Dropdown Postback Not Working


thx Reply kedarrkulkar... Javascript function validateForm() { if (entry.pubdate.value == "") { alert("Please enter a publication date"); document.entry.pubdate.focus(); return false; } if (entry.slug.value == "") { alert("Please enter a slug"); document.entry.slug.focus(); return false; } You mean that the event will fire once a postback occurs, but that you have to insert a seperate submit field to invoke the postback?

What is the more appropriate adjectival form of Trump? I put a debug point in the selectedindexchanged event, but it doesnt go there at all. http://stackoverflow.com/questions/341080/asp-net-dropdownlist-autopostback-not-working-what-am-i-missing

I was using a switch statement and a combobox to show different pictures in a pictureviewer control.

However, you could probably still use an UpdatePanel even though you have such complex page logic. Wasn't aware that would negate the SelectedIndexChanged event. The time now is 07:18 AM.
