Sets a value that indicates whether a field, page, or control can be edited through the UI.
Pages and group, part, and field controls
Yes (true on pages) if the field, page, or control can be edited; otherwise, No (false on pages). The default value is Yes.
For fields, use this property to make a field for display only.
For controls, if the Editable property for the container that contains this control is set to No, then that setting overrides what you enter here.
If a page has Editable set to No, then the controls on the page are not editable, even if the individual Editable properties are set to Yes.
The property setting is checked during validation. Validation occurs only if the field or control value is updated through the UI, for example, if a value is updated on a page or if a field is updated in a table. If a field is updated through application code, then the Editable property is not validated.
|When using CurrPage.Editable, the Editable property also reflects the page mode that the page was opened in. This applies to Edit, Create, and Delete modes, but not to View mode. If the page is editable, then CurrPage.Editable will return false.|
On pages, you use the Editable property for group, part, field, and action controls. You can make them editable or non-editable either statically by setting the property to true or false, or dynamically by using a Boolean variable or a Boolean field on the page. The Boolean field on the page can be either a true/false Boolean or a Boolean expression, such as “Credit Limit > Sales YTD”.
Example: Dynamic Property Change Using a Boolean Field
To make the Credit Limit (LCY) field on customer cards non-editable unless line discounts are allowed, follow these steps:
Open page 21, Customer Card, with Page Designer.
View the properties of field 22, Credit Limit (LCY).
For the Visible property, enter “Allow Line Disc.” in the Value field.
The Allow Line Disc. field is a Boolean field on page 21, Customer Card.
Save the changes on page 21.
Now, when a user selects the Allow Line Disc. check box on a customer card, the Credit Limit (LCY) field is editable. Otherwise, the field is non-editable.
