  • Line Smoothing

    Drawing a signature on the screen with one's finger or mouse often results in choppy and jagged lines. Enable the optional line smoothing feature to help users provide clean-looking signatures. This feature will smooth out the lines and make the signatures look more natural.

  • Read-Only State

    Set the state of the UI for Blazor Signature component to read-only to cover scenarios when the user should be able to perform some limited interactions, such as opening the signature in a popup, but should be restricted from modifying the signature itself.

  • Signature Component Events

    To ensure smooth interaction, the UI for Blazor Signature component includes the following set of events:

    • OnBlur: fires when the Signature loses focus
    • OnChange: fires when the user presses Enter, or when the component loses focus
    • ValueChanged: fires when signature is fully drawn

    Check out the Blazor Signature events documentation

  • Signature Component Theming

    The Blazor Signature component supports four built-in themes, including Default (our own Telerik-infused styling), Material (based on the Material Design guidelines), Bootstrap and Fluent. Additionally, you can customize any of the ready-to-use themes with a few lines of CSS or create a new one to match your branding needs by using the Progress ThemeBuilder application.
