ListBox Sorting issue (inaccurate)

Question

I am having a problem with sorting a multi-column ListBox. For simplicity, let's say I only have 3 columns: Id, Score, and TotalPoints. I have implemented a Compare method from the IComparer interface that looks like this:

 

public int Compare(object x, object y)

{

int compareResult;

ListViewItem listviewX, listviewY;

// Cast the objects to be compared to ListViewItem objects

listviewX = (ListViewItem)x;

listviewY = (ListViewItem)y;

// Compare the two items

compareResult = ObjectCompare.Compare(listviewX.SubItems[ColumnToSort].Text, listviewY.SubItems[ColumnToSort].Text);

// Calculate correct return value based on object comparison

if (OrderOfSort == SortOrder.Ascending)

{

// Ascending sort is selected, return normal result of compare operation

return compareResult;

}

else if (OrderOfSort == SortOrder.Descending)

{

// Descending sort is selected, return negative result of compare operation

return (-compareResult);

}

else

{

// Return '0' to indicate they are equal

return 0;

}

}

 

The sorting is inaccurate though. For example, let's say I have 3 rows, and the Scores are 10, 11, and 2. When I sort the column, it displays 10, 11, then 2...not 11, 10, 2. I am pretty sure it has something to do with the number of digits in the string, but I have no idea how to resolve it. For the most part the sorting works, just this little kink. Any help would be greatly appreciated.

 

Thanks
