# Mutually Exclusive Checkable Items

## Content



You can create a group of mutually exclusive checkable items by setting the [GroupName](/componentone/api/wpf/online-menu5/dotnet-api/C1.WPF.Menu/C1.WPF.Menu.C1RadialMenuItem.GroupName.html) property of each item you wish to add to the group. For example, the XAML below will create a group of four mutually exclusive checkable items.

```xml
<c1:C1RadialMenu SectorCount="8" >
  <c1:C1RadialMenuItem Header="Insert" SectorCount="8" AutoSelect="True" ShowSelectedItem="True" IsCheckable="True" >
  <c1:C1RadialMenuItem Header="Insert Left" IsCheckable="True" GroupName="MutuallyExclusiveGroup"/>
  <c1:C1RadialMenuItem Header="Insert Above" DisplayIndex="2" IsCheckable="True" GroupName="MutuallyExclusiveGroup"/>
  <c1:C1RadialMenuItem Header="Insert Right" DisplayIndex="4" IsCheckable="True" GroupName="MutuallyExclusiveGroup"/>
  <c1:C1RadialMenuItem Header="Insert Below" DisplayIndex="6" IsCheckable="True" GroupName="MutuallyExclusiveGroup" />
  </c1:C1RadialMenuItem>
</c1:C1RadialMenu>
```

To create a group of **C1RadialMenuItems** and only allow one item to be checked at a time, follow these steps:

### In XAML

1.  Add **IsCheckable="True"** and **GroupName="CheckableGroup"** to the **<c1:C1RadialMenuItem>** tag of each **C1RadialMenuItem** you wish to add to the group of mutually exclusive checkable items.
2.  Run the program and click the first item in the group. Observe that the **C1RadialMenuItem** is highlighted.
3.  Now click the second item in the group and observe that the highlight is removed from the first item and then added to the second item.

### In Code

1.  Set the Name property of each **C1RadialMenuItem** you wish to add to the group of mutually exclusive checkable items.
2.  Open the MainPage.xaml.cs page.
3.  Set the **IsCheckable** and **GroupName** property of each **C1RadialMenuItem**, replacing **“ItemName”** with the value of the **C1RadialMenuItem**’s **Name** property.

```csharp
ItemName.IsCheckable = true;
```

4.  Run the program and tap the first item in the group and observe the following:

*   Observe that a check that resembles a thinner highlight is added to the **C1RadialMenuItem**.
*   Now tap the second item in the group and observe that the check is removed from the first item and then added to the second item.
