Blazor Form Overview
Creating all sorts of forms is easy with the Telerik UI for Blazor Form component. As with other Blazor components, it gives you creative freedom in how you want to build your next application’s registration page or contact form while also keeping it simple – it can even be autogenerated from your data model!
-
Form Validation
The Form can be validated in its entirety through the built-in Blazor validation. This means you can provide validation rules directly on your model using attributes like Required, Range or MaxLength but any field the form contains can also be validated on its own. If you take this approach you wouldn’t even have to write any special logic.
More than that, Telerik UI for Blazor also provides 3 separate components to display validation errors. Read more about the ValidationSummary, ValidationMessage & ValidationTooltip.
-
Orientation and Layout
The Form can be fit anywhere on the page because it can be oriented both horizontally and vertically. It can render separate columns if you want it to. Configure it so it makes the most sense in your use case!
-
Field Configuration
If you don’t want to autogenerate the form from your data model, you can add a list of <FormItem>s. They can be customized in several ways like changing their appearance, data binding model values, adding hints and so on.
-
Data Binding
As mentioned, data can be bound to the Form component which will autogenerate all fields according your model, with different input elements used for different properties in the model (e.g. numbers will use a <NumericTextBox>.) This will both make sure set you the values of your model directly with what the user entered but also save you time. When the form is provided with a data model, it will automatically generate an input field for every property in your model, depending on its type!
-
Blazor Form Events
The Form supports 3 events – OnSubmit, OnValidSubmit and OnInvalidSubmit. You can guess when they are broadcast from their names:
- OnSubmit - on every submit
- OnValidSubmit – only on submits with valid input data
- OnInvalidSubmit – only on submits with invalid input data
-
Form Templates
The Telerik Blazor Form component can easily customize the label, form editor component and validation message of your app.
-
Theming
The Telerik Blazor Form component has several built-in themes such as Default (our own styling), Material (based on the Material Design guidelines) and Bootstrap (which looks like the Bootstrap styling to integrate better). You can easily customize any of out-of-the-box themes, style a specific component instance or create new theme to match your colors and branding by using the Telerik SASS ThemeBuilder application.
