c# - Will not open a new tab in browser -

I'm afraid someone can help me, I'm trying to open hyperlinks in another tab within IE but Whatever I have tried does not want to work. Due to client requests, I am working in ASP.NET C #.

My code looks like this:

  & lt; A href = "inv_dets.aspx? Invid = & lt;% # DataBinder.Eval (container.detime," invoiceIDID ")%> & gt; View & lt; / A & gt;   
 How can anyone change this code so that it opens inside a new tab within IE? P>  
 
 
  & lt; A target = "_ blank" href = "inv_dets.aspx? Invid = & lt;% # DataBinder.Eval (container.detime," invoice ID ")%> & gt; View & lt; / A & gt;
