Properties

Name	Description
DefaultBindingMode	Gets the default binding mode for the property.
EnableDataValidation	Gets a value indicating whether the property is interested in data validation.
IsReadOnly	Gets whether this instance is read-only and can't be modified.

DefaultBindingMode Property

Gets the default binding mode for the property.

public Avalonia.Data.BindingMode DefaultBindingMode { get; set; }

EnableDataValidation Property

Gets a value indicating whether the property is interested in data validation.

public Nullable<bool> EnableDataValidation { get; set; }

Remarks

Data validation is validation performed at the target of a binding, for example in a view model using the INotifyDataErrorInfo interface. Only certain properties on a control (such as a TextBox's Text property) will be interested in receiving data validation messages so this feature must be explicitly enabled by setting this flag.

IsReadOnly Property

Gets whether this instance is read-only and can't be modified.

public bool IsReadOnly { get; set; }
