Updating dataset without dataadapter eudora fast search updating
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.
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.
After that I called the Data Adapter's Update method to save the changes to the database table.
The process was straightforward: We created a disconnected Recordset; we made changes to the data; we called the Update Batch method; and enchantment happened.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.Note: The Tables member of Data Set represents all Data Table objects attached to a Data Set.
