Hi, I think that I am loosing my mind.

On a simple form I put one
- MyConnection and set it up and active = true
- MyTable set it up and active = true
- MyDataSource set it up
- tDbEdit set up to MyDatasource then select field Gestions
- tDbListBox set up to MyDatasource then select field Gestions
- tDbComboBox set up to MyDatasource then select field Gestions
- tDbGrid set up to MyDatasource

In the VCL
- tDbEdit field Gestions = Gest2011
- tDbListBox no display at all
- tDbComboBox field Gestions = Gest2011
- tDbGrid all fields and data is there

Run this very small application
- tDbEdit field Gestions = Gest2011
- tDbListBox no display at all
- tDbComboBox field Gestions = Gest2011 but the dropdown is empty
- tDbGrid all fields and data is there

I could move from record to record, every component is updated except the tDblistBox is allways empty.
For the tDbComboBox the dropdown is still empty

There is some bad day...

Everything you mentioned is working perfectly properly.

The DBCombobox and DBListBox always work like this from Delphi 1 up and is not specific to MyDAC..

You have to provide a List on the Component's Items property for the user to select from to make them useful.

Maybe the Devart teams might give your more assistant.

Hello,

Such behaviour of TDBComboBox and TDBListBox components is a designed behaviour of all Delphi versions, and it isn't connected with MyDAC. These components allow users to change the field value of the current record to one of a fixed set of choices. It means that you should add the values to the Items property of both components to have a choice of values.

Hi, you are both rigth.
This was just a bad day, a day where you should stay bed.

Thanks and if you could, delete this topic.
