I want to get an object typed properties values. Here is my code:
Type tip = Type.GetType(pair.Key.GetType().ToString());
object uretilenNesne = Activator.CreateInstance(tip);
uretilenNesne has correct type but I want to access uretilenNesne's properties values.
I'm using MVC, and in the controller, I'm using a linq to objects query which returns an anonymous type:
var results = from ... select new { ... };
I then pass this information to an untyped view:
return View(results);
I try to iterate through the data in the view:
<% foreach (var entry in Model)%>
...
<%: Html.Encode(entry.MyProperty) %>
However, I get a RuntimeBinderException: 'object' does not contain a definition for 'MyProperty'. However, oddly, if I hover above entry with the mouse, it does actually have MyProperty in the popup window, and the value is what I would expect,(apparently, the Visual Studio IDE knows what type it is).I can get around this problem by using a linq query which uses an explicit type and a parameterless constructor of the form:
IQueryable<SearchResult> results = from ... select new SearchResult { ... };
and creating a view model class which encapsulates the SearchResult data, which is then returned to a strongly typed view. However, I don't understand what the problem is with the first method.
Prior to using a ViewModel, I could easily pass the "soon to be edited" object directly to the view without needing to fuss over setting individual properties etc as the View conveniently accepted the Employee type directly..
[HttpGet]
public ActionResult EditEmployee(int? id)
{
EmployeeRepository ER = new EmployeeRepository();
Employee SomeEmployee = ER.GetEmployee(id.Value);
if(SomeEmployee!=null)
return View(SomeEmployee);
But now I'm using a ViewModel with DataAnnotations attributes applied over the top of various properties for validation purposes. Which creates a problem.. After fetching the "soon to be edited" object from the db, setting the ViewModel's values is suddenly a whole lot more complicated. I can't simply pass the retrieved object straight to the view, as the View now expects the VMEmployee type instead. I would like to be able to do something like:
[HttpGet]
public ActionResult EditEmployee(int? id)
{
EmployeeRepository ER = new EmployeeRepository();
Employee SomeEmployee = ER.GetEmployee(id.Value);
if(SomeEmployee!=null)
return View(new VMEmployee(SomeEmployee));
All paths seem to lead to a huge constructor which manually sets the values of each individual property. But I never had to do that before when I wasn't using a ViewModel. Model binding was a blessing! My objects also have complex child objects, which my form is also collecting values for, so this would be a huge/verbose task against DRY principals. I don't even really want to use a ViewModel, but am forced to because I need two different DataAnnotations rule sets for different validation scenarios applied to the same object.
All I want to do is be able to have two different DataAnnotations rule sets for different scenarios. I.e. public-facing www site vs internal-facing admin site. DataAnnotations doesn't seem to be flexible enough to easily cater for this common need. I've tried AutoMapper, but it throws an error saying it can't map my object types, I suspect because Employee was auto-generated by LINQ to SQL. What is the most elegant way to achieve this while sticking to DRY principals?

I'm working on an application that uses an approach to localization where they just call a translate function for every piece of text on a page. It leads to a lot of redundant code that looks like this (psuedocode):
function page_load():
translateControlText(control1, language);
translateControlText(control2, language);
translateControlText(control3, language);
translateControlText(control4, language);
translateControlText(control5, language);
translateControlText(control6, language);
translateImageAlt(image1, language);
100 more lines of this on a single page
The application is massive, so I don't have the opportunity to rewrite the translation logic. However, I think I could just loop through all of the controls on a page, check their type, and translate the appropriate property. At least then I would just have to call 1 function per page, and then throw it in a base page or master. However, I probably wouldn't want to translate certain things, such as table cells. Regardless, there is an attribute called Localizable that is on many properties such as Control.Text and Image.Alt. I'd like to be able to get a list of every string on the Page that is stored in a Property marked Localizable. Is this possible? Is this possible without reflection?
I have two different classes, and would like to (for example) alter the text of a label control contained in one class using the other. At present I experience the following error (e.g.):
"ProjectName.PageName.Protected WithEvents ControlName As System.Web.UI.HtmlControls.HtmlGenericControl' is not accessible in this context because it is 'Protected'."
All the subroutines in my PageName class begin "Protected Sub...", however even if I change these to "Public Sub..." this does not fix the problem. How do I achieve this? Also, are there security implications to not protecting subroutines?

1: I have a .html file that has some markup with some placeholder tags.
[code]...
4: PersonInfo.aspx is literally empty since I am injecting html from code-behind.
When the PersonInfo.aspx is called the html-template markup with appropriate values in the placeholder will be displayed. Also there are chances I would like to send the final markup in an html email (though that is not part of the question as I know how to email).
Is this the best way to fill values in my html-template or is the any other better alternative?
Note: This is a very simple sample example. My class is very complex involving objects as properties and also my html template have 40-50 placeholders.
So code in my step 3 will need 40-50 Replace statements.
Using the properties as defined in a class, how about can I put them into the ParamArray parameters argument of my function. The code as follows:

Quick question here. I'm sure it's possilbe, just can't get it to work.
I've got a gridview. In have a gridview. The gridview is bound to a list of my custom class. The class exposes a link to an image as well as the image's height and width. I have a Image Control in the gridview. I've bound the Image Url to the correct property. Now, I'd like to bind the height and width properties as well. But everytime I do that I get the following error:
Cannot create an object of type 'System.Web.UI.WebControls.Unit' from its string representation '"<%#Bind("GetImageHeight()")%' for the 'Height' property.
Here is an example of the tag:
<asp:Image runat="server" ID="imgProduct" ImageUrl='<%#Bind("ImageUrl")%>'
Height="<%#Bind("GetImageHeight()")%>" Width="<%#Bind("GetImageWidth()")%>">
