添加多个文本框并检索其值。 [英] Add multiple text boxes and retrieve there value.

问题描述

我正在开发一个窗口应用程序。我希望当我点击添加按钮时，它会动态创建一个一个文本框。我将数据存储在sql server数据库中并在数据网格视图中显示它们。那么你可以帮我添加和查看文本框值。

解决方案

要动态创建一些文本框，你可以在下面的代码中添加button_click的范围：

  private   void  button1_Click（ object  sender，EventArgs e）
 {
 TextBox tb1 =  new  TextBox（）; 
 tb1.ID =   textBox1; 
 tb1.Text =  嗨; 
 yourform.Controls.Add（tb1）
} 

此外，请尝试阅读以下帖子：

C＃按钮单击

http://social.msdn.microsoft.com/Forums/en-US/adodotnetdataproviders/thread/71526c3e-66a5-4309-bdc9-9e29064faef6 [ ^ ]

尝试：

  int  x =  20 ;  int  y =  20 ;  int  margin =  5 ; 
  for （ int  i =  0 ; i <   10 ; i ++）
 {
 TextBox tb =  new  TextBox（）; 
 tb.Location =  new  Point（x，y）; 
 y + = tb.Height + margin; 
 Controls.Add（tb）; 
} 

将创建十个文本框并将其显示在垂直堆栈中。访问它们：

  foreach （控制c  in 控制）
 {
 TextBox tb = c  as  TextBox; 
  if （tb！=  null ）
 {
 .. 。
} 
} 

你究竟如何将它们保存到数据库取决于你 - 我不知道你的数据库结构，或者你正在尝试使用数据。

I working on a window application. I want that when I click on add button then it creates one by one text boxes dynamically. I store the data in the sql server database & show them in a data grid view. So can u help me for add and view the text box values.

解决方案

To create some text boxes dynamically you can add in scope of button_click following code:

private void button1_Click(object sender, EventArgs e)
{
   TextBox tb1 = new TextBox();
   tb1.ID = "textBox1";
   tb1.Text = "Hi";
   yourform.Controls.Add(tb1)
}

Also, try read the following post:
"C# Insert into SQL when button click"
http://social.msdn.microsoft.com/Forums/en-US/adodotnetdataproviders/thread/71526c3e-66a5-4309-bdc9-9e29064faef6[^]

Try:

int x = 20; int y = 20; int margin = 5;
for (int i = 0; i < 10; i++)
   {
   TextBox tb = new TextBox();
   tb.Location = new Point(x, y);
   y += tb.Height + margin;
   Controls.Add(tb);
   }

Will create ten text boxes and display them in a vertical stack. To access them:

foreach( Control c in Controls)
   {
   TextBox tb = c as TextBox;
   if (tb != null)
      {
      ...
      }
   }

Exactly how you save them to your database is up to you - I have no idea of your DB structure, or what you are trying to with the data.
