[CLOSED] Select all tree panel nodes

[PriceRightHTML5team]

I need to add a link "Select All" to the topbar of tree panel and on click of it, it should select all the nodes of treepanel.
How can i do that in MVC.

Please let me know

Hi @PriceRightHTML5team,

First of all you should define

.Mode(SelectionMode.Multi)

for a TreePanel's SelectionModel, because it is Single by default.

Then, to select all the nodes you can call this JavaScript code:

App.TreePanel1.getSelectionModel().selectAll()

Right now my treepanel doesn't have any selection model and i can still select multiple nodes.
Can you please provide me the snippet for setting the selctionmodel for treepanel.

Thanks

If so, then you probably do not need to set up Multi mode. Did you try the selectAll method?

Its not working .It just rolls through all the nodes but keep the selection as it is.
I think the Selection mode is "Single" .How do we set it to Multiple

[Daniil]

If it is Single, you should not be able to select the only node.

OK, to set up Multi mode, you should define this for a TreePanel:

.SelectionModel(Html.X().TreeSelectionModel().Mode(SelectionMode.Multi))
