In this blog post, you will learn the procedure to create a dynamic form builder in Blazor with the EditForm class and data annotation validation. You will also learn the steps to generate form components based on data type and display validation messages using data annotation. Every step is explained with a working sample and simple code examples.

Dynamic form builder

Form input and its validation are very important for any application. In this blog, we will display employee details through a form design. This application will have a minimum of 10 user input entries in a form. We are going to create a form using data model classes and data annotation.

We will create components dynamically and render them in the edit form:

• For string data type: TextBox component.
• For string with multiline data type: TextBox with multiline (text area) component.
• For number data type (integer, decimal, etc.): NumericTextBox component.
• For DateTime data type: DatePicker component.

Let’s see the steps to create a dynamic form builder based on the data model class and implement data validation using Syncfusion Blazor form components.
