validation at codebehind C# allowed only numeric values & after decimal allowed only 2 digits and not allowed alpha numeric value in textbox

推荐答案

验证的一种替代方法是使用掩码文本框.您也可以在ASP.NET中找到一些内容.

请参阅:
http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/MaskedEdit/MaskedEdit.aspx [ ^ ]，
http://www.asp.net/community/control-gallery/Item.aspx? i = 387 [ ^ ].

有关jQuery的纯JavaScript解决方案，请参见以下讨论:

One alternative to validations is a masked text box. You can find some for ASP.NET as well.

Please see:

http://www.asp.net/community/control-gallery/Item.aspx?i=387[^].

For the pure JavaScript solution with jQuery, please see this discussion:
