Creating Drop Down

You can create a DropDown in XAML, through the designer or code.

In XAML

To create a C1DropDown control using XAML markup, complete the following steps:

1. In the Visual Studio Solution Explorer, right-click the References folder in the project files list. In the context menu choose Add Reference, select the C1.WPF.Input.dll assembly, and click OK.
2. Add a XAML namespace to your project by adding xmlns:c1="http://schemas.componentone.com/wpf/Basic" to the initial <Window> tag. It will appear similar to the following:

<Window x:Class="C1WPFPropertyGridCS102809.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="288" Width="418" xmlns:c1="http://schemas.componentone.com/wpf/Basic">

3. Add a <c1:C1DropDown> tag to your project within the <Grid> tag to create a C1DropDown control. The markup will appear similar to the following:

<Grid>
    <c1:C1DropDown Height="30" Name="C1DropDown1" Width="100"/>
</Grid>

This markup will create an empty C1DropDown control named "C1DropDown1" and set the control's size.

In Code

1. In the Visual Studio Solution Explorer, right-click the References folder in the project files list. In the context menu choose Add Reference, select the C1.WPF.Input.dll assembly, and click OK.

2. In XAML view, give the initial grid in the window a name, by updating the tag so it appears similar to the following:

   <Grid x:Name="LayoutRoot">
   

3. Right-click within the Window1.xaml window and select View Code to switch to Code view

4. Add the following import statements to the top of the page:

   Imports C1.WPF
   

   
   

   using C1.WPF;
   

5. Add code to the page's constructor to create the C1DropDown control. It will look similar to the following:

   Public Sub New()
       InitializeComponent()
       Dim c1DropDown1 as New C1DropDown
       c1DropDown1.Height = 30
       c1DropDown1.Width = 100
       LayoutRoot.Children.Add(c1DropDown1)
   End Sub
   

   
   

   public Window1()
   {
       InitializeComponent();
       C1DropDown c1DropDown1 = new C1DropDown();
       c1DropDown1.Height = 30;
       c1DropDown1.Width = 100;
       LayoutRoot.Children.Add(c1DropDown1);
   }
   

This code will create an empty C1DropDown control named "c1DropDown1", set the control's size, and add the control to the window.

In the Designer

1. Click once on the design area of the window to select it.
2. Double-click the C1DropDown icon in the Toolbox to add the control to the panel. The C1DropDown control will now exist in your application.
3. If you choose, you can customize the control by selecting it and setting properties in the Properties window.
