仅输入文本框中的数字 [英] enter only numbers in Textbox

问题描述

大家好朋友，



我的项目基于Asp.net c＃



用户必须只输入数字，而不是文本框中的字母。



请你建议我，怎么做。



请帮助帮助



提前致谢。

解决方案

有办法制作发生这种情况，使用正则表达式，JavaScript验证等。



我更喜欢 Masked Textbox ： a href =http://www.codeproject.com/Articles/68834/Enhanced-Textbox-Control>增强的文本框控件 [ ^ ]

Google是你的朋友：好好经常拜访他。他可以比在这里发布问题更快地回答问题...



快速搜索得到超过400,000次点击： Google仅限数字textbox asp.net [ ^ ]



将来，请尽量自己做至少基础研究，不要浪费你的时间或我们的时间。

 <   asp：TextBox     ID   =  TextBox1    runat   = 服务器 > ;  <   / asp：TextBox  > ;  
 <   asp：RegularExpressionValidator     ID   =  RegularExpressionValidator1    runat   =  server    ControlToValidate   =  TextBox1  
   
                   ErrorMessage   = 输入有效数字    ValidationExpression   =  ^ \d

解决方案

There are ways to make this happen, using regular expression, JavaScript validation, etc.

I would prefer Masked Textbox for it: Enhanced Textbox Control[^]

Google is your friend: Be nice and visit him often. He can answer questions a lot more quickly than posting them here...

A very quick search gave over 400,000 hits: Google "only numbers in textbox asp.net"[^]

In future, please try to do at least basic research yourself, and not waste your time or ours.

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ControlToValidate="TextBox1"

        ErrorMessage="Enter a valid number" ValidationExpression="^\d
