Implementing support of own child/children in WPF control.

Wed, 20 May 2009 06:15:57 GMT

The best way for use child/children in WPF is customize any control with property for child/children that inherit from Control (for example ContentControl or ItemsControl). Control has wide possibility of customizing through ControlTemplate. But sometime we want to have specific behaviour of child/children (for example if we want to implement MDI container any other specific container). What should you do for implementing this behaviour? I will show major steps in sample of simple custom panel that is inherited from FrameworkElement.

LINQ ElementAt and ElementAtOrDefault

Wed, 13 Aug 2008 23:18:41 GMT

We can use the ElementAt extension method of LINQ to return the element at a specified index (zero based) in a sequence. However the ElementAt extension method would throw the System.ArguementOutOfRangeException when the specified index is a negative value or not less than the size of the sequence. In such a scenario, we can use the ElementAtOrDefault extenion method which would return the default value of a type instead of throwing the System.ArguementOutOfRangeException. Read this article for code example (both in C# and VB.NET) with comments

Linq Framework Design Guidelines - evolve into optimized frameworks

Thu, 31 Jul 2008 00:08:03 GMT

This is from the team that brought you 'Framework Design Guidelines' led by Krzysztof Cwalina, an individual we are not shy to recognize as an amazing mind. Look for this content (as shared here from their internal work) in the next of the book For example : defer execution of query operator implementations. The expected behavior of most of the Query Pattern members is that they simply construct a new object which, upon enumeration, produces the elements of the set which match the query. The evaluation time is, then, at enumeration.

Dynamic Data Access with LINQ

Thu, 03 Jul 2008 02:50:10 GMT

When I talk about LINQ people often ask whether it's possible to have dynamic queries with LINQ. An example of this is presenting the user with a UI that allows them to optionally filter by some criteria or other and sort by some criteria. This was straightforward if you built-up a SQL string in code. The compiled, static nature of LINQ makes this appear difficult at first. They are not and this video and sample application shows you how to accomplish just this.

Create In-line Data Editing with the ASP.NET 3.5 ListView Control

Thu, 22 May 2008 10:17:22 GMT

I am lovin' the total control the ListView control is giving me. This past week a link to Telerik's new RadGrid control was floating around the office - and the general consensus was that the in-line editing capabilities control was pretty cool. And I completely agree - the in-line edit feature is pretty useful. But ... you don't need to buy the RadGrid to create a grid like this. ASP.NET 3.5's ListView control provides excellent out of the box support for scenarios like this.
