Custom properties don't show at design time?

Posted on 2008-10-18
Last Modified: 2013-11-26
I am building a website in ASP.NET, and I use WebUserControls heavily. Most of the webusercontrols have custom properties, declared public in the code-behind. Some of hte properties are bindable, some aren't, all of them are public.

How come only SOME of the time I can see those properties in design-mode in Visual Studio? I can always set them in the source code, but sometimes they won't show in the properties window, and sometimes they will. And sometimes, only a couple of them show and a third one isn't there.

i think you have to give the property the suitable attribute like <Browsable(True)> _

I didn't realize you had to explicitely specify. I've put that into some of my properties now.

But... it's still not working. And it was JUST working for this control! I built the webusercontrol, put the properties in, looked at it in another page - everything was visible from design mode - ran the project, and now when I go back.... it's gone! And it won't come back. These properties DO specify the  Browsable attribute.

... man what the heck is going on here?

Ooh, it just came back. I added a fifth parameter and now suddenly all parameters are visible from design view. Screenshot attached (note - the webusercontrol looks like a hyperlink but it's actually a webusercontrol with a hyperlink inside of it)

But the properties don't show on my other web user controls. This is very strange.

Okay, after playing with it a bit, I think your suggestion was correct. Perhaps I just needed to restart ASP.NET.

It seems the custom properties disappear if I go into the code directly and add attributes to the tags myself. Maybe when you custom edit it like that you lose the ability to see it in design mode.
