Forms Data Controls :: Error CS0103 Or CS0120 When Try And Call A Method From Another Page
Dec 4, 2010
I'm a beginner at this, sorry if I get the terminology wrong. I'm using Visual Web Developer 2010 Express with C# 2008 and .NET v4.0 to create a website which will have a database application.
I have a SQL Server table which contains some bit fields (FruitsEarlySpring etc). When I linked this to a GridView with SELECT only defined, the bit fields were displaying as greyed-out checkboxes. To replace these with something more attractive I used Item Templates with Labels instead of the Checkboxes with custom binding e.g. Tick(Eval("FruitsEarlySpring")) and this logic in the code-behind file:
[Code]....
The label text font family is set to Webdings so that the "a" displays as a tick (a 'check'?), and this works very well.
My problem is, I have a separate page which displays the same fields using a FormView and I want to display them the same way, referring to the same logic, but I can't seem to access the method. I get runtime error CS0120, "An object reference is required for the non-static field, method, or property 'APR2.Fungi.Tick(object)'
line Line 338: <asp:Label ID="EarSprLab" runat="server" Font-Names="Webdings"
Line 339: Text='<%# APR2.Fungi.Tick(Eval("FruitsEarlySpring")) %>'></asp:Label>
Before this I tried not qualifiying the method name and got error message CS0103, "The name 'Tick' does not exist in the current context". The code-behind files occupy the same namespace, and the class and method are now both public so I don't think it's a scope problem. I have searched this forum for similar problems and no, I don't have two master pages, or a duplicate set of files.
I am getting a CS0120 error when trying turn a button visible after checking some variables. In plain english, If AmmohelpSession.UserActions contains AmmohelpEnums.UserAction.ArticleEdit then turn the Edit button visible. Here is my comparison:
[Code]....
In the code behind for AmmohelpSession, a public class AmmohelpSession which contains a private variable: private HashSet<UserAction> _userActions; has been stated. In that same file, there is a public function for the UserActions that does a get or set method.In the code behind for AmmohelpEnums, we are setting byte variables to specific actions. Mine would be something like:
This error is baffling me. My webpage was working fine up until I added a label for testing to the page. Now when I try to debug the page, I get a error CS0103 for every item on my page that I try to reference in my "behind" code.
The .aspx page:
[Code]....
My errors are as follows:Error 1 An object reference is required for the non-static field, method, or property 'System.Web.UI.Control.Visible.get' 23 5 TRX-Support Error 2 The name 'LoginRoundPanel' does not exist in the current context 24 5 TRX-Support
I have tried deleting the designer and convering the page back to a web application, and this didn't help. I'm fairly new to ASP.NET & C#
Got a little dilemma I could use some guidance on. I'm trying to call an Interface method that resides in my Business Layer from within the template of a gridview in the same manner as below:
i have one method in master page and a label in same master page, and their is one method which changes text in label, and i want to call the same method in Master page from my Usercontrol.
I usually only write in ASP, so I am not very familiar with this script. Can anyone tell me how to how to request a querystring so I can use it to pull the image location. Like this.

I have a few custom composite controls that set their cssclass only when calling their ApplyStyleSheetSkin method.I worked around this by creating a function which recursively walks through all controls on a page and calls that method, but I was wondering if there isn't a way to do this automatically? (i.e. how do I tell the aspx page to call the ApplyStyleSheetSkin method inside the controls?
I am using the application.master of sharepoint server 2007 as the master page for my application. i want to call a custom javascript method( OnLoadFun) that i have put in the PlaceHolderAdditionalPageHead asp:content section surrounded within script tags.

I have created a simple ASP.NET Website in Visual Studio 2008. I have a static C# class (lets call it someClass) contained in a separate file in the App_Code folder. I call a method from that class in my page's code behind like so:
someVar = someClass.someMethod(someParam);
This compiles correctly in VS 2008 but when I move it over to my IIS server, I get the following error (CS0103): Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately. Compiler Error Message: CS0103: The name 'someClass' does not exist in the current context I have created a virtual directory for this website enabling 'Read', 'Run scripts (such ASP)', and 'Execute (such as ISAPI applications or CGI)'. I am not currently utilizing namespaces (as I thought I would not need to and I'm not sure how to use them properly). What am I doing wrong?

I have a problem when I try to pass in paramaters for a report in my report viewer. I have set up the ObjectDataSource and set the paramaters for 3 text boxes that are on the page. The only way I have found to set the paramaters for the report is the user must fill in the paramaters and hit the refresh button on the Report Viewer toolbar ,but I would like to have the user click a asp.net button insted. Is there anyway to call the refresh method from codebehind?
I have a page called AddNews.aspx and in codebehind a web method called AddNews(Parameters).. AddNews.aspx page is inherited from a master page.. So i used contentplaceholder. I have a button..It's id is btnSave.
