你可以在combobox的selectedindexchanged去动态加载tooltip,例如: private ToolTip toolTip1 = new ToolTip();// Set up the delays for the ToolTip in selectedindexchanged event toolTip1.AutoPopDelay = 33000; toolTip1.InitialDelay = 1000; toolTip1.ReshowDelay = 0;// Force the ToolTip text to be displayed whether or not the form is active. toolTip1.ShowAlways = true; // Set up the ToolTip text for the Button and Checkbox. toolTip1.SetToolTip( yourComboBox, yourComboBox.Text );
private ToolTip toolTip1 = new ToolTip();// Set up the delays for the ToolTip in selectedindexchanged event
toolTip1.AutoPopDelay = 33000;
toolTip1.InitialDelay = 1000;
toolTip1.ReshowDelay = 0;// Force the ToolTip text to be displayed whether or not the form is active.
toolTip1.ShowAlways = true;
// Set up the ToolTip text for the Button and Checkbox.
toolTip1.SetToolTip( yourComboBox, yourComboBox.Text );
这个才是我想要的效果.
