Setting Dimension

Height and width

The Tooltip can either be assigned auto height and width values or specific pixel values. The width and height properties are used to set the outer dimension of the Tooltip element. The default value for both the properties is auto. It also accepts string and number values in pixels.

The following sample explains how to set dimensions for the Tooltip.

height-width.cs
@section ControlsSection{
    <ejs-tooltip id="tooltip" height="40px" width="150px" content="Tooltip with specific width and height">
        <e-content-template>
                <span id='target'>Show Tooltip</span>
        </e-content-template>
    </ejs-tooltip>
}
<style>
    #tooltip {
        position: absolute;
        left: calc( 50% - 60px);
        top: 38%;
    }
</style>
public ActionResult Dimension()
