Fun with T4 templates and Dynamic Data

T4 templates have been a pretty popular topic lately. If you have no idea what they are, don’t feel bad, I didn’t either only a couple weeks ago! In a nutshell, it’s a simple template processor that’s built into VS and allows for all kind of cool code

Using User Controls as Page Templates in Dynamic Data

Dynamic Data has the concept of Page Templates, which are pages that live under ~/DynamicData/PageTemplates and are used by default for all tables. Recently a user on the forum asked whether they could use User Controls instead of Pages for those templates.

Creating a ControlBuilder for the page itself

One user on my previous post on ProcessGenerateCode asked how he could associate a ControlBuilder not with a control, but with the page itself. There is in fact a way to do it, and it’s another one of those things that have never really been advertized.

ProcessGeneratedCode: A hidden gem for Control Builder writers

If you’ve ever written any non-trivial ASP.NET control, you’re probably familiar with the concept of a Control Builder.  Basically, it’s a class that you associate with your control and that affects the way your control gets processed at parse time.

A ‘Many To Many’ field template for Dynamic Data

Unlike Linq To Sql, Entity Framework directly supports Many to Many relationships.  I’ll first describe what this support means. In the Northwind sample database, you have Employees, Territories and EmployeeTerritories tables.  EmployeeTerritories

Why posting questions to the forums beats private emails

While most of the Q&A about ASP.NET happens in the forums , I also receive a number of direct questions from users (and so do other people on the team).  In most cases, I try to convince the sender to post to the forums instead, and there are

Using ASP.NET Dynamic Data with ObjectDataSource

Support for LINQ based O/R mappers Out of the box, ASP.NET Dynamic Data has support for both Linq To Sql and Entity Framework.  In addition, it has a provider model which allows additional O/R mappers to be supported.  For instance, we have

ASP.NET Dynamic Data on CodePlex

Today, ASP.NET Dynamic Data moved from its current home on Code Gallery to its new home on CodePlex .  Note that this is part of a general ASP.NET CodePlex project, so you'll see other features mentioned in there, like MVC and AJAX.  This doesn't

Dynamic Data and the Associated Metadata Class

If you've used Dynamic Data or watched some demos, you may have been puzzled by the way metadata is associated with database fields. Instead of being placed directly on the partial Entity class (e.g. Product), it needs to go on a different class which

Understanding foreign keys and relationship columns in Dynamic Data

Suppose you're dealing with a table that has a foreign key relationship with another table.  To take the canonical example, let's say we're looking at the Northwind Products table, which has a foreign key into the Categories table.  What this

Sample: Dynamic Data and attribute based permissions

Dynamic Data, AJAX and JavaScript errors

The default Dynamic Data application uses AJAX partial rendering (using an UpdatePanel ), which make browser post backs feel smoother.  One downside is that it can also make it harder to diagnose some error conditions. Specifically, while using your

Clearing some confusion about Dynamic Data and VS SP1 Beta

Today, we released Visual Studio 2008 and .NET FX 3.5 SP1 Beta, which include the new ASP.NET Dynamic Data .  The part that gets a little bit confusing is that the Dynamic Data bits that come with the brand new Beta are actually older than Preview
