In a previous question on Stack Overflow, I had run into an issue with returning an EF query to the DataGridView. Of course I'd run into an issue. However, I added an extension method that still has me baffled since it isn't working. It seems like it should, but for some reason it's not. public static class BindingListEntityExtension { ...

I made a ListBox with your standard smart-control thing, and have it connected to a database. It gets the data I've pre-generated in there via query builder, so when I do this: this.calibrate_swipesTableAdapter.Fill(this.xperdex_crandallDataSet.calibrate_swipes); I get a listbox with my data. THEN, when I add a chunk of data to it, ...
I have a class that implements properties in a specific way, to handle some custom requirements for our business logic system. This "specific way" makes the properties non-operational in the context of data binding. Basically, if I drop an object of our class onto a form, data binding finds nothing on the object, and the property inspec...

But I've currently got the a...

I'm looking for something along these lines: <TextBlock Grid.Column="1" Text="Welcome, {Binding UserName}!" /> This will of course actually display the text "{Binding UserName}" to the user rather than decode it, but I know you can do something like this with ASP.NET, so I'm hoping there's a way to get this to work in WPF. I'...
I am currently programming an ASP .NET FormView. The twist here is that I need to manually set the datasource via "FormView.DataSource = ". I added an ItemTemplate and added some form in the form view but even if the line of code that set the datasource view is called and the FormView.DataBind() is called, I still cannot see the data. I...
