how do i know which portion of a ToolStripSplitButton is enterd?

Hi, all

I have a ToolStripSplitButton and I wanna show different visual effects between the event that themouse enters the button portion and the mouse enters the dropdown arrow portion. I tried to use b.ButtonSelected and b.DropDownButtonSelected to differentiate these two things, but it doesn't work. When the mouse enters any part of the whole split button, these two properties are both true. How do I tell which portion of the button is entered? I thought of override the OnMouseEnter method but don't know how to get the Mouse position in such an event. Could somebody help me out? Thank you!

This ought to solve your problem:

private void toolStripSplitButton1_MouseMove(object sender, MouseEventArgs e) {
evalMouse(sender as ToolStripSplitButton, false);
}
private void toolStripSplitButton1_MouseEnter(object sender, EventArgs e) {
evalMouse(sender as ToolStripSplitButton, true);
}
private void evalMouse(ToolStripSplitButton ctl, bool entered) {
Point pos = ctl.Owner.PointToClient(Control.MousePosition);
pos.X -= ctl.Bounds.Left;
pos.Y -= ctl.Bounds.Top;
Console.WriteLine("{0}, {1}", pos, entered);
}
