Hi BanGotti,

There are blogs and tutorials all over the Internet concerning this. Just do a search for "InfoPath Performance" and you should find plenty of hints. Here's some of mine:

- Add calls to thisXDocument.View.DisableAutoUpdate() and thisXDocument.View.EnableAutoUpdate()

- Switch views when doing a lot of heavy XML moving

- Use a secondary DOM to do XML manipulation, then mirror into the Main DOM in one action

The reason for the big perf hits is because InfoPath does a lot of schema validation on the Main DOM. Moving to a secondary DOM curtails all of this validation and provides a huge perf boost.

Hello,

I m working on an InfoPath solution where I had to add and delete nodes using the managed code. However everytime I do this kind of operation, it takes a large amount of time (6 to 7 sec).

For exemple, my program allows the user search a list of information by clicking on a button, this information is then displayed in a list box (a list of nodes generated by the managed code).

My algorithm for the research:

1: if nb of nodes >0 THEN remove all nodes

2: if nb of nodes >1 THEN add N nb of nodes desired

3: add N strings in N nodes

I would like to know whether there is a way to make it quicker?

and if not Why is InfoPath so slow everytime we add or remove some nodes? (it is only XML and XSLT is n't it?)

Thanks.
