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.

In case you're new to the series I've compiled a list of ten data modeling mistakes that I see over and over that I'm tackling one by one. I'll be speaking about these topics at the upcoming IASA conference in October, so I'm hoping to generate some discussion to at least confirm I have well founded arguments.

The last post in this series Referential Integrity was probably less controversial than this one. After all, who can argue against enforcing referential integrity? But as obvious as surrogate keys may be to some, there is a good deal of diversity of opinion as evidenced by the fact that people continue to not use them.

In addition to deleting a GridView's underlying data, another common need is to allow end users to edit the data displayed in a GridView. With ASP.NET 1.x's DataGrid control, editing the data is certainly possible, but requires creating three event handlers and writing a dozen or so lines of code. With the GridView and ASP.NET 2.0, it is possible to create an editable GridView without writing a single line of code! All of the necessary functionality is encapsulated within the GridView.

The GridView allows editing on a row-by-row basis. An editable GridView contains an additional column with an Edit button in each row. When the end user clicks on an Edit button that row becomes editable, causing the Edit button to change to Update and Cancel buttons and the other columns to become TextBoxes. The end user can then update one or more column values and click Update to save their changes.

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!

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.

If you need to search your entire database for specific data, this query will come in handy.

So when a client needs a custom report or some sort of custom development using Great Plains, most of the time I will have to track down the data in the system by running this query and find the table(s) it is in.

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.

The Model-View-Controller (MVC) pattern separates the modeling of the domain, the presentation, and the actions based on user input into three separate classes [Burbeck92]:

Model. The model manages the behavior and data of the application domain, responds to requests for information about its state (usually from the view), and responds to instructions to change state (usually from the controller).

View. The view manages the display of information.

Controller. The controller interprets the mouse and keyboard inputs from the user, informing the model and/or the view to change as appropriate.

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.

I have AD domain which has 100000 users, I want to display all the users in gridview controls.Actually it is displaying users in gridview after parsing entire domain which takes around 30 min. I want to display the users while loading itself.It is continously getting user information from AD domain and getting each user details, I want to display the users information which already queried instead of waiting till getting all users information

i want to display data in gridview binded to a sql datasource
but the problem part is i want to bind a field of that datasource to a dropdownlist and when a item is selected in that dropdownlist then correcposnding to that data will be displayed in gridview...

I have to display data from excel sheet into my gridview and also I need to figure out a way to store data into excel files from my web page. I am using C# 3.5, VS 2008.

I previously made a master slave datagrid using Visual Studio 2003 .Net (original article) that would allow users to show data to clients using collapse and expand features. These features however did not carry over to gridview for many users. This tutorial will explaing how to create a collapsable/expandable gridview in frameworks 2.0 and higher

Last week, I introduced ASP.NET 2.0's GridView data control and covered the basics of using it. This week, I go a step further by going into the details of working with the data contained in the control. This includes viewing, editing, and deleting data. Thankfully, the GridView control makes it easy to utilize these features. Before diving into these topics, I begin with an examination of the different field types supported by the GridView control.

Typically when you display a datagrid you will want to show data from a related table. There are 3 different ways to accomplish this with NetTiers. You can use a custom stored procedure, deepload functionality from the code behind, or a strongly typed datasource control. We'll provide an example of each

The Interoperability services make it veryeasy to work with COM Capable Applications such as Word and Excel. Thisarticle reveals using Excel from a managed application. Excel is thespreadsheet component of Microsoft Office 2000. The majority of Excelprogrammatic functionality is exposed through Automation via the typelibrary Excel9.olb. The intention of this article is to express that amanaged application can interrelate with Excel as a COM server.
