Hi Saurav,
I think that the problem here is that the Repeater web part does not work with Data source web parts. The data sources are really for loading the data from somewhere and Repeater is for BOTH loading data and displaying them at the same time.
If you want to use Data source web parts then you need to connect them to Basic repeater web part where you need to connect the data source with the basic repeater via their IDs. As you can see the Basic repeater does not have any "Where", Order by" or other conditions because it wouldn't make sense as data is retrieved via external data source.
