Binding Collection to DataGrid without showing all columns

[Orlando Cavadini]

Hello

I bind a collection of objects with Type AB (Class AB) to a DataGrid control
as following:

Public Class AB
Private m_AA As Integer
Private m_AB As Integer
Private m_AC As Integer

Public Property AA() As Integer
Get
Return m_AA
End Get
Set(ByVal Value As Integer)
m_AA = Value
End Set
End Property

Public Property AB() As Integer
Get
Return m_AB
End Get
Set(ByVal Value As Integer)
m_AB = Value
End Set
End Property

Public Property AC() As Integer
Get
Return m_AC
End Get
Set(ByVal Value As Integer)
m_AC = Value
End Set
End Property
End Class
....

Private m_list As New Collection
....

Dim c As AB
c = New AB
c.AA = 9
c.AB = 99
c.AC = 999
m_list.Add(c)
c = New AB
c.AA = 8
c.AB = 88
c.AC = 888
m_list.Add(c)

....

DataGridSections.DataSource = m_list

The DataGrid shows three columns AA, AB, AC with two rows of data. That
works fine. But now, i'd like to show only the columns AB and AC. What do I
have to do to get this result. Everything I tried failed.

Many Thanks for your help in advance

Hi Orlando,

Try to create a DataGridTableStyle, set its MappingName to "AB" (or leave it
empty - I really don't remember how to set MappingName properly when binding
it to a collection). Then, create two instances of DataGridColumnStyle and
set their mapping names to "AA" and "AC" (or, maybe, "AB.AA" and "AB.AC").

All these preparations should take place before calling the SetDataBinding
method on the grid.

P.S. The table styles and the column style can be created visually with the
TableStyles collection designer and the GridColumnStyles collection
designer.
