The element represents a ComboBox in XAML. A ComboBox is a collection of ComboBoxItems represented by element in XAML. Here in this article I am going to show that how we can create ComboBox and how we can add item in the ComboBox.  By default, the ComboBox height and width is full screen. In a ComboBox we can use CheckBox item, Images etc.

The following window1.Xaml code is showing that how we can create the ComboBox and add item in that ComboBox.

<Window x:Class="XAMLComboBox.Window1"

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    Title="XAMLComboBox" Height="300" Width="300"

    >

  <!--Here in ComboBox we find a property IsEditable if we set it as True the we can write anything inside the ComboBox-->

  <!--By Default the height and width of ComboBox is same as OPage Size So here we can set the height and width Property -->

  <ComboBox IsEditable="False" Width="150" Height="150">

    <!--From here I am adding the Item in ComboBox-->

    <ComboBoxItem FontSize="15">India</ComboBoxItem>

    <ComboBoxItem >USA</ComboBoxItem>

    <ComboBoxItem FontSize="15">England</ComboBoxItem>

    <ComboBoxItem FontSize="15">Switzerland</ComboBoxItem>

    <ComboBoxItem FontSize="15"></ComboBoxItem>    

  </ComboBox>

</Window>

The window will become look like as:

We can also add images in a ComboBox. We can do it by using a ComboBox property. This window1.Xaml code is showing that how we can add images in a ComBox.

<Window x:Class="XAMLComboBox.Window1"

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    Title="XAMLComboBox" Height="300" Width="300"

    >

    <!--To add Images in ComboBox-->

    <!--Here in Image element we have to set height and Width property Otherwise Image will show in actual Size-->
    <ComboBox IsEditable="False" Width="150" Height="150">

    <Image Name="Image1" Source="1.jpg" Height="100" Width="100"/>

    <Image Name="Image2" Source="2.jpg" Height="100" Width="100"/>

    <Image Name="Image3" Source="3.jpg" Height="100" Width="100"/>

    <Image Name="Image4" Source="4.jpg" Height="100" Width="100"/>    

  </ComboBox>

</Window>

The window will become look like as:
