Reset parameter selections via business rule

Hi - yes this is possible to do via a Dashboard Extender Rule that would be linked to a button or to execute on some other action. Below is some script that will reset a parameter to a blank value but you can substitute in any value you choose. Depending on where this runs from, you may need to change the DashboardExtenderFunctionType. For example, if wanting a parameter to reset after a button click then use args.LoadDashboardTaskInfo.Reason = LoadDashboardReasonType.ComponentSelectionChanged or if wanting parameter to reset whenever a dashboard is opened use DashboardExtenderFunctionType.LoadDashboard. Either way, the below script is what you need to reset or set a parameter value via a rule.

If args.FunctionName.XFEqualsIgnoreCase("ResetParams") Then
							
If args.LoadDashboardTaskInfo.Reason = LoadDashboardReasonType.ComponentSelectionChanged Then
Dim loadDashboardTaskResult As New XFLoadDashboardTaskResult()
											
								loadDashboardTaskResult.ChangeCustomSubstVarsInDashboard = True
								loadDashboardTaskResult.ModifiedCustomSubstVars.Add("ParameterName","")
														
	Return loadDashboardTaskResult
End If
End If
