Add a global parameter to your ado.net entity data model which can be used to validate a session var

  

is there a way to add a global parameter to your ado.net entity data model which can be used to validate a session variable ? in that way you could have a general rule to get for instance only the records belonging to a specific user's profile logged in, is that possible?

In case that it were possible doing that way you will be making the rule valid for all entities in your model at once. right? 


Validate Bulk Excel Data

  

Hello All ,

I have a requirement  like i have bulk of excel data which i have do validate   and if it is okay then i need to insert the data in the DB .

Validations includes like  datatype, length, precision.. etc ... Wil ahve thousands of records.

Earlier  validation was done in the Stored procedure side where the developer moved the data to  the temp table and loop through each row and validate it . But we are acing performace isues and some time time out error as well.

So  i thought of silution like , Convert the execl data to datattable and  validate the data in UI instead of the DB.

Can some one tell me  whether my approcah is right or still  any other approcah is  there ?

Please provide ur valuable suggestions.


Thanks

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.

Surrogate vs Natural Primary Keys - Data Modeling Mistake 2 of 10

  
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.

Editing the Data in a GridView

  
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.

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.

MS SQL Server: Search All Tables, Columns & Rows For Data or Keyword Query

  
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.

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.

MVC architecture in ASP.Net using C# and Microsoft Data Access Application block

  
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.
