Yes, that's true. 

When assingning event handlers in MXML, the Flex compiler looks for the
Metadata tags defined in the different classes when compiling a SWF. Due
to the fact that the "cellClick" event is not defined inside the
DataGrid class, the compiler complains.

If you want, you could create a subclass of mx.controls.DataGrid and
define a [Event("cellClick")] in this subclass. Then, when you use your
DataGrid subclass in your MXML code, you'll be able to write 

  <yourNamespace:DataGridSubclass cellClick="doSomething(event)" />

Subject: [flexcoders] Re: 3 problems about datagrid ...

sorry for my neglect...
the way that using   myGrid.addEventListener("cellClick", this)  
works correctly.but it seems that i cannot use the event handler
cellClick directly in the mx:DataGrid tag.
thank you very much!
