GridView and Invalid CurrentPageIndex Value Exception
There are many developers who have faced the page index problems using GridView. Specially, if GridView supports deleting. Also one may face page index going out of range when there are multiple users managing same data. Here is my little advice about how to avoid page index problems when using GridView.

C# and Partial Classes
.Net 2.0 provided us with new feature called partial classes. Using partial classes we can use multiple files to keep the code of same class. Yes - we can put some methods to one file and the others to another file. Although partial classes may be extremely useful they can be also used to ruin system's technical design if developers don't know what happens behind the compiler.

SharePoint on Vista
Famous SharePoint features developing company Bamboo Solutions has created installer for Windows SharePoint Services 3.0 SP1 that install WSS3.0 on Windows Vista.

C# and anonymous types
One cool feature of C# 3.0 is support of anonymous types. Let's suppose we have to create some data structure and we need this structure in one place in one method. This far we had to create a new private class or structure. With anonymous types we don't have to define new type - we can create it on the run.

C# and var keyword
C# 3.0 introduced us new language feature: type inference using keyword var. Some guys think that var in C# is same thing as var in PHP. That's wrong - var keyword in C# is totally different thing and it doesn't mean that C# has now support for type changing class attributes. Let's prove it.

Behind the Compiler
"What will happen behind compiler?" is my favourite questsion when dealing with technical design and coding. There are many cool and powerful things we can use to be more productive, faster and better. We have automatic properties, extension methods, partial classes, generics and so on. If we don't know what they are and how these things are handled by compiler we may face serious troubles later.

Using parent page properties in user control
There may be situations when we need to use parent page properties from user control. I know, this situations is a warning sign - there's something wrong with UI structure if user controls should know their parents. So, how to get correct reference to parent page so we can use also custom properties defined there?
