DataKey Constructor (IOrderedDictionary, String[])

Initializes a new instance of the DataKey class using the specified dictionary of key field values and array of field names.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public DataKey(
	IOrderedDictionary keyTable,
	string[] keyNames
)

Parameters

keyTable
Type: System.Collections.Specialized.IOrderedDictionary

The key field values.

keyNames
Type: System.String[]

An array of strings that contain the names of the key fields.

Use this constructor to create a new instance of the DataKey class using the specified dictionary of key field values and array of field names. The field values contained in the IOrderedDictionary object passed in for the keyTable parameter are used to populate the DataKey object. This constructor also allows you to specify a list of the key field names for the DataKey object in advance through the keyNames parameter. Because the field names are specified in advance, only the key field values are stored in view state when this constructor is used.
