There is no way to store default values of controls directly in the executable, but you may want to save their contents to a file and recall them before displaying the panel, so that the panel is displayed with controls correctly filled.
To save all controls values in a panel in a step only you can use SavePanelState function to store values in a file. RecallPanelState retrieves values from the file and puts them on the panel in a single call.
If you are concerned with one control only in a panel, you may want to do the same programmatically on this single control, saving its contents in a file with INIfile instrument or in the registry with instructions found in the Programmer's toolbox.
