problem with gridview

[jwrz200t]

Iam new to asp.net and Iam trying to bring my LDAP values on to a grid view. When I run my application iam not able to see the grid (the page turns up empty) what could be the possible reason??


public DataSet Userlogin(string sFilter, string[] columns, string path, bool useCached)

{

// trying to retrieve data from cache

string ulid = Session["id"].ToString();

string password = Session["password"].ToString();

HttpContext context = HttpContext.Current;

DataSet usersDS = (DataSet)context.Cache[sFilter];

if ((usersDS == null) || (!useCached))

{

//setup searching entries

DirectoryEntry deParent = new DirectoryEntry(path, ulid, password);

deParent.AuthenticationType = AuthenticationTypes.Secure;

DirectorySearcher ds = new DirectorySearcher(deParent, sFilter, columns);

ds.PageSize = 1000;

using (deParent)

{

//setup dataset that will store the results

usersDS = new DataSet("userDS");

DataTable dt = usersDS.Tables.Add("users");

DataRow dr;

// adding each property as a column

foreach (string prop in columns)

{

dt.Columns.Add(prop, typeof(string));

}

using (SearchResultCollection src = ds.FindAll())

{

foreach (SearchResult sr in src)

{

dr = dt.NewRow();

foreach (string prop in columns)

{

if (sr.Properties.Contains(prop))

{

dr[prop] = sr.Properties[prop][0];

}

}

dt.Rows.Add(dr);

}



}

}

// cache it for later, with 3 minutes sliding window

context.Cache.Insert(sFilter, usersDS, null, DateTime.MaxValue, TimeSpan.FromSeconds(180));

}

return usersDS;
}

protected void Page_Load(object sender, EventArgs e)

{
lblulid.Text = Session["id"].ToString();

string username = Session["id"].ToString();

string query = "(|(cn=" + username + ") (userPrincipalName= " + username + "ad.ilstu.edu))";

string[] columns = new string[] { "givenname", "sn", "physicalDeliveryOfficeName", "telephoneNumber", "mail", "cn" };

string ldapPath = "LDAP:// ";

GridView1.Visible = true;

DataSet ds = Userlogin(query, columns, ldapPath, true);

GridView1.DataSource = ds;

GridView1.DataBind();

}


<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True"

AutoGenerateColumns="true" CellPadding="4" ForeColor="#333333" GridLines="None"

Style="z-index: 100; left: 161px; position: absolute; top: 211px" EnableViewState="true" >
