I have multiple toolstrip controls in my application and was looking for a way to hide them all at once.
E.g.
allToolStrips.Visible = false;
instead of
toolstrip1.Visible = false;
toolstrip2.Visible = false;
...
toolstripn.Visible = false;
I'm using C# if it matters.
easy one
foreach(Control ctrl in this.Controls)
{
if(ctrl.GetType() ==typeof(ToolStrip))
ctrl.Visible=false;
}
