.NET Forum / .NET Framework / New Users / March 2006is it possible to define the order in which winform user controls load?
I have one control that absolutely must load before any other controls, due to some initialisation code within it. Is there a way of getting this control to load first? Moving the code from the load event to the constructor isn't an option to get around this issue. Any suggestions would be very gratefully received!!! Greg. The only option I see for now would be tweaking the designer code. My personal preference would be still to move this portion of code elsewhere (page_load ?). Some more details about why this is needed may help someone to make better suggestions.

I tried tweaking the designer code - the order in which the controls are loaded is not reflected to the order that they are being instantiated by my main form. So it would appear that the order in which they are loaded is determined by something else. I dont want to move the initialisation code into the constructor as that is called at design time as well as design time. designmode always returns false within the constructor and so can't be used to differentiate between design time and run time - and I need to avoid trying to create objects (part of my initialisation) at design time! Thansk again. Greg. If this order (controls would be "created" in a given order but not "loaded" in the same order ? how do you have checked this ?) is not under you control it looks like you are out of luck. You may still want to give some more details as it looks really an unusual requirement. My personal strategy would be rather to get rid of this requirement rather than trying to satisfy it. Also if it must do something special on other controls, it could be just implemented in a form you could inherit from. SignaturePatrice > Thanks Patrice. > [quoted text clipped - 12 lines] > > Greg.

If you absolutely require yours to load first then it is a bad design. It sounds as if you are trying to perform some operations on the other controls in the forms. If this is the case, I would suggest hooking your own controls 'ParentChanged' event. When the event is fired, then you can iterate thru the parent's control collection. You could also at that time hook the parent's ControlAdded and ControlRemoved events in order to catch controls that are added after your control. I haven't actually tried this but I think it should work. -mdb You could instantiate the controls dynamically after IntializeComponent; This would give you control in what order the controls are loaded.
