c# - Maintaining Scroll Position and Selected Control on Postback -

back web based issue.

when command issues postback server page refreshes (fine). page scrolls top , loses command selected. if it's relevent after postback depending on changes have happened controls made visible or made hidden. focus lost , current scroll resets if nil changed on page visibility wise. info inputted in text fields kept , radiobutton/checkbox selections. problem tabbing reset index 0 , pages scroll sent top of page.

i using .net 4.0

i have tried adding maintainscrollpositiononpostback="true" both on asp page , in web.config no avail. have tried , without ajax updatepanel using conditional updating triggering off when textboxes text changed or radiobuttons changed , postback still causes scroll , index loss.

any ides fantastic. ta!

first of all, maintainscrollpositiononpostback="true" has known bug in asp.net 2.0, see here.

also, right syntax maintainscrollpositiononpostback. (lowercase m)

i used maintainscrollpositiononpostback have many problems in ie, utilize asp.net ajax command toolkit updatepanel, solves problem (the page don't scroll top) , save bandwidth.

edit:

i think understand problem, it's mantain focus on element, can done using javascripts workarounds, se here.

hope helps.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
