As you can see from listing 5-48, I created a filled Data Set and created a new Data Row using the Data Table. After creating a Data Row, I set its column values and called the Data Adapter's Update method and displayed data in the Data Grid.I added new rows to the Customers table with Customer Id, Customer Name, and Company Name (named Tst ID, Lana Jackob, and Mindcracker Inc., respectively). Adding data using a Data Adapter's Update method Listing 5-49 shows an example that edits row data.
In Data Grid, every Cell is in the form of Text Block Framework Element type when it is not editable.
Listing 5-50 deletes the row with the value Tst ID.
As you can see from the code, I called the Find method to find the row and called the Delete method of the Data Row.
As you saw in the Data Table, Data Row, and Data Column sections at the beginning of this article, you can use the Delete method of a Data Row to delete a row.
The Add New method of the Data Table adds a row to a Data Table.
To insert, update, and delete data using a Data Adapter, you create an Ole Db Command object with INSERT, UPDATE, and DELETE statements and set the Insert Command, Update Command, and Delete Command properties of the data adapter to Ole Db Command.
You can avoid building Command objects manually by using Command Builder.
Introduction A Data Grid View control can be used to display data from a database.
A table can be displayed from a database in a Data Grid View, using the Data Adapter class and data logic.
Now run the application, click on the update button in the row and select cell to be changed (in this example ‘Salary’ and ‘Dept No’ cells can be changed).
After changing cell or cells for the row, use ‘TAB’ on your keyboard to change the focus from the current row to next row.
I was recently working on a requirement to perform Update and Delete operations on a WPF Data Grid control (similar to what developers do in a ASP. The WPF Data Grid is an excellent control to bind with collections and provides various events to work with. This code changes the columns for ‘Salary’ and ‘Dept No’ in edit mode.
