difference between commandButton and pageBlockButton

I want to know difference between  commandButton and pageBlockButton for interview purpose.

Please suggest some important difference not the salesforce's definition.


Thanks You!

Hi SKT,

commond button is used to execute actions which we write in controller.
pageblockbutton is set of buttons like save,cancel which looks like standard buttons.

<apex:pageblockbutton> is only about styling -> you have to put <apex:commandbutton> inside this section and then it have styling like standard button on page layouts(is on the top and bottom of page, centered)

And commond button may not be required to be placed in pageblock, but pageblockbuttons should be.

Thanks Prad.

Does it mean that pageblockbutton also calls the "save","cancel" in controller?

No, <apex:pageBlockButtons> is only another `block`, where you can hide your command buttons -> and then, they are automatically styled like standard buttons..as I wrote above..

No SKT,

It is only for styling.

So if we want to style our commandbuttons we must write them inside  <apex:pageBlockButtons>. Ths is the only use of  pageBlockButtons.

These will not call constructor methods.

Did I get it correctly?

Not limited to that, using pageblockbuttons we can also do some actions like onkeypress, onkeydown, onmousedown/up/move/over and so on, which we declare in controller.
