Could any one explain the following queries about "View State".  I have gone through the standard documents for it but I did not get the following queries.

I am new to this tech and I am going through it by self practice. So I did not get it clearly.

here are my queries-

1- What is View State?

2- Why we need "View State"?

3- What are the benifits of "View State"?

4- Based on our design of VF page and Apex class\controller how we can deside this will come in "View State" or not?

Thanks for your valuable suggestions.

It will help me a lot to know 'View State" in the real-time not based on docs.

Thanks,

I need to implement one functionality in opportunity object. Please find below mentioned functionality.

Scenario-

If "Stage" for opportunity is "propecting" i need to display  "1 Green Flag" ,

If  "Stage" for opportunity is "Closed-Won" I need to display  "2 Red Flags",

if "Stage"  for opportunity is "Closed-Lost"  I need to display "3 yellow Flags"

And

if  "Stage for ooportunity is " Closed-Won" the Opportunity must be "non-editable".

Could anyone please help me how to implement it.

Thanks for your all valuable help.

Thanks,
