ExamGuru IT/.Net Guru : System.Windows.Forms.ColumnClickEventArgs Class [Articles]

Every so often, while happily coding along in .NET, I’ll run into an object with a few methods that just don’t make sense. The .NET ListView object was just one of those. In VB6 it was a piece of cake to sort by columns in a ListView. All you did was pass it the index of the column you wanted to sort by. Now, in .NET, things have gotten a little bit more complicated. The gist of the new method is this: you must create your own custom class that implements the IComparable interface and overrides the Compare Function with your own code. Then take that class and set the ListViewItemSorter property of the ListView equal to it. Take a look at the custom class below and then see how it is used in the column click event of the ListView object.

If you want to sort on the first column of a ListView, simply click the Sorting in the properties Window and choose Ascending or Descending as a value. If you want to do sorting in all the columns of a ListView, you need to write custom sorting using the ListViewItemSorter property. This property allows you to assign the property to an instance of a custom class that implements the IComparer interface.
