NoParametersOut Event

  • Article

The NoParametersOut event of the IParametersOutProvider interface occurs when the provider Web Part has no parameter values to pass to the other connected parts.

Remarks

A Web Part that implements the IParametersOutProvider interface should always raise either the ParametersOutReady or the NoParametersOut event. Some Web Parts may not behave properly if they do not receive this information. Raise the ParametersOutReady event to send the parameters. Raise the NoParametersOut event to indicate that there is no change in the parameters.

Example

The following code example shows an overridden PartCommunicationsMain method that fires the NoParametersOut event. This code example is part of a larger example provided for the IParametersOutProvider interface.
