Problems in designing Form

HI ...
I am using Microsoft Visual Express . While designing a form I faces some problems.
I dragged Combo Box Control , assigned String Array in overrided
OnLoad method. The combo box was blank. (style drop down list). Then i deleted that control , added new Combo box , same code and it worked well.

In the mid of the form design , when I ran my application, all of a sudden , all the controls were in disabled state. Nothing helped to enable them though Enabled Property was true. I deleted the form and designed again.

pl explain me , where I made mistake ?
and also how to use resources from .resx file while attaching images to button.

Thanking u ,

It sounds as if you have made a parent control disabled. if you have a panel or group box or even the form's Enabled propery set to False this will happen.

Obviously you haven't supplied any code so it is difficult pin pointing your exact problem

Thank you HannesTheGreat sir . I checked all items for Enabled property but I forgotten to check Main Form and Group Box .. That could be the reason. Thank you
