ViewState in Sessions

by Moridin8 20. January 2008 20:07

Yes it's been a while since I have been around.  Moving to the USA and all that... you know?

Anyway, I am getting a little tired of people mis-aligning the old ViewState in session thing - mostly due to bad implementations or 'attempts'.  So here is how it should be done:

Create a browser file:

<browsers>
   <browser refID="Default">
      <controlAdapters>
         <adapter controlType="System.Web.UI.Page" 
                     adapterType="YourNM.PageStateAdapter" />
      </controlAdapters>
      <capabilities>
         <capability name="RequiresControlStateInSession"  
                        value="true" />
      </capabilities>
   </browser>
</browsers>

Then you create the class thus:

public class PageStateAdapter : PageAdapter
{
    public override PageStatePersister GetStatePersister()
    {
        return new SessionPageStatePersister(this.Page);
    }
}

 


And voila... No need to worry about which page uses which session cached viewstate as it is all handled by the SessionPageStatePersister. 

No worries...

MeMy name is Matt and I am the current tenant of this small corner of the internet.
