I have 2 gridviews, `gv1` and `gv2` and an `ObjectDataSource` with the id `ods1`. Both the gridviews are pointing to `DataSourceID="ods1"`.

My question is, how do I know in selecting event of an `ObjectDataSource` that which gridview has called `ods1`. I want to set input parameters based on which gridview has made a call to the `ods1`.
