enter image description here

In brief: I want to load my form, then using a Background Worker fetch data from Database and set the DataSource of some comboboxes.
In DoWork event I fetch data, and in RunWorkerCompleted event I set the datasources. The problem is cross-threading issues. What can I do to resolve this?

I don’t understand why setting DisplayMember is OK but in next line, setting ValueMember throws an exception

    I think you got it backwards. The DoWork should be FetchData and DoWorkCompleted should be BindComboBoxes.
