Hi,
I am trying to add a custom context menu to a Grid control as follows:


@(Html.EJ().Grid<Object>("FlatGrid")
              .AllowPaging()

             .ContextMenuSettings(contextMenu =>
             {
                 contextMenu.EnableContextMenu().CustomContextMenuItems(new List<string>() { "MyMenuItem" });            
             })
            .ClientSideEvents(eve => { eve.ContextClick("contextclick").RightClick("rightclick").ContextOpen("contextopen"); })            
              .Columns(col =>
              {
                  col.Field("BookingCode").HeaderText("Booking Code").Add();               
                  col.Field("BookingDate").HeaderText("BookingDate").Format("{0:dd/MM/yyyy}").Add();
                  col.Field("CustomerReference").HeaderText("Customer Reference").Add();
                  col.Field("Note").HeaderText("Note").Add();
                  col.Field("StatusCode").HeaderText("Status").Add();
                  col.Field("TypeCode").HeaderText("Type").Add();                                   
              }))



but get the following compilation error:

Any help to resolve this issue would be much appreciated.

Hi Mahindra, 

Thanks for contacting Syncfusion support. 

We have modified the customContextMenuItems property to accept the values as the list of objects instead of list of strings. We also informed about this changes in Release notes of 14.1.0.41. Please refer to code example, sample and release notes for more information 
 
Code example: 
 

@(Html.EJ().Grid<OrdersView>("FlatGrid") 
        .Datasource((IEnumerable<object>)ViewBag.datasource) 
            
        
          .ContextMenuSettings(contextMenu => 
            { 
                contextMenu.EnableContextMenu() 
                    .CustomContextMenuItems(new List<CustomContexMenuItems>() { new CustomContexMenuItems() { Id = "MyMenu", Text = "MyMenuItem" } }); // CustomContext menu items 
                     
            }) 
 
        .AllowPaging() 
         .ClientSideEvents(eve => { eve.ContextClick("contextclick"); }) 
         .Columns(col => 
        { 
----------------------------------- 
        }) 
 
)
