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; }
/** @property */
public BindingManagerBase get_Item (Object dataSource)

JScript supports the use of indexed properties, but not the declaration of new ones.

Parameters

dataSource

The data source associated with a particular BindingManagerBase.

Property Value

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 a null reference (Nothing in Visual Basic).

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];
}
