List View Backcolor Resetting To None After Sort?
May 3, 2011
ive added a special color for some items into a listview, that was the only reason i picked up a listview over a listbox btw, anyways when i sort the items into that listview the items backcolor simply does not exist anymore, is there anyway i can still sort the items out and avoid this problem?
The only way i know right now is to add loops and numbers as reference and then setting those numbers as colors reference, then erasing them and add the backcolor, this is not viable to performance at all

how do you sort the data by columns in a list view, for example, clicking the title of the column to sort by ascending order.

when your resetting a form is it possible to deselect or not keep high lighted the item that was previously selected from the last entry. I know how to clear the text boxes but the items in the list boxes stay highlighted. Is it possible to get back to the initial setting of having nothing selected as when you first start debugging?

I have a List(Of T) storing a list of Custom classes called Advertisement. Each advertisement contains 3 properties, Year, Make and Model. I need to sort the list By Year, then by Make and then by Model. I have a property in the Advertisement class called Vehicle which returns a formatted string with the Year Make Model like 2007 Toyota Tacoma and ive been sorting on that but its not working how I thought it would. Basically I want to sort the list by Year (decending; lowest year first) then sort by the Make and Model (in alphabetical order) Is that even possible? Here is the code ive been using.

I'm having a bit of a 'brain doner' moment here
I have a list of Objects. Each of these Objects contains a list of other Objects (pseudo code) :-
Private Structure Object1
dim Name as string
dim ListOfObject2 as List(Of Object2)
[Code]....
I need to sort the list of Object1 by the Value in Object2. I have a comparison class which sorts Object2 by its Value nicely.

I am using vb.net2010. (express)
I am currently writing a bit of software for myself and need guidance.
I have a datagridview on a form with a date column. (column0)
I am trying to sort this by date desending but it will only sort by the day (dd) and not the whole date (dd/mm/yyyy) which leaves the months and years unsorted.
(example of output):
#1 - 01/03/2012
#2 - 02/01/2010
#3 - 03/02/2011

I have been told " Make sure the Date column is a date type and not a string " which i have taken as the access database column type. I have set this as Date but it still won't sort the column in datagrid view by the whole date.

What would be the fastest way to sort a list that contains a list of objects, based upon another list? An example follows:Say I have multiple lists of employees. Each individual list has a common property value, say "Department". So I have a list of employees, in one list they all have the department string value of "Sales". In another list all the objects have a department value of "Finance". These lists of employees are then contained in a list which holds them all.
I have a second list, which should drives the sort order of the employee lists. The second list simply contains a list of strings like, "Finance", "Sales", "IT" and so on. I'd like my lists of customers to be sorted in the order of "Finance", "Sales", etc.I'm using VB.NET in .NET 2.0

We have a generic List(Of Product) that must be sorted on two or more properties of the Product class.
The product class has the properties "Popular" numeric (asc), "Clicked" numeric (desc), "Name" string (asc). In order of naming the properties we want the list to sort.
How can it be sort with an lamba statement? If have found to sort the list based on one property.

In .NET, the Generics Lists have a sort function that accepts IComparer or Comparison. I'd like to sort just part of a list. Hopefully I can specify the start index, count of elements to sort, and a lambda function. It looks like you can only use lambda functions to do this if you're sorting the entire list. Is that right or did I miss something?

This is my first time posting here although I have been lurking for quite some time. I'm stuck with a problem I have seen before and never solved: I have a long list (~23,000) of alphanumeric strings that I'm reading into a List(of String) from a text file, and then sorting. When I iterate through the list after sorting, it appears to be correctly sorted EXCEPT that the element that was originally at the beginning of the list is now at the end (and it should be somewhere in the middle after the sort)Here is a sample input:
PRE1-PRE2_00015648
PRE1-PRE2_00015649
PRE1-PRE2_00015650

I have looked, unsuccessfully, for how to sort a list of strings alpha numerically. The .Sort() method sorts it like so:
abc,abc1,abc11,abc12,abc2,abc21,abc22
I don't want it sorted that way, I want it sorted like so:
abc,abc1,abc2,abc11,abc12,abc21,abc22
