Changing datagrid values

Hi All, Ive got this function that changes the width of the columns on a datagrid however i would like to change the value of col 2 (the datagrid only has two columns)

The values of what i wana change are

Null = None
1 = Type A
2 = Type B

Can any one help ? The function is below....

VB Code:

Private Sub AddCustomDataTableStyles(ByVal dstData As DataSet, ByVal dgName As DataGrid)
 
        'Clear the table styles for the datagrid
        dgName.TableStyles.Clear()
 
        'Declare local variables
        Dim tsTableStyle As New DataGridTableStyle
        Dim tcTextCol As DataGridTextBoxColumn
        Dim intCounter As Integer
 
        'Map the table style to the table in the dataset
        tsTableStyle.MappingName = dstData.Tables(0).TableName()
 
        'Add textbox column style for each column in the dataset 
        For intCounter = 0 To dstData.Tables(0).Columns.Count() - 1
 
            'Reinstantiate the text box column and set mappings and attributes
            tcTextCol = New DataGridTextBoxColumn
            tcTextCol.MappingName = dstData.Tables(0).Columns.Item(intCounter).ColumnName
            tcTextCol.HeaderText = dstData.Tables(0).Columns.Item(intCounter).ColumnName
 
            Select Case tcTextCol.MappingName()
                Case "Address"
                    tcTextCol.Width() = 173
                Case "CaseType"
                    tcTextCol.Width() = 75
                Case Else
                    tcTextCol.Width() = 50
            End Select
            'Add the column to the table style
            tsTableStyle.GridColumnStyles.Add(tcTextCol)
        Next
        'Add the table styles to the datagrid
        dgName.TableStyles.Add(tsTableStyle)
    End Sub
