Blazor Grid: How to disable context menu items based on clicked cell?

How do disable context menu items?

        public void ContextMenuOpened(ContextMenuOpenEventArgs<DeliveryNote> args)
        {
            foreach (var item in args.Items)
            {
                if (item.Id == "edit" && !args.Column.AllowEditing)
                {
                    item.Disable = false; //does not work
                    item.Hidden = false; //does not work
                }
            }
        }

I'm using     <PackageReference Include="Syncfusion.Blazor" Version="18.3.0.47" />

Hi Liero, 

Greetings from Syncfusion support. 

We suggest you to modify the Disabled property value in args.ContextMenuObj to achieve this requirement. Please refer and use the below codes to achieve this requirement. 

 
public void ContextMenuOpened(ContextMenuOpenEventArgs<Order> args) 
{ 
    foreach (var item in args.Items) 
    { 
        if (item.Id == "edit" && !args.Column.AllowEditing) 
        { 
            args.ContextMenuObj.Items[0].Disabled = true; 
        } 
        else if(item.Id == "edit" && args.Column.AllowEditing) 
        { 
            args.ContextMenuObj.Items[0].Disabled = false; 
        } 
    } 
} 


Please get back to us if you need further assistance. 

Regards,

Thanks. It works, but I'm getting: BL0005:Component parameter should not be set outside of its component.
