You can use PageMethods :
http://www.dotnetcurry.com/showarticle.aspx?ID=109
http://msdn.microsoft.com/en-us/library/system.web.ui.page_methods(v=vs.110).aspx

Add this in your page :
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true"/>

Open in new window


Public Shared Function FunctionName(ByVal parame As String) As String
' DO SOMETHING
End Function

Open in new window


Javascript, client side :
function RunServerSideFunction(fieldID, target) {    
     var value = document.getElementById(fieldID).value;
     PageMethods.FunctionName(value, Success, Failed, target);
}
 
function Success(result, fieldID) {    
    document.getElementById(fieldID).value = result;
}
 
function Failed(error, fieldID) {
     alert(error);
}
