Binding a dataset to textbox controls to update the dataset.

Asked by gazzacrowe in .NET, Microsoft Visual Basic.Net

Tags: Microsoft, VS2005, 2005, VB.NET 2005

Hi,
I am currently looking for away to manage updating data using a dataset and textboxes on a windows form.
Scenario:
1. I'm retrieving data from a database and populating a dataset with the results (about 10 rows of data in 1 table).
2. I am then binding the dataset to a datsgridView on the form. (All is good)
3. I have a few textboxes on the form and i bind a row to the text boxes. (ill include the code below)
4. As i click on the datagridview row the contents of that row will be displyed i the textboxes. (All is good). Everyclick of the row displays new data (i am using a BindingManagerBase here to iterate through the bindings)

What i would like to happen next:
Edit one of the textboxes and when the user leaves the textbox that the changes will get saved in the dataset and reflected in the datviewGrid.
The dataset is then passed to a function to update or create a new record (Note this is NOT being done through an SQLDataAdapter)

My take on this is that i've bound the textboxes to the grid, so would this be a one way binding ds -> textbox. Do i need a binding from textbox -> ds or is this handled in the binding.

I've been mssing with bindingsources as well.

Any help would be greatly apprciated.

Cheers
Steven
