[meticoolus]

HI All,
I have a requirement wherein i need to create flex components like check
boxes, radio buttons or datagrid dynamically based on the values and type of
the components retrieved from the db.
What would be the best approach to achieve this.Pls help me with links and
sample codes.

To create a dynamic Flex component, you can declare that component, instantiate it, then set it's properties at run-time.
Using method addChild , it will allow the add of this new component to an existing Flex UIComponent.
Here an example on how to add new button:

var buttonNew:Button;
buttonNew = new Button; //create the button
buttonNew.label = "Create Canvas Control"; //set some properties
buttonNew.addEventListener("click",addCanvas); //set an event listener
this.addChild(buttonNew); //add the button to the DisplayList

If you go inside more generic, you can use a switch/case statement in action script,
If the component to add, is a button, use the above code, for other types, statement will be different.
An other solution is to think on is RSL(runtime shared libraries), here is an example following this link:
