StateBag.Item Property (String)
Gets or sets the value of an item stored in the StateBag object.
Assembly: System.Web (in System.Web.dll)
Parameters
- key
-
Type:
System.String
The key for the item.
Using this member is the simplest way to save and retrieve view-state values for a control or a page.
If an item is not already stored in the StateBag object when you set this property, its key/value pair is added to the collection. If you set this property to null before the TrackViewState method is called on an item, it is removed from the StateBag object. Otherwise, when you set this property to null the key is saved to allow tracking of the item's view state.
The following code example demonstrates a property that saves its name and value as a key/value pair to the Control.ViewState property. The ViewState property is an instance of the StateBag class.
' Add property values to view state with set; ' retrieve them from view state with get. Public Property [Text]() As String Get Dim o As Object = ViewState("Text") If (IsNothing(o)) Then Return String.Empty Else Return CStr(o) End If End Get Set(ByVal value As String) ViewState("Text") = value End Set End Property
