Hi!
I'm having some troubleswith a custom web control.
When I use the web control "normally", that is, I throw it into the web page at design time, its viewstate is maintained along postbacks.
However, if I add this custom control at runtime to a place holder, it loses it's viewstate when the first (and the second, and the tirdm and so on) postback is fired.
The custom control is basically a DropDownList, and as I said, the problem is that that it resets back to it's first element everytime I postback. And i see this doesn't happen with "regular" dropdownlists, I mean, the ones that already come included with the language.
ˇif anyone can help me, I'd really appreciate it!

Can you save your state as a cookie? Or perhaps use a hidden field to save that information?
I think I may be able to implement one of those "solutions" but my question is, "shouldn't my custom control act like any other .net control???"
I was expecting to receive an answer like"you have to do this and your control will behave like any "stock" control"...
But i guess I could try your approach.
Thank you.
ps: if anyone has a better solution, one that involves my control behaving as it should, I'm still listening! =D
Ah, and I don't know either how to make a custom control whose class is not abstract, anyone knows how to do that, so I can instantiate my control at runtime, instead of leaving it laying on the page and referencing it at runtime?
I think I just solved it by using "LoadControl"! =)
