Need some help on grid panel control

[Mr.Techno]

Hi friends,
i have to show data in a gridpanel in expand and collapse mode. In page load i bind data to gridpanel, when the user clicks on row of the grid i want to show another gridpanel in it.. for example... the data is like this...

categoryname property1 property2 property3(these are grid headers)
------------------------------------------------------------------------------------------
+ cat1                124            234        34                                                
+ cat2                34              3           56

each category have sub category with same property names.. when the user clicks on the "+" icon or row, the category should expand and get data from database and should look like this

categoryname property1 property2 property3
-------------------------------------------------------
- cat1                124            234        34
   +subcat1         23             34          12
   +sbucat2         111            200        22                                                
+ cat2                34              3           56

is it possible to achieve this with ext.net. I saw row expander examples but unable to solve my problem.. can anyone provide some example on this?

please help me... thank you.

Hi dx7, thanks for your reply.

This is how exactly i want to get...
can you tell me how to achieve the same features with store or datatable? Because i get the categories and its properties in a datatable. when the user clicks on the category then i want to get the subcategories with properties info(again datatable here) and bind it to the node..

can you give me example how can i do it...

thank you...
