listbox

I use TableLayoutPanel for all my elements in a form. I use Dock Fill to autosize a TextBox and a ListBox. TextBox fits perfectly in a cell of the TableLayoutPanel but not a ListBox. It autosizes by item height. How to delete this gap between the bottom of the ListBox and the bottom of the form? I know I can set the height of the ListBox by a certain value (e.g. item height in the ListBox is 16, 16 * 10 elements= 160, 160 will fit correctly), but is there any other solutions? I'm using C#.

Is there a way to make some of the items in a ListBox readonly/disabled so they can't be selected? Or are there any similar controls to ListBox to provide this functionality? ListBox doesn't have support for that. You can bolt something on, you could deselect a selected item. Here's a silly example that prevents even-numbered items from being selected: private void listBox1_SelectedIndexChanged(object sender, EventArgs e) { for (int ix = listBox1.SelectedIndices.Count - 1; ix >= 0; ix--) { if (listBox1.SelectedIndices[ix] % 2 != 0) listBox1.SelectedIndices.Remove(listBox1.SelectedIndices[ix]);

I have a page with two ListBox controls. The page contains a list of items based on the item's category. There is a header for a category, followed by a ListBox containing all items for that category, then another header followed a list of items for that category, etc. The issue I'm having is that each ListBox scrolls independently. I want the whole page to scroll (which it does), but not each individual ListBox. The ListBox controls grow automatically to their content, so there is no need to have them scroll. Is this possible?

I have tried CSS: overflow: auto. It doesn't work. Any way to achieve it? Do I need to create my custom control as I have seen it on ASP.NET forum?
