Readonly Column in a DataGrid... not working!

[johnb41]

I have a datagrid that has it's first column set to a checkbox column.
I need that column to be "checkable" , while all the others not
editable.

So I created columnstyles

First I add a boolean column to my dataset:

Dim dc As New DataColumn("Boo lCol",
System.Type.Get Type("System.Bo olean"))
dc.DefaultValue = False
dc.ReadOnly = False
ds.Tables("Arch ive").Columns.A dd(dc)

Elsewhere, I create the boolean column style. Here's a snippet:

boolCol = New DataGridBoolCol umn
With boolCol
.MappingName = "BoolCol"
.Width = 20
.AllowNull = False
.ReadOnly = False
End With
ts1.GridColumnS tyles.Add(boolC ol)
boolCol = Nothing
DataGrid1.Table Styles.Add(ts1)

I set ReadOnly=False for both the datacolumn and the column style. But
the datagrid keeps my checkbox column to be non-editable. I didn't
show the code, but I also have column styles for the other columns. I
have them set to ReadOnly = True. But if I change it to ReadOnly =
False, there is not difference. My code just isn't reading the
Readonly property.

Help anyone? Thanks so much!
