问题 I have a popup window and I want to run a function from in the parent window.

问题 This one has me stumped. We have a custom ItemsControl which uses both custom containers as well as a custom panel as its ItemsHost. Now the panel has some metrics that the containers need for rendering purposes.

I have also confirmed this exact thing using Snoop on a standard ListBox so this isn't exclusive to our code, but apparently

As in the dataset example below, Record with Name - Tiger Nixon have two child records, which
