External screens can also have changes that are bound to a secondary external screen.
In this use-case it is possible to programmatically prompt the user with the has changes dialog by adding an EventBeforeSelect on the corresponding Grid object.
In the EventBeforeSelect it is required to return a payload object with the setting "promptCursorChange" set to true. This will block the record selection and prompt the user with the Has Changes dialog.
Example:
| Code Block | ||||
|---|---|---|---|---|
| ||||
/**
* Method to execute before row selecting to display ExternalScreen hasChanges prompt
* @param grid
*/
export function onBeforeGridRowSelect(grid: akioma.swat.Grid) {
const payload:any = {};
const DocviewerExternalScreen = akioma.ExternalScreen.getExternalPopup('sDocViewerExternalWindow');
const hasChangesExternal:boolean = DocviewerExternalScreen.akioma.swat.Root.getFirstChildByType('businessEntity').hasChanges();
if(hasChangesExternal) {
payload.promptCursorChange = true;
}
return payload;
