Empty a Datagrid

[Imad Belabbes]

I just started working with C#.
I have a combobox where upon selecting a product a grid is displayed in the
form with a bunch of data. When selecting another product, I get an
exception because the datagrid is not empty.

How do I empty a Datagrid.

Thanks, Imad.

Imad, what you need to do is use databinding in the form, and let the
data binding automatically show each product's data from the combo.
This is what's called a "Master-detail" view, in which the "master" is
a product in the combo, and a "detail" for each product is displayed
in the datagrid.
THere are a lot of ways to do this, but here's an article that will
get you started:

(Lesson 4 explains how to make a combo box act as a "master")

good luck.
