Updating a datatable
The url should be displayed in the editable format.
A date axis displays dates in chronological order at set intervals or base units, such as the number of days, months, or years, even if the dates on the Excel sheet are not in sequential order or in the same base units.
The way the architecture works with the Data Adapter is that you can make any changes you want to the filled Data Set, and it won't affect the database until you call the Update method.
When Update is called, the Data Adapter will attempt to execute each query (UPDATE, INSERT, DELETE) on every row of the Data Set that has been updated, inserted, and deleted.
Note: The Tables member of Data Set represents all Data Table objects attached to a Data Set. Adding a Data Row to a Data Table Dim row1 As Data Row = ds. To test this source code create a Windows application, drop a Data Grid, and three buttons- Insert Command, Update Command, and Delete Command to the form.
Listing 5-46 Creates a new Data Row, sets the data of Data Row members, and adds rows to the table using the Add method of Data Table. Listing 5-48 show the code on the Insert Command button-click event.
