Binding issue

[DarkConsultant]

Hi,

I am binding a combobox to a List(Of KeyValuePair(Of Integer,String)) using the code ...

Contacts is my list of kvp.

With cmbContacts
.Items.Clear
.DisplayMember = "Value"
.ValueMember = "Key"
.DataSource = New BindingSource(Contacts, Nothing)
End With

This works OK, populating the combobox with all of the KVP values.

However, I am not sure of the second BindingSource arg of Nothing (this is how it was on the example I found on the web).

When my code hits the BindingSource command I get three System.ArgumentNullException's. Although these do not affect the workings I am at a lost to explain them and would like to eradicate them.

Any ideas?

TIA

David

Try this:

[red]Dim bsContacts As BindingSource
bsContacts = New BindingSource
bsContacts.DataSource = Contacts
[/red]
With cmbContacts
 .Items.Clear
 .DisplayMember = "Value"
 .ValueMember = "Key"
 .DataSource = [red]bsContacts[/red]
End With
