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 DataGridView. I’ve gotten data into the DGV and can edit, but am stuck on the Update().

I’ve created an .xsd named scDB and one DataTable called – SSIS Configurations Staging. I then added a new query that takes a parameter.

Here is my code so far:

//Declared at top of form class     scDBTableAdapters.SSIS_Configurations_StagingTableAdapter myStagingTableAdapter = new scDBTableAdapters.SSIS_Configurations_StagingTableAdapter();   //After a form event             stagingGrid.DataSource = myStagingTableAdapter.GetDataBy(filterName.Text.ToString());  //On Submit click:  myStagingTableAdapter.Update(?What Goes Here?); 

What gets passed to the Update method? I know it needs a dataTable, but I don’t know how to reference what is in the GridView. In most code examples people define the DataTable – but I do not. I assume this is being done behind the scenes when I created the TableAdapter. Thanks for the help.

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.
