案例1
The following example contains two forms in an .aspx file. The first form has a label with the text "Please enter a number from 1 through 100", an input box to input a number, a RangeValidator control that checks that the input value is a number from 1 through 100, a RequiredFieldValidator control that checks that the input field isn't empty, and a submit button. The second page is activated by the submit button on the first page, and displays a response. If the input value validates as an error, an error message is displayed:
下面的案例包含了 .aspx 文件中的两张表单。第一张表单包含一个名为“Please enter a number from 1 through 100” 的标签，一个输入框，一个用于确认输入值范围从数字1-100的RangeValidator 控件，以及一个提交按钮。第二张页面将被第一张页面中的提交按钮激活。如果输入值确认出现错误，那么将显示一段错误信息：
