How can I Enable or disable Buttons runtime #52

How can I Enable or disable Buttons runtime using OnEnableNavBtn?

This code is not working. StyledDBNavigator1.Buttons[nbPost].EnabledNavBtn(False);

please write a sample line for this option.

As I already exaplained in last issue, look the example in the StyledComponentsDemo - form StyledDbNavigatorForm: EnableNavBtn is an event handler that you must link to your StyleDbNavigator. The event passes AEnabled param that is the default value for a specific ABtn (for example when the dataset is in EOF for ABtn.Index.nbLast button the value of AEnabled is false and the value of AEnabled for ABtn.Index.nbFirst is True. For example, If you want to disable the Delete button based to another function "UserCanDelete":

  if (ABtn.Index = TNavigateBtn.nbDelete) then
    AEnabled := UserCanDelete;

where UserCanDelete is your specific rule for enabling deletion of record.
