Hi Gary,
Thanks for your reply,
I just need a dynamic mechanism that creates this
{parent:'root1',col1:100,date:myObject[0],col2:33},
{parent:'root1',col1:5,date:myObject[1],col2:21},
{parent:'root2',col1:11,date:myObject[2],col2:5}
dynamically.
I have the columns array and all the data in a list of arrays(look at
the previous posts i sent)
In short, I need to create the dataprovider dynamically, some kind of
routine that accumulate columnName and append ":" and objectValue
with comma etc.
Thanks
