How to set Minimum Value in NumericUpDown in C#?
In windows forms, NumericUpDown control is used to provide a Windows spin box or an up-down control which displays the numeric values. Or in other words, NumericUpDown control provides an interface which moves using up and down arrow and holds some pre-defined numeric value. In NumericUpDown control, you can set the minimum value for the up-down control using Maximum Property. The default value of this property is 0. You can set this property in two different ways:
1. Design-Time: It is the easiest way to set the minimum value for the NumericUpDown 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 NumericUpDown control from the toolbox on the form as shown
- Step 3: After drag and drop you will go to the properties of the NumericUpDown and set the minimum value for the NumericUpDown 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 the minimum value for the NumericUpDown control programmatically with the help of given syntax:
public decimal Minimum { get; set; }
Here, the value of this property represents the minimum value of the NumericUpDown. The following steps show how to set the minimum value for the NumericUpDown dynamically:
- Step 1: Create a NumericUpDown using the NumericUpDown() constructor is provided by the NumericUpDown class.
// Creating a NumericUpDown NumericUpDown n = new NumericUpDown();
- Step 2: After creating NumericUpDown, set the Minimum property of the NumericUpDown provided by the NumericUpDown class.
// Setting the minimum value n.Minimum = 18;
- Step 3: And last add this NumericUpDown control to the form using the following statement:
// Adding NumericUpDown control on the form this.Controls.Add(n);
- 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 WindowsFormsApp42 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Load( object sender, EventArgs e) { // Creating and setting the // properties of the labels Label l1 = new Label(); l1.Location = new Point(348, 61); l1.Size = new Size(215, 20); l1.Text = "Form" ; l1.Font = new Font( "Bodoni MT" , 12); this .Controls.Add(l1); Label l2 = new Label(); l2.Location = new Point(242, 136); l2.Size = new Size(103, 20); l2.Text = "Enter Age" ; l2.Font = new Font( "Bodoni MT" , 12); this .Controls.Add(l2); // Creating and setting the // properties of NumericUpDown NumericUpDown n = new NumericUpDown(); n.Location = new Point(386, 130); n.Size = new Size(126, 26); n.Font = new Font( "Bodoni MT" , 12); n.Value = 18; n.Minimum = 18; n.Maximum = 30; n.BackColor = Color.LightGreen; n.ForeColor = Color.DarkGreen; n.Increment = 1; n.Name = "MySpinBox" ; // Adding this control // to the form this .Controls.Add(n); } } } |
