Tooltip Positioning in Tooltip Control

21 Dec 202215 minutes to read

Tooltips can be attached to 12 static locations around the target. On initializing the Tooltip, you can set the position property with any one of the following values:

  • TopLeft
  • TopCenter
  • TopRight
  • BottomLeft
  • BottomCenter
  • BottomRight
  • LeftTop
  • LeftCenter
  • LeftBottom
  • RightTop
  • RightCenter
  • RightBottom

NOTE

By default, Tooltip is placed at the TopCenter of the target element.

Tip pointer positioning

The Tooltip pointer can be attached or detached from the Tooltip by using the showTipPointer property. Pointer positions can be adjusted using the tipPointerPosition property that can be assigned to one of the following values:

  • auto
  • start
  • middle
  • end

The following code example illustrates how to set the pointer to the start position of the Tooltip.

@using Syncfusion.EJ2
@using Syncfusion.EJ2.Popups
     @Html.EJS().Tooltip("Tooltip").Content("Tooltip content").TipPointerPosition(Syncfusion.EJ2.Popups.TipPointerPosition.Start).ContentTemplate(@<div>
        <div id='target'>
            <span>Show Tooltip</span>
        </div>
    </div>).Render()


<style>
    #container {
        visibility: hidden;
    }

    #loader {
        color: #008cff;
        height: 40px;
        left: 45%;
        position: absolute;
        top: 45%;
        width: 30%;
    }

    #target {
        background-color: #ececec;
        border: 1px solid #c8c8c8;
        box-sizing: border-box;
        margin: 50px auto;
        padding: 20px;
        width: 250px;
    }
</style>
public ActionResult TipPointer()
{
    ViewBag.content = "Tooltip Content";
    return View();
}

Output be like the below.

ASP .NET Core - Tooltip - Tip Pointer Position

By default, tip pointers are auto adjusted so that the arrow does not point outside the target element.

Dynamic positioning

The Tooltip and its tip pointer can be positioned dynamically based on the target’s location. This can be achieved by using the refresh method, which auto adjusts the Tooltip over the target.

@using Syncfusion.EJ2
@using Syncfusion.EJ2.Popups

<div class="control-section">
        <!-- Tooltip element -->
        @Html.EJS().Tooltip("targetContainer").Content("Drag me").Target("#demoSmart").ContentTemplate(@<div id="demoSmart">
        </div>).Render()
    </div>


<script type="text/javascript">
    var tooltip, ele;
    window.onload = function () {
        ele = document.getElementById('demoSmart');
        tooltip = document.getElementById("targetContainer").ej2_instances[0];
        ////Initialize Draggable for tooltip element
        var drag = new ej.base.Draggable(ele, {
            clone: false,
            dragArea: '#targetContainer',
            drag: function (args) {
                if (args.element.getAttribute('data-tooltip-id') === null) {
                    tooltip.open(args.element);
                }
                else {
                    tooltip.refresh(args.element);
                }
            },
            dragStart: function (args) {
                if (args.element.getAttribute('data-tooltip-id') !== null) {
                    return;
                }
                tooltip.open(args.element);
            },
            dragStop: function (args) {
                tooltip.close();
            }
        });
    }
</script>

<style type="text/css">
    #demoSmart {
        background: rebeccapurple;
        height: 50px;
        left: 35%;
        position: absolute;
        top: 35%;
        width: 50px;
    }
      #targetContainer {
        margin: 10px;
        min-height: 320px;
        width: 100%;
        float: left;
        border: 1px solid #dddddd;
        border-radius: 3px;
    }

    .control-section {
        padding: 3px;
        margin-right: 20px;
    }
 </style>
public ActionResult DynamicPosition()
{
    ViewBag.custom = "Drag Me";
    return View();
}

NOTE

When mouse trailing option is enabled, the tip pointer position gets auto adjusted based on the target, and other position values like start, end, and middle are not applied (to prevent the pointer from moving out of target).

Output be like the below.

Mouse Trailing

Tooltips can be positioned relative to the mouse pointer. This behavior can be enabled or disabled by using the mouseTrail property. By default, it is set to false.

@using Syncfusion.EJ2
@using Syncfusion.EJ2.Popups
    @Html.EJS().Tooltip("Tooltip").MouseTrail(true).Content("Tooltip content").ContentTemplate(@<div>
        <div id="target" style="margin: 50px;">
                Show tooltip
        </div>
    </div>).Render()


<style>
    #target {
        background-color: #ececec;
        border: 1px solid #c8c8c8;
        box-sizing: border-box;
        margin: 80px auto;
        padding: 20px;
        width: 200px;
    }
</style>
public ActionResult MouseTrailing()
{
    return View();
}

Output be like the below.

ASP .NET Core - Tooltip - Mouse Trail

NOTE

When mouse trailing option is enabled, the tip pointer position gets auto adjusted based on the target, and other position values like start, end, and middle are not applied (to prevent the pointer from moving out of target).

Setting offset values

Offset values are set to specify the distance between the target and tooltip element.
offsetX and offsetY properties are used to specify the offset left and top values.

  • offsetX specifies the distance between the target and Tooltip element in X axis.
  • offsetY specifies the distance between the target and Tooltip element in Y axis.

The following code example illustrates how to set offset values.

@using Syncfusion.EJ2
@using Syncfusion.EJ2.Popups
  @Html.EJS().Tooltip("tooltip").OffsetX(30).OffsetY(30).MouseTrail(true).ShowTipPointer(false).Content("Tooltip content").ContentTemplate(@<div>
        <div id="target">Show tooltip</div>
    </div>).Render()

<style>
    #target {
        background-color: #ececec;
        border: 1px solid #c8c8c8;
        box-sizing: border-box;
        margin: 80px auto;
        padding: 20px;
        width: 200px;
    }
</style>
public ActionResult offsetvalues()
{
    ViewBag.content = "Tooltip Content";
    return View();
}

Output be like the below.

NOTE

By default, collision is handled automatically and therefore when collision is detected the Tooltip fits horizontally and flips vertically.
