I recently began having a problem with a VS 2008 C# project where the primary form will load and paint correctly in the VS Form Designer the first time the project is loaded. But if I then do a Build, go to the code display, and then return to the form, I get the error "The designer loader did not provide a root component but has not indicated why". It also says "There is no stack trace or error line information available for this error".
I've search these forums for the error, but have only seen it reported for VS2005. In those instances, the only suggestion was to go thru the generated form code and comment out sections of InitializeComponent() trying to find the error by process of elimination. My form is a very complex set of nested tabs used as wizards and my InitializeComponent method is nearly 3,000 lines, so I'd love to find another way to approach the problem.
Are there any fixesor patches that might affect this? Does anyone have another way to tackle this? |

Allow me to add one more note; though I do not know whether it is meaningful. Since my original post, I've seen others with this problem who mentioned it had happened after dropping and design-time binding a dataset on their forms. This also began with me after an editing session in which I added a dataset and bound it to a gridview at design time.

I too have just experienced it in a simple little VB208 (Express) application. It did not occur "as soon as" i placed a bound object on the form. I'd had bound objects on the form for some time. I've just bee editting the columns of a datagridview which is bound to a datasource in the dataset. I do noticek, however, that the datagrid recognizes a 'derived' field I define in the source query for that datatable; but the datatable in the dataset view does not show that field. So something is clearly out of 'synch'.
I was hoping 2008 would calm some of the ADO issues, not further inflame them. I'm beginning to re-design my courses for our "all-Microsoft" solution developmjent program, as I do every time there's a new approach to database processing in Visual Studio, so I've been pretty busy these few years.
I hope this additional observation may help; someone diagnose and fix this problem soon.

I have the same anoying problem.
I'm using Devexpress and ReSharper but I don't think any of them causes this problem.
The form appears properly at runtime but I get the same error at design time.

I am using the same combination of DevExpress and ReSharper, and also get the message occasionally. No problem at runtime.
After Closing/Reopening the project in Visual Studio, problem is always resolved, but it comes back at some time later.

Hmm strange. I'm now getting this exact same problem and I'm also using DevExpress, which seems to be a common theme here. I'm not however using ReSharper.

Okay, I'm using Visual Studio 2008 Professional w/ Service Pack 1 and I'm coding in C#.
I've been having this problem in my project for a while but I simply ignored it because it wasn't a big deal to me at the time. All I had to so was like build the project while on the designer and it will come back. Now I'm going back and forth between the code and the designer and it's really really really annoying I have to either close the designer tab and reopen or build the project after I change something in the code.
I've seen other people talk about this problem all around the net but so far I haven't come up with a solution. What I thought was the problem I eliminated as a possible cause. Because I had a control that was in the designer and I took it's code and moved it to a void in the main code so I could control it. Doing that left the "Private this.this.this.this name" I thought that because that was left in the designer code it was causing problems. I commented that out and closed and reopened the project and I'm still getting the error. So now I'm completely stumped.
Thanks guys!

I'm am getting this on a project right now and I never have before. The project is almost brand new and is using a data set, data bindings, data grid views, and DevExpress controls.

I am running into the same problem more often than I would like to. I am also running Resharper but I believe the issue is coming from using a custom winforms control. Doesnt seem to happen on pages without the control Im using. |

Glad to see its something microsoft is actively working on.  .

I had the same problem with DevExpress, here what I found; http://www.devexpress.com/Support/Center/p/Q50880.aspxDidn't work for me, may be for someone else it works...
" This isn't a question really but more of a solution I wanted to be sure that was in your knowledge base. My application contains mostly Developer Express controls. At some point I started getting the following message:
"The designer loader did not provide a root component but has not indicated why."
The form showed fine during design time but when I started debug the form would disappear from designer and be replaced by only the error message and no other failure information. After doing a bunch of stuff then doing a lot of searching, I found somewhere that if you get this error then delete all of the files in your bin/debug, bin/release, obj/debug, and obj/release directories in Solution Explorer then start debug again. It fixed the problem for me and hopefully will for others also. "

I have same problem - using DevEx and Telerik controls.
I implemented Ozmanovski suggestion from the DevEx forum... it seems to work... so far...
I also found a quick work around when it happens is to just Close the Designer (not whole project) than go to
Solution Explorer and open it again... it always opens fine at this point... and sooner or later while building
it will crash the design window again.
But so far clearing the bin and obj dirs seems to work.
Thanks,

BRiddle,
Did you ever find a solution to this. I've tried everything and the designer still won't show the form!
Thanks

Same problem with VS2008 vb.net.
After much anger, I found this way:'Rebuild Solution'every time it happens.
Hope this help. |

Hi,
I ran into the same issue, it has nothing to do with 3rd party components. I resolved the issue by checking the sequence of constructors in the generated code, identifying the "broken" sequence, deleting the offending component (in my case two table adapters and a databindingsource) and reattaching the databindings. Be sure to check your "load" method of your form.
Hope this helps,

Hi all,
Just my two cents.
I had this error as well in VC++ 2008 Express. I followed the advice given earlier whereby I closed the designer window and then re-opending it. The error messages changed to something more useful.
In my case I did an ignore and found that I have some small inconsistent charting setting in a 3ed party package called TChart which I quickly fixed and everything seems fine now.
