Here's my Code (practice)

 Dim row As Integer = dgvCart.Rows.Count
        Dim tb As TextBox() = New TextBox() {txtShipAddress, txtBookName}
        dgvCart.Rows.Add()

        For i As Integer = 0 To tb.Length - 1
            dgvCart(i, row).Value = tb(0)

Next


The error is
"No row can be added to a DataGridView control that does not have columns. Columns must be added first."

Alright that's pretty straight forward. Declare some column objects there are a few, and add them to the datagridview control. Add some rows after, and then add some objects to those rows. One issue I see right there is that you're trying to place a control into a property. So I ask you what is the data type of the .Value property of the dgv row?
