如何使用某些按钮绑定列表框项？ [英] How to bind Listbox items with certain buttons ?

问题描述

我想将列表框项目绑定到同一窗口窗体上的某个按钮



更多解释：例如我在列表框中有一个项目，我选择它然后我按下一个按钮，然后在用户浏览器中打开一个链接，并确保列表框中的每个项目都有一个绑定到它的不同链接。



我怎么能这样做？

推荐答案

您好，



首先要显示网页浏览器，您必须添加表格的webbrowser组件。

为此：

Hello,

Firstly to display a web browser, you will have to add a webbrowser component to your Form.
To do that:

Quote：

1>打开工具箱

2>现在转到公共控制部分。

3>在那里你会找到网络浏览器组件。

4>使用鼠标将其添加到Windows窗体中。

1> Open the toolbox
2> Now go to the common controls section.
3> In that you will find the web browser component.
4> Using the mouse add it to the windows form.

接下来是：

The next thing is:

Quote：

1>在Windows窗体中添加一个列表框。

2> ;另外在窗体上添加一个按钮

1>Add a listbox to the windows form.
2> Also add a button to the windows form

现在看下面的代码：

Now look at the code below:

public partial class Form1 : Form
  {
      public Form1()
      {
          InitializeComponent();
      }

      public void bind_listbox()
      {
          listBox1.DataSource = new List<string>() {"codeproject","google"}; ///populate the list box with the sites you want to surf

      }


      /// <summary>
      /// Please note that when you add a web browser component then a text area will appear on your form itself where you will be able to browse to different sites. As shown in the code below.
      /// </summary>
      /// <param name="sender"></param>
      /// <param name="e"></param>
      private void button1_Click(object sender, EventArgs e)
      {


          switch (button1.Text) ///using the switch case navigate to the web sites
          {
              case "codeproject":

                  webBrowser1.Navigate("http://www.codeproject.com/");
                break;

              case "google":
                webBrowser1.Navigate("https://www.google.co.in/");

              break;


          }



      }

      private void Form1_Load(object sender, EventArgs e)
      {
          bind_listbox(); ///binding the listbox on form load. However in case of larger number of entries, form loading may take time and application may become unresponsive.
      }

      private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
      {
         button1.Text = listBox1.SelectedItem.ToString();  ////this event is fired when you select an item from the list box.
      }
  }

现在尝试一下。



请注意：

我已将网站浏览功能映射到一个按钮。如果你想要你可以使用多个按钮（根据我从你的问题中读到的内容）。



谢谢，

Now Try this out.

Please note:
I have mapped the web site browsing function to just one button. If you want you can do it using multiple buttons(according to what i read from your question).

Thanks,
