# Important Settings

**RadToolTip** and **RadToolTipManager** include several properties to control tooltip behavior:

* Use properties [Position, RelativeTo, OffsetX, OffsetY](https://www.telerik.com/products/aspnet-ajax/documentation/controls/tooltip/getting-started/positioning) to precisely position the tooltip.

* Use the **ContentScrolling** property to customize the availability of scrollbars. Possible values are Auto, None X, Y and Both.

* **HideEvent = "ManualClose"** displays a close button graphic in the tooltip. The tooltip stays open until the user clicks the button.

* The **Modal** property when **True** grays everything in the background of the tooltip.

* The **MouseTrailing** property when **True** causes the tooltip to follow the mouse. When **False** the tooltip stays in the initial position dictated by the [RelativeTo](https://www.telerik.com/products/aspnet-ajax/documentation/controls/tooltip/getting-started/positioning) property.

* The **ShowCallout** property when True (the default) displays the [callout](https://www.telerik.com/products/aspnet-ajax/documentation/controls/tooltip/getting-started/radtooltip-structure) graphic on the tooltip.

* Use [ShowDelay and AutoCloseDelay](https://www.telerik.com/products/aspnet-ajax/documentation/controls/tooltip/getting-started/showdelay-and-autoclosedelay) to control the timing of tooltip opening and closing.

* Use the [ShowEvent](https://www.telerik.com/products/aspnet-ajax/documentation/controls/tooltip/getting-started/showevent) property to control how a tooltip is triggered.

* Use [Sticky](https://www.telerik.com/products/aspnet-ajax/documentation/controls/tooltip/getting-started/sticky-tooltips) tooltips to prevent tooltips from hiding when the mouse moves away.

* The [Text](https://www.telerik.com/products/aspnet-ajax/documentation/controls/tooltip/getting-started/radtooltip-structure) property can be used to [populate the content](https://www.telerik.com/products/aspnet-ajax/documentation/controls/tooltip/radtooltip/managing-content) of the tooltip.

* The [Title](https://www.telerik.com/products/aspnet-ajax/documentation/controls/tooltip/radtooltip/managing-content) property can contain text displayed at the top of the tooltip.

In addition, **RadToolTip** uses the [TargetControlID](https://www.telerik.com/products/aspnet-ajax/documentation/controls/tooltip/radtooltip/using-the-targetcontrolid-property) property to identify the target element for the tooltip. **RadToolTipManager** uses the [TargetControls](https://www.telerik.com/products/aspnet-ajax/documentation/controls/tooltip/radtooltipmanager/using-the-targetcontrols-collection) collection to identify multiple target elements to "tooltipify".

You can find online demos which set server properties in the **Server-side properties** section of RadToolTip's demos.
