if ur sql->sp requires a datatime datatype with another param it will works fine in your local dev machine. bt in some cases it doesnt work with the IIS 7.5.
solution1:�either u can change the datetime datatype with varchar(if it is possible). if not then…
here is the solution:
just add this under <system.web>
<globalization culture="en-GB" uiCulture="en-GB" requestEncoding="utf-8" responseEncoding="utf-8" />
