bind combobox

My combo box is populated in th ecodebehind using the cboBox.items.add("ProjectName")

In xaml, I have set the selectedvaluepath to the ProjectID

My listbox populates the names of the employees using a datatable which is populated from the database.

Question:
Why does the combo box not show the relevant item (ProjectName) for the name I select in the listbox?
Thanks

'Cause you add just one item with the text "ProjectName" to the combobox.

Use the displaymemberpath to project name.
