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...

Jscript, moving from client-side to server-side (.NET)
Hey all I’m working translating a web-app written in client-side Jscript to run on the server-side as JScript.NET. Without needing to get too specific, I am using Jscript because the original page aggregated raw data to produce statistical results (this was done dynamically based on user 'sort-by' options). The final output is an html report that can be emailed. Because this is currently being done on the client side, as the raw data grows the load-time grows as well (to the point that has almost become unusable). I’m posting here to see if anyone has any experi...

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!

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!

Do i need a .Net framework on the client side?
Hello all, Can anyone tell me if there is a .Net framework needed on the client side when want to run an ASP .Net web application? Or will it generate plain html that only requires an Internet browser? Or is it dependent on the version of ASP.Net (1.0, 1.1, 2.0?)   Thanks!   AlbertWeeda     There is no need for the .NET framework to be on the client computer to access your web applications.ASP.NET Websites renders into HTML so all your client needs is a HTML web browser.  you don't need it. and it generates plain html that only requires an Intern...

Client side .Net Framework version
Dearl All,I have got a windows form embedded into a web application which requires .Net Framework 2.0 on the client end.Now my question is that how can I check if the client has .Net Framework installed or not and also which version it is? Thanks  You can check it through javascript from web app. .NET embeds its version information to IE user agent. So, in IE you can check for .NET with window.navigator.userAgent. For example use the following line in JavaScript to detect .NET 2.0: if (window.navigator.userAgent.indexOf(".NET CLR 2.0") != -1) { // some code goes...

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...

good book for client side scripting in .net?
Anyone come across a good book that concentrates on client side scripting./javascript for asp.net? Or at least a book that has devoted a fair bit of it's pages to this topic? I have the MSPress book, Developing Microsoft® ASP.NET Server Controls and Components. While there are quite a few references to client-side functionality, there is only one dedicated chapter. And that chapter is a mere 20 pages. Bearing in mind that ASP.NET is a server-side technology, I doubt you will find a book that concentrates on its client-side scripting aspect. After all, there's only a few ways...
