I`ve put in Sharepoint library more then 20000 record. Then I create secondary data source in my infopath form. After that I`ve launched it. In combobox I have seen only 30-50 records... Where the others ?

SharePoint list adapter limits the entries to the number in the SharePoint view. If your default SharePoint view is limited to 100 (which is the default), then that's what you will see. To modify the number in the default view, go to modify columns and settings, click on the default view and scroll down to the bottom.

Ok. Thank you vary much. One more question.
I have a task:
Conditions:
1) Document library "LargeLib" in Sharepoint has 10000 documents.
2) User create some document D1 in some library "TempLib" and he wants to link D1 to some document in "LargeLib".
I create a combobox wich references to "LargeLib". But if I want to user put some mask in editbox, click to the button (For example "Find") and I make search! If there is one document - that`s ok, but if my script "SELECT * FROM documents WHERE name LIKE mask%"
will find more then one record??? I want to show all founded stuff in Dialog windo or in some new list, wich would be a modal... Is it posibile?

P.S. I hope you`ve understood my question.... :)
