[CLOSED] Keep selection after reloading a node

[RCN]

[Daniil]

Hi,

There is no such built-in functionality. Though, I think it should not be a problem to implement it.

I would save the selected nodes before reloading and restore them after.

Ok Danill, please mark it as resolved. if you want i can post my solution to achieve it

[Daniil]

Sure, it would be good and can help someone (us as well) on the forums in the future. So, if you wish to share, it would be appreciated.

Thanks for sharing, looks good.

Here is another approach.

Example

var reloadRoot = function () {
var tree = App.TreePanel2,
store = tree.getStore(),
options = {
node : tree.getRootNode()
},
sm = tree.getSelectionModel(),
selectedId;

if (sm.hasSelection()) {
selectedId = sm.getSelection()[0].getId();
Ext.apply(options, {
callback : function () {
var node = this.store.getNodeById(this.idToSelect);

if (node) {
this.sm.select(node);
}
},
scope : {
store : store,
sm : sm,
idToSelect : selectedId
}
});
}

store.load(options);
};
