Web Forms :: Programmatically Reference The Class Name In Code - Behind VB?
Jun 17, 2010
I am writing an application that does it's own logging in a SQL table. On each page, I statically assign this variable: Dim page = "page_01.aspx" I've noticed that page is ALWAYS equal to the name of the Partial Class of the code-behind + the suffix ".aspx" Is there any way to programatically set the string to equal the name of the Partial Class, so I don't have to statically code it on each page? Basically, I want to assign the name of the current class to a string, and append ".aspx" to it. Can I do this, or does that get lost in the compilation?

I am working on converting a project from C# to VB and am facing this weird issue. 1 page cannot compile and I get the reference error, but the weird thing is that the compiler shows the error as coming from ASP.NET generated code. Visual Studio shows me that error is coming from my ASPX page. I cannot seem to figure out why or where this error is occuring. Also if I take the inherits attribute out I don't get the compilation error. The code in aspx page is below:
i have 2 class file business logic layer in c sharp but my application is in vb.net ie my code (aspx.vb) file contains the code for th epage is it possible to reference the same csharp class files in the .aspx.vb file.

my MasterPage I have a label that reflects the name of the module that the user is currently in. I change the label text accordingly using the following ..
Instead of placing this method in the code-behind of every page, I want to put it in a single class and call it accordingly. I thought of using a static class but do not know how to reference the MasterPage.Can I use a static class? or do I place the method in the code-behind of one page and call Object.Method from the other pages?
I am attempting to access a textbox control on a master page from a code behind base class but having problems. I have 3 levels of master pages. m1.master is the master page for m2.master which is the master page for m3.master.m3.master has a textbox as shown below
I have a class (name PageBase) that is inhariting System .Web.UI .Page and all my .aspx page behind classes are inhariting this class. This way I have put some common things in PageBase class.
For showing errors I want to put showMessage funtion in PageBase as well so that I may have not put it in every page and it will easy to manage this way.
Probem is that how PageBase class will access a control which is in aspx page in its child class (child class of PageBase) .
I dont want to pass control as argument to function in parent class, is ther any other way ?
I have created an asp:listbox and in the cs file, I am trying to bind it to a datasource. However, I want to put in tooltips for each option so that when you hover over a multiple-listbox you will see the name of the item in both the listbox and the tooltip.The following code is what I have tried (which obviously will not work), which will just put a big tooltip for the "select" html tag, instead of the "option" tags individually.I think I need a loop, but I'm not sure how to add attributes to each element and the ASP documentation is no help. I bet it's an easy solution, but I can't figure out how to do it.
I have a div runing on server in which i programmatically add images. On post back, id like to get some attributtes from those images, but they are nowhere to be found. What am i doing wrong?
I'm getting an "Object Reference Not Set to an Instance Of An Object Error" in a Web User Control that I've created when referencing any control in the Code Behind. Intellisense reports that the control exists in the aspx, but whenever I build and run I get that error.

I'm reading a bit of Pro ASP.NET MVC Framework and following a few tutorials written in the book. In the very first tutorial, creating a MVC site for dinner (PartyInvites), I encoutered this problem. While I try to reference some properties from Model class, the compilation error occured. Eg. the following code failed.
[Code]....
and the error message
Compiler Error Message: CS1061: 'object' does not contain a definition for 'Name' and no extension method 'Name' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) I imported the Model folder into the controller too. I dunno what I'm missing here. Sorry, if it sounds a bit umm hard to understand cuz I just started picking up MVC this morning. Looking for any input.
I have an activex OWC11 Chartspace on my form. I wish to be able to access this object in my code behind page instead of scripting the code in the asp page. Has anyone any idea how to get a handle to the activex chartspace object from the code behind. I know how to create an OCW chart and then display it as a jpeg from the code behind page but the activex chart component offers more use with the chart opbect on the page rather than a jpeg?
then I would like to set the class for the li according to the controller value. How do I do that?
Something like: if controller == "home", then set the class for the li with the home id to active.
I just started learning MVC and am very new to the syntax. when you respond to this posting provide syntax, as I am coming from code behind background.
Why do we use the reference of abstract class (or base class) to create object of it's sub-class. eg: TextWriter is the abstract class for StreamWriter & StreamWriter.
