This first checks to see if the correct command is being called, and then it converts the Command Argument to the ID of the Car object, which it then retrieves from the database using our new constructor, and then fills in the literal and textboxes as well as enabling the button. Moving to the code-behind, we will first need to make sure we are referencing our custom class: Protected Sub Page_Load(By Val sender As Object, By Val e As Event Args) If (Not Is Post Back) Then Bind Repeater() End If End Sub Protected Sub Bind Repeater() repeater_Cars. This can be added manually, or by clicking on the Repeater in Design view, going to Properties and double-click on the Item Command Event field. Following on from the Updating Custom Object tutorial, we will look into how we can add the Update functionality, allowing us to edit an object and then commit changes to the database. Read() Set Object Data(obj Reader) Loop obj Reader. The Stored Procedure will look something like this: Public Shared Function Update Car(By Val the Car As Car) As Boolean Dim connection As New Sql Connection(Web Configuration Manager. To String()) Try Dim cmd As New Sql Command("sp_Update Car", connection) cmd. By using objects, we could first make the changes and then decide whether or not to save these changes to the database. A data provider is used for connecting to a database, executing commands and retrieving data, storing it in a dataset, reading the retrieved data and updating the database. Net consists of the following four objects: Data Adapter This is integral to the working of ADO.Net since data is transferred to and from a database through a data adapter.However, in this example, we will use the class of the previous tutorial to add a method to update the object. If you have not followed that tutorial yet, it is recommended. Once you have the project opened up, open up the from App_Code.
So its work is basically simply save on record in your data base and if you edit want so you can change it. thanks Note: Due to the size or complexity of this submission, the author has submitted it as a file to shorten your download time.
In the following sample scenario we are going to demonstrate how the implementation can be achieved. NET Data Table that loads its data from a component is bound to Rad Grid View control.
This approach allows us to update the database when the end-user changes the current row in Rad Grid View.
The object model can be pictorially described as: The data residing in a data store or database is retrieved through the data provider.
Net applications for retrieving, accessing and updating data. Net object model is nothing but the structured process flow through various components.
