[RESOLVED] DataGridViewComboBoxCell value is invalid

I have a DataGridView which contains a column of type DataGridViewComboBoxColumn. As I populate this column, everything is fine until the row added contains a different ComboBox item than the previous line. From this point on every additional row added gets the error:

DataGridViewComboBoxCell value is invalid


Here is the code:

Code:

---

Dim DataTypeColumn As New DataGridViewComboBoxColumn

' Setup ComboItems for Data Type
DataTypeColumn.Items.Clear()
DataTypeColumn.Items.Add("Bit")
DataTypeColumn.Items.Add("TinyInt")
DataTypeColumn.Items.Add("SmallInt")
DataTypeColumn.Items.Add("Int")
DataTypeColumn.Items.Add("VarChar")
DataTypeColumn.Items.Add("Decimal")

For iIndex = 0 To myTable.Rows.Count - 1

With dgvPartSetup

.Rows(iIndex).Cells(4).Style.BackColor = Color.FromArgb(224, 224, 224)
.Rows(iIndex).Cells(4).ReadOnly = True
.Rows(iIndex).Cells(4).Value = sDataType

End With
Next iIndex

---

Like I mentioned for the first 7 or so values sDataType = "Decimal" and everything works just fine. The next row, it happens to be "VarChar" and then for all the remaining rows including any subsequent "Decimal" values I get the above error. Any Ideas?

The problem ended up being that the incoming data had some upper/lower case character differences. In the debugger, when I asked if they were equal it told me True. They contained the same characters, but not always the exact same case...
