ObjectDisposedException on second use

[LLcoolQ]

I have created a DataGridViewNumericUpDownColumn using this from MSDN:

http://msdn.microsoft.com/en-us/library/aa730881(vs.80).aspx

I build my grids at run-time, here is the code for adding the column:

Dim colQtyShipped As New DataGridViewNumericUpDownColumn
With colQtyShipped
.Increment = 1
.Minimum = 0
.Maximum = 250
.DataPropertyName = "QuantityShipped"
.AutoSizeMode = DataGridViewAutoSizeColumnMode.None
.HeaderText = "Packed"
.Name = "QuantityShipped"
.[ReadOnly] = False
.Visible = True
.MinimumWidth = 50
.Width = 50
End With
itemGrid.Columns.Add(colQtyShipped)

The first time i open a form, all works well. The column displays,
the arrows work fine, the data binding works fine.

As soon as i close the form and open a new instance, I get this error:

Cannot access a disposed object
Object name: 'NumericUpDown'.

System.ObjectDisposedException was unhandled by user code
Message="Cannot access a disposed object.\r\nObject name:
'NumericUpDown'."
Source="System.Windows.Forms"
ObjectName="NumericUpDown"

It points to this line of code

paintingNumericUpDown.TextAlign =
DataGridViewNumericUpDownCell.TranslateAlignment(cellStyle.Alignment);

in class DataGridViewNumericUpDownCell


Really not sure what is causing this. i am not trying to reuse an
object, trying to create a new one.

If i leave the first form that used this open, i can open and close
forms forever. as soon as i close the form that it was first used on,
the ObjectDisposedException is thrown. I can work around this for now
by creating an invisible instance of this at app startup, but will dig
in and figure out how to get around this
