I am getting this error trying to dynamically added a column to my DataGrid.

I have the following code:

Function CreateBoundColumn(c as DataColumn) as DataGridColumn
  Dim column as DataGridColumn  = new BoundColumn()
 column.DataField = c.ColumnName                                    <----  
the error
 column.HeaderText = c.ColumnName.Replace("_"," ")
 column.DataFormatString =setFormating(c)
 return column
End Function

But the code I borrrowed this from was:

'add bound columns to the datagrid
Dim datagridcol As New BoundColumn
datagridcol.HeaderText = "Candy Type"
datagridcol.DataField = "CandyType"
DataGrid1.Columns.Add(datagridcol)

Here they use DataField the same as I do.

Am I missing something to make this work?

Thanks,

Tom
