ColorPicker Events
This article describes the available events of the Telerik ColorPicker for Blazor.
OnChange
The OnChange event fires when the user commits their selection with:
- Apply or Cancel button click
- Enter keypress
- Blur action (popup close)
Note that the OnChange event may also fire when the actual selected color has not changed.
The event type is EventCallback<object>. The OnChange event does not prevent two-way binding for the Value attribute.
ValueChanged
The ValueChanged event fires when the user selects a new color and the component value changes.
The event type is EventCallback<string>. Using ValueChanged requires one-way binding for the Value attribute and manual value update in the event handler.

The event type is EventCallback<ColorPickerView>. Using ViewChanged requires one-way binding for the View attribute and manual value update in the event handler.
