Hi everyone,

I have a TableAdapter which is filled with multiple queries.

I want to use a DataGridViewCell value as a parameter in a TableAdapter query

My current code throws an exception because the DataGridViewCell value is returning as dbNull even though it has a value.

Here is the current code which is taken from a Form KeyUp event:

Select Case e.KeyCode
            Case Keys.F8
                Dim columnValue As String = DataGridView1.Currentcell.Value.ToString()

                        Try
                            ' Me.Table1TableAdapter.FillByQuery1(Me.Dataset1.Table1, columnvalue)
                        Catch ex As Exception
                            MessageBox.Show(ex.Message)
                        End Try


        End Select

Thanks for your help!
