You are using javascript in style tag which is not executed. You can use javascript on body onload event or jquery document.ready event to execute your script.

You are using 2 digit year and you would be getting 4 digit year, you need to change 11 to 2011.

Using Javascript

<body onload="CallTrShowHIde();">
    <table>    
      <tr id="tr1"  onload='alert("ac")' ><td>hello123</td></tr>
    </table>
</body>

function CallTrShowHIde()
{
      var year = '<%= DateTime.Now.Year %>';
      if (year == 2012)
            document.getElementById('tr1').style.display="none";
        else
            document.getElementById('tr1').style.display = "inline";  
 }

Using jQuery. 

<tr id="tr1">
     <td>Show or hide </td>
</tr>

 $(function () {
        var year = '<%= DateTime.Now.Year %>';
        if (year == 2012)
            $('#tr1').hide();
        else
            $('#tr1').hide();
 });

Asp tags come in a variety of flavors. The code you've written is correct but because you're using the wrong asp tags, nothing shows up.

This is the tag you want to use: <%= %> most useful for displaying single pieces of information

This is the tag you're currently using: <%# %> Data Binding Expression Syntax This doesn't work because you're not using data binding, you're just echoing a string.

DateTime.Now.Year should probably be DateTime.Now.Month
