# WPF ComboBox

[ComboBox](https://www.mindstick.com/articles/57/display-record-according-to-combobox-selection-in-csharp-dot-net) element represents a ComboBox [control](https://www.mindstick.com/blog/197/asp-dot-net-repeater-control) in XAML. \

<ComboBox></ComboBox>

**1.** Width and Height [properties](https://www.mindstick.com/articles/23331/nootropics-7-different-types-and-their-unique-properties) represent [width and height](https://www.mindstick.com/forum/158680/what-css-property-is-used-to-set-the-width-and-height-of-an-element) of a ComboBox.

**2.** X:Name [property](https://www.mindstick.com/blog/205/property-notification-in-c-sharp) represents the name of the control.

**3.** Margin property sets the [location](https://www.mindstick.com/blog/11636/relocating-business-or-office-to-another-location) of a ComboBox on the parent control (Location on Form or any other parent control).

**4.** **HorizontalAlignment** and **VerticalAlignment** properties are used to set horizontal and [vertical](https://www.mindstick.com/forum/12951/how-to-fix-bootstrap-tab-vertical-with-text) alignments.

**5.** The **IsSelected** property of the ComboBox control sets an item as currently selected item in the ComboBox.

```
<ComboBox Name="ComboBox1" Width="250" Height="35"          VerticalAlignment="Top" HorizontalAlignment="Right"             Margin="8,14,0,0">            </ComboBox>
```

The following line of code sets the IsSelected property of a ComboBox. \
