applicationComplete is an event, dataProvider is a property.
I don't think you can have it so dataProvider calls a method.
If this post answers your question or helps, please mark it as such.
Can you please explain how to invoke a remote method to populate data in ComboBox? so far I know to get data I'm using applicationComplete which is working fine...but my problem is that I have DataGrid and ComboBox both needs to invoke different methods. In applicationComplete I'm calling a method which fills data for DataGrid...which is working fine..
But I'm stuck to call one more method which populates ComboBox, can you please send me some sample where ComboBox invokes remote method which populates data??
