Multiple DBLookupComboBox tied to the same ListSource in XE4

[topcat01]

Hi List,

I have a single form with several DBLookupComboBox components tied to the same dataset same ListSource/ListField/KeyField. When I select a different value from any of the lists, all lists clear!

In Delphi 7, it was possible to select a different record of the dataset in each DBLookupComboBox, each of them storing and holding their own record, without issue. In Delphi XE4, this is no longer the case and as soon as I click on any of the DBLookupComboBox components and its dropdown list appears and before any selection is made, all of the other DBLookupComboBox components on the form are reset...

Any suggestions as to workaround this would be greatly appreciated as I am pulling out my hair

Thank you

Could it be that you are putting your DataSource (not listsource) in Insert Mode when the DBLookupComboBox drops down? That would explain why all of them are cleared, the New record has no values (null values) for the combobox to resolve against the listsource.

Thanks for the suggestion, I traced the problem, the dropdown was using an incorrect datasource during runtime (using different conditional during compile)

Thanks
