创建控件动态 [英] Create controls dynamically

问题描述

我想知道这是否可能在C＃中的winform。

当按下曾经按钮创建控制，并将其放置在指定位置。

我认为这是可能是这样

 私人文本框txtBox =新的TextBox（）; 
私人按钮btnAdd =新按钮（）; 
私人列表框lstBox =新的ListBox（）; 
私人复选框chkBox =新的复选框（）; 
私人标签lblCount =新的Label（）; 
  

但问题在于当按下按钮过同名控制是created.How避免

I写什么大........没有例外，我期待它，因为控制已包含 btnAdd 而不是尽可能多的按钮来创建你想要的。
访问他们的将是问题，但它将被 @drachenstern 解决方法正确吗？

 私人无效button1_Click_1（对象发件人，EventArgs五）
 {
键btnAdd =新按钮（）; 
 
 btnAdd.BackColor = Color.Gray; 
 btnAdd.Text =添加; 
 btnAdd.Location =新System.Drawing.Point（90，25 + I）; 
 btnAdd.Size =新System.Drawing.Size（50，25）; 
 this.Controls.Add（btnAdd）; 
 I = I + 10; 
} 
  

解决方案

您可以尝试的解决方案，我 。它会动态地创建在构造函数中5个按钮。只需将代码移动到按钮单击事件，它应该动态地添加按钮并用点击事件。

I want to know if this is possible in c# winform.

create control when ever button is pressed and place it at given location.

I think it is possible like this

private TextBox txtBox = new TextBox();
private Button btnAdd = new Button();
private ListBox lstBox = new ListBox();
private CheckBox chkBox = new CheckBox();
private Label lblCount = new Label();

but the problem lies when ever button is pressed same name controls are created.How to avoid that

What da........ i wrote and no exception i was expecting it because control already contains btnAdd instead as many button create as many you want. Accessing them will be issue but it will be solved by @drachenstern method correct?

  private void button1_Click_1(object sender, EventArgs e)
        {
            Button btnAdd = new Button();

            btnAdd.BackColor = Color.Gray;
            btnAdd.Text = "Add";
            btnAdd.Location = new System.Drawing.Point(90, 25+i);
            btnAdd.Size = new System.Drawing.Size(50, 25);
            this.Controls.Add(btnAdd);
            i = i + 10;
        }

解决方案

You could try the solution I posted here. It will dynamically create 5 buttons in the constructor. Just move the code to the button click event and it should add the buttons dynamically and register with the Click events.
