C lient side HTML control : HTML controls are the native elements of browser. These are client side controls which is accessible only in the HTML page and not executed in server side. In this senerio user r equests the page receive the page from the server then display the HTML and process the Javascript.The client side validation can be done using the Javascript or vb script. Client side validation is processed the client side before submitting the form. The advantage of using the client side validation is it reduces the network trafiic since the validation is processed in the client machine itself. so Client side HTML control will improve the performance of the web page. HTML Server Controls : when we can add the attribute runat=server to any HTML control such cases it will be an HTML server control. These controls map directly to html tags and without runat=server it cannot be accessed from code behind. ASP.Net Web Controls: Web Server Controls or ASP.NET controls Web Server Controls are group of controls derived directly from the System.Web.UI.WebControls base class. They are executed on the server side and output HTML sent back to the client browser. If you use a textbox web control in webform what happens when the webform runs is the textbox server control is converted to html control(just like html client side control). This is extra headache when we can have simple html controls in hand.So it is better to not use these web controls where performace is an impotant parameter. Events like load  reder  unload are associated with web controls which are not case for html ones.

Hi Kimi Kalon Following are some basic differences. Server-side code runs on the server. Client-side code runs in the clients-browser. Server side validation can be done on server side controls using server controls. But Client side validation can be done at browser. The control validation can be done at client browser instead of server side validation.Because its additional overhead to the server. For exampleMandatatory fields checking.It can be done at client browser.No need at server side. But the login and password must be validate at server side. The client side validation can be done using the JavaScript or VBScript.
