Cannot reference non-static field in RowRemoving on Datagrid

[LouiseAJensen]

I'm experiencing the exact same issue as is described here:
#570

I'm getting this error:
A field initializer cannot reference the non-static field, method, or property 'DepartmentOverviewPage_.DeleteCase(string)'

I have:

private Action<CancellableRowChange<model.Department>> OnRowRemoving = o =>
{
    o.Cancel = DeleteCase(o.Item.DepartmentID); // can't call non-static method
};

private bool DeleteCase(string id)  // If this is static, then I can't use JsRuntime
{
    bool confirmed = JSRuntime.InvokeAsync<bool>("confirm", "Are you sure?").Result;
    if (confirmed)
    {
        return true;
        // Delete!
     }
     return false;
}

My version is

You have this Action<CancellableRowChange<model.Department>>. What is the model.Department? Is it a data-type or is it a object field or member?

[LouiseAJensen]

It is the data-type that I'm using as a TItem in my Datagrid

I will need to see your models and a sample of DataGrid usage. If possible full reproducible sample would be great.

Hi , I have the same problem ¿ how can i solved this or view some example ?
On my Grid i use RowRemoving="@OnRowRemoving" and use exactly this code from issue
#570, but not working i have version 9.5.3

` private Action<CancellableRowChange> OnRowRemoving = o =>
{
o.Cancel = DeleteArea(o.Item.Code);
};

private bool DeleteArea(string usuarioCode)  
{
    bool confirmed = JS.InvokeAsync<bool>("Confirmar", "Confirmar", "¿Seguro que deseas quitar esta area?", "question").Result;
    if (confirmed)
    {
        var resp = Http.DeleteAsync($"DeleteUsuarioArea/{sessionTest.TokenAplicacion}/{usuarioArea.Code}");
        var data = Http.GetFromJsonAsync<List<UsuarioArea>>($"GetUsuarioArea/{sessionTest.TokenAplicacion}/{tempUsuario.usuarioSAP}");
        lstUsuarioArea = data.Result.Where(x => x.USER_CODE == tempUsuario.usuarioSAP).ToList();
        lstAreaToAdd = lstArea.Where(x => !data.Result.Any(z => z.U_SP_IdArea == x.Code)).ToList();
        StateHasChanged();  
        return true;
    }
    return false;
}`
