Hi,

I have a infopath 2007 browser enabled form with a button and an ID field(and several other controls). Please let me know how to fetch a sharepoint list item filterd by the ID field value and populate other controls available on the form by using minimum coding(preferably no coding). Please treat it as urgent.

Thanks in advance for any help provided.

you can do it by using "Query for data" in infoPath form. Please follow below steps :

1. Add a connection to the list 

2. Set a field Value : List ID (select from Data connection) = ID (on the form)

3. Query for data : select the List Data Connection

4. Now all the data in list data connection will be filtered. you can set any control value with this data connection field value.
