.NET Forum / Windows Forms / WinForm General / January 2007OnClick preceding OnEnter
VS 2005 w/SP1 / XP Pro w/all service packs One of our forms has a Tab-control onto which is dynamically added a number of other controls. When the added controls are ComboBoxes or CheckListBoxes, their OnClick event is fired before their OnEnter. For other controls on the Tab (e.g. ListBox) the events occur in the expected order -- Enter and then Click. On other forms where the controls are added to a Tab-control at design-time, the Enter / Click also occur in the expected order. Does anyone have any idea why on this form the Click (and MouseClick) event would precede the Enter event? -- // Lee Silver // Information Concepts Inc.

If I had to guess, it would be related to the differences between setting focus on those controls versus other ones. -- Bryan Phillips MCSD, MCDBA, MCSE Blog: http://bphillips76.spaces.live.com > Anyone have any thoughts on why OnClick would precede OnEnter? > [quoted text clipped - 12 lines] > > // Lee Silver > > // Information Concepts Inc. Bryan: In all cases we are setting focus by clicking on the control with the mouse. As a point of clarification... When I wrote OnClick and OnEnter I really meant the Enter and Click events; we are not overriding the the On*** methods. For a ComboBox the problem manifests itself as follows: The first time the control's selection-arrow is clicked nothing happens; the second and subsequent times click the selection-arrow causes the drop-down list to appear. The drop-down list should appear *every* time the selection-arrow is clicked. -- // Lee Silver // Information Concepts Inc. > If I had to guess, it would be related to the differences between > setting focus on those controls versus other ones.

Solution: In the Click-event, if and only if the Enter-event has not been entered, set the DroppedDown property to True. -- // Lee Silver // Information Concepts Inc. > Bryan: > [quoted text clipped - 39 lines] > > > > // Lee Silver > > > > // Information Concepts Inc.
