I have an application where i load all my lists at startup then i bind them as datasources for comboboxes. I have found that if i bind a collection to 2 comboboxes then the selected item is kept the same on both comboboxes. Any reason why the selected item is being tracked through both?

Do i have to clone the collection or is their some settings?

• Could you please post the code snippet where you are binding?

• WinForms or ASP.Net?

• Binding to a EntityCollection directly or via other control (LLBLGenProDataSource, some BindingSource)?

• LLBLGenPro version?

winforms,llblgen v2.5,dotnet2

    Me.cmboUser.DisplayMember = "Name"
    Me.cmboUser.ValueMember = "UserId"
    Me.cmboUser.DataSource = comm.tblUserEntityCollection
    Me.cmboUser.SelectedIndex = -1

    Me.ComboBoxActivityAssignedUser.DisplayMember = "Name"
    Me.ComboBoxActivityAssignedUser.ValueMember = "UserId"
    Me.ComboBoxActivityAssignedUser.DataSource = comm.tblUserEntityCollection
    Me.ComboBoxActivityAssignedUser.SelectedIndex = -1

thanks

Me.cmboUser.DataSource = comm.tblUserEntityCollection

You might try binding to a view of the collection instead.

Me.cmboUser.DataSource = comm.tblUserEntityCollection.CreateView()

Arschr is right, you have to bind via a new view to each combobox. If you don't do that, and bind the collection to the comboboxes, the same defaultview is bound to both comboboxes. If you create a new view each time, the binding is different per combobox
