Accessing Controls From Separate Classes
Jun 23, 2010I have an ASP.NET Web Site I am creating in Visual Web Developer 2008 Express using Visual Basic as the language. It is actually a rewrite-with-mods of an existing ASP script and I'm trying to chew what I've bitten off. I created my page with a text box (txtOutput) on it and since the end product is very complex, and it's generally good practice to separate like functions, I have created 4 separate classes in the App_Code section.
My main page is Sync.aspx and has a code file Sync.aspx.vb with it.
One of my code files is SyncDatabases.vb and in it I have created
Public Class SyncDB
In that class I have created some routines such as
Public Function ReadMSDB(ByVal SQLString as string) as Boolean
In this routine I want to put information in my text box txtOutput on the main form (the default - Form1).
My problem is that if I try:
Form1.txtOutput.Text = "Hello world"
or just
txtOutput.Text = "Hello world"
it says Name 'Form1' (or 'txtOutput') is not declared. I am sure I am missing something simple but have no clue what it is. I assume it's the fact that the write command is in a file (class?) outside the file (class?) containing the page itself but I don't know how to address it properly.

Accessing Objects From Other Classes?
Sep 7, 2010In ASP.NET I have a form that has a Textbox named txtOutput and a button. In the main file.aspx.vb I can call a function from the button handler and in that function I can have
txtOutput.Text = "Some Message"
with no problem. I have a bunch of functions in several other classes. For instance I have a class named AbleCommerce that does some database functions. These functions are called from my main class. In those functions, however, I have no visibility of txtOutput. All of my classes are, unfortunately, in the default namespace which I understand is not optimal but didn't seem to impact this issue.
I know this is an easy one I've just not understood properly but it has me stumped. My gut says that I probably need to pass the Textbox object to my "other class" but can't for the life of me figure how.

C# - Class Structure With LINQ, Partial Classes, And Abstract Classes
May 17, 2010I am following the Nerd Dinner tutorial as I'm learning ASP.NET MVC, and I am currently on Step 3: Building the Model. One part of this section discusses how to integrate validation and business rule logic with the model classes. All this makes perfect sense. However, in the case of this source code, the author only validates one class: Dinner.
What I am wondering is, say I have multiple classes that need validation (Dinner, Guest, etc). It doesn't seem smart to me to repeatedly write these two methods in the partial class:
[code]....
This doesn't "feel" right, but I wanted to check with SO to get opinions of individuals smarter than me on this. I also tested it out, and it seems that the partial keyword on the OnValidate method is causing problems (understandably so). This doesn't seem possible to fix (but I could very well be wrong).
Accessing Form Control From A Master Page
Sep 29, 2012I have a master page, sub master page and content page. The master page has a form control which both masters can access by name alone:
Code:
<form id="form1" runat="server">
The content page contains a contact form, with the form tags removed as they conflict with the form tags on the master.
What I want to do now is access form1 on the content page so I can change its properties for use in the contact form. I'm not sure if this is how its done in ASP? Anyway, here's how I've tried to:
Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim f As Control = CType(Master.FindControl("form1"), Control)
f.Action = Request.Url.ToString()
f.Name = "contactForm"
f.Method = IsPostBack
End Sub
C# - Can Base Classes See The Protected Fields Of Derived Classes
Aug 11, 2010I don't know if this has to do with how FindControl works or how scope works. But my base class is having a hard time seeing the fields of child classes. Currently I'm planning have the derived class set a property in the base class, but there are a lot of derived classes, so that isn't a very attractive solution.

C# - Control Accessing Event Handler In Web Form Class?
Mar 11, 2010I have a Custom WebControl. Inside this control I add a button and I want it to access an EventHandler that is on the WebForm where the control is included. The handler handles with controls from the WebForm, so it has to be there. I could probably manage to take the button out of the control, but it would be better to keep it on the control, for organization sake.

C# - Accessing The Form Collection In An IHttpModule Causes Event Handler Not To Get Called On Default Page
Mar 18, 2011I've created a simple sample site to demonstrate the issue. In it, I have a Default.aspx Page that has a button on it:
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<p><asp:Button OnClick="ButtonClick" Text="Button" runat="server" />
</p>
<asp:Label ID="output" runat="server" />
</asp:Content>
The code behind just sets the label text on the button click:
protected void ButtonClick(object sender, EventArgs e)
{
output.Text = "Button Click!!";
}
I then have an IHttpModule that gets called for every request:
[code].....
And now it's broken again! So to make a long story short, just by accessing the Form collection on the request in the IHttpModule, I somehow screw up the PostBack, and the event never gets fired.
Map Model Classes To ViewModel Classes Or Aggregate Model Classes In ViewModel Classes
Dec 15, 2010I'm curious as to what people consider better practice, between duplicating model structure in the view model and using a mapping tool to move data between the two, or aggregate the model inside the view model, i.e. have a property on the view model class that is a reference to the actual model. Which is considered a better approach in general?
