In Windows Forms, the ToolTip represents a tiny pop-up box which appears when you place your pointer or cursor on the control and the purpose of this control is it provides a brief description about the control present in the windows form. The ToolTip class is used to create ToolTip control and also provide different types of properties, methods, events and also provides run time status of the controls. You are allowed to use a ToolTip class in any container or control. With the help of a single ToolTip component, you are allowed to create multiple tooltips for multiple controls. the ToolTip class defined under System.Windows.Forms namespace. In C# you can create a ToolTip in the windows form by using two different ways: 1. Design-Time: It is the easiest way to create a ToolTip as shown in the following steps:

2. Run-Time: It is a little bit trickier than the above method. In this method, you can create a ToolTip control programmatically with the help of syntax provided by the ToolTip class. The following steps show how to set the create ToolTip dynamically:

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

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

Step 2: After creating 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");

Example:

CSharp

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Windows.Forms;

namespace WindowsFormsApp34 {

public partial class Form1 : Form {

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

Label l1 = new Label();

l1.Location = new Point(140, 122);

l1.Text = "Name";

this.Controls.Add(l1);

TextBox box1 = new TextBox();

box1.Location = new Point(248, 119);

box1.BorderStyle = BorderStyle.FixedSingle;

this.Controls.Add(box1);

Label l2 = new Label();

l2.Location = new Point(140, 152);

l2.Text = "Password";

this.Controls.Add(l2);

TextBox box2 = new TextBox();

box2.Location = new Point(248, 145);

box2.BorderStyle = BorderStyle.FixedSingle;

this.Controls.Add(box2);

ToolTip t_Tip = new 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");

}

Use the ToolTip control in Windows Forms. Review ToolTip properties.

ToolTip makes interfaces more intuitive. We add the ToolTip control to a Windows Forms application, which provides useful contextual hints to the client. We use Visual Studio to easily add, modify, and present ToolTips.

Add. First, to add a ToolTip control to your Windows Forms application, you need to open the ToolBox panel in Visual Studio’s designer. Then, open the «All Windows Forms» pane and find ToolTip. Double-click the ToolTip icon in the panel.

In the Visual Studio designer, there is a gray tray near the bottom of your Window. This area shows controls that do not appear inside your Windows Forms. Some dialog boxes will appear here. Your ToolTip control will as well.

Overview. Here we look at an overview of the ToolTip control in Windows Forms. First, many examples on ToolTips will show you the C# code to add them directly. However, this isn’t necessary in many programs.

Instead: We can use the designer to create all the ToolTips. This may be easier to maintain.

In Visual Studio, each control, such as Buttons and TextBoxes, will acquire a «ToolTip on toolTip1» property when you add a toolTip1 to your designer view. You can access this property in the Properties pane to set the tool tips.

Text. Here we add a ToolTip to a Button control in Windows Forms. Let’s add a Button named button1 to your Windows Forms window in the Designer. Please click on the button1 so it is focused.

It will be surrounded by the resizing boxes. Now open the Properties pane and make sure the Properties icon near the top is selected. Scroll down to the ToolTip on toolTip1 row, and add some text.

Next, you can run your Windows Forms application and hover your mouse over the Button control. You will see that you now have a tool tip on the button. You can apply this technique to most controls.

Infotips use sentence case and ending punctuation. In other words, you want your ToolTip (also called Infotips) to be a short, grammatical, and declarative sentence. Use an ending period.

Note: In the first screenshot on this article, the ToolTip uses the short declarative sentence «This is the tooltip you added.»

Also: It might have been better for the ToolTip to have the word «tooltip» capitalized with Pascal case.

Methods. It is possible and sometimes useful to write ToolTip code in C# code. If you can avoid this, however, it is best. Often, ToolTips that use IsBalloon will need to have custom C# or VB.NET code.

Tip: The Show method forces the tip to be displayed. The Hide method forces a ToolTip to disappear.

And: The Get and SetToolTip methods let you assign tooltips programmatically to controls.

Properties. Here are my notes on the properties available in the Visual Studio designer for the ToolTip control in Windows Forms. I have done work with ToolTips in C# code, but this is not usually necessary.

Tip: You can change the Active property, the color properties, the icon and title properties and the balloon property.

Property

Active property. This allows you to specify if the ToolTip is available to be opened or shown. When you set the Active property, the ToolTip is not immediately shown. Instead, it is enabled to be shown later.

AutomaticDelay property. This property allows you to specify the number of milliseconds after the user hovers over the ToolTip before it is shown. This isn’t worth changing in most programs.

But: AutomaticDelay could be useful in certain programs where accessibility is a requirement.

AutoPopDelay: This property lets you specify how long in milliseconds a ToolTip will remain on the screen if the mouse is frozen.

BackColor and ForeColor property. You can set the background and foreground of your ToolTip. It is usually best to avoid changing these. If you have a serious alert to display, a ToolTip isn’t the right control.

However: In some cases a different shade of light blue or pink can really enhance the impression of the ToolTip.

InitialDelay and ReshowDelay. These attributes let you specify the exact delays in milliseconds. Normally, these are best left with their default values, as the defaults are sensible.

Note: Unless you have a specific reason for changing these, you are probably going to hurt the usability of your program.

ToolTipIcon. ToolTipIcon and ToolTipTitle allow you specify an image to display on the tooltip, and a title to display. The title will be displayed in bold font at the beginning of the tooltip, on a new line.

Animation. The UseAnimation and UseFading properties let you specify the visual effects used on your tooltips. Windows XP and Windows Vista allow users to specify animation preferences in the Control Panel.

Tip: It is best to leave these to their default, so the user’s preferences are always applied.

IsBalloon. You can specify a balloon tip with the IsBalloon property. My experience is that balloons are poorly implemented and challenging to get exactly right. The balloon positioning is unpredictable when attached to controls such as TextBox.

Summary. Here we looked at how you can use ToolTips in your Windows Forms programs. Ideally, you can implement your tips entirely in the Designer, keeping all the code out of your private implementation.

Introduction

The following example demonstrate how to make a baloon tooltip hint message using «ToolTip» component.

About Windows ToolTip component

The Windows Forms ToolTip component displays text when the user mouse over a control on the form. You can associate the ToolTip control with any other control. You have to place the ToolTip control on your form for setting the properties such as Delay, Animation, Fading etc. Tooltip will help you to save the space in form to show messages as well as a small description of the particular control or item you want to show details.

A ToolTip component provides a ToolTip property to multiple controls on a Windows Form or other container. At the same time, you can inherit all the properties of the same control any of your form. That means you can dynamatically change the properties, tooltip style , color on your different forms or controls, based on your choice.

Methods of the ToolTip Component

There are two key methods are used in the ToolTip component. They are

SetToolTip, which you can use to get the ToolTips displayed for controls and

GetToolTip, can use to set the ToolTips displayed for controls.

Setting a tooltip

‘ In this example, Text1 is the control to display the ToolTip.
ToolTip1.SetToolTip(Text1, «To display employee name»)

Sample Program

A simple sample program attached herewith demonstrates to display baloon type popup tooltips over link labels such as Code project.com, Microsoft.com.

If any other issues, or comments, let me know.

thank you and have a wonderful day!
