Error: Multiple controls with the same ID

N

Nathan Sokalski

When I view any page in my application a second time, I recieve the
following error:

[HttpException (0x80004005): Multiple controls with the same ID
'TitleBanner:_ctl0' were found. Trace requires that controls have unique
IDs.]
System.Web.TraceContext.AddNewControl(String id, String parentId, String
type, Int32 viewStateSize) +313

calcViewState) +201

calcViewState) +263
System.Web.UI.Control.BuildProfileTree(String parentId, Boolean

System.Web.UI.Page.ProcessRequestMain() +1608

If I close the browser and Visual Studio, and then reopen and rebuild the
application I can look at one page in the application one more time, but
then I recieve the error again. What can I do to prevent this error from
occurring? If there is any other information that might help figure out the
problem, I will be happy to give it to you. Here is the entire error page I
recieve:

I had what appears to be the same problem about two weeks ago. For some
reason, when I dynamically moved an HtmlTable from one container to another
(Page into PlaceHolder), the runtime dynamically generated a name for one of
the Table's children. It took a little while to track it but basically if
you recursively iterate through the controls collections of the controls on
your page (or, in your case, the controls in TitleBanner), and Trace.Write()
the control IDs and Type, you should be able to track it pretty effectively.
Once you find the "problem child", give it a name and you should be OK.

I believe I already know who the "Problem Child" is (the user control
TitleBanner has very few controls in it to begin with). However, giving it a
name would not be an acceptable solution in my case because it is a control
(or set of controls, actually) of which there may be 1, 3, 10, 50, or any
amount, meaning I cannot give them all static names because I will always
need a different number of the controls. I think the real solution (if I can
figure out exactly how to do it) would be to remove the previously existing
control with that ID from memory, which seems to be what happens when I
close the browser and Visual Studio and then rebuild the application. Any
ideas? If you want me to send you the code for the user control, let me know
and I can either attach it to a newsgroup message or email it to you.
Thanks.

Go ahead and send it to me ([email protected] - remember to remove
"remove"). I'll take a look at it this afternoon.

When I view any page in my application a second time, I recieve the
following error:

[HttpException (0x80004005): Multiple controls with the same ID
'TitleBanner:_ctl0' were found. Trace requires that controls have unique
IDs.]
System.Web.TraceContext.AddNewControl(String id, String parentId,
String type, Int32 viewStateSize) +313
System.Web.UI.Control.BuildProfileTree(String parentId, Boolean
calcViewState) +201
System.Web.UI.Control.BuildProfileTree(String parentId, Boolean
calcViewState) +263

calcViewState) +263
System.Web.UI.Control.BuildProfileTree(String parentId, Boolean
calcViewState) +263
System.Web.UI.Page.ProcessRequestMain() +1608

If I close the browser and Visual Studio, and then reopen and rebuild the
application I can look at one page in the application one more time, but
then I recieve the error again. What can I do to prevent this error from
occurring? If there is any other information that might help figure out
the problem, I will be happy to give it to you. Here is the entire error
page I recieve:
