During my “Business oriented Silverlight 2 application” talk at DevTeach conference (december 2008) I used Visual Studio 2008 and Expression Blend to build an application that retrieves SQL server data (Beers!) through an Entity Framework model and exposes it to a Silverlight client via a WCF service and LINQ queries. I did some design and animation, added a ComboBox and DataGrid to display data and asynchronously update the model as users edit it. Then I showed how to use local cache on the client to optimize network traffic and finally applyed some Style to shape the UI.

I had only 2 slides in my ppt deck, and here is my funny slide #2:

I coded all that live on stage in 60 min without any errors!

As promised here is the source code of the application I built live:

Guess what’s inside my Zune bag…

…my iPhone!
The original Zune suede bag is way too small to fit the Zune but I found the perfect fit now!

Following my first post on ASP.NET Dynamic Data, I want to show you that you can customize existing fields used by Dynamic Data very easily.

With the Northwind db, here is the generated edit screen for the Employees table:

 

We could make this default user experience a lot better by changing the date input, why not add some AJAX here ?

Template fields used by Dynamic Data are stored in DynamicData/FieldTemplates folder as simple user controls:

You can see that there is a DateTime_Edit.ascx control, open it and add an Image for the calendar icon and a CalendarExtender from the ASP.NET AJAX Control Toolkit.

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajax" %>
<asp:TextBox ID="TextBox1" runat="server" CssClass="droplist" Text='<%# FieldValueEditString %>' Columns="20" /> 
<asp:Image ID="imgCalendar" runat="server" ImageUrl="~/DynamicData/Content/Images/calendar.png" />
<ajax:CalendarExtender runat="server" TargetControlID="TextBox1" PopupButtonID="imgCalendar" />


Now you get:

The calendar looks weird due to some CSS applied to the DetailsView. A quick workaround is to remove the CssClass attribute from the DetailsView1 control in DynamicData/PageTemplates/Edit.aspx :

Doing that (or fixing the CSS in Site.css file) will make the calendar looks good:

Note that the field is still fully functional without adding code, in a next post I will show how to create a new template field.
