I have one Visualforce page and one Visualforce controller. I have different attributes defined in the controller of Visualforce page as shown below

 public boolean firstPanelget;set;
 public boolean secondPanelget;set;
 public boolean thirdPanelget;set;

I also have a separate controller for Visualforce component which is being called inside in visualforce page and i am passing certain list of object in visualforce component from visualforce page.
I have a function in the controller of Visualforce component which is being called when certain sets of operation is required.

Now i want when these operations are being called then attributes(firstPanel,secondPanel,thirdPanel) defined in the parent controller should be set in the component controller without redirecting. How can i accomplish this?

One way is to pass a reference of the page controller into the component like this.

The component has an attribute defined:

<apex:component controller="ComponentController">
 <apex:attribute name="pc" type="PageController" description=""/>
 ...
</apex>

The page sets a value in that attribute via a controller property:

<c:component pc="!controller" .../>

The page controller property is this:

public PageController controller 
 get 
 return this;
 

Then your component markup can reference the page controller properties via pc. For example !pc.firstPanel.

  @Arabinda i dont have controller extensions in my solution. I only have one visualforce page and two visualforce component and 3 apex controllers for each visualforce page and visualforce controller. Visualforce components are included in Visualforce page. There are some logic performed on each visualforce component on the basis of which i need to decide, if i have to show the other visualforce component or not.To show the other component boolean variable has been declared in controller of Visualforce page but i dont have any way on how to access that from componenet controller.

  @MuhammadSheheryarAfsar, that case I can suggest you to use cookies to store some temp variables and manipulate based on your requirement. Give a try for this cookies approach. As in your case, extensions are not linked so this approach can help.
