Getting Started

This tutorial will walk your through the creation of a sample application that contains RadCalculator and will show you how to:

• Use RadCalculator in your project

• Perform basic calculations

• Perform more complicated calculations

For the purpose of this example, you will need to create an empty SilverlightApplication project and open it in Visual Studio.

• Assembly References
• Adding RadCalculator to the Project
• Performing basic calculations with RadCalculator
• Performing complex calculations with RadCalculator

Assembly References

In order to use RadCalculator in your projects, you have to add reference to the following assemblies:

• Telerik.Windows.Controls
• Telerik.Windows.Controls.Input

Adding RadCalculator to the Project

Example 1: Defining RadCalculator

<UserControl x:Class="RadCalculator.MainPage" 
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" 
             xmlns:my="clr-namespace:RadCalculator" 
             mc:Ignorable="d" d:DesignHeight="700" d:DesignWidth="700">    
 
    <Grid x:Name="LayoutRoot" Background="White" > 
        <telerik:RadCalculator />        
    </Grid> 
</UserControl> 

Now if you run the application, you will have a RadCalculator:

Performing Basic Calculations with RadCalculator

RadCalculator allows you to perform all the basic calculations - addition, subtraction, multiplication, division. All of them can be executed either by the corresponding buttons or through the keyboard. Once a particular operation is executed, the history is updated accordingly:

Performing Complex Calculations with RadCalculator

RadCalculator allows you to perform a couple of more complex calculations - square root, reciprocal, percent, negate. All of them can be executed either by the corresponding buttons or through the keyboard. Once a particular operation is executed, the history is updated accordingly:
