DataGridView Update

Question

I\'m using 2005 Windows Forms in C#. I\'ve only been working at this for a day, so go easy please.

I\'d like to have a submit button that saves changes to a DataGridVie

Answer 1

Update on a table-adapter needs a DataSet.

You need to instantiate a scDB DataSet with the table, update that table and call to Update for the table-adapter.

Answer 2

If you've configured the proper TableAdapter to go with the DataTable specified (Right-Click on the TableAdapter section and select "Configure...'), you'll have a wide variety of options.

After doing this on my own DataTables I'm able to update by

• Strongly Typed DataTable
• DataSet
• DataRow DataRow() - Array of DataRows if multiple require updating
• Individual Columns (provided you have unique key to tie the row to)

Answer 3

Sam,

the update needs a table so you could try something like:

TableType table = (TableType) stagingGrid.DataSource;
myStagingTableAdapter.Update(table);

where you'll have to substitute TableType with something appropriate.

But a better approach would be to use drag-and-drop and learn form the code.

1. Select Data|View Datasources. Your dataset should be visible in the DataSources Window.
2. Drag a table to a (new) form. VS2005 will add a load of components and a few lines of code.

The form will now have a instance of the dataset and that is your reference point for Adapter.Fill and .Update methods.
