How To Create A Model Class To Validate The Form Fields
Dec 9, 2010I am beginner to MVC. I have created a View with dropdownlist, text box and text area. I didn't create a strongly typed view because these fields are not generating from the database.

How to create a Model class for these fields?
Here is my view looks like.

Web Forms :: How To Create A Form To Create An Ascx Page And Code Behind For It
Sep 15, 2010Is is possible to build a form, accept parameters and from THAT construct a new .ascx page AND the code behind for that page? What I'm proposing is having some code snippets that just need parameters added and can then be used to create a web user control that can be added to existing pages. This .ascx file would be a real file after creation, not dynamic every time.

View 10 RepliesCreate New Class For Each Procedure?
Jul 23, 2010All I want to do is learn how to create a class procedure. And then. How to call it. As an example, A + B = C is the procedure. I would create a class. Right? Then do I name the procedure and put it in the class? Or create a new class for each procedure? Then I would want to, on a local level, substitue values for A & B to return C. So, if the public procedure exists, how to I call it? I know that this is really simple stuff, but I need examples to be simple.

Sep 24, 2010I am trying to create a pageBase class where I can dynamically pull data from the database and display it on a web page. Each page I specifically set an ID for the sql query which pulls back the information such as page title and page text.
my problem is that I can't seem to pass the information captured from the query to the page. I get problems such as can't convert string type to literal and I need to declare a new keyword to an object.

C# - How To Create Instance Of A Class Only Once
Apr 4, 2011A instance of a class is created in the partial class of an aspx page.Under page_load or button click method I'm trying to set the value to the class. but when each postback takes place new instance is created and I'm losing the previous value.
public partial class DatabaseSelection : System.Web.UI.Page
{
DBProperties dbpro;
Metadata obmeta;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
dbpro = new DBProperties();

C# - Cannot Create UserControl In Class
Jan 26, 2011My ultimate goal is to create a UserControl in a class in my App_Code folder and render the html from that into a string.
The rending of HTML can be done using this example I believe:
How do I get the HTML output of a UserControl in .NET (C#)?
My Question:
I created my user control
public partial class Controls_MyUserControl : System.Web.UI.UserControl
I've registered it in my web.config
<add tagPrefix="UC" src="~/Controls/MyUserControl.ascx" tagName="MyUserControl" />
I can reference this on a page just fine
<UC:MyUserControl ID="MyUserControl1" runat="server" />
Yet when I try to create an object of this control type in a class (in my app_code folder) it doesn't allow me.
Controls_MyUserControl dummy = new Controls_MyUserControl();
The potentially strange thing is when I put this code into a code behind of a page, it works.
what I need to do to have the usercontrol to be able to be created in my class in the app_code folder?
My guess is, is that I need to reference the control in a "using" statement at the top, but I'm not sure what that'd be.
It's not in a namespace to my knowledge (at least there's no namespace, in the code behind of the actually user controls). Though I'm not sure if it inherits one from the System.Web.UI.UserControl.

View 1 RepliesHow To Create Partial Class For UserControl
Feb 24, 2010I am using Visual Studio 2008 with .Net 2.0
I am maintaining and old application in ASP.Net and it has one CustomGridView control with 4000 lines of code. I see that in that file only, when I try to modify any code the IDE does not respond quickly as it does for other files. I thought of creating partial classes for the same but it seems that VS is not reconginzing the new partial class. I am trying to use the variables from the old partial class and it is not able to reconize any variable or method.

JavaScript - Create Css Class On The Fly In Codebehind
Aug 4, 2010I have a search page that is used in multiple places with multiple 'themes' throughout my site. I have a few divs that can have their background color changed based on a radio button selection (whether they are enabled or not). I can do this just fine by changing the css class of the div on the fly with javascript.
However, these themes could potentially change, and the background color is grabbed from a database when the page is created. Right now I do this in the C# codebehind:
string bgStyle = "background-color:" +theme.searchTextHeaderColor +";";
OwnerSearchHeader.Attributes.Add("style", bgStyle);
In the Javascript I need to change this color to make it look disabled, and when the user clicks back to this div I need to re-enable it by changing it back to its original color. But since I only knew this color in the code-behind, I don't know what it was in the Javascript.
So my thought was to create a css class in the resulting HTML page when the page is loaded with the background color I need. Then I could simply switch from the divEnabled and divDisabled class in the javascript. But I'm not exactly sure how to do that.
