Fill PDF forms with Xamarin

This tutorial only applies to Xamarin.Android.

Interactive form filling for form fields such as text fields, checkboxes, radio buttons, dropdowns, signatures, etc. is supported by the PDFTron Android SDK.

Form Filling

Disable form filling

You can disable form field editing altogether by configuring ToolManager using the ToolManagerBuilder and disabling the FORM_FILL:

// Create a custom ToolManager with disabled form field creation
ToolManager.ToolMode[] toolModes = { ToolManager.ToolMode.FormFill };
var tmBuilder = ToolManagerBuilder.From()
    .DisableToolModes(toolModes);

// Add ToolManagerBuilder to your ViewerConfig
var config = new ViewerConfig.Builder()
    .FullscreenModeEnabled(true)
    .MultiTabEnabled(true)
    // ...
    .ToolManagerBuilder(tmBuilder)
    .Build();
