I have a combo box that updates the filter proprerty of a dataview, which
works fine but when the form tries to close I get a
system.nulreferenceexception.

this is the code in the selectedindex_changed event
dvModels.RowFilter = ("fimakefk = " + Me.cboMake.SelectedValue.ToString)

I have used IsNothing for both the dataview and the contol and both return
false, so I am not sure what is throwing the error.

Probably the simplest would be to set a boolean flag that is true when
the form is closing. So, if not flag, then set the row filter.
