Hi,

I have the following code which I am using to bind an object to the  
Window Forms dataGridView control:

def bind\_customes\_to\_grid(customer)

$gvCustomers.DataSource = customer

end

Now, I need to convert the customer into a collection so it can be  
binding to the DataGridview control. How can I do that?

Here is one possible solution:

def bind\_customes\_to\_grid(customer)

list = Array.new  
list[0] = customer

$gvCustomers.DataSource = list

end

Here is another version:

def bind\_customes\_to\_grid(customer)

$gvCustomers.DataSource = Array.new.push(customer)

end
