Hi

This is driving me mad I keed getting this error:-
"An unhandled exception of type 'System.StackOverflowException' occurred in system.windows.forms.dll"

It seems to be the "dgMaterials(theRow, 7) = thetotal" line within the add row total section that is causing the problem, dgMaterials is my datagrid.

'-------------Add to datagrid---------------------
.Add(New DataGridTextBoxColumn(tblCrrncMngr.GetItemProperties.Item("estitemGross")))

With .Item(7)
.MappingName = "estitemGross"
.HeaderText = "Gross Total"
.Width = 65
.NullText = String.Empty
End With


'-----------Add Row Total------------------------
Private Sub RowTotal(ByVal theRow)
Dim theQty, cellNumber As Integer
Dim theRawcost, theVAT, theRawCostTotal, thetotal As Double

Try
theQty = dgMaterials(theRow, 4)
theRawcost = dgMaterials(theRow, 5)
theVAT = dgMaterials(theRow, 6)
thetotal = (theQty * theRawcost) * theVAT

dgMaterials(theRow, 7) = thetotal

Catch ex As Exception
MsgBox(ex.ToString)
End Try

End Sub
