The Telerik UI ColorPicker TagHelper and HtmlHelper for ASP.NET Core are server-side wrappers for the Kendo UI ColorPicker widget.
The ColorPicker is a drop-down list for selecting colors.
Initializing the ColorPicker
The following example demonstrates how to define the ColorPicker.
@(Html.Kendo().ColorPicker()
.Name("colorpicker") // The name of the ColorPicker is mandatory. It specifies the "id" attribute of the widget.
.Value("#ff0000") // Set the value of the ColorPicker.
)
<kendo-colorpicker name="colorpicker" value="#ff0000">
<messages apply="Change" cancel="Close" />
</kendo-colorpicker>
Starting with the 2024 Q3 release, the HtmlHelper version of the component supports declarative initialization.
Basic Configuration
The following example demonstrates how to configure the tile size, columns, Change event, and palette colors.
