Parameters

property PropertyInfo: Property from which attribute was derived.

Return Value

String
Expression based on source property.

Implements

IValueExpressionAttributeGetPropertyUpdateValue(PropertyInfo)

Remarks

The property update value is typically used to assign expression values to a modeled type. For example:

Copy

[TypeConvertedValueExpression("Form.maskedTextBoxMessageInterval.Text", typeof(string))]
public int MessageInterval { get; set; }

Would generate an expression of "Common.TypeConvertFromString(Form.maskedTextBoxMessageInterval.Text, typeof(int))" which would be executed as part of an overall expression that looked like Instance.MessageInterval = Common.TypeConvertFromString(Form.maskedTextBoxMessageInterval.Text, typeof(int)) when called from UpdateProperties(IEnumerablePropertyInfo, TypeRegistry).
