Narrative:

After performing a touch and go at the airport; I began my initial climb out to remain in the pattern for runway xx. There were several other planes in the pattern and a bonanza that had been calling in from the north to enter the pattern. On the climb out from the touch and go; I announced the CTAF that I was on the departure leg and remaining in the pattern climbing to 2;500 (1;500 AGL). At approximately 1;000 feet AGL my traffic system warned me of traffic ahead and above by 700 feet. I did not have the traffic in sight. I slowed my climb by throttling back and pitching forward. Unfortunately; my momentum was great enough that it did not immediately stop climbing; and I was able to level off at approximately 1;400 feet AGL. I lowered my left wing to begin a turn onto the crosswind and clear the direction of traffic and I saw the bonanza approximately 100 feet below and very close. I took evasive action and turned right to avoid them; and then continued my traffic pattern at 1;500 feet AGL.the decision of the other pilot to enter the pattern on a descending crosswind across the departure corridor; I feel; was a very poor one. The other pilot turned downwind at 1;500 feet and then continued to descend into the downwind; another poor decision. On a side note; I did try to talk to the pilot on the ground about what had happened; so perhaps we could both learn something from the event and he became very belligerent blaming me for going too fast; etc.this could have ended very badly for both parties involved; and I feel keeping a standard pattern entry is of the utmost importance. Unfortunately; not everyone agrees and still insists on doing it their own way at non-towered airports.
