Overview
Documentation
The Form widget allows you to visually represent and edit data stored in an object. The widget binds each layout item to a specific field in an existing data object. To display a simple form, you can assign the required object to the formData option. With the Form widget, you can specify the location of labels against corresponding editors and number of columns used in the form layout. Optionally, the widget can determine the column count based on current form width (adaptive rendering).
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
Thank you!
