    You appear to be reseting the datasource in a loop, no idea why you would do this as only the last one would ever remain long enough to see it and if there where no match to the last one then you may see a blip of data then an empty grid.

    You should probably rethink your logic here,

    I am not sure what you are trying to do, are you trying to display all records from one table where a column matches a value in another, just one record. Try to explain what you are wanting to do in some detail so as to paint a clear picture for us and then I will see what I can do.
