Hiding columns in Datagrid

I have this code. Has zero effect on the column "style". Please help.

Dim c As DataGridTextBoxColumn
Dim ts As DataGridTableStyle

Me.dgStyles.DataSource = MyStyleTable
ts = New DataGridTableStyle
ts.MappingName = "tstyle"

c = New DataGridTextBoxColumn
c.MappingName = "Style"
c.Width = 0
c.HeaderText = "Style"
ts.GridColumnStyles.Add(c)
Me.dgStyles.TableStyles.Add(ts)

Me.dgStyles.RowHeadersVisible = True

Me.dgStyles.ReadOnly = True

is this for windows form or for asp.net? Where are you calling this piece of code?

mydasx

typically when i see no net effect when i am setting up a control, it means that either i forgot to call my method that sets up the control, or the control is being setup differently later in the execution. Need more info to help.

are you assigning your styles to the grid?

Put this at the end of your code
Me.DataGrid1.TableStyles.Add(ts)

Yeah. I just don't get it. I have tried everything. I added the field names in manually (not with code) by draggin the element control onto the dataset and adding 8 column names. Could this have anything to do with it?

I got it working by fiddling around with the datatable instead.

ex.
MyStyleTable.PictureColumn.ColumnMapping = MappingType.Hidden

Thanks for your effort.
