Events

Updated on Oct 1, 2026

This article explains the events available in the Telerik Color Palette for Blazor:

• OnChange
• ValueChanged
• OnBlur

OnChange

The OnChange event represents a user action - confirmation of the current value. It fires when the user clicks, taps or presses Enter to select a color, or when the component loses focus. It does not prevent you from using two-way binding for the Value.

Handle OnChange and use two-way binding for the Value

Example

View Source

Loading ...

The event is an EventCallback. It can be synchronous and return void, or asynchronous and return async Task. Do not use async void.

The OnChange event is a custom event and does not interfere with bindings, so you can use it together with models and forms.

ValueChanged

The ValueChanged event fires upon every change (selection of color) in the component. Its main purpose is to provide two-way biding of the Value.

Handle ValueChanged

Example

The event is an EventCallback. It can be synchronous and return void, or asynchronous and return async Task. Do not use async void.

OnBlur
