How to use XPCollection with LookUpEdit to show master and detail data

Answers approved by DevExpress Support

Hi,

This behavior occurs since LookUpEdit does not update the CurrencyManager.Position property value when an edit value is changed. To avoid this shortcoming, handle the LookUpEdit.EditValueChanged event in the following manner:

C#
void edit_EditValueChanged(object sender, EventArgs e) { LookUpEdit edit = sender as LookUpEdit; BindingManagerBase manager = edit.BindingContext[edit.Properties.DataSource]; manager.Position = edit.ItemIndex; }

Let me know if this solution is helpful.
