<summary>Represents a selection control with a drop-down list that can be shown or hidden by clicking the arrow on the control.</summary>
<remarks>
<format type="text/markdown"><. To see the parts and states that are specific to the <xref:System.Windows.Controls.ComboBox>, see [ComboBox Styles and Templates](/dotnet/framework/wpf/controls/combobox-styles-and-templates).
Dependency properties for this control might be set by the control's default style. If a property is set by a default style, the property might change from its default value when the control appears in the application. The default style is determined by which desktop theme is used when the application is running.

## Remarks
The <xref:System.Windows.Controls.ComboBox.IsEditable%2A> and <xref:System.Windows.Controls.ComboBox.IsReadOnly%2A> properties specify how the <xref:System.Windows.Controls.ComboBox> behaves when the user does one of the following:
- Enters a string to select an item in the <xref:System.Windows.Controls.ComboBox>.
- Enters a string that does not correspond to an item in the <xref:System.Windows.Controls.ComboBox>.
- Selects part of the string that is in the text box.
- Copies or pastes a value into the text box.
The following table describes the actions the user can and cannot take, depending on the values of <xref:System.Windows.Controls.ComboBox.IsEditable%2A> and <xref:System.Windows.Controls.ComboBox.IsReadOnly%2A>.
| <xref:System.Windows.Controls.ComboBox.IsEditable> value |<xref:System.Windows.Controls.ComboBox.IsReadOnly%2A> is `true`|<xref:System.Windows.Controls.ComboBox.IsReadOnly%2A> is `false`|
| - | - | - |
| `true` |- Cannot select an item in the <xref:System.Windows.Controls.ComboBox> by entering a string.<br />- Cannot enter a string that does not correspond to an item in the <xref:System.Windows.Controls.ComboBox>.<br />- Can select part of the string in the <xref:System.Windows.Controls.ComboBox> text box.<br />- Can copy the string in the <xref:System.Windows.Controls.ComboBox> text box, but cannot paste a string into the <xref:System.Windows.Controls.ComboBox> text box.|- Can select an item in the <xref:System.Windows.Controls.ComboBox> by entering a string.<br />- Can enter a string that does not correspond to an item in the <xref:System.Windows.Controls.ComboBox>.<br />- Can select part of the string in the <xref:System.Windows.Controls.ComboBox> text box.<br />- Can copy or paste the string in the <xref:System.Windows.Controls.ComboBox> text box.|
| `false` |- Can select an item in the <xref:System.Windows.Controls.ComboBox> by entering a string.<br />- Cannot enter a string that does not correspond to an item in the <xref:System.Windows.Controls.ComboBox>.<br />- Cannot select part of the string in the <xref:System.Windows.Controls.ComboBox>.<br />- Cannot copy or paste the string in the <xref:System.Windows.Controls.ComboBox>.|- Can select an item in the <xref:System.Windows.Controls.ComboBox> by entering a string.<br />- Cannot enter a string that does not correspond to an item in the <xref:System.Windows.Controls.ComboBox>.<br />- Cannot select part of the string in the <xref:System.Windows.Controls.ComboBox>.<br />- Cannot copy or paste the string in the <xref:System.Windows.Controls.ComboBox>.|
When <xref:System.Windows.Controls.ComboBox.IsEditable%2A> is equal to `false`, the <xref:System.Windows.Controls.ComboBox> uses a <xref:System.Windows.Controls.ContentPresenter> to display the currently selected item; when <xref:System.Windows.Controls.ComboBox.IsEditable%2A> is equal to `true`, a <xref:System.Windows.Controls.TextBox> is used for this purpose instead. Note that a <xref:System.Windows.Controls.TextBox> only displays plain text, and that a <xref:System.Windows.Controls.ComboBoxItem> may include non-plain text content, such as images.
<a name="dependencyPropertyInfo_IsEditable"></a>
## Dependency Property Information
| Item | Value |
|-----------------------------------|--------------------------------------------------------|
|Identifier field|<xref:System.Windows.Controls.ComboBox.IsEditableProperty>|
|Metadata properties set to `true`|None|
## Examples
The following examples create <xref:System.Windows.Controls.ComboBox> controls that contain images as items instead of text. If the <xref:System.Windows.Controls.ComboBox.IsEditable%2A> property is set to `true`, the <xref:System.Windows.Controls.TextBox> displays the value returned by the image's <xref:System.Object.ToString%2A> method. To avoid a <xref:System.Windows.Controls.TextBox> with unexpected text, use the <xref:System.Windows.Controls.TextSearch.Text%2A?displayProperty=nameWithType> and <xref:System.Windows.Controls.TextSearch.TextPath%2A?displayProperty=nameWithType> properties to assign text to be displayed.

:::code language="xaml" source="~/snippets/csharp/System.Windows.Controls/ComboBox/IsEditable/pane1.xaml" id="Snippet2":::
Another solution is to use the <xref:System.Windows.Controls.ItemsControl.DisplayMemberPath%2A> property. The drop-down control of the <xref:System.Windows.Controls.ComboBox> will not display the images but will display the text you assigned.
The following example shows how to use <xref:System.Windows.Controls.ItemsControl.DisplayMemberPath%2A>.

## Remarks
This property is a dependency property. However, the dependency property identifier field for <xref:System.Windows.Controls.ComboBox.IsSelectionBoxHighlighted%2A> is not public. Therefore, you cannot use the backing dependency property for property system operations that require the dependency property identifier, such as calls to <xref:System.Windows.DependencyObject.GetValue%2A>. However, you can still use <xref:System.Windows.Controls.ComboBox.IsSelectionBoxHighlighted%2A> as a property trigger.

<summary>Gets or sets the maximum height for a combo box drop-down.</summary>
<value>A double that represents the height that is retrieved or the height to set. The default value as defined to the property system is a calculated value based on taking a one-third fraction of the system max screen height parameters, but this default is potentially overridden by various control templates.</value>
<remarks>
<format type="text/markdown"><![CDATA[
## Remarks
Auto sizing is not the default, and will result in the drop down size potentially exceeding the available size in the parent element. This is not typically desirable.

## Dependency Property Information
| Item | Value |
|-----------------------------------|--------------------------------------------------------|
|Identifier field|<xref:System.Windows.Controls.ComboBox.MaxDropDownHeightProperty>|
|Metadata properties set to `true`|None|
<a name="xamlAttributeUsage_MaxDropDownHeight"></a>
## XAML Attribute Usage
```
<object MaxDropDownHeight="double"/>
- or -
<object MaxDropDownHeight ="qualifiedDouble"/>
- or -
<object MaxDropDownHeight ="Auto"/>
```
<a name="xamlValues_MaxDropDownHeight"></a>
## XAML Values
*double*
<xref:System.Double>
String representation of a <xref:System.Double> value. This is interpreted as a device-independent unit (1/96th inch) measurement. Strings need not explicitly include decimal points. For instance a value of `1` is acceptable.
The same <xref:System.Double> range restrictions as mentioned in the Property Value section apply.
*qualifiedDouble*
A *double* value as described above, followed by one of the following unit declaration strings: `px`, `in`, `cm`, `pt`.
`px` (default) is device-independent units (1/96th inch per unit)
`in` is inches; 1in==96px
`cm` is centimeters; 1cm==(96/2.54) px
`pt` is points; 1pt==(96/72) px
`Auto`
Enables autosizing behavior. See Remarks.
## Examples
The following example shows how to use the <xref:System.Windows.Controls.ComboBox.MaxDropDownHeight%2A> property to specify the height of the <xref:System.Windows.Controls.ComboBox> control's drop-down.
