Nearly 6 months ago a wrote a post showing how you can use ASP.NET 3.5's new ListView and LinqDataSource controls to create a pretty sweet looking grouping grid.  Well I recently created a few additional skins for my original grid that I thought I would share.  You can follow the link to the demo site to see them in action and if you are interested in learning more you should read my original post and then download the sample site and step through some of the code. All of the themes use exactly the same markup.  All images (including expand/collapse icons, sorting icon and pager icons) are controlled via CSS.  My original post used ImageButtons, but I replaced these with LinkButtons.  This seems to be working out pretty well - I can use the CommandName and CommandArgumnet properties to hook into some the ListView and DataPager's advanced features, but I...

I took a break from my recent Silverlight explorations to work on a new datagrid skin.  I thought the skin turned out fairly well so I figured I would pass it along just in case anyone else could find a use for it.  Like some of my other skins, it makes use of ASP.NET 3.5's ListView, DataPager and LinqDataSource controls.  Here is the run down of the features ...    VS 2008 style border blue border  Vimeo-ish style data pager Row hover effects (except for IE6) Sort icons Live Demo (IE6, IE7, FF, Opera) | Download VS 2008 Style Border To create the border, I used a variation of the rounded corners technique Josh outlines here.  Below is the markup.  It is pretty much just a handful of DIV elements that are used for holding the images.  If you are thinking about using this technique, you should check out Josh's site...

This past week I finally set aside some time to take a look at Silverlight.  I started with ScottGu's digg demo application and continued on to silverlight.net to check out what some of the early adopters have already built.  I didn't get too far before I bumped into a control on the Silverlight showcase homepage that thought was pretty interesting.  The control is a datagrid of sorts that allows you to filter the contents of the grid using a tag cloud.  So I took a crack at creating a similar looking grid using ASP.NET 3.5 (the screen shot is below). Notes: The icon images used in this sample are transparent PNG's, so the demo page looks a little goofy in IE6.

LinkedIn has a nice looking address book widget that displays all of your connections partitioned by last name.  To the left of the contact listing is an index that allows you to jump right to a section.  This control isn't overly fancy, but I was curious what HTML/CSS/JavaScript was used to create it.  So I took it apart using the IE Developer Toolbar and rebuilt it using ASP.NET 3.5 - making use primarily of LINQ to XML, the LinqDataSource and a couple of ListView's.  Feel free to browse the source code by following the download link.  And, of course I recommend checking out the live demo as well.  If you are interested in how I created the sample, a quick description of the implementation details can be found just below the screen shot.  And the best part - excluding the CSS, only 115 lines of markup/code are required to build...

Last November Josh Stodola wrote a detailed post discussing how great looking fluid-width rounded corners can easily be created using Paint.NET, a handful of DIV tags and a small amount of CSS.  The basic technique Josh outlines isn't new, but he does a great job walking through the steps with just the right amount of detail.  I remember reading the article sometime after I struggled through creating an AjaxControlToolkit control based on NiftyCorners (being completely uncreative, I called my custom extender control the NiftyCornersExtender) and I found it very interesting.  I recently went back through and re-read Josh's article this past week and went through his tutorial again. It turns out this was great timing - I am working on a project where the client has requested a sleek, soft and simple interface - those were their exact words.  So I used Josh's tutorial to frame a couple of my...

Lately, I have been playing around with ASP.NET's new LinqDataSource.  Most of my data resides in a SQL Server database, so I always configure the LinqDataSource to work with the LINQ to SQL DataContext and Entity objects.  These components are still pretty new to be, so I am still kind of in awe at how it all works together so seamlessly.  I guess maybe I am a little paranoid, but I don't like that using LINQ to SQL seems like magic.  Sooner or later something is not going to work, and I am going to have to figure out why that is.  Maybe it's a performance problem, maybe it's a data integrity issue, but sooner or later I am going to have to understand (at least a little bit) about how LINQ to SQL works so I can effectively debug my problem.  I found that displaying the SQL statements the...

One of the projects I am working on is on the verge of failure.  For a while now the writing has been on wall, but this was the week that everyone finally realized it.  Its a rotten feeling and I hate it.  So to cheer myself up and to keep the creative juices flowing I thought I would play around a little bit with ASP.NET 3.5's new ListView, DataPager and LinqDataSource controls.  A while back, I came across a really nice looking data grid that I wanted to create a ListView skin for.  Besides the nice soft blue color scheme, I liked the data grid's sorting icons, all caps headers, alternating row styles as well as the simple text-based data pager.  So I used the ListView and DataPager controls to build the visual elements of the data grid and used the LinqDataSource to source the grids data.  I have written...

I haven't played too much with ASP.NET 3.5's new LinqDataSource control yet - so I figured it was about time I did a little research and checked it out.  Typically, I like to document my research by creating a small prototype application focused on a handful of the new features that I am investigating.  I find building a reference application is helpful because it tends to drive out some of those nasty implementation details that somehow remain hidden if I just browse the documentation or read a reference book.  So for a recent research project, I decided I would look into the LinqDataSource's control GroupBy and OrderGroupBy attributes to see if they could be used to help me build a grid that supports grouping.  Below is the final screen shot for my reference application.  The grid shows the rows in the Northwind Orders table - grouped by the customer that...
