I created a new form in company and my new form has 4 textboxes.How can i access and read my textboxes' values using web services ?
I would suggest using the Advanced Developer Extensions or XRM... here is a link to the page on MSDN: http://msdn.microsoft.com/en-us/library/ff681559.aspx
Using Xrm you will get a usability similar to EF and the same coding strategy can be used when you upgrade to CRM 2011.
