I'm a little confused so sorry for the questions...
1) Is this a webservice type app where data is being queried and then
transferred to the PDA to view or is the database actually residing on the
PDA?

2) Are you using datasets to store the data in order to display in your form
elements?

3) I'm a little confused about the comments of storing the data in
sqlserver db and then asking if things would speed up if they were in
sqlserver db. Either way, the datasets are going to be the middle ground
for storing the data for your components.

What types of searching/sorting are you doing that is slow? I think maybe a
little more info on what your app is doing might help provide a better
answer for you...

Sorry if I missed something that caused me to be more confused than
necessary...
