List Box With More Options

Need columns, colouring, icons etc? Use a List View

Creating a List Box

SelectionMode – Decide how many lines may be selected at a time by the user
MultiColumn – Not what you think! A multicolumn ListBox places items into as many columns as are needed to make vertical scrolling unnecessary.
Sorted – Allows the list to be automatically sorted

Erasing the contents of a List Box


Erasing Individual Items In A List Box

	while (lstMySelectOptions.Items.Count)
		lstMySelectOptions.Items.RemoveAt(0);	//(RemoveAt works on index number)

Adding items to a List Box

	lstMySelectOptions.BeginUpdate();		//Stop painting of the ListBox as items are added
	lstMySelectOptions.Items.Add("Item A");
	lstMySelectOptions.Items.Add("Item B");

Getting Currently Selected Item

	if (lstMySelectOptions.SelectedIndex >= 0)		//Ensure a list item is selected (-1 if not)
		UserId = lstMySelectOptions.SelectedIndex;

Selecting Items

   lstMySelectOptions.SetSelected(1, true);
   lstMySelectOptions.SetSelected(3, true);
   lstMySelectOptions.SetSelected(5, true);

Colouring Items

Use a ListView instead – gives full options over each item in the list.
