Hi!
I have the tree view with two levels of nodes.
I need to allow to check only second level nodes (i.e. child nodes).
Unfortunatelly I did not find any event fires before node checking.
Is it possible to restrict node checking?
Best regards,
Maxim Ivannikov.
At this time, there is no such built-in capability. OnNodeCheckedChanged is triggered after the checkbox is toggled.
We've checked this and have seen it was technically possible to add an event OnNodeCheckedChanging that is triggered before the change and has an Allow var parameter that could allow to control this. This event will be added & available in the next update.
