Re: Server side controls vs client side script.

This argumention is right and false - it depends on the way you =
implement your pages and is not .NET specific.

Sample:
You have a HTML Form with 20 kByte that uses Data of 1 kByte that is =
displayed and modified in 4 fields.

Case 1:
If you implement a server-site validation on every onchange-event the =
data is uploaded 4 times to the server for validation and 4 times the =
whole Page with data comes back to the client.
The final submit only tranfers the data.
Sum: ~ 21 + 4*(1+21) + 1 =3D 110 kbyte (if no errors in input)

Case 2:
You implement a server-site validation when the form is submitted there =
is no up/download while the values in the fields are changed.
Sum: ~ 21 + 1 =3D 22 kbyte (if no errors in input)

Case 3:
Same as Case 2 but you ADD a client-site validation.
You only have to add some HTML+JScript code that's transfered to the =
client.
Sum: ~ 21 + 1 + 2 =3D 24 kbyte (even if some errors while editing input)

Case 4:
Server-site validation is done by calling a WebService. It is possible =
to use the IE as a direct client to a webservice and this enables a full =
featured validation including reference data-lookup.
Sum: ~ 21 + 1 + 4*1 + 2 =3D 28 kbyte (even if some errors while editing =
input)

Discuss:
All of these cases can be implemented on every server-plattform (.NET, =
ASP, JSP, PHP,...) so this is not .NET specific.
Some people use every new feature they can get; they should think about =
a <asp:label runat:server ...>. Programming the Case 1 is also done in =
some of the .NET Samples but showing the possibilities doesn't mean that =
you have to us them. Mixing HTML and ASP.NET objects also makes sense.

Case 4 is not suppored very well by the existing ASP.NET classes but =
calling webservices directly from the client enables a lot of features. =
We implement our solution this way.

    Some client-side code purist argue that ASP.NET's server side =
controls put
    to much of a load on the server and cause to many round trips to the
    server.  When you are pitching ASP.NET and run into these arguments =
how do
    you answer these criticisms of ASP.NET?
