用另一種方法給dinamically創建的文本框賦值

Question

請不要立刻給我downvotes，我在這裏問的同樣的問題how to assign values to textbox in another method which was dynamically created in c sharp，但FindControl方法不存在於當前上下文中。

這裏是我的代碼

private void btnOkreni_Click(object sender, EventArgs e) 
{ 
     TextBox txt = new TextBox(); 
     txt.Name = "txtBoxOpis"; 
     txt.Text = izabrana[0].Opis; 
     Controls.Add(txt); 
} 

private void btnSledeca_Click(object sender, EventArgs e) 
{ 
    foreach (Karta k in izabrana) 
     { 
      if (k == izabrana[0]) 
      { 
       continue; 
      } 
      txtBoxPojam.Text = k.Pojam; 

      //((TextBox)FindControl("txtBoxOpis")).Text = k.Opis; 
     } 
} 

Answer 1

使TextBox txt;作爲公共變量，之後用txt = new TextBox初始化，比你能夠在主類中處處得到這個
