Problem with Itunes

[DEKA2010]

every time I sync my Ipad with Itunes in my computer, Itunes always give 2 options, sync my Ipad but this action will also remove my apps in my Ipad, 2nd option is cancel, this means I can't add apps I download using Itunes, its so ridicules , or may be I set it up in the wrong way ? Please give me help to solve the issue

Use the transfer purchases option in iTunes when your iPad is connected.

Yeah I tried it, its only contain 3 books that I have already downloaded, not all the screen looks different, only screen no 4, some items can be transferred , some can not, soft n hard reset won't work, drag the items also didn't workout, but thank you anyway for sharing experience with me, I appreciate that
