔enable_form1_button1;
公共BOOL Enable_form1_button1
{
{返回this.enable_form1_button1; }
集合{this.enable_form1_button1 =价值; }
}
公共窗体2()
{
的InitializeComponent();
} 私人无效button2_Click(对象发件人,EventArgs的发送)
{
enable_form1_button1 = TRUE;
}
}
然后在我的Form1类中,我期待得到enable_form1_button1 = true将传递到形式1,使我的表格1 BUTTON1。但如何做到这一点?
公共部分Form1类:表格
{
公共Form1中()
{
的InitializeComponent();
} 私人无效btb_Showfrm2_Click(对象发件人,EventArgs的发送)
{
窗体2 FRM2 =新Form2的();
frm2.Show();
button1.Enabled = frm2.Enable_form1_button1; //我把它放在这里,它只是似乎并不正确
}
}
Form1.cs的
公共部分Form1类:表格
{
公共Form1中()
{
的InitializeComponent();
button1.Enabled = FALSE;
} 私人无效button2_Click(对象发件人,EventArgs的发送)
{
窗体2 oFrm2 =新Form2的();
oFrm2.evtFrm + =新ShowFrm(oFrm2_evtFrm);
oFrm2.Show();
} 无效oFrm2_evtFrm()
{
button1.Enabled = TRUE;
}
}
Form2.cs
公共委托无效ShowFrm();
公共部分类窗体2:表
{
公共事件ShowFrm evtFrm;
公共窗体2()
{
的InitializeComponent();
} 私人无效的button1_Click(对象发件人,EventArgs的发送)
{
如果(evtFrm!= NULL)
{
evtFrm();
}
}
}
I have two buttons in Form 1, one is "ShowForm2" button and one is "button1" button.
Button 1 is disable by default. And when I click "ShowForm2" button, Form 2 will show.
So, what I want is, when I click the "button2" in form 2, it will enable the "button1" in form 1.
So, I try to code like this in my form2 class:
public partial class Form2 : Form
{
bool enable_form1_button1;
public bool Enable_form1_button1
{
get { return this.enable_form1_button1; }
set { this.enable_form1_button1 = value; }
}
public Form2()
{
InitializeComponent();
}
private void button2_Click(object sender, EventArgs e)
{
enable_form1_button1 = true;
}
}
Then in my Form1 class, I am expecting to get the "enable_form1_button1 = true" to pass into form 1 and enable my form 1 button1. But how to do this?
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void btb_Showfrm2_Click(object sender, EventArgs e)
{
Form2 frm2 = new Form2();
frm2.Show();
button1.Enabled = frm2.Enable_form1_button1; // I put it here, and it just does not seems right
}
}
Form1.cs
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
button1.Enabled = false;
}
private void button2_Click(object sender, EventArgs e)
{
Form2 oFrm2 = new Form2();
oFrm2.evtFrm += new ShowFrm(oFrm2_evtFrm);
oFrm2.Show();
}
void oFrm2_evtFrm()
{
button1.Enabled = true;
}
}
Form2.cs
public delegate void ShowFrm();
public partial class Form2 : Form
{
public event ShowFrm evtFrm;
public Form2()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
if (evtFrm != null)
{
evtFrm();
}
}
}
