动态创建控件 [英] Create controls dynamically

问题描述

在按下按钮之前创建控件并将其放在给定的位置。

我认为可能这样

  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（）; 
  

但问题在于按下按钮时，同名的控件被创建。如何避免

什么da ........
i写了，也没有例外，我期待它，因为控件已经包含 btnAdd 而不是许多按钮创建许多你想要的。
访问它们将是问题，但它将通过 @drachenstern 方法正确解决

  private void button1_Click_1（object sender，EventArgs e）
 {
按钮btnAdd = new Button（）; 
 
 btnAdd.BackColor = Color.Gray; 
 btnAdd.Text =添加; 
 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

你可以尝试解决方案发布了这里。它将在构造函数中动态创建5个按钮。只需将代码移动到按钮点击事件，它应该动态添加按钮并使用单击事件注册。

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.
