Last week I introduced a new screencast on another OData Developer tool. It was about how to use LinqPad to query OData service with C#, LINQ & WCF Data Services Client APIs.

The screencast shows how to use LinqPad to connect to and query OData Services using LINQ and WCF Data Services Client APIs. Showing how LinqPad can be useful as a developer tool to test queries against any OData Service.

I case you missed it, you can watch it on ODataPrimer website. You can also download an HD video (~48Mbs). The package contains 2 videos. One of them is the one hosted and it’s a 10 min video. And the other is ~14 min. I had to trim it to fit into youtube. The 14 min video contains additional stuff in case you are interested.

Before I blog about my presentation and the great experience I had during Cairo CodeCamp days, I want to point to one cool Podcast show about “Women in Technology in the Muslim World” made by Scott Hanselman with Abeer and Lamees 2 Egyptian ladies who work for DashSoft

Abeer is senior system analyst who has over 6 years of experience on this field. Lamees is a software engineer and programmer who is transferring to system analyst role, and she is doing good job about that.

here is the description of this podecast taken from hanselminutes.com:

“Scott's in Egypt today and he had the opportunity to sit down with Lamees and Abeer, two successful women in IT. Lamees is a programmer transitioning to Systems Analysis, and Abeer is a veteran Senior Systems Analyst and Agile Project Manager at Dashsoft. Nearly 50% of the people at Cairo Code Camp are women. What is Egypt doing right to encourage so many women to choose technology as their career?”

Don’t miss this show to know more about women in technology in Muslim world and Egypt in specific. Click here to go to the podcast page.

Silverlight 3 is out, Scott Guthrie Announced that on his blog. As I was started to upgrade my client, I thought it would be useful to search for the SDK and Silverlight 3 VS.NET tools too. Thought to share the following quick links for Silverlight 3

• Silverlight technical resource
• Silverlight 3 for Developers
• Silverlight Tools for Visual Studio.Net 2008 SP1 
• Microsoft® Silverlight™ 3 SDK (Silverlight 3 SDK is installed by Microsoft Silverlight Tools automatically)
• Microsoft Silverlight 3 Offline Documentation

Last month (March 2009)  HOLs for Enterprise Library 4.1 released. Earlier this year there were HOLs released for Validation Application Block 4.1, now a full HOLs is released for the entire Enterprise Library.

Hands-on Labs walk you through the key usage scenarios of the application blocks in in various application contexts. You can practice the labs from start to finish or you can use the starter solutions provided to complete only the labs you want to, in the order you prefer.

• Enterprise Library for .NET Framework 3.5 (v4.1) Hands On Labs

Well, I'm done with this article that show in details how to build on demand loaded details from master data using GridView and CollapsiblePanelExtender control. Read the article.

Earlier this year Matt Berseth posted about Building a Grouping Grid with the ASP.NET 3.5 LinqDataSource and ListView Controls. Then I followed his post with 2 other posts discussing same idea but with different implementation:

• Building a grouping Grid with GridView and ASP.NET AJAX toolkit CollapsiblePanel
• Building a grouping Grid with GridView and JQuery

Later I got few comments about how to implement that using AJAX, in order to display the details data on demand. At that time Dave was demonstrating the usage of jQuery AJAX on his post Using jQuery to consume ASP.NET JSON Web Services. So I came up with another demo to apply on demand loading of details data in my post GridView Grouping Master/Detail Drill Down using AJAX and jQuery.

Again I got few other comments on how to apply same approach, but using ASP.NET AJAX Control Toolkit CollapsiblePanelExtender control. So here I'm going to provide how to do that using CollapsiblePanelExtender and ASP.NET AJAX PageMethods call to apply on demand loading of details from the master data. You can read my article and view Demo here.
