Customizing pages with Asp.Net Dynamic Data Domain Service Web Applications?

Posted By:      Posted Date: August 30, 2010    Points: 0   Category :ASP.Net
Hola, It used to be so easy creating new folder under CustomPages with the (Entity/Table name) and copying on it all base default PageTemplates (Details, Insert, Edit, List and ListDetails) and you will get access to those pages only for the specific table (this was the default automatic behavior of the Dynamic Data framework) When it comes to be using Asp.Net Dynamic Data Domain Service Web Applications it seems that we need to learn a new way of doing this because it is just simply different and you got a lot of errors when compiling your application if you do this the old way? What might be the new way, uh? HOW DO WE DO THIS NOW ... I MEAN ... CREATING DEFAULT CUSTOM PAGES FOR SPECIFIC TABLES (Details, Insert, Edit, List and ListDetails) with Asp.Net Dynamic Data Domain Service Web Applications? The problem arises when the definition for your newly created classes is absent from the automatically generated code when you created your domain service !!!!! . If you simply copy the PageTemplates as they are, you got a duplicated error message because the new .designer file (automatically generated) conains the definition of the class you are copying (not the newer one) so even if you rename your .aspx file the result is not what you would normally expect (the .designer class is not regenerated after renaming). The .designer file keeps the domain service definition and if y

Cannot INSERT record using Asp.Net Dynamic Data Domain Service Web Applications

 Hi, I am working on a 'Asp.Net Dynamic Data Domain Service Web Application' project using just 2 tables, FAQ_Categories and FAQs. The FAQs table has a foreign key to the FAQ_Categories. The steps are straight forward. Add a new project (Asp.Net Dynamic Data Domain Service Web Applications) Add folders Model ( for Linq2Sql datacontext), Domain (for the Domain Services class) Add Linq2Slql and add the 2 tables to the designer. Build the project. Add the Domain Service Class to the Domain folder. in the wizard select the DataContext, uncheck the Enable Client & Expose ODate checkbox Check bothe table & their corresponding Enable Editing tables checbox Check the Generate Metadata class Click OK. In Global.asax set Scaffold to true and add the DomainService name. Build and run.   Pages List and Detail are working fine. But if I try to insert a new record, I get the error "FaqId is required" Faq_ID is the primary key in the database table and it is set to Identiy. The Datacontext is correct, it marked the FAQ table with <Global.System.Data.Linq.Mapping.ColumnAttribute(Storage:="_CustomerId", AutoSync:=AutoSync.OnInsert, DbType:="Int NOT NULL IDENTITY", IsPrimaryKey:=true, IsDbGenerated:=true)> _   I tried this using Linq2Sql, Entity Framework, And both in VB and C# with the same result. I am using VS20

Get primary key values from insert page and route to details page in a Dynamic Data Domain Service A


I finally figured out how to retrieve primary key values from the insert page template that are inserted via defaults in a SQL Server database. I wanted to get the keys so that I could route the user from the insert page template to the details page template (regardless of whether it’s a custom route or not). There are a number of scenarios where separate insert and details pages are desirable, and routing from the insert page back to the list page is not desirable as Dynamic Data does out of the box. Since I could not find an answer to this problem anywhere with significant effort, I decided I would document it for others, I hope you find it useful - it turns out that it's quite simple under 10 lines of code. I also applied the same idea to a Dynamic Data Entities application which works exactly the same except for two minor changes, I have documented it below as well.

For starters, as is documented plenty elsewhere but bears repeating here, you must first annotate your Entity Data Model with ScaffoldColumn = false for identity columns and guids that get assigned with newid() in thedatabase. This tells Dynamic Data not to attempt to pass a null value from the page through to

Routing in dynamic data applications


Im using ASP.Net 4. I tried to modified the code according to following video tutorial. http://www.asp.net/aspnet-in-net-35-sp1/videos/how-to-enable-table-specific-routing-in-dynamic-data-applications

But Product page directs only to ListDetails.aspx page.

