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.
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>
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.
