Two-way binding is having a bidirectional data flow, i.e., passing the value from the property to the UI and then from the view (UI) to the property. Blazor provides support for two-way binding using the bind attribute.
Syntax for creating two-way binding property:
@bind-{Parameter_name}={Variable_name}
For e.g.., in InputDate, a form component can be used to achieve two-way data binding with input date values in a Blazor application.
Refer to the following code for more details.
<EditForm Model="@_test">
<InputDate @bind-Value="_test.DateValue" />
</EditForm>
<br />
<p>Selected Date: @_test.DateValue.ToLongDateString()</p>
@code {
public class TestClass
{
public DateTime DateValue { get; set; }
}
private TestClass _test = new TestClass();
}
In this example code, when the value of _test.DateValue is changed in the code or user changes the date in the InputDate component, the same will be reflected in the paragraph, “Selected Date”.
