Delete button inside DynamicTemplate in GridView

Hi!

I need to add a delete button to my GridView and wire up the onclick
event to a sub in my vb.code. The grid itself are created in the
codebehing - I have no aspx file that I can use for this.

Here's my code:

Protected WithEvents roleList As New GridView

'create templatefield column for role
Dim roleNameColumn As New TemplateField()
roleNameColumn.HeaderTemplate = New
DynamicTemplate(ListItemType.Header, "Roles")
roleNameColumn.ItemTemplate = New
DynamicTemplate(ListItemType.Item, "Role", False)

'add columns to the gridview
roleList.Columns.Add(roleNameColumn)
