Almond Croissant 4
Mixed Salad(v) 20 No Onions

I need to develop a page in my applicaiton like the image for the user lists.
I need to get the list of users under a group and need to show likw this.
i have list<player> with duplicates.
i need to create another list<player> from the first list <player> with out any duplicates.
I want to remove duplicates from this list:
List<Dictionary<string, object>> val = new List<Dictionary<string, object>>();
It does not work if I apply Distinct() in this way:
List<Dictionary<string, object>> result = val.Distinct().ToList<Dictionary<string, object>>()
Update: Problem is now solved. I used the MySQL union command to read table from the database.
I have a Method that returns 4 records like this.
Name: Test1
Year: 2010
Value: $1000
Name: Test2
Year: 2010
Value: $1000
Name: Test3
Year: 2011
Value: $2000
Name: Test4
Year: 2011
Value: $1000
I need a way to get the unique years just ( 2010, 2011) rather than all 4 years, rest of the data could be duplicates.
Here is the method:
public List<TestCosts> GetTestvalues(string testid)
{
List<TestCosts> testlist = Testscores.List(testid);
return testlist;
}
Most of the examples of removing duplicates I saw have a list of one item only but in my case I have 3 items per record and I need to loop through each record, find the duplicate years, remove them and then return the distinct list of years along with the other data.

I need the 1 since it's a foreign key in another table. For the life of me, I can't get this to work like this.
I have a list view control. Each row within it has a rowid and a textbox where a note(user enters relevant info to that particular record) is entered. On a paging event I store the rowID and the note text in a generic list for retrieval if the user pages back later on. Goal here is to keep the text the user has entered. (see the code below)This generic list does in fact get populated correctly when I go to the next page currently. I can see this in Visual Studio. So now, when the user goes back to the first page I want to run a test within my Listviews ItemDataBound event. I want to see if the row ID being tested is part of the generic list. If so, I then want to take the corresponding note that is also within the list and bind it to the text box. However, I don't know how to write the correct conditional for this and how to bind the textbox if the conditional evaluates to true.

View 7 RepliesI have a generic list which contains a class called Parameter. Parameter contains 2 integers, ParamType and ParamValue. A generic list is built containing a small number of values List<Parameter> myList I have created a function which passes in 2 parameters. These are passed individually but are used to create a new Parameter within the function. The Parameter is tested against myList, and if it is found removed. In order to do this I have used the remove function, the syntax being:
myList.Remove(new Parameter(ParamType, ParamValue));
The remove isn't working and at present I'm using LINQ to do it.
I notice that my generic list is maintaining only one item, i declared it in the aspx.cs page f one of my forms. I am assuming that each time the page is reloaded when I add an item the list is redeclared. How can I stop that?
