This project is read-only.


This field definition creates a TextBox control with an associated ellipsis {Button}. Clicking the button displays an Open File dialog and the TextBox is populated with the chosen filename.

By default FilePickerFieldDefinition will not be used. The easiest way to employ it is to register any String properties whose name ends with "Filename" to use file pickers:

FieldDefinitionRegistry.Register<String, FilePickerFieldDefinition>("*Filename");


public String Filter { get; set; }
Holds the file string to be applied to the OpenFile dialog when it is shown. Lets you customize the filetypes that the user can choose.

Controls Created:
  • ContentControl (ContainerControl)
    • Grid
      • TextBox (InputControl)
      • Button
