In our .Net 1.1 days we used to check whether a string object contains a specified string(text) using IndexOf method.
Here is the typical code to check the existence of a string in an string object.
//Sample code

Developers were always looking forward to the inclusion of Nullable types in C#. I love the way it's been implemented using generics. Before we go in to the specifics of Nullable types; let's look at what is a Nullable type and it's usage.

Memory allocation can be avoided by using string.Empty.

In the year 2005 we published an article about creating master-detail GridView control. jQuery was not a first class citizen during that time and most of the work was performed by either plain old vanilla JavaScript or the server side code. With the advent of jQuery we can now create cool master-detail effects easily in less time and less code. This article explains how to spice up master-detail using jQuery.

Sometimes we need create many reports in multiple threads simultaneously. This may be the development of a web service, or output information from an existing multithreaded application in a certain document format (PDF as example).
I noted that FastReport VCL library is a better solution for document generation in multiple formats. This component library is easy to use and has a convenient report designer which allows you to easily connect to different data sources, among which may be internal application data - arrays, sets of parameters, etc.
Traditional use of FastReport does not give any difficulties, but now we have to use this report generator in a multithreaded application. The output file format will be PDF.

I was sorry that the Autocomplete filter from the old Futures project was not added to Dynamic Data 4. So I thought I would do it, and here it is. I also thought I would make it work with the Entity Framework as well.

Ajax libraries have simplified developer's life by providing clean & easy-to-use API. Their usage is so simple that we developers over use it, without realizing the performance impacts. In this article, I would like to explain a few scenarios in which Ajax can be an overkill for your web apps.

I wrote unit tests for my ASP.NET MVC application that uses some jQuery AJAX-components. These components load data from server in JSON format. I needed to write tests for these methods to make sure that correct data is returned to client. In this posting I will show you how to use dynamic type to test JSON-based action results and therefore avoid creating DTO classes.

When trying to build the right data structure in Orchard to contain a view model to which multiple entities blindly contribute, it became obvious pretty fast that using a dynamic structure of sorts was a must. What we needed was a hierarchical structure: a page can have a list of blog posts and a few widgets, each blog post is the composition of a number of parts such as comments, comments have authors, which can have avatars, ratings, etc. That gets us to the second requirement, which is that multiple entities that don’t know about each other must contribute to building that object graph. We don’t know the shape of the graph in advance and every node you build is susceptible to being expanded with new nodes. The problem is that C# static types...( read more)  |

In the first part of this post , I explained what requirements we have for the view models in Orchard and why we think dynamic is a good fit for such an object model. This time, we’re going to look at Louis ’ Clay library and how you can use it to create object graphs and consume them. But before we do that, I want to address a couple of questions. 1. If we use dynamic, aren’t we losing IntelliSense and compile-time checking and all the good things that come with statically-typed languages? And is C# becoming overloaded with concepts, and trying to be good at everything but becoming good at nothing? Hush, hush, everything is going to be all right. Relax. Now think of all the XML/DOM styles of APIs that you know in .NET (or Java for that matter...( read more)  |

This is the twenty-sixth in a series of blog posts I’m doing on the VS 2010 and .NET 4 release. Today’s blog post covers some useful debugging tips that you can use with Visual Studio. My friend Scott Cate (who has blogged dozens of great VS tips and tricks here ) recently highlighted these to me as good tips that most developers using Visual Studio don’t seem to know about (even though most have been in the product for awhile). Hopefully this post will help you discover them if you aren’t already taking advantage of them. They are all easy to learn, and can help save you a bunch of time. Run to Cursor (Ctrl + F10) Often I see people debugging applications by hitting a breakpoint early in their application, and then repeatedly...( read more)  |
