    Namespace: DevExpress.Blazor

    Assembly: DevExpress.Blazor.v25.1.dll

    NuGet Package: DevExpress.Blazor

    Declaration

    [Parameter]
    public Expression<Func<string>> TextExpression { get; set; }

    Property Value

    Type Description
    Expression<Func<String>>

    A lambda expression that identifies the bound value.

    Remarks

    You can add a Search Box to Blazor’s standard EditForm component to validate the Text property value. In this case, the TextExpression property is used to obtain metadata about the value bound to the Text property.

    You should specify the TextExpression property if you handle the TextChanged event and cannot use two-way binding.

    The TextExpression property is set internally if you use the @bind attribute for the Text property to implement two-way binding.

    The following exception occurs if you do not use two-way binding or the TextExpression property:

    DevExpress.Blazor.DxSearchBox requires a value for the ‘TextExpression’ property. It is specified automatically when you use two-way binding (‘bind-Text’).
