Animation

To animate the Tooltip, a set of specific animation effects are available, and it can be controlled using the animation property. The animation property also allows you to set delay, duration, and various other effects of your choice.

AnimationModel is derived from base to apply the chosen animation effect, duration, etc. on Tooltips.

By default, Tooltip entrance occurs over 150 ms using the ease-out timing function. It exits also at 150 ms, but uses ease-in timing function.

@using Syncfusion.EJ2
@using Syncfusion.EJ2.Popups
@section ControlsSection{
    @Html.EJS().Tooltip("tooltip").Content("Tooltip content").Animation(new {
    open = new { effect = "ZoomIn", duration = 1000, delay = 0 },
    close = new { effect = "ZoomOut", duration = 500, delay = 0 }
}).ContentTemplate(@<div id="target">
        Show tooltip
    </div>).Render() 
}

    #target {
        background-color: #ececec;
        border: 1px solid #c8c8c8;

        margin: 50px auto;
        padding: 10px;
        width: 100px;
    }

ASP .NET Core - Tooltip - Animation

The default animation effect for the Tooltip is set to FadeIn for its open action, and FadeOut for its close action. The default duration is set to 150 ms and delay is set to 0.

Animation effects

The animation effects that are applicable to Tooltips are:

  • FadeIn
  • FadeOut
  • FadeZoomIn
  • FadeZoomOut
  • FlipXDownIn
  • FlipXDownOut
  • FlipXUpIn
  • FlipXUpOut
  • FlipYLeftIn
  • FlipYLeftOut
  • FlipYRightIn
  • FlipYRightOut
  • ZoomIn
  • ZoomOut
  • None

When the effect is specified as None, no effect will be applied to the Tooltip, and animation is considered to be set to off.

Some of the above animation effects suits the Tooltip better when its tip pointer is hidden. This can be achieved by setting the showTipPointer to false.

Animating via open/close methods

Animations can also be applied on Tooltips dynamically through open and close methods. These methods accept the animation model as an optional parameter. If you pass TooltipAnimationSettings, animation takes this model; otherwise, it takes the values from the animation property. It is also possible to pass different animations for Tooltips on each target.

Refer to the code snippet below to apply animations using public methods.

@using Syncfusion.EJ2

@section ControlsSection{
    @Html.EJS().Tooltip("tooltip").Content("Tooltip content").OpensOn("Custom").ContentTemplate(@<div id="target">

    }

    function created() {
    document.getElementById('target').addEventListener("click", function () {
            var tooltip = document.getElementById('tooltip').ej2_instances[0];
            if (this.getAttribute("data-tooltip-id")) {
                var closeAnimation = { effect: 'FadeOut', duration: 1000 }
                tooltip.close(closeAnimation);
            } else {
                var openAnimation = { effect: 'FadeIn', duration: 1000 }
                tooltip.open(this, openAnimation);
            }
        });
    }

Apply transition

The transition effect can be applied on Tooltips by using the beforeRender event as given in the following work-around code example.

@section ControlsSection{
    @Html.EJS().Tooltip("tooltip").Target(".circletool").BeforeRender("onBeforeRender").AfterClose("onAfterClose").CloseDelay(1000).Animation(new {
   open = new { effect = "ZoomIn", duration = 500 },
   close = new { effect = "ZoomOut", duration = 500 }
}).ContentTemplate(@<div>
        <h3> Transition effect </h3>
