I don't think you can specify multiple custom controllers that way - the docs say that the controller attribute takes one class name.

 

You can, however, use extensions with custom controllers in the same way as standard controllers, e.g.

 

<apex:page controller="MyCtrl" extensions="ext1, ext2">

 

Your extensions will need to have constructors that take an instance of the custom controller as a parameter.

It is possible to use more than one controller class. You can use "Extensions"

 

This link contains an example of how to use Extensions with Standard controller. You can use it in a similar way with an ordinary Controller as well. [You cannot use a controller if you are using a standard controller and vice versa]

 

Hope this helps!

Hi Shruti,

 

In the exmample, a standard controller is used. But i dont want to use any standard Controller. Can i use controller instead of standardController? I have also tried that one, But in that case, the extension Controller class Constructor takes the Controller class object as its parameter. I dont need that one. My two controller classes are independent with each other.

 

If there is  any other solution, please let me know

Thanks Bub,

 

You are absolutely right. Thanks a lot for your suggestion.

 

If i am not going to use the constuctor of extension controller having parameter as controller class instance, then it is not possibel to achieve that one.

 

So i used one controller class, and from that controller , another class method(i.e the 2nd controller) is called. 

After that my code is working perfectly..

 

Thanks all for your help
