MVC :: How To Get The IDictionary<Int32, String> Values On The POST Action
Apr 1, 2010I am working with MVC2 and one of the view model's properties is IDictionary<Int32, String>.
This is not to be changed on the view. But when the form is posted back I would like to still get those values.
Can Html.Hidden store this property values?
How should I do this so the model still gets the IDictionary<Int32, String> values on the POST action?

Best Practices For Using MVC With A Dictionary-like Model?
Feb 11, 2011I'm about to begin an ASP.NET MVC project and I'm not sure how to approach an aspect of the design. Basically, there is a user site and an admin site. In the admin sites, administartors design a form and send an e-mail link out to a handful of people. When the users click on the link, they are sent to the form.
Essentially what I'm wondering is what are the best practices when the model resembles looks more like a dictionary than a table?
In other words, instead of:
CREATE TABLE FormResponse (ResponseId, FormId, UserId, FirstName, LastName, BirthDay, Comments)
...containing 1 row per complete response
It's more like:
CREATE TABLE FormResponse (ResponseId, FormId, UserId, QuestionId, Value)
...containing 4 rows. 1 for the FirstName, 1 for the LastName, 1 for the BirthDay, and 1 for Comments.

MVC :: Modify The Routes Dictionary?
Feb 16, 2010 how to do routing. My problem basically relates to "logged in" and "logged out routes" and having both as "/".
i.e. I have home/index for logged out user which appears as "/" but this has got me confused as to how I can have home/home for logged in user and still have "/".
I keep getting 127.0.0.1/home/home
I could modify like 127.0.0.1/home - but I want it like "/". My confusion relates to the fact that the "/" [127.0.0.1/] is bound in the routes collection to home/index.
how I can modify the routes dictionary (which will be binded ONCE at the start) so that the "/" can be shared for logged and non-logged users ?
C# - Display Dictionary In ListBox?
Jan 10, 2011I've got a little problem with displaying my Dictionary in ListBox.
public static Dictionary<String, List<String>> MyDict = new Dictionary<string,
List<String>>();
...
if(MyDict[value1] == null){
List<String> Temp_List = new List<String>();
Temp_List.Items.Add(sth);
MyDict[value1] = Temp_List;
}
else if(MyDict[value1].Count < 4){
List<String> Temp_List = new List<String>();
Temp_List = MyDict[value1];
Temp_List.Add(sth);
MyDict[value1] = Temp_List;
}
and I'd like to display in Page_Load (after logging) a ListBox which will have List from MyDict for this login. Eg.
Login is : sally
And list contains of: she, no, then
And after sally logging I'd like to see result like this:
she
no
then
and I cannot use BindingSource
C# - Bind A Dictionary To A Gridview?
Jan 7, 2011Is it possible to automatically bind a Dictionary to a Gridview? The closest I've got is:
Dictionary<string, myObject> MyDictionary = new Dictionary<string, myObject>();
// Populate MyDictionary here.
Grid1.DataSource = MyDictionary.Values;
Grid1.DataBind();
This binds the properties in myObject to the gridview, but I'd like to get the key as well. If it's not possible, is there an alternative, e.g. use a repeater?

C# - Storing Dictionary In Session?
Jan 29, 2011How do you create a dictionary of objects in the session? More specifically, I have a list of objects: MyList stores MyObject as the result of a linq query with the date as a parameter.
List<MyObject> Mylist;
MyList = GetObjects(TheDate);
Now I'd like to store MyList in the session object in a dictionary with the date as the key. When the page needs a MyList for a specific date, first search the dictionary and if it's blank for that date, get the data from the GetObjects query and store the result in the dictionary in the session.
