I was unable to produce the “Bug” in a new application. Maybe the problem is in my own codes. Sorry

Yes, you can close this report. I have no other argument! All what i see that revision 10699 works great in all my applications but not the revison 10790 and higher.

Thank you and sorry again

Then even if it's not a direct problem in our side, maybe you could track the changes applied to that file and see why it creates a problem with your code.
Once you find that, maybe we can find a solution together.

The problem occurs only when the table is filtered and the event OnFilterRecord is assigned. In this case, OnFilterRecord is called many times (so many..), in any case much more than version 10699 for the same result.

Another thing: Click on then ScrollBar Down Arrow select immediately the last item of the drop down list.

See example uploaded: compile with the current version of JvDBLookup and compare the same project compiled with that of 10699.

This is fixed in Rev. 10954 by adding a property UseRecordCount that can be used to allow or forbid the control to use the RecordCount property of the lookup dataset.

ScrollBar down arrow click bug is also fixed.
