How to increase the Values of 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 which increases or decrease the Value property to Maximum and Minimum values when the up and down button clicked in the up-down control using the Increment Property. You can set this property in two different ways:
1. Design-Time: It is the easiest way to set the increment value in 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 increment of 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 increment value of the NumericUpDown control programmatically with the help of given syntax:
public decimal Increment { get; set; }
Here, the value of this property represents the increment or decrement of the Value property when the up and down button of the NumericUpDown control clicked. The default value of this property is 1. The following steps show how to set the increment 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 Increment property of the NumericUpDown provided by the NumericUpDown class.
// Setting the increment n.Increment = 1;
- 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);

NumericUpDown n =

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);
}
}
}
