Code:

CallTypes = New BusinessObjects.CallTypeCollection
CallTypes.es.Connection.Name = "SQLCLP"
CallTypes.LoadAll()

Code:

        Me.uxCallTypes.DataSource = Nothing
        Me.uxCallTypes.DataSource = CallTypes
        Me.uxCallTypes.DisplayMember = BusinessObjects.CallTypeMetadata.ColumnNames.Calltype
        Me.uxCallTypes.ValueMember = BusinessObjects.CallTypeMetadata.ColumnNames.CallTypeID
        Me.uxCallTypes.SelectedIndex = -1

and i have this databinding:

 
Code:
        Me.uxCallTypes.DataBindings.Add(New Binding("SelectedValue", entity, 
              BusinessObjects.CallRequestMetadata.PropertyNames.CallTypeID, True, DataSourceUpdateMode.OnPropertyChanged))

The problem i have is that i can have multiple copies of the same form open at once, 

so whichever value is selected in the most recently changed form is then selected for 

all other instances of the form since they are using the same datasource.

I know i can create a collection local to each form instance, but don't want to have to incur  

the overhead of loading it each and every time.

How can i accomplish different selected values on different instances of a form? 

Code:

        Me.uxRoute.Visible = False
        Me.uxRoute.DataSource = Nothing
        Me.uxRoute.DataSource = RouteCollection
        Me.uxRoute.BindingContext = New BindingContext()
        Me.uxRoute.DisplayMember = BusinessObjects.RouteMetadata.ColumnNames.RouteName
        Me.uxRoute.ValueMember = BusinessObjects.RouteMetadata.ColumnNames.RouteID
        Me.uxRoute.SelectedIndex = -1
        Me.uxRoute.Visible = True
