QUESTION
So I'm missing something simple or losing my mind. I am trying to reuse a class for multiple pages in a WPF application and bind the properties to the pages that instance it. I've tried setting the DataContext but I'm missing something. I'm loading the StockAnalysis page and then creating instance of the PriceChart class (this is the class for reuse) and I want the properties set in the PriceChart class to be the data to bind to the Stock.xaml.cs page. Even in setting the DataContext it is still looking for the StockAnalysis object. Why?
Stock.xaml.cs
...ANSWER
Answered 2021-Apr-03 at 20:35The problem is that PriceChart
doesn't implement any change notification. With the current code, this is how things will go when StockAnalysis
gets created:
InitializeComponent()
will create theTextBlock
s and the binding. At this point,DataContext
isnull
, so the binding will fail and theTextBlock
stay empty.this.DataContext = PChart
will trigger a binding update (becauseDataContext
is aDependencyProperty
, which means it does support change notification). When the binding updates, it will pull the value ofLastPrice
, which is currently still empty.ShowPriceChart
will set the value ofLastPrice
, but becausePriceChart
doesn't support change notification, the binding doesn't know it needs to update, so theTextBlock
stays empty.
To solve this, I would recomend your PriceChart
implement the INotifyPropertyChanged
interface per this article: How to: Implement Property Change Notification.
(Technically, moving PChart.ShowPriceChart(HistoricalPrice)
before this.DataContext = PChart
would also "solve" the problem, but only if you never need to update the bindings again after initialization.)

I'm trying to do some matrix multiplication in VBA, but I keep getting an error. I've tried to define all the vectors and matrices and do the calculations one stop at a time and it looks like the =MMult function is working correctly, but when using =SumProduct the value returned is 0.
This is my code for this sub (I've left out some formatting):
