Expend a specific node in TreeGrid

[zolotoy]

I am trying to programmatically open first node in the treegrid after having all nodes collapsed.
Here is my code.
In directive as the last line in Link finction:

Code:

scope.assetTree = $(elem);

In controller when data has been received:

Code:

$scope.assetTree.treegrid('expand', 1);

Nothing happens, the first node is not expended.

Please help.

Thanks

Check if the id of your first node is really 1...

Console shows it as "1". I tried it too, same.

Do you test as String, say '1'...

I tried both a number and a string. The result is very consistent - nothing.
