控件的应用

1. 菜单

  1.1 MaskedTextBox控件

      新建Form, 增加3个Label 和 3个MaskedtextBox

  

      在Form_load代码中增添如下

1 private void Form1_Load(object sender, EventArgs e)
2         {
3             maskedTextBox1.Mask = "00/00/0000";
4             maskedTextBox2.Mask = "00";
5             maskedTextBox3.Mask = "000-0000-0000";
6         }

  可以给每个MaskedtextBox的MaskInputRejected事件添加处理机制, 例如其中的一个:

1 private void maskedTextBox1_MaskInputRejected(object sender, MaskInputRejectedEventArgs e)
2         {
3             MessageBox.Show("Error");
4         }

  MaskedTextBox控件是增强型的textBox控件, 使用掩码区分正确和不正确的用户输入. 通过Mask属性可实现:

  <1>必需的输入字符

  <2>可选的输入字符

      <3>掩码中的给定位置所需的输入类型

      <4>输入字符的特殊处理:例如, 将字母字符转换为大写字母

 

  1.2 NumericUpDown

  在Form上添加Label和NumericUpDown

1 private void numericUpDown1_ValueChanged(object sender, EventArgs e)
2         {
3             this.label1.Text = "";
4             string str = "当前选择值为:";
5             this.label1.Text = string.Format("{0}{1}",str,this.numericUpDown1.Value.ToString());
6         }

  

  

  1.3 ProgressBar

 1 private void button1_Click(object sender, EventArgs e)
 2         {
 3             int count = 1000; //测试值总数1000
 4             progressBar1.Minimum = 0; //最小值
 5             progressBar1.Value = 0; //初始值
 6             progressBar1.Maximum = 1000; //最大值
 7             for (int i = 0; i < count; i++)
 8             {
 9                 this.progressBar1.Value++;
10                 Application.DoEvents();
11                 label1.Text = "总量" + count.ToString() + " ,剩余" + Convert.ToString(count-i-1);  //这种数值转换也值得学习
12             }
13         }

  

 

  1.4 DateTimePicker

private void dateTimePicker1_ValueChanged(object sender, EventArgs e)
        {
            this.label1.Text = "今天是今年的第" + this.dateTimePicker1.Value.DayOfYear.ToString() + "";
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            this.label1.Text = "今天是今年的第" + this.dateTimePicker1.Value.DayOfYear.ToString()+"";
        }

  

 

  1.5 TabControl

  在Form上添加TabControl, 在其TabPage属性中修改其Text属性, Name还是默认的

  先放置几个GroupBox, 再在其中添加几个控件, 值得注意的是一个groupBox中只能选择一个radiobutton, 布局如下

  

  

 1 private void button1_Click(object sender, EventArgs e)   //下一步按钮
 2         {
 3             if (tabControl1.SelectedIndex == 0)
 4             {
 5                 tabControl1.SelectedIndex = 1;
 6             }
 7 
 8             if (radioButton1.Checked)
 9             {
10                 this.label4.Text = "用户是 男";
11             }
12             else
13                 this.label4.Text = "用户是 女";
14         }
15 
16 
17 
18         private void button2_Click(object sender, EventArgs e)  //返回
19         {
20             if (tabControl1.SelectedIndex == 1)
21             {
22                 tabControl1.SelectedIndex = 0;
23             }
24             this.label4.Text = " ";
25         }

  点击下一步按钮就会到第二个选项卡, Label会显示是男是女

 

  1.6 LinkLabel

  类似超链接

  

 private void linkLabel1_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
        {
            System.Diagnostics.Process.Start("http://zc.qq.com/chs/index.html");
        }  

  点击申请新用户, 浏览器会自动打开如下网址  "http://zc.qq.com/chs/index.html"  

 

  1.7 WebBrowser

  

  在地址栏输入baidu之后, 回车

  

  在Form上添加Menustrip,分别为1234, 添加ToolStrip分别为 后退 前进 主页 刷新四个按钮, 和一个ToolStripTextBox

 

 1 private void toolStripButton1_Click(object sender, EventArgs e)  //后退
 2         {
 3             webBrowser1.GoBack();
 4         }
 5 
 6         private void toolStripButton2_Click(object sender, EventArgs e) //前进
 7         {
 8             webBrowser1.GoForward();
 9         }
10 
11         private void toolStripButton3_Click(object sender, EventArgs e)  //刷新
12         {
13             if (!webBrowser1.Url.Equals("about:blank"))
14             {
15                 webBrowser1.Refresh();
16             }
17         }
18 
19         private void toolStripButton4_Click(object sender, EventArgs e)  //主页
20         {
21             webBrowser1.GoHome();
22         }
23 
24         private void webBrowser1_Navigated(object sender, WebBrowserNavigatedEventArgs e)
25         {
26             toolStripTextBox1.Text = webBrowser1.Url.ToString();   //TextBox刷新为当前Url
27         }
28 
29         private void toolStripTextBox1_KeyDown(object sender, KeyEventArgs e)
30         {
31             if (e.KeyCode == Keys.Enter)  //回车键
32             {
33                 Navigate(toolStripTextBox1.Text);   
34             }
35         }
36     
37 
38         private void Navigate(String address)
39         {
40             if (!address.StartsWith("http://") && !address.StartsWith("https://"))
41             {
42                 address = "http://" + address + ".com";
43             }
44             try
45             {
46                 webBrowser1.Navigate(new Uri(address));
47             }
48             catch(System.UriFormatException)
49             {
50                 return;
51             }
52         }

 

 

  1.8 HScrollBar

    

 1 private void hScrollBar1_Scroll(object sender, ScrollEventArgs e)
 2         {
 3             pictureBox1.BackColor = Color.FromArgb(255, hScrollBar1.Value, hScrollBar2.Value, hScrollBar3.Value);
 4         }
 5 
 6         private void hScrollBar2_Scroll(object sender, ScrollEventArgs e)
 7         {
 8             pictureBox1.BackColor = Color.FromArgb(255, hScrollBar1.Value, hScrollBar2.Value, hScrollBar3.Value);
 9         }
10 
11         private void hScrollBar3_Scroll(object sender, ScrollEventArgs e)
12         {
13             pictureBox1.BackColor = Color.FromArgb(255, hScrollBar1.Value, hScrollBar2.Value, hScrollBar3.Value);
14         }
