C# ToolTip Class

Introduction

The ToolTip control in Windows Forms is a small pop-up box that displays when you place your pointer or cursor on the control. Its purpose is to provide a brief description of the control in the Windows form. The ToolTip class is used to generate ToolTip controls and provide various types of properties, methods, events, and run-time control status.

ToolTip Class

In any container or control, you can utilize the ToolTip class. You may generate several tooltips for multiple controls with the aid of a single ToolTip component under the System.Windows.Forms namespace, the ToolTip class. 

In C#, there are two methods for creating a ToolTip in a Windows form:

• Design Time
  It's the simplest approach to making a ToolTip, as indicated in the instructions below:

1. Create a windows form:
   Visual Studio -> File -> New -> Project -> WindowsFormApp
    
2. Drag and drop the ToolTip from the ToolBox onto the form. When you drag and drop this ToolTip onto a form, it will immediately add it to the properties (called ToolTip on ToolTip1) of all controls in the current window.
   
    
3. After dragging and dropping, navigate to the ToolTip control's properties to customize ToolTip to your liking.
   

• Run Time
  It's a little more difficult than the previous way. With the help of the ToolTip class's syntax, you can construct a ToolTip control programmatically in this function. 
  The instructions below demonstrate how to set the generate ToolTip dynamically.

1. Create a ToolTip control using the ToolTip() constructor provided by the ToolTip class.

// Creating a ToolTip control
ToolTip t_Tip = new ToolTip();

2. After creating the ToolTip control, set the property of the ToolTip control provided by the ToolTip class.

// Setting the properties of ToolTip
t_Tip.Active = true; 
t_Tip.AutoPopDelay = 4000; 
t_Tip.InitialDelay = 600; 
t_Tip.IsBalloon = true; 
t_Tip.ToolTipIcon = ToolTipIcon.Info; 
t_Tip.SetToolTip(box1, "Name should start with Capital letter"); 
t_Tip.SetToolTip(box2, "Password should be greater than 8 words");
