Question

We are using treepanel in our application. It is working fine. But if we select the parent node, then the child nodes in that parent are not selected. How do we select the child nodes when we select the parent node?

Is there any method available in ExtJS4?

Answer 1

You have to respond on the itemclick event and select all nodes below the clicked node. If you only want to select the immediate children of the clicked node, exchange cascadeBy() with eachChild().

tree.on("itemclick", function(view, record) {
    var selModel = tree.getSelectionModel();
    record.cascadeBy(function(r) {
        selModel.select(r, true);
    });
});
