How to Create a DB component with FIELD selector
Posted on 2001-09-16
Hi, I want to create a DB component where I select the Datasource. That works correctly, but when I want to select the FIELD (TFIELD) I get a list of ALL fields. I only want to have the fields from the source I've selected in the object inspector.
Anyone knows How?

Have a look in DBReg unit...
RegisterPropertyEditor(Typ
This means that TDataFieldProperty property editor is registered for all string properties called 'DataField' of all TComponent descendants.
I guess your component is a TComponent descendant <g>.
Is your property of type string?
Is it called 'DataField'?
IOW, does the declaration look similar to the following:
property DataField: string read GetDataField write SetDataField;
??
Please be more specific, and show us how the property is declared and any other info you think might be useful.
From the symptoms you describe it seems that your property is of type TField... but I don't want to guess for no good reason.

Yes the property is declared like that, I want to have a combobox with the fields from the table in the property editor.
Thanx, this method :
RegisterPropertyEditor(Typ
Is all I needed :)

It's strange that you needed it.
Anyway... You don't seem to be interested in a complete solution. Good luck.
