Because a majority of Web applications involve reading data and not updating it, one-way data binding keeps the size and complexity of the page architecture to a minimum for the most common scenarios.
However, there are times when you do want to update data. If you are using a dataset, you can write changes to the dataset and then call the data adapter to send changes from the dataset to the database.
When you are done, your page will look something like the following: The walkthrough will illustrate a number of concepts: To access the data, you will need a connection to the database you want to read from.
