How to validate item text

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi Folks

I need to validate the CXTPReportRecordItem in report control in tree mode. If the text is no good I would like to display in a balloon tip in the edit control as well

When the user is typing text, I can display a balloon tip in OnEditChanging but my validation requires pinging a database to see if the entered text is allowed. So not a good place here to validate since every character typed would ping the database.

I cannot show a ballon tip in OnEditChanged, my guess is because OnEnKillFocus has occured.

Can anyone tell me the correct mechanism. I have caught XTP_NM_REPORT_VALUECHANGED but the edit control has gone.
So in short overridding 
1. OnChanging, no good, I cannot keep pinging the database.
2. OnChanged / OnValidateEdit, cannot get a balloon tip to display, due to KillFocus?
3. Catching XTP_NM_REPORT_VALUECHANGED still cannot display a balloon tip in the edit.

Anyone help please...
