i have 2 tables

tblcall linked to tblcustomer 1:1

i fetch the tblcall entity ( with prefetch to get the related customer)..this works fine.

i also fetch the customers which binds to the combo box fine..but the default customer is not being selected? How do i get it to select the correct customer?

I have tried the following

    cmboCustomers.DataBindings.Add("SelectedValue", oCall, "TblCustomer")
    Me.cmboCustomers.DataSource = _customers
    Me.cmboCustomers.DisplayMember = "Name"
    Me.cmboCustomers.ValueMember = "CustomerId"

Is this a win app or a web app? Anyway I think you can set the selectedValue after databinding, on DataBound event?

first bind, then select value.
