# Adding Groups to the C1TileControl

## Content



Groups can be created at design time or programmatically. At design time they can be created using the **C1TileControl.Groups Collection Editor**. Groups can also be created programmatically through the [Group](/componentone/docs/win/online-tilecontrol/) class. The group can be inserted into the GroupCollection at the specified index using the [InsertItem](/componentone/docs/win/online-tilecontrol/) method.

### Design-Time

To add a template at design time, complete the following:

1.  Right-click the **C1TileControl** and select **Edit Groups** to open the **C1TileControl.Groups Collection Editor**.
2.  Click the **Add** button to add a new group to the C1TileControl. The Groups text will appear empty and there will be no tiles until you add the tiles to the group.
