[英]How to open a new form then from the second form go back to the first form without closing and reopening the first form
[英]Reloading windows form without closing and reopening
我有一個用c#編寫的Windows窗體應用程序。 當有人按下“清除”按鈕時,我想重新加載表單。 但我無法實現調用Load事件。這些行也不起作用:
this.Refresh();
this.Load +=new EventHandler(Grafik_Load); // 'Grafik' is the name of the form.
我該怎么辦? 謝謝你幫忙..
將'load'代碼放在一個單獨的函數中,並從您自己的代碼/ Load事件處理程序中調用該函數。
private void callonload()
{
//code which u wrriten on load event
}
private void Form_Load(object sender, EventArgs e)
{
callonload();
}
private void btn_clear_Click(object sender, EventArgs e)
{
callonload();
}
我發現hide / show,show部分創建了同一個表單的另一個實例,所以我最好配置當前的一個,創建它的新實例,並顯示它。
Grafik objFrmGrafik = new Grafik ();
this.Dispose();
objFrmGrafik .Show();
Home是MDI-Form名稱。 我測試過了。
home.ActiveForm.Dispose();
home sd = new home();
sd.Show();
//it is a good idea to use the 'sender' object when calling the form load method
//because doing so will let you determine if the sender was a button click or something else...
private void button2_Click(object sender, EventArgs e)
{
//you may want to reset any global variables or any other
//housekeeping before calling the form load method
Form1_Load(sender, e);
}
private void Form1_Load(object sender, EventArgs e)
{
if (sender is Button)
{
//the message box will only show if the sender is a button
MessageBox.Show("You Clicked a button");
}
}
