Get started with MultiSelect, the WinForms control that provides the ease of selecting multiple objects from a list/collection. See more in documentation here.

## Content



MultiSelect provides [SelectionMode](/componentone/docs/win/online-multiselect/) property to determine whether you can select one or more than one item from the header. This property lets you choose between the following selection modes through **SelectionMode** enumeration:

*   **Single**: Allows you to select only one item at a time.
*   **Multiple**: Allows you to select multiple items without holding down a modifier key.
*   **Extended**: Allows you to select multiple consecutive items while holding down the corresponding modifier key.

To set the selection mode to multiple, use the following code:

**vbnet**

```vbnet
C1MultiSelect1.SelectionMode = C1.Win.TreeView.SelectionMode.Single
```

**csharp**

```csharp
c1MultiSelect1.SelectionMode = C1.Win.TreeView.SelectionMode.Single;
```
