<para>There are a few cases in the .NET Framework object model where a property is purposely typed to be vague. For example, the <see cref="P:System.Windows.Forms.DataGridView.DataSource" /> property is typed as object. The reason for this is that this property can accept several types of input. Unfortunately, this provides no common place to add metadata to describe the characteristics of the property. Each DataSource property throughout the .NET Framework needs to have identical metadata for type converters, UI type editors, and other services that require metadata. The <see cref="T:System.ComponentModel.AttributeProviderAttribute" /> remedies this situation.</para>
|
||
<para>Once this attribute is placed on a property, the rules for obtaining attributes for the property descriptor's <see cref="P:System.ComponentModel.MemberDescriptor.Attributes" /> collection differ. Typically, the property descriptor gathers local attributes, and then merges these with attributes from the property type. In this case, the attributes are taken from the type returned from the <see cref="T:System.ComponentModel.AttributeProviderAttribute" />, not from the actual property type. This attribute is used on <see cref="P:System.Windows.Forms.DataGridView.DataSource" /> to point the <see cref="P:System.Windows.Forms.DataGridView.DataSource" /> object's specific type to <see cref="T:System.ComponentModel.IListSource" />, and the appropriate metadata is placed on <see cref="T:System.ComponentModel.IListSource" /> to enable data binding. In so doing, external parties can easily add metadata to all data sources.</para>
|
||
<para>Attributes obtained from a type declared in the <see cref="T:System.ComponentModel.AttributeProviderAttribute" /> have a priority in between the attributes of the property’s type and the attributes on the property. The following list, in priority order, shows the full set of available merged attributes:</para>
