Hi Niklas,
Thanks for using Syncfusion products.
We suggest you to use ribbon Custom contents using the property ContentID with the
type "Custom" to create button with action link.
Please refer to the below code example
and sample,
[cshtml]
cntgrp.Id("btn1").ToolTip("anchor
button").Type(RibbonButtonType.Custom).ContentID("A1").Add();
<a id="A1" rel='nofollow' href="http://www.syncfusion.com">
<button id="btn">Anchor Button</button>// route link rel='nofollow' href with button
</a>
<script>
$("#btn").ejButton(); //To Render
EJ Buttton.
</script>
Sample: Ribbon
Regards,
Kavitha
