VS 2010 - String Sorting In Order Numerically

May 3, 2012

I have a list of strings lets say the items are like this:
item_1
item_2
item_4
item_10
item_8
item_11

If I do list.sort() I get the following
item_1
item_10
item_11
item_2
item_4
item_8
Somehow I need to get these in order numerically but I am dealing with strings not numbers.

Sorting Listbox Items Numerically In VB?

Jan 28, 2010

I need to sort the items in a visual basic listbox numerically, that is, I have a collection of numbers I would like to be sorted increasingly.

I tried to simply use the listbox's Sorted property, but found that it treated the numbers as if they were strings, that is, it would look at the first digit, then the second, etc. to determine the order. That meant that 13 would show before 5, for example.

I thought of dumping all the numbers into an array, soring the array, and then pushing them back to the listbox, but, honestly, I don't know how to go about the sorting. I figured the array would be useless, since the listbox already acts as a pseudo array.

Sorting Numerically With A Datagridview Bound To Xml?

May 20, 2011

I've been searching for days for a solution. I've scoured the internet and other forums and tried so many things at this point that I think my brain may explode.I receive a large XML file from a third party vendor. I have converted the XML file to a a dataset and use the dataset to fill a datagridview with a specific table. I do not have a schema from the vendor and the XML file does not contain any data type information. The datagridview populates fine but all columns are defaulted to type string. This presents a problem when sorting columns that should be numeric - they sort by string comparison instead of logically numeric. I've tried numerous ways to attempt to convert the datatable columns to integer to no avail.

Decimal Column In Datagridivew Is Not Sorting Numerically?

Mar 16, 2012

I have a datagridview which is bounded to a table m_table constructed in my code. A column named price has decimal type.

DGV.DataSource = m_table
DGV.Columns(columnPrice).ValueType = System.Type.GetType("System.Decimal")

All prices are in decimal. But I found that when clicking the column header of DGV, the price column is sorted like a string. For example:

9.0, 13.5, 8->13.5, 8, 9.0

But I want sort numerically, that is 8,9.0,13.5

I wonder why decimal type cannot be sorted numerically. How to achieve this?

Sorting Number Numerically In List View?

Dec 18, 2010

In 2007 I created a program that reads weather data into a listview. When a user clicks on the column header it fires off the column click event handler which calls the Sort Wrapper function. The Sort wrapper will re-order items either in ascending or descending order.

I have never been able to get negative integers to sort properly. I have created a stripped down listview program with a few numbers in the grid for testing. (see attached program zip file).When you run the program, click on the column header that says "Val" and you will see right away that the numbers do not sort correctly.

2010- Sorting A Set Of Labels Against The Previous Set In Order To Check The Answer And Accuracy?

Apr 23, 2012

I have a program which is made with 12 labels, the first set of six are randomly generated and the second set are values obtained from the first set and the user has to choose in ascending order the numbers on the first set.The values chosen will be trasferred to the second set and then with a "check" button that set of labels have to be rearranged and compared to the user input.If the user for example manage to choose the right order, he will obtained a 6 of 6 and he will recieve a message.My problem is on the rearrage and compare part.

The code I made is very simple but is not working, basically it only check if the next value is smaller that the previous and changed its back color according to the case.

Here the code:

'check button
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim Score As Integer
Score = 1

[code]....

I would like to have a correct rearrange of the numbers and introduce a message according to the accuracy of the user.

Sorting - Sort List(of String()) Using A Variable Index Into String() As Key ?

May 30, 2012

I have a List(of String()). I have written a custom comparer (implements IComparer(of string)) to do an alphanumeric sort.Is there a way to sort the List using a given index to determine which position in the String() to sort by? In other words one time I might sort by Index = 0 and another time by Index = 3. The length of all String() in the list is the same.For reference this question is similar to Sort List<String[]> except I am using VB.net and that question is hardwired to Index=0.

EDIT from OP's comments:I started simple with the non custom comparer but I am getting an error: expression does not produce a value. Not sure what I am doing wrong.Here is the code:

Public Shared Function SortListOfStringArray(ByVal ListOfStringArray As List(Of String()), ByVal SortByIndex As Integer) As List(Of String())
Return ListOfStringArray.Sort(Function(x, y) x(SortByIndex).CompareTo(y(SortByIndex)))
End Function
