C＃在运行时添加带值的按钮

我想在运行时向我的选项卡控件添加一个有值的按钮。 很多教程都展示了创建与数据库连接时的工作方式。 有没有办法可以在不连接数据库的情况下完成？

在将数据输入文本框和单击保存后，新按钮应出现在另一个表单上的选项卡控件上。

Answer 1

在你保存按钮放：

private void btnSave_Click(object sender, EventArgs e) { x = 4; y = panel1 .Controls.Count * 70; Button newButton = new Button (); newButton.Height = 150; newButton.Width = 60; newButton.Location = new Point(x, y); newButton.Text= "your text"; newButton.Click += new System.EventHandler(Button_Click); tabControl1.TabPages [0].Controls.Add(newButton); } 

您还可以点击创建的新按钮：

 public void Button_Click(object sender, EventArgs e) { Button button = (Button)sender ; MessageBox.Show("Button is pressed "+button .Text ); }

我提出这样的决定

主要forms：

 namespace stackoverflow { public partial class MainForm : Form { private static Form2 new_form = new Form2(); public MainForm() { InitializeComponent(); new_form.Show(); } void Button1Click(object sender, EventArgs e) { new_form.CreateBtn( richTextBox1.Text ); } } } 

第二种forms：

 namespace stackoverflow { public partial class Form2 : Form { private Button btn = null; public Form2() { InitializeComponent(); } public void CreateBtn( string text ) { if ( btn == null ) { btn= new Button(); btn.Parent = this.tabPage1; } btn.Text = text; this.Refresh(); } } }
