I am connecting to a web service that returns a dataset that I use as a datasource for a windows client datagridview.
Once a user has made changes to the datagridview record(s), how do I get those changes back to the connected dataset and back to the remote database.
I wrote the sql update function in the service:
Code Snippet from web service
<WebMethod()> _
Public Sub Update_equipment_repair(ByVal repair_id As Int64, ByVal date_entered As DateTime, ByVal date_sent_in As DateTime, ByVal date_returned As DateTime, ByVal damage_description As String, ByVal vendor_id As Int64, ByVal repair_description As String)

This displays the records perfectly and I figured out how to delete and insert records via web service.
writing updates from the datagridview back to the database.
I am writing a small windows client application that accesses data using a web service that returns datasets.When the dataset is returned, a datagridview's datasource is set to the dataset.
My question is, how do I write changes that were made in the datagridview back to the dataset and then back to the remote database.

I'm using Microsoft Visual Studio 2008 to create an application (.VB). The application connects to a Microsoft Access 2007 database. When the user starts the application, the application pulls in the data from the database via the "TableAdapter.Fill" method. The user can then add/update/delete records in the form and those changes are saved and confirmed in the database. The problem is when the user close completely out of the application and restarts it, the modifications that were made and originally sent/saved to the database are wiped/deleted. It appears that the dataset in the application never saves the modifications and when the program restarts it uses the data that was originally loaded into it during the design/build phase of the application.

I have a datatable populated from an SQL Server 2008 database table. I created a DataAdapter with a commandbuilder to manage the updating, inserting, and deleting of records. The Updating and Inserting work as expected. However, Delete does not. The code runs through just fine without any errors. The number of records in the datatable after the row is deleted even reflects the deletion. The DataAdapter.Update works fine without any exceptions. But when checking the actual table in the SQL DB the deleted record is still there.Here are the parts of my code that deal with this table.

I have a GridView that is tied to an EntityDataSource. Most columns are normal bound columns, but two are itemtemplates. When I attempt a delete on one of the rows I receive the following message:
"A property named 'Building1.building_name' was not found on the entity during an insert, update, or delete operation. Check to ensure that properties specified as binding expressions are available to the data source."
I'm not sure how it is possible that this isn't available, since it displays the element just fine when I'm just viewing - it just throws the error when I attempt deleting a row?
I have created a test application to display data in a datagrid, using the Dataset Wizard per the help. All fine - data is displayed.
I then added insert, delete and update queries by selecting Edit Dataset with Designer, selecting the table and adding a query for each action via the TableAdapter Configuration Wizard. In Advanced Options, all boxes are checked, and on the last screen of the wizard it says it has generated SELECT, INSERT, UPDATE, DELETE statements, table mappings, Fill, Get and update methods. The TableAdapter shows four entries: Fill, GetData(); DeleteQuery; InsertQuery; UpdateQuery. On the DataGridView Tasks page, Adding, Editing and Deleting are checked and the data preview shows data.
When I run the application, I can update, add and delete data, but this is not saved.
I followed an example from a VB 2008 Wrox book on creating, binding and updating a data set but I am having a problem. The code is supposed to automatically generate the update/insert/delete statements for me (according to the book) but when I call the update command, the data is not saved.

I am using this code to Add rows to a SQL database, and it adds the row to the SQL database if column 7 is not null.
