Question

Guys, I have a windows form with a panel control and inside the panel control are several other controls with a System.Windows.Forms.Tooltip attached to them. How can I iterate through each tooltip and set the Active property of the tooltip to false? Tooltips, unlike other controls, are not actually controls. So I had this:

foreach (System.Windows.Forms.Control ctrl in this.pnlControl.Controls)
{
    if (ctrl.Name.StartsWith("tt")) // since all my tooltip names start with 'tt'
    {
        System.Windows.Forms.ToolTip TipControl=(System.Windows.Forms.ToolTip)ctrl;

        TipControl.Active=false;
    }
}

This does not work though. It gets an error because the ToolTip control is not inherited from System.Windows.Forms.Control. Any ideas?

EDIT:
Okay Guys. I probably didn’t go into enough detail to get the answer I needed. My problem is, I’m taking all the controls in my panel and moving them to a different panel. Once they are switched over, the tooltips are still attached to the controls, which is what I want. However I have no way to deactive or reactivate them once I move them since the form and the original panel no longer exist. However, I found a solution which I will post here.

How to add tool tips for two buttons? The correct way is NOT creating two instances of ToolTip in this way:

 ToolTip tt1 = new ToolTip();   //or you can create one in the designer
 tt1.ToolTipTitle = "test";
 tt1.SetToolTip(button1, "caption1");
 ToolTip tt2 = new ToolTip();
 tt2.ToolTipTitle = "test2";
 tt2.SetToolTip(button2, "caption2");

Remember that a ToolTip instance and a control are not one-on-one related. The right way for this example is:

ToolTip tt1 = new ToolTip();   //or you can create one in the designer
tt1.ToolTipTitle = "test";
tt1.SetToolTip(button1, "caption1");
tt1.SetToolTip(button2, "caption2");

To remove the tooltip of button2, use:

tt1.SetToolTip(button2,string.Empty);

For your case,we can use

foreach(Control c in this.Controls)
{
   tt.SetToolTip(c,string.Empty);
}
