How to show roles in ASP.NET?

Question

I am getting user list using Membership.GetAllUsers() function. And I bind this data in a grid view.

But I cannot find the roles information here. I need to show the roles in that grid view.

What should I do ?

Answer 1

Roles.GetRolesForUser(user)

UPDATE

This is going to be pretty slow if you have a lot of users

GridView.RowDataBound += new GridViewRowEventHandler(GridView_RowDataBound);

void GridView_RowDataBound(object sender, GridViewRowEventArgs e) {
    GridView gridview = (GridView)sender;
    if (e.Row.RowType == DataControlRowType.DataRow) {
        string username = DataBinder.Eval(e.Row.DataItem, "yourusernamecolumn").ToString();
        Literal c = new Literal();
        c.Text = Roles.GetRolesForUser(username).ToString(); //decide how you want to display the list
        e.Row.Cells[somecolumnindex].Controls.Add(c);
    }
}

It might be better to read straight from your role-to-member table.

Answer 2

Use RoleProvider.GetAllRoles().
