Widget Button

Action column widget with a dedicated Button tab in the column metadata-editor.

When to Use It

• Custom actions at record level in list/edit.
• Callback triggers with user confirmation.
• Button rendering with custom template/icon.

Column Metadata Properties (Button tab)

• mc_button_action_type: button action type.
• mc_button_action: callback/function executed on click.
• mc_button_caption: button text.
• mc_button_tooltip: tooltip.
• mc_button_confirm_message: pre-execution confirmation.
• mc_button_executed_message: post-execution message.
• mc_button_image: button icon/image.
• mc_button_template: custom HTML template.
• mc_button_visibility_condition: conditional visibility rule.

Useful mc_props_bag

• style.editCss: layout control in the form.
• form.disabled: widget disabling at runtime.

Client/Server Effects

• Client: shows/hides button, confirms, invokes callback.
• Server: depends on the callback (may trigger API/business actions).

Operational Notes

• Always validate mc_button_visibility_condition to prevent actions on unauthorized records.
• Keep mc_button_action idempotent when possible.
