Question: Here we are again with the next problem in sorting.

this is a follow up question to [this question](https://stackoverflow.com/questions/975712/asp-net-gridview-sorting-with-linq-result)

I have now made a type to contain the data I need.
however, when I try to fetch the data FROM the gridview it returns null, which means I can't sort anything that is not there in the first place...

any ideas why this returns null ...

```
IEnumerable<JointServerData> data = gvServers.DataSource;
var sorted = data;
switch (p)
   {
       case "domain":
            sorted = data.OrderBy(o => o.DomainName);
            break;
       default:
            break;
    }
gvServers.DataSource = sorted;
gvServers.DataBind();

```

above is what I'm trying to do ...

Answer: 
Without seeing all your code I'd have to assume that this is a PostBack issue. Website's are intrinsically stateless and you need to resolve this by either caching information between page requests or retrieving the data each time.
Try to set data binding in Init event of control.
