Setting Values

There are four properties to set to control the currently selected number (Value), how much that number changes when the Up or Down button is clicked at run-time (Increment), and the range of numbers that can be selected (Minimum and Maximum).

Start Value

The Value property determines the currently selected number. By default the C1NumericBox control starts with its Value set to 0 but you can customize this number at design time, in XAML, and in code.


In XAML


To set the Value property add Value="123" to the <c1:C1NumericBox> tag so that it appears similar to the following:

<c1:C1NumericBox Name="C1NumericBox1" Value="123" />

In Code


To set the Value property add the following code to your project:

C1NumericBox1.Value = 123
c1NumericBox1.Value = 123;

At Design Time


To set the Value property at run time, complete the following steps:

  1. Click the C1NumericBox control once to select it.

  2. Navigate to the Properties window, and enter a number, for example "123", in the text box next to the Value property.

This will set the Value property to the number you chose.

Increment Value

The Increment property determines by how much the Value property changes when the Up or Down button is clicked at run time. By default the C1NumericBox control starts with its Increment set to 1 but you can customize this number at design time, in XAML, and in code.


In XAML


To set the Increment property to 20 add Increment="20" to the <c1:C1NumericBox> tag so that it appears similar to the following:

<c1:C1NumericBox Name="C1NumericBox1" Increment="20" />

In Code


To set the Increment property to 20 add the following code to your project:

C1NumericBox1.Increment = 20
c1NumericBox1.Increment = 20;

At Design Time


To set the Increment property at run time, complete the following steps:

  1. Click the C1NumericBox control once to select it.

  2. Navigate to the Properties window, and enter a number, for example "20", in the text box next to the Increment property.

This will set the Increment property to the number you chose.

Minimum and Maximum Values

You can use the Minimum and Maximum properties to set a numeric range that users are limited to at run time. If the Minimum and Maximum properties are set, users will not be able to pick a number smaller than the Minimum or larger than the Maximum.


In XAML


To set the Minimum and Maximum in XAML add Maximum="500" Minimum="-500" to the <c1:C1NumericBox> tag so that it appears similar to the following:

<c1:C1NumericBox Name="C1NumericBox1" Maximum="500" Minimum="-500" />

In Code


To set the Minimum and Maximum add the following code to your project:

C1NumericBox1.Minimum = -500
C1NumericBox1.Maximum = 500
c1NumericBox1.Minimum = -500;
c1NumericBox1.Maximum = 500;

At Design Time


To set the Minimum and Maximum at run time, complete the following steps:

  1. Click the C1NumericBox control once to select it.

  2. Navigate to the Properties window, and enter a number, for example 500, next to the Maximum property.

  3. In the Properties window, enter a number, for example -500, next to the Minimum property.

This will set Minimum and Maximum values.
