)
'Usage
Dim instance As IParametersInConsumer
Dim sender As Object
Dim e As EventArgs

[ObsoleteAttribute("Use System.Web.UI.WebControls.WebParts.IWebPartParameters instead")]
void NoParametersIn(
Object sender,
EventArgs e
)
Parameters
sender
Type: System.ObjectA Web Part that implements the IParametersInProvider interface.
e
Type: System.EventArgsA System.EventArgs object.
Remarks
If a consumer Web Part that implements the IParametersInConsumer interface receives the NoParametersIn event, it should reuse its existing parameters.
Examples
The following code example shows the implementation of a NoParametersIn event handler. This code example is part of a larger example provided for the IParametersInConsumer interface.
' Step #9: Implement the NoParametersIn event handler.
' The connected provider part may call this method during its
' PartCommunicationMain phase
' to indicate there is no change in the parameter values. This allows
' the consumer part to display its cached data instead of potentially
' hitting a database again or recalculating values.
' <param name="sender">Provider Web Part</param>
' <param name="eventArgs">The Event Argumentsr</param>
