Methods

OnReaderPropertyChanged(RadPropertyChangedEventArgs)

Occurs when the properties which are used for loading are changed.

protected override void OnReaderPropertyChanged(RadPropertyChangedEventArgs eventArgs)

Parameters:eventArgsRadPropertyChangedEventArgs

Event arguments.

Overrides: AsyncReaderBase.OnReaderPropertyChanged(RadPropertyChangedEventArgs)

ReadAsync()

Reads geospatial data using asynchronous mode.

public override int ReadAsync()

Returns:

int

Overrides: AsyncReaderBase.ReadAsync()

ReadAsync(object)

Reads geospatial data using asynchronous mode.

public override int ReadAsync(object userState)

Parameters:userStateobject

A user-defined object that is passed to the method invoked when the asynchronous operation completes.

Returns:

int

Overrides: AsyncReaderBase.ReadAsync(object)
