Hi
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">
        <CustomContextMenuItem>
            <ej:CustomContexMenuItems Id="clear" Text="Clear Selection" /> 
        </CustomContextMenuItem>
    </ContextMenuSettings>
</ej:Grid>

Thanks,
   Tomer

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. 
 
 
ASPX 
<%@ Register Assembly="Syncfusion.EJ, Version=14.1460.0.46, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" namespace="Syncfusion.JavaScript.Models" TagPrefix="ej" %> 
(or) 
Web.config 
 
<add namespace="Syncfusion.JavaScript.Models" assembly="Syncfusion.EJ, Version=14.1460.0.46, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" tagPrefix="ej" /> 
 
 

Regards,
