I'm using the ej:Grid and I want to add Custom Context Menu.
Why do I get this error: Unknown server tag 'ej:CustomContexMenuItems'.?

My page:
<%@ Register assembly="Syncfusion.EJ.Web, Version=14.1460.0.46, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" namespace="Syncfusion.JavaScript.Web" tagprefix="ej" %>

<ej:Grid ID="Grid1" runat="server" AllowTextWrap="true" AllowPaging="true" AllowResizing="true" AllowSorting="true" AllowFiltering="true">
    <ClientSideEvents QueryCellInfo="GridQueryCellInfo" RecordDoubleClick="RecordDoubleClick" ContextClick="contextClick"/>
    <ContextMenuSettings EnableContextMenu="true" DisableDefaultItems="true">
            <ej:CustomContexMenuItems Id="clear" Text="Clear Selection" />

Hi Tomer, 

Thanks for contacting Syncfusion support. 

We checked your code example and found that the issue is due to the missing reference of the Syncfusion.JavaScript.Models namespace in the page. The ej:CustomContexMenuItems is available in Syncfusion.JavaScript.Models  namespace from Syncfusion.EJ assembly. So,  please add the below line either in your ASPX page or web.config to resolve this issue. 
<%@ Register Assembly="Syncfusion.EJ, Version=14.1460.0.46, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" namespace="Syncfusion.JavaScript.Models" TagPrefix="ej" %> 
<add namespace="Syncfusion.JavaScript.Models" assembly="Syncfusion.EJ, Version=14.1460.0.46, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" tagPrefix="ej" />
