Question

I got this Data Structure:

12 Measurements, each Measurement contains 1-x Cells, each Cell contains 1-x Stations. The Amount of Cells/Stations is the same for each Measurement.

Therefore i have a Measurement, a Cell and a Station Class. Each of these 3 implement the ObservableObject Class.

In my View i create a Itemscontrol for each Measurement to display all Cells of a Measurement. Each Item contains an Itemscontrol to display all the Stations in Textboxes.

Now i need a 13th Measurement in which i calculate the sums from each station across all Measurements. (Station 1 from Cell 1 from all 12 Measurement).

Currently my Viewmodel only contains a Observable Collection with the 12 Basic Measurements.

How can i detect if a Value of a Station-Textbox is changed and what Station has been changed?

Answer 1

You could latch onto the PropertyChanged event for each Station in the ViewModel. This is an event handler in ObservableObject that is triggered whenever a property is modified (part of the INotifyPropertyChanged interface).
