[flexcoders] Re: Datagrid's Itemrenderer - Access to Datagrid

2011-10-27 Thread valdhor 
Even though it looks like you have an answer to your question I'd like to ask 
why you would want that?

It is always a much better practice to inject what you want into the item 
renderer instead of trying to reach back out to the original owner to get it. 
As Item Renderers are recycled this leads to major overhead, the inabilty to 
re-use the item renderer as well as tight coupling.

You may want to reconsider your use case and look at a different way of doing 
it. Telling us what you are trying to achieve may yield a best practices 
approach.

Thanks. I should have mentioned that I did initially that and was
getting the following error:

TypeError: Error #1034: Type Coercion failed: cannot convert
spark.components.gridClasses::GridLayer@260fac29 to

That error looks like you were trying to cast parent instead of owner.

No, I was casting owner and got that error.
i.e. - Datagrid(owner).dataprovider

hmm, don't know what to tell you.  The following works fine:

var myDataProvider:ArrayCollection = DataGrid( owner ).dataProvider as

Try sticking that in override prepare() or set data(), and make sure that data 
isn't null, and I bet you that it'll work.

That worked! I put it in prepare() and was able to get a reference to the 
datagrid. 

Thanks to all for the assistance.
