I want a button that when the user clicks on it validates in both server side and client side regular expressions.
for example
<asp:Button ID="btnLogin" runat="server" onclick="C_Buttonk" onclick= "js_button" Text="Login" />
Then button would call both functions from JS and C# hence serverside and client side, but the problem is, it doesn't work!
How would I go around possibly doing this without it being too complicated, I just need a simple fix.
Thanks Olly
