asp.net building controls
group:Custom control won't drag and drop to page
asp.net building controls:
I just downloaded source to a control from thecodeproject.com but I'm unable to drag and drop the control from my toolbox to the design mode of my ascx file. According to the docs, I should be able to do just that. Is there something special that I have to do to get a custom control to drag and drop into my page? Some sort of setting or something that I haven't included in the VS.NET option? Thanks, Andrea
Are you getting some kind of error message?
Here are some working examples of custom controls that can be successfully dropped from the toolbar: http://steveorr.net/articles/InheritAndExtend.aspx http://steveorr.net/articles/StreamingMedia.aspx -- I hope this helps, Steve C.

No, no error... When I try to drag and drop, the cursor turns to the no
sign as if it's not a control that can be dropped. It's the control from this article: http://www.codeproject.com/useritems/OverlibWrapper.asp Meanwhile I'll try the controls you suggest.

I tried the first link and it is not drag and dropping either. So maybe I'm
adding it to the toolbar incorrectly? Are there an instructions to add them?

I just noticed that all the system control are in the GAC... Do I need to
add them to the GAC? Andrea [quoted text, click to view] "Andrea Williams" <andreawil@hotmailIHateSpam.com> wrote in message news:%23oiI9UANFHA.3960@TK2MSFTNGP12.phx.gbl... > No, no error...

I wonder if the control is actually being added to the page, but it shows
no design time rendering. Check the underlying HTML for the control. It should look something like <cc:YourControlName runat=server ... /> -Brock DevelopMentor http://staff.develop.com/ballen [quoted text, click to view] > No, no error...

No, custom controls don't need to be in the GAC.

Nope, nothing is there. VS 2003 doesn't drop a thing. I can drag and drop
my User Web controls from my project into the page... And the control block appears in that case. So I'm adding the control to the toolbar by right-click the toolbar and selecting "Add/ Remove Items..." On the .Net Tab I browse, find the dll in the BIN/Debug folder and select it and click OK. That puts the item on the toolbar. When the page is in design mode, the control looks to be enabled. I click and drag it... When the drag goes to the page (in design mode), the cursor changes from the bow and pointer to a circle with a line through it (No sign). I drop it anyway and nothing happens. No control in design mode and not text in HTML mode.

Most of the time when this happens it is because your UserControl is
throwing an exception of some sort. There are a few occassions where this will just "happen" and creating a new web page or a new project usually solves it. In cases where it does not it is most likely because somewhere along the line the UserControl is throwing an exception. Most obvious things to look for are code references that might fail at runtiome because things like Server is null (thus a call to Server.MapPath in OnInit or in the constructor or OnRender would fail)
ok, I created a new project and it is dropping into the new project. I
tried adding a new page to my old project and it still was not working. My page layout is defualted to Flow instead of Grid, would that have anything to do with this issue? The new defualted to grid. So, assuming there's a problem with my project that makes the drop fail, what could it be? Where should I start looking? Or is it a bug in VS.net?

One of those wonderful mysteries of life.
