Listview control not sorting correctly, is it becuase it's a numer

[=?Utf-8?B?UHVjY2E=?=]

Hi, I'm using vs2005, .net 2 for C# windows application.
One of my column on the Listview control has numericstring. Other columns
are sorting correctly except this one. It seems to be sorting the 1st
numeric char at the beging of the string. How do I resolve this problem?
Thank you?

You could implement the IComparer interface & use an ArrayList to store the
contents that are used to populate the ListBox, now pass the comparer when
using the Sort method.

public class MyComparer : IComparer
{
/*
Less than zero
x is less than y.

Zero
x equals y.

Greater than zero
x is greater than y.
*/

public int Compare(object x, object y)
{
int nx = Int32.Parse((st ring)x);
int ny = Int32.Parse((st ring)y);
return nx.CompareTo(ny );

}
}
I see that your listbox is a numeric string, so you can implement your custom
logic in the Compare method above.

Thank you for the help but I don't know what do you mean by "pass the
comparer when using the Sort method"? ( I assume the Sort method of the
Listview is what is referred here). What am I doing with the arraylist? Do
I call the compare method to sort out the array?
Thanks.

Check out MSDN @ http://msdn2.microsoft.com/en-us/lib...er(vs.80).aspx.
The comparer example I gave was is pretty close to the full blown example
listed in MSDN. You will need your custom comparer to do comparisons in a
way that is different from the default behavior. The snippet I gave was actually
for a ListBox rather than a ListView
