This error cause because you are using 

   gdv.DataKeys[e.NewEditIndex].Value[0].ToString();

Here Value is type of object so you can not indexing on object.

to get data key value use Values instead of Value like this 

  gdv.DataKeys[e.NewEditIndex].Values[0].ToString();

Hope this helps..

Try this

IOrderedDictionary datakeyNames = gdv.DataKeys[0].Values;
string a = datakeyNames["FilterId"].ToString();
string b = datakeyNames["ItemId"].ToString();

Please note that you have to import System.Collections.Specialized
