Question

I need to insert a star shape into a string which will be assigned as the text of a TreeNode. Is this possible?

Each TreeNode has different levels and can be annotated by these stars. Some nodes have a single star, some have two, and some have no stars. The star(s) will always appear at the end of the text string. For example:

SU450**

You have to use a Font which contains the character you want to display.

Mostly, Arial Unicode MS will work.

Here’s an example using ‘BLACK STAR’ (U+2605)

void Main()
{
    var w = new Form();
    var t = new TreeView();
    w.Controls.Add(t);
    t.Dock=DockStyle.Fill;
    var star = "\u2605";
    t.Nodes.Add("good: " + star);
    t.Nodes.Add("great: "+ star + star + star);
    t.Font=new System.Drawing.Font("Arial Unicode MS", 13f);
    w.Show();
}
