Is there a "All Children loaded" event in WPF

Question

I am listening for the loaded event of a Page. That event fires first and then all the children fire their load event. I need an event that fires when ALL the children have loaded. Does that exist?

Answer 1

I hear you. I also am missing an out of the box solution in WPF for this.

Sometimes you want some code to be executed after all the child controls are loaded.

Put this in the constructor of the parent control

Dispatcher.BeginInvoke(DispatcherPriority.Loaded, new Action(() => {code that should be executed after all children are loaded} ));

Helped me a few times till now.

Answer 2

Loaded is the event that fires after all children have been Initialized. There is no AfterLoad event as far as I know. If you can, move the children's logic to the Initialized event, and then Loaded will occur after they have all been initialized.

See MSDN - Object Lifetime Events.

Answer 3

You can also use the event: ContentRendered.
