Base 64 Bit Encoding and Decoding

string Order = “Ord12011982″;
#region Encode
byte[] Enc = ASCIIEncoding.UTF7.GetBytes(Order);
string EncString = Convert.ToBase64String(Enc);

#endregion
#region Decode
byte[] Dec = Convert.FromBase64String(EncString);
string b = ASCIIEncoding.UTF7.GetString(Dec);
#endregion
Tou can al use UTF8,UTF32

Instead of DataBinder.Eval use DataRowView

<%# ((DataRowView)Container.DataItem)["name1"] %>

This One  is the  Best One……..While using DataBinder.Eval()

If your Record exeecds than 100 Rows..It Will become a Problem.More duplication Will Occur.

Difference between Hyperlink and LinkButtton in ASp.NET

To the Web page visitor, a HyperLink control and a LinkButton control look identical. However, there is a significant difference in functionality.

The HyperLink control immediately navigates to the target URL when the user clicks on the control. The form is not posted to the server.

The LinkButton control first posts the form to the server, then navigates to the URL. If you need to do any server-side processing before going to the target URL, use a LinkButton.

On the other hand, if there is no server-side processing necessary, don’t waste a round trip and use the HyperLink control.
