The Telerik UI FlatColorPicker HtmlHelper for ASP.NET MVC is a server-side wrapper for the Kendo UI FlatColorPicker widget.
The FlatColorPicker is the HSV color selector which is used by default in the kendo.ui.FlatColorPicker 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>
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 MVC declaration.
<script>
$(function() {
// The Name() of the FlatColorPicker is used to get its client-side instance.
var flatcolorpicker = $("#flatcolorpicker").data("kendoFlatColorPicker");
});
</script>
