IDataSourceFieldSchema Interface
Provides basic functionality for describing the structure of a data field at design time.
Assembly: System.Design (in System.Design.dll)
The IDataSourceFieldSchema type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | DataType | Gets the type of data stored in the field. |
![]() | Identity | Gets a value indicating whether the value of the field automatically increments for each new row. |
![]() | IsReadOnly | Gets a value indicating whether the field is editable. |
![]() | IsUnique | Gets a value indicating whether values in the field are required to be unique. |
![]() | Length | Gets a value indicting the size of data that can be stored in the field. |
![]() | Name | Gets the name of the field. |
![]() | Nullable | Gets a value indicating whether the field can accept nullptr values. |
![]() | Precision | Gets the maximum number of digits used to represent a numerical value in the field. |
![]() | PrimaryKey | Gets a value indicating whether the field is in the primary key. |
![]() | Scale | Gets the number of decimal places to which numerical values in the field are resolved. |
The IDataSourceFieldSchema interface allows a class to implement a set of properties that describe a field in a data source. The DataSetFieldSchema class implements the IDataSourceFieldSchema interface.
Classes that implement the IDataSourceFieldSchema are used by custom control designer components to provide lists of data source fields and properties for data-bound controls at design time.
