Type	Description
DevExpress.XtraEditors.Popup.PopupLookUpEditForm	A DevExpress.XtraEditors.Popup.PopupLookUpEditForm object that represents the control’s popup window. null (Nothing in VB) if the popup window has not been opened yet.

Remarks

At runtime, the control’s popup window can be opened with a click on the control’s dropdown button, or in code using the PopupBaseEdit.ShowPopup method. After the popup window has been opened for the first time, you can use the GetPopupEditForm method to get access to the popup window object. If the popup window has not been opened yet, the GetPopupEditForm returns null (Nothing in VB). Typically, you will be calling the GetPopupEditForm method in the PopupBaseEdit.Popup event handler to get access to the popup window after it has been opened. In the event handler, you can adjust the popup window settings, or handle its events. See the code below.

C#

private void lookUpEdit1_Popup(object sender, EventArgs e) {
    DevExpress.XtraEditors.LookUpEdit edit = sender as DevExpress.XtraEditors.LookUpEdit;
    if (edit != null){
        DevExpress.XtraEditors.Popup.PopupLookUpEditForm popupForm = edit.GetPopupEditForm();
        // ... 
    }
}

VB.NET

Private Sub LookUpEdit1_Popup(sender As Object, e As EventArgs) Handles LookUpEdit1.Popup
    Dim edit As DevExpress.XtraEditors.LookUpEdit = TryCast(sender, DevExpress.XtraEditors.LookUpEdit)
    If edit IsNot Nothing Then
        Dim popupForm As DevExpress.XtraEditors.Popup.PopupLookUpEditForm = edit.GetPopupEditForm()
        ' ...
    End If
End Sub
