I have doubt about performance of web site.

Question

I have doubt about performance. I want to develop a responsive website fast execution in asp.net. I use bootstrap for responsive website. SQL and PL/sql for data base. Java script Jquery for validation. asp asp.net for server side 80% interact with data base all drop down list fill from data base what effect happn if I use asp.net server side control and validate that control on client side using JavaScript jQuery and then sent data to server. Or if I use HTML control and validate that control on client side using JavaScript jQuery and then sent data to server usnig JSON who is give me better performance.

No the execution will as it will be with your second option means faster because you are not using server side controls. code may be in server side bt you are using html controls to render the value and Jquery ajax to call those codes so do it no problem and also your website will be fster. and also minify your Js and css files so that your website load will be faster and delete unnessesary scripts and put try catch at every piont and log gthe bugs to log at catch block so that it ll not hamper your website perfomance. Like the answar if helped. Thanks

Hi Adithya You are doing well The performance will depends on no of users will access your application..

Yes of course! And you don't have to believe me. You can try it yourself. I have seen several people do it routinely. Furthermore as @Ramesh says you don't even have to be a developer. Anyone can do it.

Hi Aditya As asp.net server controls use viewstate to store data which may cause performance issue try to avoid as much as you can.One option is to disable view state for the controls or you can compress view state.Other is to avoid use of asp.net server controls as much as possible apart from using data controls. please see the below links https://www.codeproject.com/tips/263166/how-improve-asp-net-performence https://www.codeproject.com/articles/692311/bundling-and-minification-asp-net

However please be generally aware that the client side validation should NEVER EVER be trusted. There are softwares which intercept between form's post and actual sending data to server. Some intelligent users can even enable buttons by pressing F12 and modifying attributes pretty simple stuff actually. They can also modify values of your hidden variables such as currer_user customer_id and easily impersonate as different user. While you may choose to implement client-side validation for performance purpose I highly recommend that you perform server-side validation too!

Hi Aditya Go for second one because using that you ll less communicate to server side postback so page will be not refreshed again nd again and performance will be better. put html control and use jquery ajax and JSON to get the data from serverside code. Mark it if helped. Thanks

Hi Adithya Controls(fields) may be server side or HTML elements it doesn't matter. your validation is a matter. If you validating the elements using javascript or jquery the performace should be fast.. But if you validating the field using asp.net server side the performance will be slow comparing to client side validation because server side validation every time posing the form to server side and validating the fields and return the result.. But the advantage is  the server side script will validate both client side and server side for example if you disable your javascript on browser the server will validate yout fields on server side. If you using only client side validation which means jquery or javascript validation if you disable javascript in your browser it will not validate your fields and it will be post to the server

Rajesh Sahoo sir but i put html control and keep the validation client side as well as server side then execution will be low or not.

Rajesh Sahoo · Answer

Hi if a user is a developer he can edit and enable the server side control too. so u plz do one thing put html control and keep the validation client side as well as server side so that if any one edit the control and edit the value and click any button u can have a server side validation too so it ll not return any data based on edited data and no problem will occure.

Ramesh Palanivel · Answer

Hi Adithya Yes Its possible If a user is developer he can able to edit the data  If example if you disable any input field which has default value  If I am a developer I can able to enable the textbox and can able to change the value.. Server side control is more secure comparing with client side validation

Aditya Nashikkar · Answer

I agree with all of you but which is more secure. using server side controls or client side controls. Nitin Sontakke sir is it posibal by pressing F12 and modifying attributes and then sent or get data after publish website.
