If DropDownList is empty, so
TAdvDBLookupComboBox.RefreshDropDownList;
doesn't work.
Otherwise it works
I'm not sure what you mean with this.
Please at least define "doesn't work". What exact error do you get?
I apologise. I'm an expert at asking vague questions.
The table for TAdvDBLookupComboBox is empty. Of course, DropDownList is also empty.
I will fill in some data in the table. I use TAdvDBLookupComboBox.RefreshDropDownList and DropDownList is still empty.
If DropDownList already contains some data, it is updated correctly.
No error is displayed.
I have retested this and I cannot reproduce this.
If a problem persists, please provide a sample source project with which we can reproduce this.
