In Windows Forms, the DateTimePicker control is used to select and display date/time with a specific format in your form. In DateTimePicker control, you are allowed to set a spin button control or up-down control in the DateTimePicker to adjust date/time using the ShowUpDown Property. If the value of this property is set to true, then an up-down control display in the DateTimePicker control, otherwise, false. You can set this property in two different ways:
1. Design-Time: It is the easiest way to set an up-down control in the DateTimePicker as shown in the following steps:
- Step 1: Create a windows form as shown in the below image:
Visual Studio -> File -> New -> Project -> WindowsFormApp
- Step 2: Next, drag and drop the DateTimePicker control from the toolbox to the form as shown in the below image:
- Step 3: After drag and drop you will go to the properties of the DateTimePicker and set an up-down control in the DateTimePicker as shown in the below image:
Output:
2. Run-Time: It is a little bit trickier than the above method. In this method, you can set an up-down control in the DateTimePicker control programmatically with the help of given syntax:
public bool ShowUpDown { get; set; }
The value of this property is of System.Boolean type, either true or false. The default value of this property is false. The following steps show how to set an up-down control in the DateTimePicker dynamically:
- Step 1: Create a DateTimePicker using the DateTimePicker() constructor is provided by the DateTimePicker class.
// Creating a DateTimePicker DateTimePicker dt = new DateTimePicker();
- Step 2: After creating DateTimePicker, set the ShowUpDown property of the DateTimePicker provided by the DateTimePicker class.
// Setting the ShowUpDown property dt.ShowUpDown = true;
- Step 3: And last add this DateTimePicker control to the form using the following statement:
// Adding this control to the form this.Controls.Add(dt);
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 WindowsFormsApp49 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Load( object sender, EventArgs e) { // Creating and setting the // properties of the Label Label lab = new Label(); lab.Location = new Point(183, 162); lab.Size = new Size(172, 20); lab.Text = "Select Time" ; lab.Font = new Font( "Comic Sans MS" , 12); // Adding this control to the form this .Controls.Add(lab); // Creating and setting the // properties of the DateTimePicker DateTimePicker dt = new DateTimePicker(); dt.Location = new Point(360, 162); dt.Size = new Size(292, 26); dt.MaxDate = new DateTime(2500, 12, 20); dt.MinDate = new DateTime(1753, 1, 1); dt.Format = DateTimePickerFormat.Time; dt.Name = "MyPicker" ; dt.Font = new Font( "Comic Sans MS" , 12); dt.ShowUpDown = true ; // Adding this control // to the form this .Controls.Add(dt); } } } |
