How do you add a menu separator to a Syncfusion chart right click context menu?

This is a dynamic menu and can't be done directly in XAML.

We're using Syncfusion.Chart.WPF.DLL version 9.203.0.137 in a .net 4.0 WPF desktop application.

Here is a simplified version of our code to create the chart and right click menu.

Chart g = new SyncFusion.Windows.Chart.Chart();

..setup other chart properties

ChartArea chartArea = new ChartArea();

..setup other chart area properties

chartArea.IsContextMenuEnabled = true;
chartArea.ContextMenuType = ContextMenuTypes.Custom;

//add menu items to right click context menu

MenuItem m = new MenuItem();
m.Header = "Show test dialog";
m.PreviewMouseLeftButtonUp += new MouseButtonEventHandler(ShowTextDialog_OnClick);
chartArea.CustomContextMenuItems.Add(m);

//separator should go here

MenuItem m2 = new MenuItem();
m2.Header = "Show test dialog2";
m2.PreviewMouseLeftButtonUp += new MouseButtonEventHandler(ShowTextDialog2_OnClick);
chartArea.CustomContextMenuItems.Add(m2);

g.Areas.Add(chartArea);

Hi George,


We have analyzed your requirement, and there is no special support for adding a separator to the context menu. But your requirement can be achieved by overriding the datatemplate of contextmenuitem header as in below code snippet.


Code Snippet [Xaml]:







Code Snippet [C#]:

area.IsContextMenuEnabled = true;

area.ContextMenuType = ContextMenuTypes.Custom;

ContextMenu menu = new ContextMenu();

MenuItem seperator = new MenuItem();

seperator.Height = 7;

seperator.Width = 200;

seperator.VerticalContentAlignment = System.Windows.VerticalAlignment.Stretch;

seperator.HeaderTemplate = this.Resources["Seperator"] as DataTemplate;

seperator.Header = "Seperator Header";

menu.Items.Add("Rotate Series");

menu.Items.Add("Zomming");

menu.Items.Add(seperator);

menu.Items.Add("Print");

menu.Items.Add("Save");

area.ContextMenu = menu;


Based on your requirement we have created a simple sample, which you can download from the link below.

Thanks,
