This part of the process works almost exactly like the page you created in the previous tutorial, so much of this tutorial will be familiar. NET operator that represents the current website root.) The result is that this part of the markup in the column simply produces something like the following markup at run time: will be different for each row. The three columns you originally had in the grid displayed only data values (title, genre, and year).
There are several ways you could implement a way to edit an individual movie. You specified this display by passing the name of the database column — for example, Named Parameters and Positional Parameters for a Method Many times when you've called a method and passed parameters to it, you've simply listed the parameter values separated by commas.
Insert, Select, Update and Delete statements these are basics of a programming because these are common coding practice which applies in development of application or a website associated with the database.
Insert, Select, Update and Delete altogether also known as DML (Data Manipulation Language) statements which helps in managing the data with the database within schema objects.
As we'll see in this tutorial, these statements can be created manually or can be automatically generated by the Sql Data Source s Configure Data Source wizard.
Since we ve already discussed the inserting, editing, and deleting capabilities of the Grid View, Details View, and Form View controls, this tutorial will focus on configuring the Sql Data Source control to support these operations.
I use a series of textboxes and dropdownlists which are populated by the datasource but for some reason i cant update them.
In a single database we can create any number of data tables.
As discussed in An Overview of Inserting, Updating, and Deleting, the Grid View control provides built-in updating and deleting capabilities, while the Details View and Form View controls include inserting support along with editing and deleting functionality.
These data modification capabilities can be plugged directly into a data source control without a line of code needing to be written.
This tutorial shows you how to update (change) an existing database entry when you use ASP. It assumes you have completed the series through Entering Data by Using Forms Using ASP. What you'll learn: helper so that it displays an Edit link next to each movie: When you click the Edit link, it takes you to a different page, where the movie information is already in a form: You can change any of the values. The syntax for the new column might look a bit complex, but that's only because it puts together several elements. If you concentrate on just the Some background about how the grid works: the grid displays rows, one for each database record, and it displays columns for each field in the database record.
When you submit the changes, the code in the page updates the database and takes you back to the movie listing. While each grid row is being constructed, the operator in the previous tutorial; it's an ASP.
