Greeting

I search long time and test many formula to validate Arabic character.

Scenario describe:

I have a form contain a Text box (title) and another text box field (description)

I designed a form to allow user to write in both languages (Arabic or English ) or in some time a paragraph containing both of last languages.

 -Text box mode(Multiline).

-Accept (Arabic & English) with spaces and new line(Enter).

first time I used this formula for my propose:

  

I followed that post 

https://forums.asp.net/t/1995192.aspx?Arabic+letters+English+letters+only+regular+expression+No+Numbers+

1. ^[\u0600-\u065F\u066A-\u06EF\u06FA-\u06FFa-zA-Z]+[\u0600-\u065F\u066A-\u06EF\u06FA-\u06FFa-zA-Z-_]*$  

 But last formula not work correctly.

I moved to another formula like this

1. ^[\u0600-\u065F\u066A-\u06EF\u06FA-\u06FFa-zA-Z\s\w*]  

 and problem still as it.

what anyone have an idea to describe what happening?

Hi aktham85,

As far as I think,[a-zA-Z] is English character and [u0600-\u06FF] is Arabic character. So,you could refer to below demo only math Arabic and English characters.Just like this:

<asp:TextBox ID="TextBox1" runat="server" TextMode="MultiLine"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ErrorMessage="only Arabic and  English" ControlToValidate="TextBox1" ValidationExpression="^(?:[a-zA-Z\s@,=%$#&_\u0600-\u06FF\u0750-\u077F\u08A0-\u08FF\uFB50-\uFDCF\uFDF0-\uFDFF\uFE70-\uFEFF]|(?:\uD802[\uDE60-\uDE9F]|\uD83B[\uDE00-\uDEFF])){0,}$"></asp:RegularExpressionValidator>
