How to visible false Template field dynamically in asp.net

You can always bind the Visible property to a method on your .cs file.

But you can also use inline code like this:

<%
if (IsVisible())
{%>
   <asp:LinkButton ID="mylink" Text="Your link text"runat="server"> </asp:LinkButton>
<% }%>

You can condition the rendering of any asp.net or html code based on the logic on that IsVisible function. That could be implemented like this:

protected bool IsVisible()
{
     return Roles.IsUserInRole("admin");
}

You replace the function with the final code, in this case because is a simple return line, but well, that will depend on your back-end code.

Hope it helps.
