Disable Caching: SetNoCache vs SetCachability vs Expires vs AddHeader("pragma", "no-cache"); Urs Enzler19-Sep-07 20:08 Urs Enzler 19-Sep-07 20:08  I'm a bit confused. Searching the web for a solution to disable caching, I found several answers to this question. Unfortunately, I found several different answers all containing a mix of - Response.Expires - Response.Cache.SetNoStore - Response.AddHeader("pragma", "no-cache"); - Response.Cache.SetCacheability(HttpCacheability.NoCache); And secondly the documentation in MSDN is not quite clear, what every method exactly does. Maybe someone can help me understand? Thanks in advance Urs -^-^-^-^-^- no risk no funk ................... please vote ------> Re: Disable Caching: SetNoCache vs SetCachability vs Expires vs AddHeader("pragma", "no-cache"); Guffa19-Sep-07 21:30 Guffa 19-Sep-07 21:30  All that those commands do is to add properties to the http header of the page. Most examples is just a collection of everything ever found on the matter, setting the same properties over and over in different ways using different values overwriting each other. You just have to find out what headers you need, and set them. Maybe this is helpful: http://www.seoconsultants.com/articles/1000/cache-control.asp[^] The ultimate source (although a lot to read) on how caching works is of course the RFC: http://www.w3.org/Protocols/rfc2616/rfc2616-sec13.html#sec13[^] --- single minded; short sighted; long gone; databinding error [modified] Sonia Gupta19-Sep-07 19:55 Sonia Gupta 19-Sep-07 19:55  i was binding the data with the datagrid.i am binding the data through three tables.all the tables hava a common column field .i am using the hyperlink control to pass the id to another page.id belongs to the column name (which is common to all the tables that i mentioned a while ago).now the problem is i am getting the following error. <b>DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'vcode'.</b> i am using the following code <asp:HyperLink ID="id" runat="server" Text='<%#DataBinder.Eval(Container.DataItem,"Pass")%>' NavigateUrl='<%#"DetailInformation.aspx?vcode=" + DataBinder.Eval(Container.DataItem,"vcode")%>'></asp:hyperlink> problem is occuring in vcode Soniagupta1@yahoo.co.in -- modified at 2:51 Thursday 20th September, 2007 Re: databinding error Imran Khan Pathan19-Sep-07 20:11 Imran Khan Pathan 19-Sep-07 20:11  Here vcode is considered as datafield name. try this NavigateUrl='<%#"DetailInformation.aspx?vcode="+DataBinder.Eval(Container.DataItem,"vcode")%>' Best Regard Pathan --------------------------------------------------- Re: databinding error Abolfazl Sheikhloo19-Sep-07 20:38 Abolfazl Sheikhloo 19-Sep-07 20:38  a filed with the name 'vcode' does not exists in the grid datasource u must select vcode too.

Re: Email in ASP.NET rahul.net1119-Sep-07 20:31 rahul.net11 19-Sep-07 20:31  This is a network related error. Your application cannot connect to the mail server specified. SmtpMail.SmtpServer 1)Is a valid SMTP Server 2)Check to be sure the server System.Web.Mail is executing on can connect to the mail server. Some times firewalls or proxy servers can get in the way. 3)Try specifying the value by IP address. Poor DNS resolution can sometimes hinder name lookups. 4)Make sure the that the mail server is running at port 25. 5)If you did not specify a SmtpMail.SmtpServer property, or if SmtpMail.SmtpServer points to "localhost" (or the equivalent), be sure the SMTP Service is running on port 25. For testing purposes change the MailMessage.From and MailMessage.To properties to an address that exists on SmtpMail.SmtpServer. Some times this exception is thrown, when it really is a relay issue. also try this SmtpMail.SmtpServer.Insert( 0, "127.0.0.1 or your mail server name here") Also make sure Anonymous access is allowd.
