Combo Box behaviour on Pop-UP

Hi, Pls find here in attached code. I am using pop-up container, with Windows combobox. On first click on Combo Box , it closes by itself. Pls. help. Regards Arya PopUpIssue_837.zip

Hi Arya, This is happening because the ComboBox doesn''t have focus when the popup opens. To correct this, please override the ShowPopup method in your PopupControlContainer derived class as follows: public override void ShowPopup(Point location) { base.ShowPopup (location); this.comboBox2.Focus(); } If you have any questions about this, please let me know.
