By default, when the user clicks the C1ComboBoxcontrol's drop-down arrow at run-time, the drop-down list will appear below the control; if that is not possible, it will appear above the control. You can, however, change the direction in which the drop-down list appears by setting the DropDownDirection property to one of the following four options:
Event | Description |
BelowOrAbove (default) | Tries to open the drop-down list below the header. If it is not possible tries to open above it. |
AboveOrBelow | Tries to open the drop-down list above the header. If it is not possible tries to open below it. |
ForceBelow | Forces the drop-down list to open below the header. |
ForceAbove | Forces the drop-down list to open above the header. |
