Use a markupcontainer and add both components to it. Then add container
as cell.

CheckBoxPanel & Page class have correspoding html file

[Newgro]

You add a single column to your tree. But you overlay the default cell
component by the checkboxpanel.
So you don't get all the stuff from parent component (Like link and node
icon etc).
Check TreeTable.TreeFragment for details.

You have two opportunities:
1. If you want to add your checkbox directly beside the tree structure
components you have to copy the code from the treetable class
2. If you only want the treestructure in one column (with a link label)
and the combobox in the second column then you have to add
another column on which you don't overwrite newCell (see below)

Hello again,

My requirement is exactly related to the point 1. you specified

1. If you want to add your checkbox directly beside the tree structure
components you have to copy the code from the treetable class


If you could elaborate a bit, it will be very much useful to try out.

Hello again,

The links and nodes are added in the TreeFragment class. But the TreeFragment is a private inner class in Treetable, could you tell how to use the TreeFragment to acheive this functionality
