asp.net 3.5
DESCRIPTION
TRANSCRIPT
Marc Ziss Z Consulting
Code Name 'Oryx' Web application scaffolding
Easy to dynamically display pages based on the data model of the underlying database
Easy to edit data for admin appsHelps in prototyping systems quicklyOut of the box simple to use or can be very
customized
Uses LINQ to SQL to build a Data model.Uses DynamicData Controls to build editable
screens.Builds in Paging, Sorting, Filtering, and
Validation automatically.Dynamic Data fields for rendering individual
data types.Allows a great deal of customization.
ASP.NET 3.5 Extensions CTP
(http://www.asp.net/Downloads/3.5-extensions)
Visual Studio 2008
Subsonic (free)Django (free but Python)ASP RunnerIron Speed Designer
ASP.NET 3.5 Extensions CTP has a lot in itASP.NET Dynamic DataADO.NET Data Services (formerly codename
Astoria)ASP.NET Model View Controller ApplicationsASP.NET AJAX
Managing Browser History Using Server Controls ASP.NET Silverlight contolsADO.NET Entity Framework
ListTemplate.aspx - Grid to edit inline or call from a link to a detail page.
DetailsTemplate.aspx – Edit one record on a page.
ListDetailsTemplate – Both a grid and an a detail editor (default).
Same Routing engine as MVC.
DynamicGridView
DynamicDetailsView
DynamicFormView
DynamicListView
DynamicField - Automatically knows what mode Dynamic view is in (Edit, Item, Insert) for use with DynamicGridView DynamicDetailsView
DynamicControl, DynamicEditControl, and DynamicInsertControl – Dynamic fields to be used with templated view controls Template columns in a DynamicGridView DynamicFormViewDynamicListView
Customizations as easy as making a new partial class.
Allows unique behavior for a particular table
DisplayFormat - formats for currency, dates, etc…
DisplayColumn – Allows a text column other than the 2nd column in the fk to describe the ID
[Range("UnitsInStock",10,50, ErrorMessage="Must be between {1} and {2}")]
[Required("ContactName", ErrorMessage = "Contact name is required.")]
[Regex(“ssn", "[0-9][a-z][0-9]", ErrorMessage = "Needs to be formatted as 'number letter number'")]
LINQ to SQL classes are generated with hooks for events that are normally not implemented
Lightweight event notification
New feature new to .NET 3.5 called partial methods
Like partial classes, but used to extend methods that may or may not be implemented in class instance (can be seen in Northwind.designer.cs)
By default Dynamic Data Fields try to match the rendering of a control with one of the built in Control Templates:Boolean.ascxBoolean_Edit.ascxDateTime.ascxDateTime_Edit.ascxInteger_Edit.ascxDecimal_Edit.ascxMany More
Simple .ascx filesWhen code is modified all controls behavior
will be affected globally.Can perform global validation here as wellExample Calendar
[RenderHint] enables you to build a custom control that can be explicitly linked to a field.
Simple as validationBecause it is a user control there can be
multiple controls that can speak to each other.Can use Ajax Toolkit to use helpful extenders
right out of the boxCustomized controls work regardless of which
view is beieng used (i.e. DynamicGridView, DynamicListView, etc…)
Don’t have to work with a Page Template we can build stand alone pages that use dynamic data
Requires a little more work.Need to make some manual changes…for now
Newest template based control has dynamic counterpart.
Has the benefits of a GridView, but allows full control of rendering.
Interesting wizards to help setup the template in interesting ways.
