How can I close a TelerikContextMenu programatically?

[Víctor]

I have a DropDownList where each element has a button to open a TelerikContextMenu as such:

The problem is that sometimes the dropdown is closed and the menu not, like so:

Here is my code:

@namespace Appia.UiKit
@using Telerik.Extensions;
@using Appia.Entidades;
@using static Appia.Tests.Victor.TestWidget;
@inject IViewRepository ViewRepository

<TelerikDropDownList @ref="DropDownRef" TItem="ValueWrapper<string>" TValue="string" Data="ListOfViews" Filterable="true" FilterOperator="@StringFilterOperator.Contains"
                     FillMode="@ThemeConstants.DropDownList.FillMode.Flat" Class="" Width="min-content" ItemHeight="38"
                     Value="@ActiveViewId" ValueChanged="OnChange" OnClose="OnClose" AdaptiveMode="@AdaptiveMode.Auto">
    <ValueTemplate>@context.Text</ValueTemplate>
    <NoDataTemplate>No hay ninguna vista disponible</NoDataTemplate>
    
    <ItemTemplate>
        <div class="k-hbox w-100 k-border-bottom k-border-dark" >
            <div class="k-flex-grow k-align-self-center">@context.Text</div>
            <div @onclick:stopPropagation="true">
                <TelerikButton Icon="@(AppiaIcons.Stack)" OnClick="@HandleContextMenuButton" FillMode="@ThemeConstants.Button.FillMode.Flat"></TelerikButton>
            </div>
        </div>
    </ItemTemplate>
    <FooterTemplate>
        <div class="k-border-t-only" @onclick:stopPropagation="true">
            <TelerikButton Icon="@AppiaIcons.Favourite" Class="w-100 k-text-start" FillMode="@ThemeConstants.Button.FillMode.Flat">Establecer como predeterminada</TelerikButton>
            <TelerikButton Icon="@AppiaIcons.Compose" Class="w-100 k-text-start" FillMode="@ThemeConstants.Button.FillMode.Flat">Editar vista</TelerikButton>
            <TelerikButton Icon="@AppiaIcons.Globe" Class="w-100 k-text-start" FillMode="@ThemeConstants.Button.FillMode.Flat">Renombrar vista</TelerikButton>
            <TelerikButton Icon="@AppiaIcons.Duplicate" Class="w-100 k-text-start" FillMode="@ThemeConstants.Button.FillMode.Flat">Duplicar vista</TelerikButton>
        </div>
    </FooterTemplate>
    <DropDownListSettings>
        <DropDownListPopupSettings Height="430px" Width="min-content" Class="shadow-5" AnimationDuration="0"  />
    </DropDownListSettings>
</TelerikDropDownList>


<TelerikContextMenu @ref="@ViewItemMenuRef" Data="@ActionItems"></TelerikContextMenu>

@code {
    [Parameter] public ViewInstance ViewInstance { get; set; }
    public TelerikContextMenu<ActionItem>? ViewItemMenuRef { get; set; }
    public TelerikDropDownList<ValueWrapper<string>, string> DropDownRef { get; set; }
    public List<ValueWrapper<string>> ListOfViews { get; set; } = new();
    public bool IsCancelled = false;
    public string? ActiveViewId;

    public List<ActionItem> ActionItems { get; set; } = new()
    {
        new () { Text = "Activar", Icon = AppiaIcons.Eye },
        new () { Text = "Establecer como predeterminada", Icon = AppiaIcons.Favourite },
        new () { Text = "Editar", Icon = AppiaIcons.Compose },
        new () { Text = "Renombrar", Icon = AppiaIcons.Information },
        new () { Text = "Eliminar", Icon = AppiaIcons.Delete },
        new () { Text = "Duplicar", Icon = AppiaIcons.Duplicate }
    };

    protected override async Task OnInitializedAsync()
    {
        ActiveViewId = this.ViewInstance.ActiveView.Id;

        this.ListOfViews = await ViewRepository
            .ListAvailableAsync(this.ViewInstance.ActiveView.TipoDeVista, this.ViewInstance.ActiveView.EntityType)
            .ThenSelect(x => new ValueWrapper<string>(x.Id, x.Nombre))
            .Then( x => x.ToList() );

        await base.OnInitializedAsync();
    }

    public async Task OnRead(DropDownListReadEventArgs args) => await ViewRepository.ListAvailableAsync(ViewInstance.ActiveView.TipoDeVista, ViewInstance.ActiveView.EntityType, async db => await db.ToDataSourceReadEvent(args));

    public async Task HandleContextMenuButton( MouseEventArgs args )
    {
        IsCancelled = true;
        await ViewItemMenuRef?.ShowAsync( args.ClientX, args.ClientY );
    }

    public void OnClose( DropDownListCloseEventArgs args )
    {
        args.IsCancelled = IsCancelled;
        IsCancelled = false;
    }

    public void Close()
    {
        IsCancelled = false;
        DropDownRef.Close();
        IsCancelled = true;
    }

    public void OnChange( string args )
    {
        this.ActiveViewId = args;
        Close();
    }

}

 

Therefore I need a way to close the menu programaticlly that I will fire when the dropdown list is closed. 

I would als like to have listeners on the TelerikContextMenu to know when it's closed, this way I could close the dropdown.

How could I do that?

Thanks

Hi Victor,

Currently it is possible to close the ContextMenu with JSInterop. This feature request contains an example.
