It is a part of the base class library that is included with the Microsoft . It is commonly used by programmers to access and modify data stored in relational database systems, though it can also access data in non-relational sources. NET is sometimes considered an evolution of Active X Data Objects (ADO) technology, but was changed so extensively that it can be considered an entirely new product. NET is conceptually divided into consumers and data providers.The consumers are the applications that need access to the data, and the providers are the software components that implement the interface and thereby provide the data to the consumer.Free counters Added on January 19,2012 Follow Me @vmsdurano A bit About Me Disclaimer The opinions expressed herein are my own personal opinions and does not represent the opinions of my employers. Contol)Text; it werk just Fine any comment and thx for the code Instead of adding a Customer ID to your table and later pulling the text to get the ID number, a more reliable way to do it is to add a Data Key Names field to the grid example in the page: You can then access this information at any time with the following in code: Grid View1. Row Index]["id"]); You can do this with any field, but I've found customers get confused when they see the ID field and kept asking me why it was there, this also eliminates any issues if you change the display order of your table later (maybe add an edit/update/cancel control) Hey...great article ;)But I got a problem... So here I go with my example:protected void Grid View1_Row Updating(object sender, Grid View Update Event Args e) and the debugger says: Exception Details: System. Nor does it represent the opinion of my dog, because I don’t have one. I have a project that I coppied the above code into. Data Keys[Row Index]["Customer ID"]in the Update event it would be something like:int Customer ID = Convert. Format Exception: Input string was not in a correct format. Here we will learn how to create a MVC 4 CRUD operation using ADO. We have already learnt how to create CRUD operations Using ADO.NET Entity Framework but if you have an application frequently doing database transaction then using ADO. Before start creating application let's have a look on database part first.Functionality exists in Visual Studio IDE to create specialized subclasses of the Data Set classes for a particular database schema, allowing convenient access to each field through strongly typed properties. NET that supports the development of data-oriented software applications.
Here is Customer table view inside that select Web and then project type select ASP.The last parameter is a boolean value which tells the method whether to execute an Insert (false) or Update (true). In-order to perform Edit and Update in Grid View we need to use three events ( Grid View_Row Editing, Grid View_Row Canceling Edit , Grid View_Row Updating). For those who do not know on how to generate Events in Grid View you can follow these steps below: I have a project that I coppied the above code into. I don't have errors on screen but in database my object wasn't updated.I think that's not working because my Supplier have foreign key from Adress table. Begin Form()) My controller method: Hi Nadezda Janjetovic, I suggest you set a break point and debug your code step by step, please make sure it not throw an exception in the edit action.
