I have an verticalFieldManager as shown in fig. and in this manager I have some label field and a button field.
Now on the click of the manager I have to go to other screen and on the click of that arrow button I have to show the details.
Please give me some idea how can I do that.

You need to have the ButtonField consume the click event. The simple way to do this is with a style bit passed to the constructor: ButtonField.CONSUME_CLICK
