Answer 1

You cannot bind the user's identity declaratively in markup directly to the EntityDataSource. But there are basically two workarounds:

The first is the easier one but requires code-behind. You can use a generic asp:Parameter and set its value in code-behind to the user's identity:

Markup:

Code-behind:

protected void Page_Load(object sender, EventArgs e)
{
    MyEntityDataSource.WhereParameters["Username"].DefaultValue =
        User.Identity.Name;
}

The second way is to create a custom parameter. An example how to do that is shown here. Note: The example is based on a asp:SqlDataSource but it should work as well for an EntityDataSource if you make sure that you use WhereParameters in the EntityDataSource instead of SelectParameters in the SqlDataSource.
