Data GridView Value List

I have a table with 3 columns. It contains numbers of rows. The value of last column is taken from second column which contains a Pair of possible values. I want to populate the third column with a combobox containing the value pair from second column. This value pair will be different for different column. I managed to write a query but it populates the same value list for all the rows.

table structure

PS_CODE        PS_PARAM    PS_VALUE
  A               Y;N          Y
  B               0;1          1

When this value populating on grid some time I want to change the value of Y to N or 1 to 0, then this PS_PARAM value should be shown on a combobox to select.

this is my code

For Each drow As DataRow In dSetChangeStatus.SM_POS_SETUP.Rows

Dim strValueList As String = "Select PS_PARAM FROM SM_POS_SETUP Where PS_CODE = '" & drow("PS_CODE") & "'"

Dim psValues As System.Data.SqlClient.SqlDataAdapter = New System.Data.SqlClient.SqlDataAdapter(strValueList, ConPOS)

Dim ds As DataSet = New System.Data.DataSet()

psValues.Fill(ds, "PS_PARAM")

Dim arrVal() As String = Split(drow("PS_PARAM"), ";")

Dim Column As Janus.Windows.GridEX.GridEXColumn = gridEXSetUp.RootTable.Columns("PS_VALUE")

Column.HasValueList = True

Dim valueList As Janus.Windows.GridEX.GridEXValueListItemCollection = Column.ValueList

valueList.PopulateValueList(ds.Tables("PS_PARAM").DefaultView, "PS_PARAM")

Column.EditType = Janus.Windows.GridEX.EditType.Combo

If PS_PARAM has always 3 signs and the second one is always ";", try to ask your database in this way:

SQL

SELECT SUBSTRING([PS_PARAM],1,1) AS PS_VALUES
  FROM [ERK].[dbo].[SM_POS_SETUP]
WHERE PS_CODE = 'A'
UNION ALL
SELECT SUBSTRING([PS_PARAM],3,1) AS PS_VALUES
  FROM [ERK].[dbo].[SM_POS_SETUP]
WHERE PS_CODE = 'A'

which SUBSTRING() function returns part of string.
You should see results (2 rows):
Y
N

I have never used control: Janus.Windows.GridEX, so i can't help you more.
I think, you should load this data to datatable (not dataset) and populate it with column, but first you should change this part of code:

VB

Column.EditType = Janus.Windows.GridEX.EditType.Combo
valueList.PopulateValueList(ds.Tables("PS_PARAM").DefaultView, "PS_PARAM")
