How to populate DBLookupComboBox?

[Odlarhg 0]

Hi,

I need to populate a DBLookupComboBox with data from an SQL Server table. I don't have much experience with Delphi and although I created the DBLookupComboBox I can't populate it.

This is what I have done at the moment.

 

1. Create a TADOConnection to the database that contains the table
2. Create a TADOQuery
3. Create a TDataSource
4. Then create the DBLookupComboBox
5. In the properties of DBLookupComboBox
   1. I assigned the DataSource using the TDataSource that I créated
   2. I assigned the Id field in KeyField
   3. I assigned the Name field in ListField

 

With the above I understand that it should work, but as I said I do not have much experience with Delphi and I do not know what else I should configure so that the DBLookupComboBox can be populated with the data in the table.Could you help me?

Hi Odlarhg,

The component's Datasource/DataField are the main table.

You need to assign the ListSource/ListField/KeyField to the Table you are looking up.  The Key field should match the DataField.
