           int i= rc.Count;
           DataReader dr = rc[0];//get the first record
           RecordFieldCollection rfc= dr.Fields;//get the fields in the record
           i = rfc.Count;
           RecordField rf = rfc[1];//get the 1st field
      rf.Mapping = rf.Name; //now ,How to get the value of the field.

What is your overall goal here? as in, what is your button hoping to do?

You can get the value of an item in a store more easily on the client side by calling something like this in your js.

var myValue = myStore.data.items[i].data.myFieldName

You could then pass that to the server side for processing using something like:

Ext.net.DirectMethods.myServerSideMethod(myValue);

If you can elaborate a little on your goal it would be easier to suggest a suitable approach.
