ASP.NET TextBox的内容验证！ [英] ASP.NET TextBox's content validation !

我创建了一个网页表单，其中包含名为txtEmpNo的文本框。在那个文本框中我只想输入数字。另一方面，我想在输入A-Z时将内容限制为数字，文本框不应该允许这样做！

如何解决这个问题？我已经在ASP.Net中看到了CustomValidation控件，但我不知道如何验证ASP.Net中文本框的内容以验证使用它！

解决方案

< blockquote>尝试使用蒙面编辑控件 [ ^ ]。

< blockquote>使用RegularExpression验证器并使用它：^ [0-9] {1,7}

作为正则表达式。然后，您可以将错误消息更改为您想要的任何内容。

I have created a a web form that has text box called ''txtEmpNo''. At that text box I only want to enter numbers. In other hand I want to restrict the content to numbers when enter A - Z that text box should not allow to do that!

I use C#.Net with ASP.Net

How am going to solve that? I already seen the CustomValidation control in ASP.Net but I do not know how to validate the content of a text box in ASP.Net to validate using it!

If you can please help me to do that!

Thanks

解决方案

Try using the Masked Edit Control[^] from the ASP.NET AJAX Control Toolkit.

Use a RegularExpression validator and use this: ^[0-9]{1,7}

as your regular expression. Then you can change the error message to whatever you want.
