Contextmenu enabled anywhere in the datagrid on right mouse button

Question

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)); } } https://stackoverflow.com/questions/1718389/right-click-context-menu-for-datagridview
