How to set Value in the 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 a value in the up-down control using the Value Property. This value is the current value of Up-Down control and the value is in between Minimum and Maximum values. You can set this property in two different ways:
1. Design-Time: It is the easiest way to set the value 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 in the below image:
- Step 3: After drag and drop you will go to the properties of the NumericUpDown and set the value 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 current value in the NumericUpDown control programmatically with the help of given syntax:
public decimal Value { get; set; }
It contains the numeric value of the NumericUpDown control. It will throw an ArgumentOutOfRangeException if the value assigns to this property is less than Minimum value or greater than Maximum value. The following steps show how to set value in 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 Value property of the NumericUpDown provided by the NumericUpDown class.
// Setting the value n.Value = 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);

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);
