Can anyone explain about onClick and onClientClick, I also want to know the differences between them.

One more doubt is, Is onClick Clientside event or Server side event?
Updated 8-Jul-20 18:57pm

1.On Click Event sends the request to the server and in response performs the action.
2. On Client Click is very similar to onclick function which we use to write in Javascript... that is it executes the statements in the client side with out sending it to the server

OnClick will work on server side , OnClientClick will execute on client side before control passed to server.
If the client side code returns TRUE then it will go to server.
Generally programmers use onClientClick to validate the controls like textbox,etc.
The Button/LinkButton/ImageButton controls in 2.0 and more have a OnClientClick property. This is basically a shortcut for Attributes["onclick"] allowing you to do:

Button1.OnClientClick = "alert('foo');";
