呼叫事件，當第二個窗體關閉

Question

我有兩種形式，我打開和ShowDialog的第二種形式是這樣的：

Recieving_Stock_Form f = new Recieving_Stock_Form(); 
f.Username = Username; 
f.Role = Role; 
f.Date = monthCalendar1.SelectionStart.ToString(@"yyyy\/MM\/dd"); 
f.ShowDialog(); 

現在，當我關閉第二種形式我想觸發第一個事件形式 EG

void txtStockCount_TextChanged(object sender, EventArgs e) 

任何想法，我可以看一下這個還是怎麼辦呢？

感謝

Answer 1

的ShowDialog是模態，因此會阻止executiong，所以當你關閉它，執行接下來的事情。

你可以這樣做：在Form1

Recieving_Stock_Form f = new Recieving_Stock_Form(); 
f.Username = Username; 
f.Role = Role; 
f.Date = monthCalendar1.SelectionStart.ToString(@"yyyy\/MM\/dd"); 
f.ShowDialog(); 
// it will continue here when the form is closed. 
txtStockCount_TextChanged(this, EventArgs.Empty); // or assign the variable directly. 

Answer 2

，假設你的代碼是這樣

Recieving_Stock_Form f = new Recieving_Stock_Form(); 

您可以添加代碼

f.Form_Closing += ExampleHandler; 

ExampleHandler(object sender, FormClosingEventArgs e) 
{ 
    //Do stuff 
} 

Answer 3

有兩個事件，你可以處理 - FormClosed和FormClosing，取決於您的決定ñ。

f.FormClosed += f_FormClosed; 

private void f_FormClosed(object sender, FormClosedEventArgs e) 
{ 
    //Call your function or do whatever you want 
} 

Answer 4

我寧願沒有欺騙表格;相反，我建議從Recieving_Stock_Form的值賦給txtStockCount：

using (Recieving_Stock_Form f = new Recieving_Stock_Form()) { 
    f.Username = Username; 
    f.Role = Role; 
    f.Date = monthCalendar1.SelectionStart.ToString(@"yyyy\/MM\/dd"); 

    // == DialogResult.OK - let user have a chance to cancel his/her input 
    if (f.ShowDialog() == DialogResult.OK) { 
    //TODO: put the right property here 
    txtStockCount.Text = f.StockCount.ToString(); 
    } 
}
