Validation Controls in .NET ( Client side or server side?)
 i have a very basic question. We have all these validation controls in asp.net ( required field, range validator and others)..my question is the required field validator is a server side control. So does that mean that it does a post back?..is it client side or server side control  The only controls that post back are buttons and other inputs where you set AutoPostback="True", such as a dropdownlist or a textbox.  Another way of posting back is using an UpdatePanel and placing a trigger in it for a specified control and/or event. All controls are considered clien...

When to use client side varidation and server side varidation in .net?
In .net or classic web application we can varidate user data either on client isde or server side. How to select which side varidate to be used? Thanks! Generally, I use both client and server validation. I make sure the input is in the correct format and reasonably valid on the client, then I verify the data on the server. The extent of validation also depends on the type of data that I need to validate.Here are a few references:Validating ASP.NET Server ControlsIntroduction to Validating User Input in Web FormsClient-Side Validation for ASP.NET Server ControlsSecurity Checklist...

communication between client side(java script) and server side in .net project
I have a question which is, when building a .net project, we are able to use server side code and client side code(java script). How do they communicate? Thanks Client Side coding works with the WebBrowser. So when ever you write client side code you have to keep browser compatability in your mind and you have to code. Server Side code works with Web Server (IIS) and it's ASPNET ISAPI's. The won't directly communicate with each other. But using AJAX you can all server side code from Client Side!

Getting my client-side variable over to server-side
Ok so I have looked at a few posts on this subject and I can't quite figure out how to apply the idea to what I am doing here. I am using javascript to take amounts from 7 different textboxes and add them up on the fly, dropping the total in the 8th textbox. After they fill in that information they click button (postback) to continue throughout the form... what I need is for the "textboxTotalAmt" to move from client-side to server-side.  So I can access that total amount later in the form. Here is the Javascript piece... <script type="text/java...

Side by Side Execution of .net v1.1 and .net v2.0 (continued)
Hi, Dave wrote a previous post that said: "If you are referring to web applications - each Virtual server must specify the framework to run under.  Both can run side-by-side.. but not under the same virtual server (application pool)" That looks fine, but I wonder: Is it just as easy as going to Administrative Tools --> IIS --> Select the virtual directory --> go to the property's ASP.NET tab and then selecting the ASP.NET version? Is there some important information that I need to know before going into this? Are there going to be ANY issues I should be aware of? T...

Client vs. Server Side AJAX.Net
I am curious to know what the advantages and disadvantages are to using the client side declarative style AJAX controls vs. the server side.  I can't seem to think of too many reasons why I would go to the client side libraries when I can use all the power of ASP.NET (debugging, compiling, controls) and just wrap them in a UpdatePanel.   It also seems kind of counter productive to use the client side libraries because they don't utilize all the cool new developments of ASP.NET.  Am  I missing something?  Do the client AJAX libraries give you m...

I need to get a server side button to run this client side code?
I need to get a server side button to run this client side code when the server button is clicked and then subsequently called by the server. Is it possible? The problem is that the print control is a client side activex. I can call it normally using a client side button but this is no good when I need to print more then one page. Any help would be great. Thanks. The code: function PrintProc(){ var MyPrinter; MyPrinter = new ActiveXObject("ImgXPrint6.ImgXPrint"); MyPrinter.PageFrom = 1; MyPrinter.PageTo = 1; MyPrinter.PageM...

client-side and server-side?
hi, can someone tells me how diff is client side and server side are these two? When I tried to do validation ... I would use Javascript ... which has something like: document.forms[0] ... I think that's client side. My understanding on server side is the "form" ... like u will have <form action=".." method=post> ..... </form> ... so it will send to server ... am I on the right track? Are there any other type of server side examples? Hi, ASP.NET itself is server side. Every piece of code processed is done on a server. What comes out of this is sent ...
