如何在asp.net中删除动态创建的文本框

Question

我已经创建了用于添加文本框的代码，但我不知道要删除添加的文本框。

与我分享如何删除文本框;

counter ++; 
TextBox tb = new TextBox(); 
tb.ID = "TextBox" +counter; 
LiteralControl lineBreak = new LiteralControl(); 
PlaceHolder1.Controls.Add(tb); PlaceHolder1.Controls.Add(lineBreak); 
controlIdList.Add(tb.ID); 
ViewState["controlIdList"] = controlIdList; 

Answer 1

您可以从您的占位符像下面删除文本框：

protected void Remove(object sender, EventArgs e) 
    { 
     foreach (Control control in PlaceHolder1.Controls) 
     { 
      //Here you need to take ID from ViewState["controlIdList"] 
      if (control.ID == "TakeIDFromControlListsID") 
      { 
       Controls.Remove(control); 
      } 
     } 
    }
