Do you really want a DataGrid in each row of the tree or just multiple text
widgets in a row. The DG will normally show a header for the columns and
its own scrollbars.
I want to render datagrid instead of leaf nodes. the grid should contain the details of all leaf nodes for that brnach node. I do want to have a column header as well. I have created a TreeItemRenderer component. But it is rendered for eac leaf node which I dont want. Please help me.
