Customize ColorPicker

Custom palette

By default, the Palette will be rendered with default colors. To load custom colors in the palette, specify the colors in the presetColors property. To customize the color palette, add a custom class to palette tiles using beforeTileRender event.

The following sample demonstrates the above functionalities.

tagHelper
custom-palette.cs
<div class='wrap'>
    <div id="preview"></div>
    <h4>Select Color</h4>
    <ejs-colorpicker id="element" mode="Palette" modeSwitcher="false" inline="true" showButtons="false" columns="4" presetColors="@ViewBag.customColors" beforeTileRender="tileRender" change="onChange"></ejs-colorpicker>
</div>

<style>
.e-container {
  background-color: transparent;
  border-color: transparent;
  box-shadow: none;
}
.e-container .e-palette .e-custom-tile {
  border: 0;
  color: #fff;
  height: 36px;
  font-size: 18px;
  width: 36px;
  line-height: 36px;
  border-radius: 50%;
  margin: 2px 5px;
}
.e-container .e-custom-palette.e-palette-group {
  height: 182px;
}
.e-container .e-palette .e-custom-tile.e-selected::before {

}
.wrap {
  margin: 0 auto;
  width: 300px;
  text-align: center;
}
#preview {
  background-color: #ba68c8;
  height: 50px;
  width: 100%;
}
</style>

<script>
    // Triggers while selecting colors from palette.
    function onChange(args) {
        document.getElementById('preview').style.backgroundColor = args.currentValue.hex;
    }
    // Triggers before rendering each palette tile.
    function tileRender(args) {
        args.element.classList.add("e-icons");
        args.element.classList.add("e-custom-tile");
    }
</script>
public IActionResult CustomPalette()
    {
            List<object> custom = new List<object>();
            custom.Add(new
            {
                Custom1 = new string[] {"#ef9a9a", "#e57373", "#ef5350",

            });

            ViewBag.customColors = custom[0];
            return View();
    }

Hide input area from picker

By default, the input area will be rendered in ColorPicker. To hide the input area from it, add e-hide-value class to ColorPicker using the cssClass property.

In the following sample, the ColorPicker is rendered without input area.

tagHelper
hide-input.cs
<div class='wrap'>
    <h4>Choose Color</h4>
    <ejs-colorpicker id="element" cssClass="e-hide-value" modeSwitcher="false"></ejs-colorpicker>
</div>

<style>
    .wrap {
        margin: 0 auto;
        width: 300px;
        text-align: center;
    }
</style>
public IActionResult HideInput()
    {
            return View();
    }

Custom handle

Color picker handle shape and UI can be customized. Here, we have customized the handle as svg icon. The same way you can customize the handle based on your requirement.

The following sample show the customized color picker handle.

tagHelper
custom-handle.cs
<div class='wrap'>
    <h4>Choose color</h4>
    <ejs-colorpicker id="element" cssClass="e-custom-picker" value="#344aae" modeSwitcher="false" open="onOpen"></ejs-colorpicker>
</div>

<script>
    // Triggers after the color picker popup open.
    function onOpen(args) {
      args.element.querySelector('.e-handler').classList.add('e-icons');
    }
</script>

<style>
  .wrap {
    margin: 0 auto;
    width: 300px;
    text-align: center;
  }

  /* To hide the handle balloon preview */
  .e-color-picker-tooltip.e-popup.e-popup-open {
    display: none;
  }

  /* Handle customization styles */
  .e-custom-picker .e-container .e-hsv-container .e-handler {

public IActionResult CustomHandle()
    {
        return View();
    }

Custom primary button

By default, the applied color will be updated in primary button of the color picker. You can customize that as icon.

In the following sample, the picker icon is added to primary button and using change event the selected color will be updated in bottom portion of the icon.

tagHelper
icon.cs
<div class='wrap'>
    <h4>Chosse color</h4>
    <ejs-colorpicker id="element" cssClass="e-custom-icon" change="onChange"></ejs-colorpicker>
</div>

<script>
    var iconPreview;
    window.onload = function () {
        iconPreview = document.querySelector('.e-custom-icon .e-selected-color');
        iconPreview.classList.add("e-icons");
    }
    function onChange(args) {
        iconPreview.style.borderBottomColor = args.currentValue.rgba;
    }
</script>

<style>
    .wrap {
        margin: 0 auto;
        width: 300px;
        text-align: center;
    }

    /* Icon customization */
    .e-custom-icon.e-colorpicker-wrapper .e-split-btn-wrapper .e-split-btn .e-selected-color {
        background: none;
        border-bottom-style: solid;
        border-bottom-width: 3px;
        width: 14px;
        margin: 0px 2px;
        border-bottom-color: #008000;
    }

    .e-custom-icon.e-colorpicker-wrapper .e-split-btn-wrapper .e-split-btn .e-selected-color .e-split-preview {
        display: none;
    }

    .e-custom-icon.e-colorpicker-wrapper .e-split-btn-wrapper .e-split-btn .e-selected-color::before {
        content: '\e35c';
    }
</style>
public IActionResult Icon()
    {
        return View();
    }

The Essential JS 2 provides a set of icons that can be loaded by applying e-icons class name to the element. You can also use third party icon to customize the primary button.

Display hex code in input

The color picker input element can be showcased in the place of primary button. The applied color hex code will be updated in the primary button input.

The following sample shows the color picker with input.

tagHelper
input.cs
<div class='wrap'>
    <h4>Choose color</h4>
    <ejs-colorpicker id="element" cssClass="e-custom-input"></ejs-colorpicker>
</div>

<script>
    window.onload = function () {
        var target = document.getElementById("element");
        ej.base.attributes(target, { "type": "text" });
        ej.base.addClass([target], "e-input");
        // Moving the ColorPicker input element before the secondary button.
        target.nextElementSibling.insertBefore(target, target.nextElementSibling.children[1]);
    }
</script>

<style>
    .wrap {
        margin: 0 auto;
        width: 300px;
        text-align: center;
    }

    /* Input element customization */

        position: initial;
        width: 75px;
    }

    /* To hide primary button */
    .e-custom-input.e-colorpicker-wrapper .e-split-btn-wrapper .e-split-btn {

        background: transparent;
        border-color: transparent;
        border-bottom-color: rgba(0, 0, 0, 0.42);
    }

    .e-custom-input.e-colorpicker-wrapper .e-split-btn-wrapper .e-input:focus+.e-btn.e-dropdown-btn {
        padding-bottom: 3px;
        border-bottom-width: 2px;
        border-bottom-color: #e3165b;
    }

    /* Rotating the dropdown arrow */
    .e-custom-input.e-colorpicker-wrapper .e-split-btn-wrapper .e-btn.e-dropdown-btn .e-caret {
        transform: rotate(0deg);
        transition: transform 200ms ease-in-out;
    }

    .e-custom-input.e-colorpicker-wrapper .e-split-btn-wrapper .e-btn.e-dropdown-btn.e-active .e-caret {

    }

public IActionResult Input()
    {
        return View();
    }
