Try something like this
if (e.Row.RowType == DataControlRowType.DataRow)
YourClass object = (YourClass)e.Row.DataItem;
 LinkButton lnkbtn= (LinkButton)e.Row.FindControl("Lnk");
  lnkbtn.Visible = !Convert.ToBoolean(object.Value);   

Well, This will do the job for you as per your current implementation. use a Not ( ! ) Operator
<br />
Visible=<%# !(Convert.ToBoolean(Eval("IsNewRow"))) %>

Let me know if it work.
on gridview rowdatabound event you can add following code keep your <%# Bind(!"IsNewRow") %> which is as datakey field of gridview.

bool Isnewrow
if (e.Row.RowType == DataControlRowType.DataRow)

Isnewrow= Convert.ToBool(gridview.DataKeys[e.Row.RowIndex].Values[0]);

LinkButton lnkButton = (LinkButton)e.Row.FindControl("lnkViewDetails");

To add Isnewrow field as datakey of gridview

<asp:GridView ID="gridview1" AllowPaging="true"
AutoGenerateColumns="false" DataKeyNames="Isnewrow "
runat="server" ShowFooter="true"
