Re: [flexcoders] how to make a class can be iterated by for each/in

[Rishi Tandon]

for each works for collection.
If you have an instance of the collections consist of your class object then u 
can retrieve each item as class object using for each iterator.

Make a pop up window which include the searchable row based on some unique ID

After changing the field value, update the grid data provider with the changed 
row value.

Re: [flexcoders] How to call container's method into component file

Use object oriented best practice.
Mxml I'd nothing but a actionscript class.
If u r initializing  the custom component inside the other component, then u 
can directly access the method or else use the 
Application.application.componentiD.methodName if u are

Re: [flexcoders] Re: Flex alternatives

[Rishi Tandon]

Well Ron, I don't agree with you.
There is a difference between a reality and our own perception.
I have seen a huge demand for flex based solution in 
Education (hmh, piersons)
Finance (j p morgon, boa)
Healthcare (hospira)
Entertainment (directv)
Ecommerce ( eBay ) and the list goes on and on...

If as of today companies decide to change the strategy and port all the 
existing flex based application into HTML 5, then it would take around 5 years 
to do so as HTML 5 is still not mature for web and desktop.
Check the percent of browser which support HTML 5.
N what about desktop apps that are so beautifully created using adobe air.

My personal thought is that some people are trying to take advantage of this 
bad rumours and advertising the dead tools which were existed for years.

Please be patience and watch the change.
N Stop spreading the rumours.

Re: [flexcoders] Copy Support in Adobe Flex 4.6

[Rishi Tandon]

Hi Balinder,

You can create a CUSTOMISED UI control where the selectable is always TRUE. 
Later you can replace all LABEL component with the custom UI control.

You can apply same approach to other component as well.
