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. In ToolTip, you are allowed to change the shape of the ToolTip window by using IsBalloon Property.
With the help of this property, you can change the ToolTip window from the standard rectangular window to the balloon window. You can set this property in two different ways:
1. Design-Time: It is the easiest way to set the value of the IsBalloon property as shown in the following steps:
2. Run-Time: It is a little bit trickier than the above method. In this method, you can set the IsBalloon property of ToolTip programmatically with the help of given syntax:
public bool IsBalloon { get; set; }
Here, the value of this property is of System.Boolean type. If the value of this property is set to true, then the ToolTip window is of balloon window. And if the value of this property is set to be false, then the ToolTip window is of the standard rectangular window. The default value of this property is false.
The following steps show how to set the IsBalloon Property of the ToolTip dynamically:
- Step 1: Create a ToolTip using the ToolTip() constructor is provided by the ToolTip class.
// Creating a ToolTip
ToolTip t = new ToolTip();
- Step 2: After creating Tooltip, set the IsBalloon property of the Tooltip provided by the ToolTip class.
// Setting the IsBalloon property
t.IsBalloon = true;
- Step 3: And last add this ToolTip to the controls using SetToolTip() method. This method contains the control name and the text which you want to display in the ToolTip box.
t.SetToolTip(box1, "Name should start with Capital letter");
Example:
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 = new ToolTip();
t.Active = true ;
t.AutoPopDelay = 4000;
t.InitialDelay = 600;
t.IsBalloon = true ;
t.SetToolTip(box1, "Name should start with Capital letter" );
t.SetToolTip(box2, "Password should be greater than 8 words" );
}
}
}
