| End-User Interface Features > Button Properties > Button Enabled State |
By default, True DataControl manages the enabled state of each button according to the current circumstances. For example, the Update button is enabled if a record has been modified.
The programmer can modify this default behavior by calling the EnableButton method.
It has two arguments: a button ID (ButtonEnum) and the enabled state, which can be one of the following three constant values:
|
tdbButtonEnabled = 0 |
Unconditionally enables the button. |
|
tdbButtonDisabled = 1 |
Unconditionally disables the button. |
|
tdbButtonEnabledDefault = 2 |
Resets previously set enabled set, so the button’s enabled state is maintained by the True DataControl default rules. |
