MutliColumn Listbox

[zoltan_ie]

How on earth do you added data to the different columns of a multi column Listbox?

Any example would help as I can't find any anywhere

A multi column list box has no vertical scroll bar.

When a new item is added which would normally cause a vertical scroll bar to appear, it is instead inserted into a new column to the right.

Try this : it's from MSDN and demonstrates the behaviour very well.

   // Add items to the ListBox.
   for (int x = 0; x < 50; x++)
   {
      listBox1.Items.Add(string.Format("Items {0}", x));
   }

   // Display items in columns.
   listBox1.MultiColumn = true;

   // Determine the width of the items in the list to get the best column width setting.
   int width = (int) listBox1.CreateGraphics().MeasureString(
      listBox1.Items[listBox1.Items.Count -1].ToString(),
      listBox1.Font).Width;

   // Set the column width based on the width of each item in the list.
   listBox1.ColumnWidth = width;

If you don't want behaviour like this then use a ListView in report mode instead.
