    </CardHeader>
    @if (vcomp == null)
    {
        <CardBody class="text-center">
            <img height="100" src="../../imag/loadingl.jpg" />
        </CardBody>
    }
    else
    {
        <CardBody Class="frtl">
            <div style="height:500px; overflow-y: scroll;">
                <DataGrid TItem="VCompany"
                          Data="@vcomp"
                          AllowSort=true
                          AllowFilter=true
                          ShowPager=true
                          PageSize="PageSize"
                          @bind-SelectedRow="@selectedVCompany"
                          Selectionchange="@SelectRowC"
                          IsBordered="true"
                          IsNarrow="true"
                          IsHoverable="true">
                    <ChildContent>
                        <DataGridCommandColumn TItem="VCompany">
