Button
Button with a caption, icon, and click event.
WebButtonStandardVisual5 events
Quick start
Add Button1 in the Designer. Use the example in a page method.
Button1.caption = 'Save';
Button1.enabled = true;
Button1.onClick = async (sender) => {
sender.enabled = false;
try { Message('Saved'); }
finally { sender.enabled = true; }
};
// Button1.click();- Configure caption and icon in the Inspector.
- Link the action in Interaction → OnClick. Use enabled to prevent further activation during a task.
- click() activates the button from code. For a button with only a Lucide icon, use Icon.

Link methods in Interaction. How to use events.
OnClick
Standard event (Event).
Signature and example
import type { WebButton } from '@webrad/runtime';
// Copy this method into the page class and link it in Interaction.
class Example {
public async Button1Click(
sender: WebButton,
event: Event,
): Promise<void> {
console.log(sender.name, event.type);
}
}OnFocus
Standard event (Event).
Signature and example
import type { WebButton } from '@webrad/runtime';
// Copy this method into the page class and link it in Interaction.
class Example {
public async Button1Focus(

): Promise<void> {
console.log(sender.name, event.type);
}
}OnBlur
Standard event (Event).
