To match a dash (hyphen) in a character class, the dash needs to be either first or last, or be escaped. The syntax you have given may work inadvertently, but is not correct because of the space at the end.

XML

try this one ,.. without regular expressions to restrict input text...

<asp:TextBox ID="txtSearch" runat="server" ></asp:TextBox>






 <ajaxToolkit:FilteredTextBoxExtender ID="fteSearch" runat="server" TargetControlID="txtSearch" FilterMode="InvalidChars"
InvalidChars=";|~!@#$%^*<>/\{}:';/*+_~`[]=&quot;">
 </ajaxToolkit:FilteredTextBoxExtender>
