Select by condition in TreeGrid

Smart GWT Technical Q&A
1

Hello

Help me please. I am using TreeGrid.
I am writing

        g.setSelectionAppearance(SelectionAppearance.CHECKBOX);
        g.setSelectionType(SelectionStyle.SIMPLE);

And at the begining of the each row appear checkboxes.
But, i need to make some rows ‘unselectable’. So i need ability to show checkboxes on some rows, and do not show on others. How can i do it?

You can use the canSelectProperty on individual nodes.

There is no method setCanSelect in the TreeNode class, what did you mean?

Use TreeNode.setAttribute(“canSelect”, false); The actual attribute “canSelect” itself that is used for determining if a record / node can be selected can be controlled using the ListGrid.setRecordCanSelectProperty(..) API.
