As per code you posted in your question, there seems no issue in code, But check if your table returning any value or not. But in the code mention in comment you have error in position as mentioned:

XML

<asp:Repeater ID="rptrmenu" runat="server">


                    <li>

                       <%#Eval("menu_name ")%></li>

You have not used the

<itemtemplate>

tag. Let me know if more help is required?

datatable returning the value also..but the same code work in aspx page.is there is any other way i can do it in master page?

Er. Puneet Goel 5-Apr-14 6:05am

Code is perfect. Just check that the container visibility in which you have written this code block on master page. If you still don't find the issue, can you please post the HTML code block ?
