How to convert from UserId to UserName in GridView?

i am using membership, and my GridView are using by choosing ObjectDataSource , In my ObjectDataSource i am using UserId, but when show the GridView i want the UserId changer UserName.How to do it? For example my some code,

<asp:TemplateField HeaderText="UserId"><ItemTemplate><%#Eval("UserId")%></ItemTemplate></asp:TemplateField>

You could write method that calls

MembershipUser u =Membership.GetUser(userID);.

username = u.UserName

Then call it from the template with <%# (String) MyGetUserNameMethod(String userid) %>

(declare the function protected string MyGetUseNameMethod in your code behind class)
