推荐答案

正则表达式在ajax中无法正常工作.建议您使用
FilteredTextBoxExtender

示例:

Hi,

Regular expression does not work correctly in ajax. Advise you to use
FilteredTextBoxExtender

Example:

 <cc1:filteredtextboxextender validchars="0123456789+()" filtermode="ValidChars" xmlns:cc1="#unknown">
     TargetControlID="txtMobileNo" ID="ftxtMobileNo" runat="server">
</cc1:filteredtextboxextender>