This is my code :

<%@ Application Language="C#" %>
<%@ Import Namespace="System.ComponentModel.DataAnnotations" %>
<%@ Import Namespace="System.Web.Routing" %>
<%@ Import Namespace="System.Web.DynamicData" %>

<script RunAt="server">
    private static MetaModel s_defaultModel = new MetaModel();
    public static MetaModel DefaultModel {
        get {
            return s_defaultModel;

    public static void RegisterRoutes(RouteCollection routes) {

        DefaultModel.RegisterContext(typeof(NorthwindDataContext), new ContextConfiguration() { ScaffoldAllTables = true });


Dynamic Data, Domain datasource, Poco and lookups


Mr. Edward,

Excuse my question but: it is necessary to involve in our projects something more than just Dynamic Data or should we make use of all other features available in VS2010 (which will make assume taht they had been left out of the Dynamic Data framework) like: wef, poco, azure, wcf, cloud, mvc, silverllight, ajax, odata, agile, workflow, etc.?

Sorry my ignorance, I'm just transcribing names as they come to my mind and of which I don't know anything about

Dynamic Data, Domain Services & POCOs...


I have a simple navigation property between two pocos (parent/child) and I'm using the [Key], [Include], [Association] attributes to notate the relationships. However, when DomainModelProvider attempts to load my model -- I get this error:

[InvalidOperationException: Can't find To column for column 'myColumnName'] Microsoft.Web.DynamicData.ModelProviders.DomainColumnProvider.Initialize() +649

Rather than parade my horribly broken code around -- I was wondering if anyone has a good resource or guides on how to use DomainService/Dynamic Data together using custom POCO models with 1:1/1:M relationships -- rather than EF/L2SQL driven data models. I figure I'd start there before giving up.


How to update Domain Service from Entity Data Model?


Hi guys,

So I'm using Entity data model to reflect my database and I generate Domain service from my Entity data model.

I understand that if I have changes in my database, I can just choose "Update Model from Database", but there is no "Update Domain service from Model" option available.

How should maintain my domain service? I'm not going to delete away it and regenerate it whenever there are some changes, right?

I need to know what if

- I add in new table in my database, how should I update from database-->model-->domain service?

- I add in new fields in my table, how should I update from database-->model-->domain service?


Dynamic Data. Multiple Custom Pages For The Same Table



I've just started out my first project using Dynamic Data and I've been running into a series of problems. Dynamic Data doesn't seem to be swimming in documentation. Anyway, my setup is:

  • Visual Studio 2010
  •  .net 4.0
  • Dynamic Data Domain Service Web Application Project Template (I have the RIA Services for ASP .net installed)
  • using an Entity Data Model
  • using a DomainService class
  • ASP .net Membership

There are a couple of things I am trying to achieve:

  1. I have my scaffolding turned on for all the tables. I am using the RequiresRole attribute in order to restric access to some tables. I have understood how you can create a Custom Page Template for a certain table, no problems there. I would like to be able to use the default PageTemplates for lets say the Administrator role and the Custom Page Templates for another role; the idea would be that the Administrator would be able to edit anything in the DB, but the restricted user would receive a Custom Page with only a few actions available. Long story short: is there a way to access both the standard and custom templates?
  2. Related to question number 1: Can I have multiple Custom Page Templates for the same table? I saw someone asking

    Combining view-only data and Dynamic Data on insert/edit pages


    Hello all, here's a problem I've been trying to figure out an elegant solution for, but so far I'm coming up blank. I have a situation where I'd like to display view-only data and Dynamic Data together on the same page (without creating custom insert.aspx and edit.aspx pages). I've been playing around with using a SQL view, so that it returns me both my view-only fields and my updateable fields as well. I'm having issues with the insert side of things, the edit page works quite well, and I know I'm going to have to create custom delete logic. The major drawback to using a SQL view though is that to get it to behave you have to 'hack' the .edmx file, and I'm not sure I want to do that. So I guess what I'm asking is that has anyone had any success with this, or should I just bite the bullet and create custom pages for the situation of having view-only data and Dynamic Data on the same page? For the record I'm using the Release Candidate version of VS, and my website is an "ASP.NET Dynamic Entities Web Site". Thanks!

Windows Service Applications Tutorials

You can easily create services by creating an application that is installed as a service. For example, suppose you want to monitor performance counter data and react to threshold values. You could write a Windows Service application that listens to the performance counter data, deploy the application, and begin collecting and analyzing data.

Dynamic Data Templates in GridView ASP.NET 3.5

At a high level, Dynamic Data Templates can be seen as a system to very quickly build up a User Interface linked with the relevant data model, immediately enabling you to perform CRUD operations (Create, Read, Update, Delete) on the database using the specified data source. They provide a powerful method for building up these kinds of applications, and I'm going to focus on an overview of what Dynamic Data Templates actually are, and a few ways of customizing them to suit industry needs.

ASP.NET 4.0 Dynamic Data and Many to Many Entity Framework Entities

I did not play much with Dynamic Data controls in VS2008 and just made a cool discovery in VS2010 Beta 2. This may not even be new, but as I'm sitting 30,000+ feet over the Atlantic ocean, I don't have access to VS2008 at the moment to check.



Dear gentlemen and ladies of the Microsoft Dynamic Data Team,

Mr. Steve Naughton says (and I hope so) that there might be chances that you read the posts published in this forum: I really hope so.

If that were the case then I am formally requesting to you in providing a "real answer" to my question:

I want to customize a dynamic data page (the details one) so I can have access to the data it has been already gathered from the end user UI (details.aspx) and use it to pass this same data to the following controls/pages that I am going to display next time to the end user.

For instance:

I have a screen with different types of data in it: texts, numbers, dates, check boxes, radio buttons and dropdownlists that has been filled with data by the end user. I want now to reset all fields exept the dropdownlist of which I'd like to keep the previously chosen values(the very same thing you do between dropdownlist of List.aspx ad Details.aspx). Even with FoxPro I could do that because data and controls were available there. It was as simple as setting carrying on to true.


I have found my

About Dynamic Data in Visual Studio 2010 / .NET 4



Does anybody here have any pointers to screencasts, demos, webcasts for the latest enhancements in Dynamic Data as listed in above link? I'm repeating them here for ready reference :


  • EnableDynamicData method which enables Dynamic Data features in existing ASP.NET applications and DataSource controls
  • A new QueryExtender control, contained in the sample projects to simplify common data filtering operations. It supports a rich ASP.NET declarative query syntax that makes it easy to do things like search data for text or have filters based on ranges
  • A new Dynamic Data filter model that enables the developers to apply templates to pages just like field templates (including user defined filters)
  • New field templates of Email, URL and Enum columns
  • Support for inheritance in Entity Framework and Linq to SQL
  • Support for many to many relationships in Entity Framework
  • New Entity Templates which allow fine control over how an object is displayed and edited
  • DynamicHyperLink control for building links to tables and actions
  • Declarative support for D

AutoGenerateSelectButton="False" ignored when using Domain Service


Crosspost from RIA Services forum: http://forums.silverlight.net/forums/t/196466.aspx

I'm creating a Dynamic Data application in VS2010 and have recently switched to using a Domain Service to give greater control over the data presented to the client. I've noticed that the AutoGenerate<Action>Button attributes on my GridView are being ignored. The presence of the Edit and Delete buttons appear to be contingent on the existence of Update and Delete methods on the partial classes autogenerated in the Domain Service, but i'm not seeing how to control the generation of the Select button. Is there a way to control this from within the Domain Service class?

How to sell Dynamic Data to the bosses


I have a project which has gone from Excel report to a SharePoint Custom List and now they have tried to make it an application growing legs with additional list hinging off it and no real way to clean up data from one when it deleted from another etc..(unless we add handlers etc which we don't want to do).

It was envisiaged as a simple one page list to generate some reports off of but it more a data driven application they want now.

I am looking into a way after stating this to my boss and am intrested in the quickest most flexible way to achieve this and to sell it to him.

I am more a .net person but also know plsql and most of the team I work with are Oracle specialists.

We currently have at are disposile .net, php and oracle products (portal, plsql, forms and oracle application express.)

We are at a transition stage trying to move away from Oracle Forms and I believe that .net is a better fit that php for production and readability of code.

So I am considering placing Dynamic data on the table for this project as it all data driven with data being inputed and manipulated and then reports being generated (either via code or we could hitch in a reporting tool like mssql or discover.)  The main issue will be the data will be in Oracle so if Dynamic data can handle this then it be perfect as
