change function so it will only get a part of the users

Question

HI ,

 

Ive got the following webapp. using asp.net /c# .

Now when we go to the userpage. The page_load will be loaded.

IN the paige load there is a function to check if it is a postback. If it isn't a postback a function is called to get the users and show them in a repeater. However. The first time it loads it get all the users. the second time it doesn;t get the users ( because, it is a postback). Olso every page shows 10 users ( for now) we can change that by editing the pageSize.

 

How can i change te code, so it will only get the users it need ( not all of them). here is the code. please give me some advice or tips how to change the code.

 

 protected void Page_Load(object sender, EventArgs e)
        {

            try
            {
                if (PortalApplication == null)
                    return;

                if (!IsPostBack)
                    FillRptUsers();

            }
            catch (Exception ex)
            {
                PortalApplication.HandleException(ex);
                ShowFailureText();
            }
        }

public void FillRptUsers()
        {
            var serviceProviderId = PortalApplication.User.serviceProviderId;
            var groupId = PortalApplication.User.groupId;
            var users = PortalApplication.GetGroupUsers(serviceProviderId, groupId, UserFilter.Text, (CurrentPage - 1) * PageSize, PageSize);
}
