String. A descriptor of the action about to be applied to the DataStore. Action strings include:
The list is subject to change and additional actions may be added in the future. Case is not relevant for action values. |
Set the return code to affect the outcome of the event:
0 Continue processing (execute the action)
1 Prevent the action from being applied
For information on setting the return code in a particular environment, see “About return values for DataWindow events”.
Actions include navigating from page to page, inserting and deleting rows, retrieving and updating data. Typically the HTMLContextApplied event is used to call server-side methods for validating data that is about to be updated.
The SetHTMLAction method triggers the HTMLContextApplied event. If the HTMLContextApplied event returns 1, then the SetHTMLAction method returns -4 to indicate that the action was canceled.
