Hello, I have the following problem: I have several records in datagrid and I want the moment I select a record and right click on it, a menu with options for the selected line appears. The only options in this menu are delete, details and print. I tried a solution that passed me another question that I did, but it did not work, because it enabled the menu anywhere in the datagrid that I clicked with the right mouse button

Hello Anurada, I will give you two solutions please check it and use as you needed.

Solution 1 : In order for ContextMenu to only appear when a line is selected, add this ItemContainerStyle to your ContextMenu.
<ContextMenu.ItemContainerStyle>
    <Style TargetType="{x:Type MenuItem}">
        <Style.Triggers>
            <DataTrigger Binding="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ContextMenu}}, Path=PlacementTarget.SelectedItems.Count}" Value="0">
                <Setter Property="Visibility" Value="Collapsed" />
            DataTrigger>
            <DataTrigger Binding="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ContextMenu}}, Path=PlacementTarget.SelectedItems.Count}" Value="1">
                <Setter Property="Visibility" Value="Visible" />
            DataTrigger>
        Style.Triggers>
    Style>
ContextMenu.ItemContainerStyle>
The most correct would be ContextMenu appear with your disabled items:
<ContextMenu.ItemContainerStyle>
    <Style TargetType="{x:Type MenuItem}">
        <Style.Triggers>
            <DataTrigger Binding="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ContextMenu}}, Path=PlacementTarget.SelectedItems.Count}" Value="0">
                <Setter Property="IsEnabled" Value="False" />
            DataTrigger>
            <DataTrigger Binding="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ContextMenu}}, Path=PlacementTarget.SelectedItems.Count}" Value="1">
                <Setter Property="IsEnabled" Value="True" />
            DataTrigger>
        Style.Triggers>
    Style>
ContextMenu.ItemContainerStyle>
Solution 2: You need to create a ContextMenu in your datagrid and put the options in it. It looks something like this:
<DataGrid Name="dataGrid">
    <DataGrid.ContextMenu>
       <ContextMenu>
          <MenuItem Header="Excluir" Click="MenuItemExcluir_Click"/>
          <MenuItem Header="Detalhes" Click="MenuItemDetalhes_Click"/>
          <MenuItem Header="Imprimir" Click="MenuItemImprimir_Click"/>
       ContextMenu>
    DataGrid.ContextMenu>
DataGrid>
For each action in this menu will have a Click event, in it you will be able to identify which item was clicked and continue processing what you need to do.

have you tried below code
private void dataGridView1_MouseClick(object sender, MouseEventArgs e)
{
    if (e.Button == MouseButtons.Right)
    {
        ContextMenu m = new ContextMenu();
        m.MenuItems.Add(new MenuItem("Cut"));
        m.MenuItems.Add(new MenuItem("Copy"));
        m.MenuItems.Add(new MenuItem("Paste"));

        int currentMouseOverRow = dataGridView1.HitTest(e.X,e.Y).RowIndex;

        if (currentMouseOverRow >= 0)
        {
            m.MenuItems.Add(new MenuItem(string.Format("Do something to row {0}", currentMouseOverRow.ToString())));
        }

        m.Show(dataGridView1, new Point(e.X, e.Y));

    }
}
