WPF Data Binding Not Refreshing When Bound to Static Object

Posted on August 1, 2008

And the WPF Data Binding wierdness/frustration continues ...I have a DataTemplate where DataType is defined. (In other words, WPF magic figures out when to use the template based on the type that is being bound). The Template includes a ComboBox which is bound to a static object in my UserControl class. The SelectedItem of the combobox is bound to a property of the DataTemplate's type (which, in this case, is a linq entity object).It looks ...

Type casting your User Control Class in ASP .Net 2.0+

Posted on July 31, 2008

I ran into a little bit of a strange issue today:I created a User Control that was being used multiple times on a page.

DBNull is my Nemisis

Despite what I told interviewers when looking for a new job last summer, I definitely prefer C# over Java. Having learned to program mostly in C++ with all it's (dangerous) flexibility, the fact that Java did not implicitly convert primitives to their object counter-parts (i.e. double and Double) - not to mention the endlessly long names - filled me with endless internal rage. Endless. My rage was especially acute when dealing with Java web ...
