About <apex:param> ?



What is the use of <apex:parm>? 


Thanks in advance. 




<apex:param> tag is used to pass the value from visualforce page to controller.

For Example:
<apex:param name="val" value"parametervalue"/>

you can access this value from your controller using below line.

<apex:param assignTo="controlllervariable" value"parametervalue"/>

you can also use assingTo attribute to set the value in controller variable.
