Hi, I'm a programming noob and I'm having trouble w/ the DataGridView. The grid on my form has 3 columns (Position | Length | Type). I also have 2 textboxes, 1 for "POSITION", 1 for "LENGTH", a group of radio buttons for the "TYPE",and an "ADD" button on my form. I want to be able to fill in the textboxes, choose the type (radio button), then click the "ADD" button to add the data to the DataGridView in a new row -

Example:

new row = ( Position | Length | Type )

CODE-->

VB

Private Sub btnADD_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnADD.Click
'Add new row
DataGridView.NewRow
'Add data to the corresponding cells
DataGridView.NewCell(0,0) = txtPosition.Text
DataGridView.NewCell(0,0) = txtLength.Text
If radV.checked = True Then
DataGridView.NewCell(0,0) = "V"
ElseIf radH.checked = True Then
DataGridView.NewCell(0,0) = "H"
End If
End Sub

Then I need to be able to save the entire data from the grid to a notepad.txt file w/ the same line/row structure w/o the column headers. If anyone can help, I would greatly appreciate it!
