BindingContext.Item Property (Object)

Gets the BindingManagerBase that is associated with the specified data source.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public BindingManagerBase this[
	Object dataSource
] { get; }

Parameters

dataSource
Type: System.Object

The data source associated with a particular BindingManagerBase.

Property Value

Type: System.Windows.Forms.BindingManagerBase
A BindingManagerBase for the specified data source.

Use this overload if the BindingManagerBase you want does not require a navigation path. For example, if the BindingManagerBase manages a set of Binding objects that use an ArrayList or DataTable as the DataSource, no navigation path is required.

NoteNote:

The Item property will always return a BindingManagerBase, and never return null.

See the Binding class for a list of possible data sources and for information about creating bindings between controls and data sources.

The following code example returns three BindingManagerBase objects: one for a DataView, one for an ArrayList, and one for the DataSource of a Binding that belongs to a TextBox control.

private void ReturnBindingManagerBase()
{
   // Get the BindingManagerBase for a DataView. 
   BindingManagerBase bmCustomers = 
   this.BindingContext [myDataView];

   /* Get the BindingManagerBase for an ArrayList. */ 
   BindingManagerBase bmOrders = 
   this.BindingContext[myArrayList];

   // Get the BindingManagerBase for a TextBox control.
   BindingManagerBase baseArray = 
   this.BindingContext[textBox1.DataBindings[0].DataSource];
}
