ViewState and Server.Transfer Best practices

ViewState and Server.Transfer Best practices
 
Scenario :
 

 Server.Transfer("destiny.aspx",true); 

Above statement will cause ViewState is invalid exception
 
Reason :
 
By default EnableViewStateMac is set to true, and hence on every page life cycle , it tries to validate the value of the ViewState(for security reason) ,which is a part of forms collection(__ViewState - hidden field) and by ViewState design at any given point you can post to only one form...Hence in the prior case , it tries to compare the ViewState of the source with the destiny and hence the above mismatch happens :)
 
Best practices to Transfer the control to the other page without affecting the view state
 
Option 1
 
use
 

Server.Transfer("destiny.aspx",false);

 
- The Second parameter in the above statement is set to false , Hence it is not preserving the prvious page folrms collections..
 
Option 2
 
Passing Server control value between pages
