Stupid beginner question :o)

Question

Hi there I'm just starting to work with C# and the ADO.NET. As a test project i've choosen a simple Customer-Management Application. So here's my problem: In my main form I have a DataGrid that should display all my Customers. I have a MainMenu and there I select Add new Customer wich opens a form to enter the Data and saves it in a DataSet (and in an XML-File). How do I update the DataGrid in the Main Window when a Customers has been enterd in my frmAddCustomer form? I now create the Dataset for storing the Customer-Data in the btnSave_Click Method. Do I have to use the DataSet from the MainWindow...and if so HOW? :o) Please help a newbie. :o) Kind regards Iceman

Use dataset as parameter of constructor of AddCustomer form -or- create DataSet property in AddCustomer form and set it in main form after creating AddCustomer form.

OK but my problem is how do I access the DataSet used in the MainForm in my AddCustomer Form?

If You add record to Dataset binded to DataGrid (at WinForm) it should be displayed. At WebForms You must use DataBind I think. To update database create DataAdapter object and use DataAdapter.Update method.
