The FlatColorPicker is part of Telerik UI for ASP.NET Core, a professional grade UI library with 110+ components for building modern and feature-rich applications. To try it out sign up for a free 30-day trial.

The Telerik UI FlatColorPicker TagHelper and HtmlHelper for ASP.NET Core are server-side wrappers for the Kendo UI FlatColorPicker widget.

The FlatColorPicker is the HSV color selector which is used by default in the kendo.ui.ColorPicker popup when no palette is set.

Initializing the FlatColorPicker

The following example demonstrates how to define the FlatColorPicker.

    @(Html.Kendo().FlatColorPicker()
          .Name("flatcolorpicker") // The name of the FlatColorPicker is mandatory. It specifies the "id" attribute of the widget.
          .Value("#ff0000") // Set the value of the FlatColorPicker.
    )

Events

You can subscribe to all FlatColorPicker events.

Handling by Handler Name

The following example demonstrates how to subscribe to events by a handler name.

      @(Html.Kendo().FlatColorPicker()
            .Name("flatcolorpicker")
            .Events(e => e
                  .Change("flatcolorpicker_change")
            )
      )
      <script>
          function flatcolorpicker_change(e) {
              //Handle the change event.
          }
      </script>
@addTagHelper *, Kendo.Mvc
@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers

<script>
        function change(e) {
             console.log("Change in picker #" + this.element.attr("id") + " :: " + e.value);
        }
</script>

<kendo-flatcolorpicker name="flatColorPicker" value="#00f" on-change="change">
</kendo-flatcolorpicker>

Handling by Template Delegate

The following example demonstrates how to subscribe to events by a template delegate.

      @(Html.Kendo().FlatColorPicker()
            .Name("flatcolorpicker")
            .Events(e => e
                .Change(@<text>
                  function(e) {
                      // Handle the change event inline.
                  }
                  </text>)
            )
      )

Referencing Existing Instances

To reference an existing Telerik UI FlatColorPicker instance, use the jQuery.data() configuration option. Once a reference is established, use the FlatColorPicker client-side API to control its behavior.

  // Place the following after your Telerik UI FlatColorPicker for ASP.NET Core declaration.
  <script>
  $(function() {
      // The Name() of the FlatColorPicker is used to get its client-side instance.
      var flatcolorpicker = $("#flatcolorpicker").data("kendoFlatColorPicker");
  });
  </script>
