Multi value converter in databinding



Posted by: MarkWPF
C, Databinding, WPF, XAML

Here's a nifty little trick that I recently discovered. When you need to calculate the result of two properties and display it, you can do it via a Converter class. You may want to do it, like me, if you couldn't update the business objects, or didn't want to. How do you do it? Your...

Databinding with Linq with automatic updates



Posted by: MarkWPF
C, Databinding, SQL, WPF

How do you databind to an EntitySet retreived from a Linq query, via Linq to Sql or Linq to Entities for example? Well it is very easy to actually bind to it, you simply connect it up using normal Xaml syntax. But what if you want to have updates automatically relected in the UI? That's...

Combobox – reference not being set



Posted by: MarkWPF
C, Databinding, WPF

I've come across this strange little quoible. It's possibly just just the way I've been trying to use it, but it still seems odd to me If you have a ComboBox which you are databinding to using an object, like: <ComboBox SelectedItem="{Binding Path=Market}" /> Where Market is a...

If you want to, for example, to override a control template for a control in WPF, it is quite easy and very powerful.

ListView – is it really too slow?



Posted by: MarkWPF
C, ListView, WPF

I have seen a number of blog entries along the lines of 'ListView is too slow', or 'WPF is too slow', or the worst one of all 'ListView has performance issues'. Obviously none of them mention any details, nor elaborate on what issues there might be - sounds a bitĀ like an old project managerĀ of...

ListBox – the forgotten control



Posted by: MarkWPF
C, Databinding, WPF

How did that happen? I personally think it happened because when we were all looking at WPF to begin with (in CTP days), it was very obvious that there was no Grid. Then, because of that people noticed that the ListView control had the option to specify a grid version as one of it's views. That...

Localisation



Posted by: MarkWPF
C, WPF

Let me firstly describe the localisation support in WPF - absolute pants
For those people who might read this who don't understand the local London, UK colloquial term pants - it simply means very bad.

Essentially you get the same localisation engine as v2.0 Windows Forms without...
