suspended databinding (winforms)

Hello I had my application working fine until something got changed affecting data binding. Here is a simple code on Form_Load: ComboBox objListControl = new ComboBox(); ArrayList aList = new ArrayList(); PopulateArrayList(aList); // populates list so aList.Count > 0 ln 0: objListControl.DisplayMember = "Text"; ln 1: objListControl.ValueMember = "Value"; ln 2: objListControl.DataSource = aList; After this code is executed objListControl.Items.Count == 0 even aList has some elements. I have Syncfusion.Windows.Forms.Tools.DockingManager instance placed on the form. If I delete it from the form then objListControl.Items.Count == aList.Count right after ln 2, otherwise it is 0; objListControl gets populated with items after form is activated anyway, but in case when DockingManager is on the form it is kind of posponded, it is not happening right after ln 2; If I use ComboBoxAdv everythign looks good. Does anyone know possible explanation for this? Thanks for help Konstantin
