I'm using the gid control and I am trying to add a column through code, but this example below will not add the column
even if I just do grid.columns.add() it will not add the column.
For i As Integer = 0 To dt.Columns.Count - 1
Dim Col As EO.Web.GridColumn
Col.DataType = EO.Web.GridColumnDataType.Auto
str = dt.Columns(i).ColumnName
Col.DataField = str
Col.HeaderText = str
Col.AllowSort = True
Grid.Columns.Add(Col)
Next
Error I get is Col is null and MustInherit Public Class
How can I add a column to an existing grid control through code?

Hi Scott,
You will have to use New to create a GridColumn first. Without doing that, Col is Nothing. So of course you will get a "Col is Null" error. Also you need to decide which type of column you want to create (StaticColumn, DateTimeColumn, etc), you can not create the abstract GridColumn.
Thanks
