Title: Automatically resize ListView columns to fit their data in C#

ListView columns

It's actually pretty easy to automatically resize ListView columns to fit their data. If you set a ListView column's width to -1, it automatically resizes to fit the data it contains. If you set the width to -2, it resizes to fit its data and its column header.

This example displays buttons that let you set the ListView's column widths to 100 pixels, -1, or -2. The program uses the following SetListViewColumnSizes method to set all of the column widths at once.

// Set the listView's column sizes to the same value. private void SetListViewColumnSizes(ListView lvw, int width) { foreach (ColumnHeader col in lvw.Columns) col.Width = width; }

This code simply loops through the ListView control's columns and sets their values to whatever value was passed into the method.
