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.

Ordered Dictionary Loses Value
Oct 3, 2011I am building a "query tool" so I am creating queries on the fly using DropDownLists (DDLs) to select table and field names. I have selected a Ordered dictionary to retain the association between field name and data type which I need to build my query string, to insert # for dates and quotes for strings. (I don't know that I could parameterize this process without creating a virtual nightmare of complexity) I am building the content of the field DDL in the onChange event of the table DDL using a function DDL_TableNames_SelectedIndexChanged() that returns a DataTable of selected fieldnames. Because I ran into so much trouble trying to include the field type in this process, I separated the two and am now using the ordered dictionary to remember what data type each of the selected fields is.
The problem lies in the fact that the ordered dictionary loses its value in subsequent Postback operations. So it populates on Postback, but resets after that since when I try to use the contents of the ordered dictionary it has no values.
Code:
'Dim global OrderedDictionary variable
Dim dicFieldNameType As New OrderedDictionary()
Protected Sub _DDL_TableNames_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DDL_TableNames.SelectedIndexChanged
Dim vTableName As String
