run jQuery code from ASP.NET Server-Side

Thu, 04 Jun 2009 12:14:04 GMT

The post is the example of an approach: how you would run some jQuery code from ASP.NET code-behind (server-side). If there is a ScriptManager on the page and the request was Asynchronous, then the JavaScript code needs to be registered with ScriptManager.RegisterClientScriptBlock. If the request is just a simple standard Postback, registering the JavaScript with Page.ClientScript.RegisterClientScriptBlock is the solution.

Rarely used C# Keywords

Sun, 17 May 2009 17:31:02 GMT

When doing code reviews or when working with code that was developed by someone else, once in a while I come across keywords that are rarely used. Some of them are forgotten keywords that are not considered a good practice and hence are not promoted by the community. Some of them could be handy and efficient but they never made it to the limelight.

Code Generation Should be the Nuclear Option

Wed, 06 May 2009 09:16:02 GMT

So let me first just start off by saying: I do not like code generation. In certain cases I think it can help greatly, but many people are far too eager to jump to this solution. I don't think that there is anything particularly evil about the process of generating code, but I do feel like using code generation as a day to day tool is a very bad practice. Code generation should be the tool of last resort when there is no good way to cleanly implement a solution which doesn't require code to be spread out everywhere.

LINQ to XML - XPath

Mon, 10 Nov 2008 17:24:02 GMT

LINQ to SQL may be on it's way out, but LINQ is no way out at all! And don't worry about LINQ to SQL, the ADO.NET Entity Framework is available and guess what it's awesome. Another good usage for LINQ is when you need to query an XML file. When working with LINQ to XML you may remember the old days when you used XPath. But don't worry anymore there is support for XPath on LINQ to XML. There are extension methods for LINQ to XML in the System.Xml.Xpath namespace! Read this blog post if you are interested in an example, and find out if there are any performance issues! Have fun reading!
