Editors

The Eremex Controls library includes multiple editors that provide advanced data editing capabilities. The editors allow you to display and edit data of different data types (numeric, Boolean, date-time, enumerations, etc.). They support the data validation mechanism to inform users about errors during data input.

You can embed the Eremex data editors in cells in container controls (DataGrid, TreeList, PropertyGrid, and ToolbarManager) to present and edit cell data. Although you can embed any custom control in cells, the use of Eremex data editors has many benefits from an application performance perspective.

Common Features

  • Text editors support masked input, which prevents users from entering invalid values.
  • Masks can be used to format cell text in container controls in display mode (when text editing is not active).
  • Supported mask types: Numeric and DateTime.
  • DateEditor uses a DateTime input mask by default.
  • SpinEditor uses a Numeric input mask by default.

• Data Validation
  • The built-in value validation mechanism allows you to show errors to users in all text editors and CheckEditor.
  • Text editors can display validation errors within edit boxes or below them.

  • Eremex application themes allow you to modify the appearance of the Eremex controls.
  • You can apply the Eremex application themes to a set of standard Avalonia UI Controls.
  • Eremex editors support the primary and secondary color variants for each theme. These color variants help you give a slightly different color accent to the editors by changing a single property.
