InitializeVarianceBindings Method

Initializes variance bindings at start-up.

Syntax

Visual Basic

'Declaration
 
Protected Overridable Function InitializeVarianceBindings( _
   ByVal defaultBinding As VarianceBinding _
) As VarianceBinding

C#

protected virtual VarianceBinding InitializeVarianceBindings( 
   VarianceBinding defaultBinding
)

Parameters

defaultBinding

Default VarianceBinding pre-initialized with default binding member property values.

Return Value

An initialized VarianceBinding object; inheritors may replace the defaultBinding with their own custom subclass.

Remarks

If inheritors override this method to supply a custom subclass of VarianceBinding, then they must not access any WebScheduleInfo properties. Initialization may take place very early in the ASP.NET page lifecycle, and other WebSchedule controls may not be accessible. Premature access can cause the WebScheduleInfo control to prevent the data provider from connecting to it later on.

Inheritors subclassing a VarianceBinding can handle this method to have their subclass appear in the Properties window at design-time through the VarianceBindings property.

If you handle this method, overriding the RegisterDataBindings method becomes unnecessary. The data provider automatically registers VarianceBindings with it's data bindings collection during relevant operations.
