Get Server side values to Client side

Question

Here i'm going to get Server side values to client side.

aspx

<a href="#" class="alert-link">Welcome <%=GetUserName();%></a> <-- problem in here

aspx.cs

public string GetUserName()
{
    string name;
    MembershipUser usr = Membership.GetUser();
    name = usr.UserName; //<-- Correct names come to here
    return name;
}

Answer 1

The aspx markup is invalid. You should not have a semicolon inside the ERB tag.

<a href="#" class="alert-link">
    Welcome <%= GetUserName() %>
</a>

Additionally consider checking for null .

public string GetUserName()
{
    var user = Membership.GetUser();
    if(user == null)
    {
        return "Anonymous";
    }

    return user.UserName;
}
