Dataadapter update not updating database Pantyhose request webcam chat videos
For example, if you call Delete on a row on the Data Set, then when Update is called on the Data Adapter, the Delete Command of the Data Adapter will be called using the particular row in the Data Set.
Note: Keep in mind that this Update is different than a SQL UPDATE statement.
To change an existing row's data, you can directly assign a row's value.
To save data to the data source, you need to call the Data Adapter's Update method.
Thanks for any help you can offer, Ron "Peter Bromberg [C# MVP]" RSH, I haven't looked carefully at your code sample, but I'd be willing to bet that the reason you aren't getting any updates is because the Row States of the rows in the second Data Adapter's table don't reflect any changes.
If you call the Get Changes method on the second Data Set, I bet you'll find you get an empty Data Table in it.
Fill(ds Production,"Companies"); String str Development SQL = "SELECT * FROM [Global].[dbo].[Companies] WHERE Company ID ='" str SQLDest Database "'"; Sql Data Adapter da Development = new Sql Data Adapter(str Development SQL, cn Development SQL); Data Set ds Development = new Data Set(); da Development. If you call the Get Changes method on the second Data Set, I bet you'll find you get an empty Data Table in it.
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. I'll display the result of the Customers table in a Data Grid after adding, updating, and deleting data from the table.
I wrote the code below, which doesn't error..it doesn't work..data is updated.
