# Step 1 of 4: Creating an Application

## Content



In this step, you'll create an application using **ComboBox for WPF and Silverlight**.

Complete the following steps:

1.  In Visual Studio, select **File | New Project**.
2.  In the **New Project dialog box**, select either **Windows Desktop** or **Silverlight** from the **Templates** in the left-hand pane.

3.  Select **WPF Application** or **Silverlight Application**, depending on the template you chose.
4.  Enter a **Name** for your project, for example "QuickStart", and click **OK**. In a **WPF Application**, the **MainWindow.xaml** file will open.
    1.  If you selected a **Silverlight Application**, when you click **OK**, the **New Silverlight Application** dialog box will appear.
    2.  Click **OK** to accept default settings. This will close the **New Silverlight Application** dialog box and create your project.
    3.  The **MainPage.xaml** file should open.
5.  Add the following assemblies to your application by right-clicking the **References** folder and selecting **Add Reference**:
    *   **WPF**: C1.WPF.4.dll
    *   **Silverlight**: C1.Silverlight.5.dll
6.  In the Visual Studio **Toolbox**, locate the **StackPanel** control and double-click to add it to your page. Edit the **StackPanel**'s properties to reflect the following:
    *   **Width = "300"**
    *   **Height = "35"**
    *   **Orientation = Horizontal**
7.  Locate the **ComboBox** control in the **Toolbox** and add two controls to the **StackPanel** by double-clicking the control. These two controls will be named, by default, **combobox1** and **combobox2**.
8.  Edit **combobox1**'s properties to reflect the following:
    *   **Width = "150"**
    *   **Height = "35"**
    *   **Name = "Category"**
9.  Edit **combobox2**'s properties to reflect the following:
    *   **Width = "150"**
    *   **Height = "35"**
    *   **Name = "Shows"**

You have completed the first step of the quick start by creating a WPF or Silverlight project and adding two **C1ComboBox** controls to it. In the next step, you'll add items to the first **C1ComboBox** control.
