Binding WPF Controls to an Entity Data Model

In this interview, programming writer, McLean Schofield, demonstrates how to bind WPF controls to an entity data model, using Visual Studio 2010 Beta 1. You can also learn more in the topic: Walkthrough: Binding WPF Controls to an Entity Data Model.

Using ASP.NET 3.5's ListView and DataPager Controls: Displaying Data with the ListView

Prior to ASP.NET 3.5, developers who needed to display a set of records could choose between the GridView, DataList, and Repeater controls. The GridView provides rich data features, but has a very boxy layout; the DataList and Repeater allow for a more flexible layout, but lack the "point and click" data features found in the GridView, DetailsView, and FormView controls. The ListView bridges the gap between layout flexibility and built-in data features.

This article, the first in a series of articles on the ListView and DataPager controls, looks at the ListView's many available templates and illustrates how to display data. Read on to learn more!

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.

Need help regarding C# / AJAX Dynamic Controls creation


radiobuttons is assigned before page init.. 

public partial class Default : System.Web.UI.Page
//Assign values as a specific Dynamic WebControl Creation.
List<RadioButton> radioButtons = new List<RadioButton>();
List<CheckBox> checkBoxes = new List<CheckBox>();

Then I created a class that would dynamically create a table containing the available flights depending on session.. (See CallPageLoad())

The placeholder and button is inside the UpdatePanel...

on the button inside the update panel, (btnSelect)

i have this code which works... 

protected void btnSelect_Click(object sender, EventArgs e)

Label1.Text = Convert.ToString(radioButtons.Count);

It detects the number of radiobuttons that were dynamically created...

But when I use the following code inside the BtnSelectClick event...

//PLS HELP.......
foreach (RadioButton button in radioButtons)
if (button.Checked == true)
Label1.Text = "You select... " + button;



It does not work even though t

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 });


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

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

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
