Add the ability to use a function to show/hide toolbar buttons like it is for column commands

Hi,

The Kendo UI Grid has the ability to conditionally hide/show the command columns. But in order to hide some buttons from the toolbar, you need a dataBound handler. It will be useful to hide the "Create" button from non-admins, but be able to show the PDF and Excel Export or hide the entire toolbar.

toolbar: [
    { name: "create", visible:function(){ return isAdmin; } },
    { name: "reports" , visible: function(){ return isManager }},
    { name: "cancel" }
  ],

Currently, we need to use this dataBound handler:

.Events(e=>e.DataBound("onDataBound"))     
  
 function onDataBound(e) {
   if (true) { // the condition against which you want to show/hide the toolbar
     this.element.find(".k-grid-toolbar").hide(); // hides the entire toolbar
     this.element.find(".k-grid-add").hide(); // hides just the Create button
  }
}


Thank you in advance,
Ken

Hi,

For the ASP.NET MVC and Core Grid, we can add a condition:

@{
        // check if the user should have access
	var isAdmin = false;
}

.ToolBar(t =>
{
         if (isAdmin)
         {
             t.Create();
             t.Pdf();
         }
         else
         {
             t.Pdf();
         }
})

The other option is to use a ToolBar template and pass a condition there. This approach is also valid for the jQuery Grid:

http://demos.telerik.com/aspnet-mvc/grid/toolbar-template

I will mark this item as Unplanned and if it gains enough popularity, the Product Management team will consider it for future implementation.

Thank you both for taking the time to share your thoughts.

Would be nice if you could do it for the whole toolbar as well as item by item.
