Events

The TelerikMediaQuery component for Blazor exposes events that allow you to respond to user actions and provide custom logic.

OnChange

The OnChange event fires to notify you whether the media query string provided to the Media parameter is matched by the browser. It fires when it matches, and when it stops matching.

Use the OnChange event to resize a parent container

@* Resize the parent container *@

<TelerikMediaQuery Media="@MediaQuery" OnChange="@OnChange"></TelerikMediaQuery>

<div style="width: @(IsSmallScreen ? "500px" : "100%"); height: 400px; border: 1px solid black">
    Shrink the browser to less than 767px to resize the container.
</div>

@code {
    private bool IsSmallScreen { get; set; }

    private string MediaQuery { get; set; } = "(max-width: 767px)";

    private void OnChange(bool doesMatch)
    {
        IsSmallScreen = doesMatch;
    }
}
