Change Group dynamically

[José paula]

Hello Team, i have a problem. I want to change the parameter GroupBy on a ListView, the thing is i want to change it dynamically when i click on a button, but it doesn't work.

When the component is initialized i set the parameter to one of the properties of the class, and it works, the listview is grouped. But when i click the button and i change the value of the parameter to another property, it does nothing, there is no visual change.

This is my code, i know that some parts are missing and got some hard-coded, but its just to make the group to work:

<SfListView @ref="listView" TValue="Email" DataSource="@emails">


<ListViewFieldSettings Id="email_id" Text="asunto" GroupBy="@agrupacion"></ListViewFieldSettings></SfListView>




<SfButton OnClick="Change">Change Group</SfButton>




public class Email   


{       


public int email_id { get; set; }       


public string de { get; set; }       


public string para { get; set; }       


public string asunto { get; set; }       


public string cuerpo { get; set; }       


public DateTime fecha_recepcion { get; set; }

}

public string agrupacion { get; set; }

private List<Email> emails { get; set; }

private SfListView<Email> listView { get; set; }




private void Change()       


{   


       agrupacion = "fecha_recepcion";


}

protected override async Task OnInitializedAsync()


{           


agrupacion = "para";       


}

Thank you for your time and i hope you can help me.
