Blazor @onValueChanged

Blazor is a web application development framework developed by Microsoft. It allows developers to build web applications using C# and .NET instead of JavaScript. Blazor @onValueChanged event is an important event used in Blazor applications.

What is @onValueChanged event

@onValueChanged is a Blazor event that is triggered when data is changed in an input component. The event is fired when the user interacts with the component and the data in the component is changed.

For example, if you have an input component in your Blazor application, and the user types something into the input field, the @onValueChanged event will be triggered. This event can then be used to update other parts of the application based on the new input.

How to use @onValueChanged event

To use the @onValueChanged event in your Blazor application, you need to attach it to the input component. Here's an example:

<input type="text" @bind="@MyString" @onValueChanged="ValueChanged"/> 

@code {
    public string MyString { get; set; }
        
    private void ValueChanged(string value)
    {
        // Do something with the new value
    }
}

In this example, we have an input component that is bound to the MyString property. The @onValueChanged event is attached to the input component, and it calls the ValueChanged method whenever the input value changes.

Conclusion

The Blazor @onValueChanged event is an important event in Blazor applications. It allows developers to create responsive and interactive web applications using C# and .NET. With this event, developers can easily update their application based on user input, making it a powerful tool for creating rich web applications.
