I'm using windows authentication and I'm adding identity
impersonate="true".
And here is the behind code:

System.Web.UI.WebControls.TextBox st6=new
System.Web.UI.WebControls.TextBox();
st6=(System.Web.UI.WebControls.TextBox)e.Item.Cells[0].FindControl("txtname­");
SqlCommand myCommand=new
SqlCommand();myCommand.Connection=con;myCommand.CommandText="insert
into DashBoard (ObjectiveAchieved,Objective,MoodToday,Name) values
(@ObjectiveAchieved, @Objective,@MoodToday,@Name)";
myCommand.Parameters.Add(new SqlParameter("@Name",SqlDbType.Text));
string
DomainUser=System.Security.Principal.WindowsIdentity.GetCurrent().Name.Repl­ace("\
\","/");
System.DirectoryServices.DirectoryEntry ADEntry = new
System.DirectoryServices.DirectoryEntry("WinNT://"+DomainUser);
myCommand.Parameters["@Name"].Value=st6.Text=(ADEntry.Properties["FullName"­].Value.ToString());

Where could I be going wrong?
Thanks
