ReportViewer.SubmittingParameterValues Event

Visual Studio 2010

Occurs when report parameter values are submitted to the report server.

Namespace: Microsoft.Reporting.WebForms
Assembly: Microsoft.ReportViewer.WebForms (in microsoft.reportviewer.webforms.dll)

'Declaration
Public Event SubmittingParameterValues As ReportParametersEventHandler
'Usage
Dim instance As ReportViewer
Dim handler As ReportParametersEventHandler

AddHandler instance.SubmittingParameterValues, handler

/** @event */
public void add_SubmittingParameterValues (ReportParametersEventHandler value)

/** @event */
public void remove_SubmittingParameterValues (ReportParametersEventHandler value)

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

This event occurs when the user clicks the View Report button or when report parameters are automatically submitted due to dependencies between them. Information about this event is passed in a ReportParametersEventArgs object to the ReportParametersEventHandler delegate, which handles the event. This event only applies to remote processing mode.

Handle this event to read or modify the report parameters before they are submitted to the report server. For more information about handling events, see Consuming Events.

If you want to prevent parameters from being automatically submitted, subscribe to this event and use the following code. Note that this code does not prevent the ReportViewer control from initiating a postback.

Private Sub reportViewer1_SubmittingParameterValues(ByVal sender As Object, ByVal e As ReportParametersEventArgs)
    If e.AutoSubmit Then
        e.Cancel = True
    End If
End Sub
