Bind variables are placeholders inside a SQL statement.

How to handle them may vary, depending on what you're doing and what you're looking to accomplish, but WPF comes with two very easy solutions that you can use: The Observable Collection and the INotify Property Changed interface.If the statement does exist in memory, Oracle Database can reuse it and skip the task of parsing and optimizing the statement.Using bind variables makes the statement reusable with different input values.Web Grid™ provides you with various events to handle how your data source inserts, updates, and deletes data records. To update data bound to Web Grid using a dataset, you must retrieve data, check for changes, update changes to the dataset, and update your database using your dataset. What I am hoping for out of this is post is a way that the rows whom check value has changed to be marked as changed/edited so that the data source will update the database with the values of the check boxes.

If all rows are updated this is acceptable as well.

only the initial names from when it was first bound appear, how to fix this?

The Items Source of the list is assigned to a quick list of a couple of users that we create in the window constructor.

The problem is that none of the buttons seems to work. The first step is to get the UI to respond to changes in the list source (Items Source), like when we add or delete a user.

Using bind variables also improves query performance in the database, eliminates the need for special handling of literal quotation marks in the input, and protects against SQL injection attacks.
