If you ever wondered how you can do this “without code” J you can do it by placing two WebParts on a SP page; an InfoPath Form WebPart and a Query String Filter WebPart. You then make a connection between the two passing the value from the Query String Filter to the InfoPath form WebPart.
Note the following:
- This will not work for “lookup” fields if you use the default SP list InfoPath form (That’s Why I thought you can’t do it originally for lookups). However, you can expose the “lookup” dropdown field if you create a new InfoPath form using the method below.
- Make sure you add the “field” in your InfoPath to the list of allowable fields to be used in connections.
And here is how you can do it with Code behind.
