In doing internet searches trying to learn how to incorporated ajax into web pages generated by the yii framework I noticed that there seems to be a lot of confusion. I worry that too-clever hacks will be broken in upgrades of the framework.
When i had created this functionality then i found some difficulties and not got much idea from wiki and forums. so, i think this will be useful for newbie users and save time of other developers when create related functionality.
I refer Collecting Tabular Input tutorial but not got clear idea for create/update.
The CGridView widget is very useful and customizable, but sometimes you need a little more.
One limit I found is to have only one row for headers; yes, you can write each column header in more than one row, but just inside the single cell.
I was looking instead for the possibility to use more than one row, with different structure one from the others.
This way you can write columns grouping headers, and obtain a nicer view.
