TextBox应允许单词之间的空格，并且不允许在第一个单词之前和最后一个单词之后的单个空格 [英] TextBox should allow spaces between the words and not to allow even a single space before the First word and after the last word

问题描述

这是我的表达

 ValidationExpression =[A-Za-z] +（\ [[ -  Za-z] +）？\ s *

以上表达式允许

venkat

venkat kumar



但我需要输出如下。它应该接受以下所有内容。特殊字符和数字不允许

venkat

venkat kumar

venkat kumar ch

MVN Rao

解决方案

试试这个：

 ^ [a-zA-Z] +（\ S + [A-ZA-Z] +）* 

Ths is my Expression

ValidationExpression="[A-Za-z]+(\s[A-Za-z]+)?\s*"

The above expression allows
venkat
venkat kumar

But i need the output's as below. It should accept all the below. special characters and numbers should not allow
venkat
venkat kumar
venkat kumar ch
M V N Rao

解决方案

Try this:

^[a-zA-Z]+(\s+[a-zA-Z]+)*
