Question

I have two DropDownButtons (ToolStripDropDownItem) – btn01 and btn02

I would like btn02 to be a sorted list of the items of btn01.

I’ve currently got.

List<string> list = new List(btn01.DropDownItems); //  I want to create a list
list.Sort();
btn02.DropDownItems = list; // sorted list should be btn02 items.

First and third line have syntax errors.

Answer 1

Something like this would work.

It’s not the prettiest code, and can be reduced down a number of lines, but I wanted to make sure it was clear.

var unorderedList = new List<ToolStripItem>();
for (int i = 0; i < toolStripDropDownButton1.DropDownItems.Count;i++ )
{
    unorderedList.Add(toolStripDropDownButton1.DropDownItems[i]);
}

var orderedList = unorderedList.OrderBy(l => l.Text).ToList();
toolStripDropDownButton2.DropDownItems.AddRange(orderedList.ToArray());
