Initializes a new instance of the DataKey class.

Overloads

DataKey(IOrderedDictionary)

Initializes a new instance of the DataKey class using the specified dictionary of key field values.
DataKey(IOrderedDictionary, String[])

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

DataKey(IOrderedDictionary)

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

public:
 DataKey(System::Collections::Specialized::IOrderedDictionary ^ keyTable);
public DataKey (System.Collections.Specialized.IOrderedDictionary keyTable);
new System.Web.UI.WebControls.DataKey : System.Collections.Specialized.IOrderedDictionary -> System.Web.UI.WebControls.DataKey
Public Sub New (keyTable As IOrderedDictionary)

Parameters

keyTable
IOrderedDictionary

An IOrderedDictionary that contains the key field values.

Remarks

Use this constructor to create a new instance of the DataKey class using the specified dictionary of key field values. The field values contained in the IOrderedDictionary object passed in for the keyTable parameter are used to populate the DataKey object.

Note

This version of the constructor does not allow you to specify a list of field names in advance for the DataKey object. Because the field names are not specified in advance, both the field names and values are stored in view state. To specify a list of field names in advance, use the DataKey(IOrderedDictionary, String[]) constructor.

DataKey(IOrderedDictionary, String[])

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

public:
 DataKey(System::Collections::Specialized::IOrderedDictionary ^ keyTable, cli::array <System::String ^> ^ keyNames);
public DataKey (System.Collections.Specialized.IOrderedDictionary keyTable, string[] keyNames);
new System.Web.UI.WebControls.DataKey : System.Collections.Specialized.IOrderedDictionary * string[] -> System.Web.UI.WebControls.DataKey
Public Sub New (keyTable As IOrderedDictionary, keyNames As String())

Parameters

keyTable
IOrderedDictionary

The key field values.

keyNames
String[]

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

Remarks

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.
