- Validation rules
/documentation/pages/Guides/Mobile and Web Components/Grid/Grid Fields/Grid Field Properties/Display Settings/Validation Rules.xml
The Validation rules property defines how your grid component will respond when a user inputs data into an editable field. As with the Field Properties list, these rules change depending on what type of control you are working with.
- Field Rule Field Events
/documentation/pages/Guides/Desktop/Design/Data/FieldRules/Field Rule Field Events.xml
When defining field rules for a table, there are two types of field rule events to which a script can be attached: Field events and Record events.
- Handling Errors
An important part of writing any program is handling potential errors properly. You should do the same when writing an Xbasic script, making sure it can recover from some common run-time errors (e.g., when a file is not found, the disk is full, or the table is opened exclusively by another session or user).
- Field Rule Evaluation
/documentation/pages/Desktop/Reference/Design/Data/FieldRules/Field Rule Evaluation.xml
Before a record is saved to the table with either the .ENTER_END() or .CHANGE_END() methods, the validation field rules for each field must be satisfied. If a field value violates any validation rule, a run-time error occurs. The field's validation rules are checked every time you assign a value to it.
- Error page 'Error' heading
/documentation/pages/Guides/Mobile and Web Components/Grid/The Detail View/Detail View Properties/Validation/errorpageerrorheading.xml
Specify column title for 'Error' column.
- Creating a Posting Field Rule
/documentation/pages/Guides/Desktop/Design/Data/FieldRules/Creating a Posting Field Rule.xml
During data entry, you can post values in the current field to matching records in a second table, thus adding to, subtracting from, or replacing the value in a second table.
- Error Functions
Functions for working with Xbasic errors.
- Error page 'Row' heading
/documentation/pages/Guides/Mobile and Web Components/Grid/The Detail View/Detail View Properties/Validation/errorpagerowheading.xml
Specify column title for 'Row number' column.
- Receive an Email Message
/documentation/pages/Guides/Desktop/Design/Email/Receive an Email Message.xml
The Receive an Email Message action allows the user to receive email using either the built-in Alpha Five email client, or the user's default email client (e.g. Eudora, Outlook etc.). This is an extremely versatile function that lets you send an email message that includes data from the current record.
- Extension::Curl Error Method
Return curl error message.
