How to delete autogenerated columns from Telerik RadGrid?

Question

I dynamically change columns for a RadGrid, for some data sources I need AutoGenerateColumns for other I don't. But after data binding with AutoGenerateColumns=True I tried to clear Columns list and add new, but old autogenerated columns still there. There is an example on VB.NET of code for adding new column

reportGrid.AutoGenerateColumns = False
reportGrid.Columns.Clear()
Dim column As New GridBoundColumn
column .DataField = "field1"
column .HeaderText = "header1"
reportGrid.Columns.Add(column)

Columns.Clear() doesn't remove autogenerated columns, how can I remove them? Thanks

Answer 1

link to telerik website

this is the documentation on how to do what you are trying to do.

or check Grid.MasterTableView.AutoGeneratedColums collection.

Answer 2

According to telerik it is not possible to delete a Grid column which is already added in the Grid's Column collection. One suggestion will be to set its Visibile/Display property to false.
