SegmentedControl Events

Updated on Oct 1, 2026

This article describes the ValueChanged event of the Telerik SegmentedControl for Blazor.

ValueChanged

The ValueChanged event fires when the user clicks an item and the selection changes. The event handler receives the new value as its argument. The application must update the Value parameter in the handler.

Use ValueChanged together with Value for one-way binding, or use @bind-Value for two-way binding.
