I'm developing a Xamarin.Forms mobile application and few pages show an error:
Field _filedname is already declared
Though there is no other declaration of any field with the same name. I tried multiple names and still show the same error. Same on code behind.

I was adding a new Form to my program in visual studio, and I put in some basic components like panel, labels and PictureBox, when I got back to the code, it simply All forms had problems BC30469 with the description "Reference to a non-shared member requires a reference of object." and some like BC30925 with the description "Access specified in form "friend" does not match the access specified in "Public" in one of its other partial types." for all commands that reference other commands in other forms, and before to add this new form, there was none,
I undo the whole process of adding the form and it continues with the same errors!
I have spent many hours trying to solve this issue, I feel like I have tried almost everything I found online, so I will go about explaining the issue, and what I did.
Situation:
I am working on a web app. Added to the solution by opening a web site on a local IIS
Many of the aspx.vb files inside of it are having the error "Handles clause requires a WithEvents varaible defined in the
containing type or one of its base types" after pressing the play button at the top. (not present when rebuilding)
As soon as I click on the description to go to the error, all of these specific errors
Stuff I have tried:
I have tried VB silverlight for windows phone "Handles clause requires a WithEvents variable defined in the containing type or one of its base types", but it didn't work.
changing the inherits tag, as well as the autoeventwriteup in the page tag (<%# Page Language="VB" AutoEventWireup="true" EnableViewState="True" CodeFile="frmBatchEdit.aspx.vb"
Inherits="Administation_frmBatchEdit" Culture="auto" meta:resourcekey="PageResource1"
UICulture="auto" %>)
At this point I could use any help I can get. What is annoying me most is seeing 2000+ of these in my project, and then to make it all disappear I have to remove one at a time. The website itself is very old, and I am wondering if it has something to do with the age of it, because each time I change something in a file, it will start showing this error in the future.
Thank you for any help.
I just created a UserControl in my application, the problem I have is that every time I edit the code of UserControl I have to delete the UserControls already added to the GUI because it fails to compile.
The project / application is called Panel and UserControl called TimerPanel, which contains a couple of text boxes within a GroupBox.
The error reads
Type 'Panel.TimerPanel' is not defined.
The strange thing is that everything works OK until I edit the UserControl.
Like I said, if I delete the UserControl GUI, compiled and then added again to the GUI control, everything works OK.
I read somewhere on this forum that you must add a reference to System.Windows.Forms, and I did and it behaves the same.
What can I be doing wrong?
When you get that error go and build the project again, see if that fixes the issue (building a project again fixes lots of errors and when you add/change a user control is needed to use it)
I am trying to create a Windows Phone app that will take use a similar UI element in multiple user controls.
One user control is loaded by the main xaml and this user control consists of another user controls. The user controls are all in the same directory below where the main xaml exists.
I get an XamlParseException on the following line in my g.i.cs file for the nested control:
System.Windows.Application.LoadComponent(this, new System.Uri("/MyApp;component/UI/NestedControl.xaml", System.UriKind.Relative));
I think it is doubling the component/UI portions of the path as the parent user control already resides in this directory.
Does anyone know how to solve this?
This exception typically means that the XAML parser cannot find the referenced XAML, or that you have invalid XAML for your NestedControl class.
Without further code, it is hard to determine the root cause. I would suggest deleting these classes until your project compiles, then slowly adding them back again, compiling each time. This will help you identify where the problem lies.
Using ASP.NET 4.0, I'm creating an RDLC stream by instantiating a Microsoft.ReportingServices.RdlObjectModel.Report, setting the Code property, and returning the stream using the RdlSerializer.
Then I'm passing that stream to the ReportViewer like so:
ReportViewer1.LocalReport.LoadReportDefinition(rdlcStream);
If I don't set the Code property, I don't get any errors and the report displays properly, but when I set the Code property for a report that needs custom code, I get the below mentioned 'RequestMinimum' is obsolete error.
An unexpected error occurred while compiling expressions. Native compiler return value: ‘[BC40000] 'RequestMinimum' is obsolete: 'Assembly level declarative security is obsolete and is no longer enforced by the CLR by default. See http://go.microsoft.com/fwlink/?LinkID=155570 for more information.'.’.
This error doesn't occur using the Report Viewer control in a winforms app.
Has anyone seen/resolved this issue?
I do not know exactly the cause of this error, but in my experience, it was related with a simple copy and past from a expression from one cell to other cell inside the results table, all this after making changes in the layout and groups.
I recommend you delete any expression or formula, verify that your report is executed without any error message, and rewrite down all the expressions and formulas one to one, checking in every formula that your report open correctly.
That worked for me.
For me it was the page number in this line
<Value>=Globals!PageNumber + ' of ' + Globals!TotalPages</Value>
When removed everything goes right and i don't know why
Another option for those got this error and generate report markup.
Likely one of you <Value> tags starts with "=" sign and if this is not an expression you need to use EvaluationMode="Constant".
