Dynamic View Panel has a property "target" in All Properties where you can select "_blank". This should add the attribute target="_blank"
to the links in first column. But, unfortunately, this works in Notes client only.
So, there is no property we just can set. Luckily, rendered links have an own class "xspLinkViewColumn" (see your source HTML example). With dojo.query
we can get all elements with this class and add the target attribute on client side.
Just add following event code to your XPage:
<xp:eventHandler
event="onClientLoad"
submit="false">
<xp:this.script><![CDATA[
dojo.query(".xspLinkViewColumn").attr("target", "_blank");
]]></xp:this.script>
</xp:eventHandler>
All links will get the attribute target="_blank"
this way and documents will be opened in a new browser tab.
