    Calvin,

    Just a side comment: I wouldn't use a literal parameter to store the value of what button was pressed. The literal parameter is shared with all your users  and you will run into a problem where one user session overwrites the parameter value while another user session will eventually read the updated value but it doesn't reflect what the user should be seeing.

    A workaround would be to setup a runtime parameter that you then save to the dashboard parameter dictionary (i.e. args.LoadDashboardTaskInfo.CustomSubstVarsFromPriorRun in LoadDashboard section and args.SelectionChangedTaskInfo.CustomSubstVars in ComponentSelectionChanged section).

     

    Also that db_pdx said: have you tried "Tabs"

We get around the repetitive execution of BRs assigned to the "Load Dashboard Server Task (Once)"  by using the  args.LoadDashboardTaskInfo.Reason function. This function returns zero the first time the dashboard is launched and adds "1" on every subsequent refresh. So the following code lets the BR execute only on the initial DB load:

Public Function Initiate_EXD(ByVal si As SessionInfo, ByVal globals As BRGlobals, ByVal api As Object, ByVal args As DashboardExtenderArgs) As XFSelectionChangedTaskResult
			
   Try	
     'Run the Initiation code only on the initial launch of the dashboard
      If args.LoadDashboardTaskInfo.Reason > 0 Then GoTo GetOut

'Do stuff here for the first time the Dashboard is loaded

GetOut:
      Catch ex As Exception
       Throw ErrorHandler.LogWrite(si, New XFException(si, ex))
   End Try
End Function

Here are the steps:

Call the Set the Load Dashboard Server Task BR to run Once:

 

Call the function from Main:

 

At the top of the function, check to see if the Reason is more than zero. If it is, skip all the code and get out:
