How to: Set and Return Numeric Values with the Windows Forms NumericUpDown Control

Article

The numeric value of the Windows Forms NumericUpDown control is determined by its Value property. You can write conditional tests for the control's value just as with any other property. Once the Value property is set, you can adjust it directly by writing code to perform operations on it, or you can call the UpButton and DownButton methods.

To set the numeric value

Assign a value to the Value property in code or in the Properties window.

NumericUpDown1.Value = 55

numericUpDown1.Value = 55;

numericUpDown1.set_Value(new Decimal(55));

numericUpDown1->Value = 55;

-or-

Call the UpButton or DownButton method to increase or decrease the value by the amount specified in the Increment property.
```
NumericUpDown1.UpButton()
```
```
numericUpDown1.UpButton();
```
```
numericUpDown1.UpButton();
```
```
numericUpDown1->UpButton();
```

To return the numeric value

Access the Value property in code.

If NumericUpDown1.Value >= 65 Then
   MessageBox.Show("Age is: " & NumericUpDown1.Value.ToString)
Else
   MessageBox.Show("The customer is ineligible for a senior citizen discount.")
End If

if(numericUpDown1.Value >= 65)
{
   MessageBox.Show("Age is: " + numericUpDown1.Value.ToString());
}
else
{
   MessageBox.Show("The customer is ineligible for a senior citizen discount.");
}

if (Decimal.Compare(numericUpDown1.get_Value(), new Decimal(65)) >= 0)
{
   MessageBox.Show(("Age is: " + numericUpDown1.get_Value().ToString()));
}
else
{
   MessageBox.Show("The customer is ineligible for a senior citizen discount.");
}

if(numericUpDown1->Value >= 65)
{
   MessageBox::Show(String::Concat("Age is: ",
      numericUpDown1->Value.ToString()));
}
else
{
   MessageBox::Show
      ("The customer is ineligible for a senior citizen discount.");
}
