SQL Query Builder

Hi,

I am looking for a query builder tool which can be used in my .net application. The idea is I am trying to develop the .net application, which has a button on click of that, it has to open the query builder tool, on close of that tool, i want the bring that query from the sql builder tool to the .net application. Can anyone advise me the way of working the idea.

Thanks in advance,
