Problem with displaying and processing dynamic data

Posted By:      Posted Date: September 21, 2010    Points: 0   Category :ASP.Net

I need to dynamically generate a list of images in table format.  The images can be found in either art or picts, in temp, or in temp and in one of the other two (duplicate image). 

The idea is to display any duplicates prior to copying anything over from temp to either art or picts, so I'm thinking of adding radio buttons if the same image is found in two folders.  I also want to add a submit button.  The user selects the image they want and clicks the button.  If they want the new file it's copied over then deleted.  If they want to keep the existing file the new one is just deleted.  If they select nothing, both versions of the file are deleted.  So the table will look something like this:

temp         art            picts         process
z-123                                           delete button
() z-234                       () z-234

Problem in displaying values for foreign keys in Dynamic data asp.net web app


I have the following tables in my database which are as given under:


Table 2: CREATE TABLE [dbo].[PromotionCodes]( [PromotionCode] nchar NOT NULL, [CustomerPromotionDiscountID] [int] NOT NULL, [EmployeePromotionDiscountID] [int] NOT NULL, [IsActive] [bit] NOT NULL, CONSTRAINT [PK_PromotionCodes_1] PRIMARY KEY CLUSTERED ( [PromotionCode] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY]

There is a foreign key relationship between columns (1) PromotionID of table PromotionDiscountValues and CustomerPromotionDiscountID of table PromotionCodes and (2) PromotionID of table PromotionDiscountValues and EmployeePromotionDiscountID of table PromotionCodes

When i browse the PromotionCodes table in the dynamic data listing, the following columns get displayed:

  1. PromotionCode

  2. IsActive

  3. Prom

I am trying to display the menu items and submenus in a navigation menu control.

I am trying the code from this page; http://www.aspnettutorials.com/tutorials/controls/sqldb-driven-menu-csharp.aspx

ASP.NET Dynamic Data Deployment Problem


Hi, everyone..

I have a problem to do ASP.NET Dynamic Data Deployment.

I can deploy my website successfully to a Web Server. Everything runs well, except the dynamic data pages.

When I click on any table pages, it will be rerouted to {table}/List.aspx.

But I got this error on every table.

Server Error in '/MySite' Application.

The resource cannot be found.

Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable.  Please review the following URL and make sure that it is spelled correctly.

Requested URL: /MySite/Doctors/List.aspx

Version Information: Microsoft .NET Framework Version:2.0.50727.4952; ASP.NET Version:2.0.50727.4955 

Can you tell me what is the problem? Thanks.

Dynamic Data Deployment problem



My Dynamic Data website works locally in debug mode. When I deploy it to discountasp.net, I can view lists of items, but when I click 'Update' it just refreshes the page without making changes to the DB. Clicking on any paging functionality also just refreshes the current page.

I read on ScottGu's blog that I should add this in the config, however the "dynamicData" element gives me an error and can't be added.

<system.web.extensions><dynamicData dataContextType="" enableTemplates="true">

My config file does include: 

<sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, System.Web.Extensions, Version=, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

I'm running Windows 7, VS2008, and .NET 3.5 and 4.0 is installed locally.

Thanks - any ideas are appreciated!




Dynamic data and Entity framework problem when using a function in RegisterContext


I am trying to use asp.net dynamic data using entity framewrok. my entity framework (edmx file) is in another dll and I dont want to put connection string in config files.
I use this code to register my objectContext in global.asax:

model.RegisterContext(() => new MyObjectContext("EntityConnectionString"), new ContextConfiguration() { ScaffoldAllTables = true });

the first page (the list of tables) is ok, but when i click any table, i get this error:

The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid.

 it seems that for the second request, it checks the web.config to look for entity connection string.


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.

Displaying Data using ASP.NET 2.0 Repeater and C#

This tutorial will show you how to display data using the .NET Repeater Control, ASP.NET 2.0 and C#.NET

The Repeater control is a powerful tool and is easy to use.

First, you will need to import the System.Data.SqlClient namespace.

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

Problem with Dynamic Button


Hi friends,

I am trying to make a page inspired from http://login.qlikview.com/help.aspx

here I have made a dropdownlist and on clicking I am able to dynamically add the textboxes and radio buttons using placeholders. My problem is I am not able to use a dynamic number of submit buttons. In the page (link above) I need to make the submit button available for two choices and invisible for one.  But the option dynamicbutton is not available alike dynamicTextboxes etc. What could I do? Is there any other way I could figure out to implement this.

Thanking you in advance,


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
