DIsable some menu items in SfGrid ContextMenu

[Salvatore]

Hi,

how to disable a single or more menu items in SfGrid ContextMenu?

I tried to rebuild the menu every time the OpenContextMenu event happens but this slows down the display of the menu a lot so I don't think it's the right way.

There is no enable or similar field in the ContextMenuItemModel object to use.

how can i fix it?

thanks

@using Syncfusion.Blazor.Grids 

 

<SfGrid ID="Grid" DataSource="@Orders" AllowSorting="true" AllowPaging="true" ContextMenuItems="@(new List<object>() { "AutoFit", "AutoFitAll", "SortAscending", "SortDescending","Copy", "Edit", "Delete", "Save", "Cancel","PdfExport", "ExcelExport", "CsvExport", "FirstPage", "PrevPage","LastPage", "NextPage"})"> 

    <GridPageSettings PageSize="8"></GridPageSettings> 

    <GridEvents ContextMenuOpen="ContextMenuOpened" TValue="Order"></GridEvents> 

    <GridEditSettings AllowEditing="true" AllowDeleting="true"></GridEditSettings> 

    <GridColumns> 

        <GridColumn Field=@nameof(Order.OrderID) HeaderText="Order ID" IsPrimaryKey="true" TextAlign="TextAlign.Right" Width="120"></GridColumn> 

        <GridColumn Field=@nameof(Order.CustomerID) HeaderText="Customer Name" Width="150"></GridColumn> 

        <GridColumn Field=@nameof(Order.OrderDate) HeaderText=" Order Date" Format="d" Type="ColumnType.Date" TextAlign="TextAlign.Right" Width="130"></GridColumn> 

        <GridColumn Field=@nameof(Order.Freight) HeaderText="Freight" Format="C2" TextAlign="TextAlign.Right" Width="120"></GridColumn> 

    </GridColumns> 

</SfGrid> 

 

@code{ 

    public List<Order> Orders { get; set; } 

 

    public void ContextMenuOpened(ContextMenuOpenEventArgs<Order> args) 

    { 

#pragma warning disable BL0005     

 

        for (var i = 0; i < args.Items.Count; i++) 

        { 

            if (args.Items[i].Id == "Grid_cmenu_Edit" && args.Column.Field == "Freight") 

            { 

                args.ContextMenuObj.Items[i].Disabled = true; 

            } 

        } 

#pragma warning restore BL0005       

 

    } 

 

    protected override void OnInitialized() 

    { 

        Orders = Enumerable.Range(1, 75).Select(x => new Order() 

        { 

            OrderID = 1000 + x, 

            CustomerID = (new string[] { "ALFKI", "ANANTR", "ANTON", "BLONP", "BOLID" })[new Random().Next(5)], 

            Freight = 2.1 * x, 

            OrderDate = DateTime.Now.AddDays(-x), 

        }).ToList(); 

    } 

 

    public class Order 

    { 

        public int? OrderID { get; set; } 

        public string CustomerID { get; set; } 

        public DateTime? OrderDate { get; set; } 

        public double? Freight { get; set; } 

    } 

}
