Is there a way to Select All, Unselect All a Multiselect Combo-box parameter?

I am trying to use a dashboard button to Select All and Unselect All values in a Multiselect Combo-box which I am passing to a Spreadsheet (TableView) business rule. I have tried to run a Data Extender rule from a button that clears the data using the code below: 

Dim selectionChangedTaskResult As New XFSelectionChangedTaskResult()
selectionChangedTaskResult.ModifiedCustomSubstVars.Add("lv_BusinessChannel", string.Empty)
selectionChangedTaskResult.ChangeCustomSubstVarsInDashboard = True
' Set the Return value
selectionChangedTaskResult.IsOK = True
Return selectionChangedTaskResult

    Not sure if this applies in your case, but a while back I switched from a combobox to a GridView with the Show Deselect All button enabled. The bound parm on the Grid View contains a delimited list of selections.

      I spoke too soon.  I can select items from the grid view, but when I move to the next tab and then go back to the Business Channel tabs the values are cleared. Basically I can Multiselect items on the component however the selected values are not being saved.

      I used something like this to collect the selections (using bound param): 

      Dim groupsString As String = args.NameValuePairs.XFGetValue("Groups", String.Empty)
      Dim groups As List(Of String) = StringHelper.SplitString(groupsString,",")

      Then I used these methods to manage state in a data table: BRApi.Utilities.GetSessionDataTable, BRApi.Utilities.SetSessionDataTable(si

      Wouldn't surprise me if there was another way to do this, but this worked for my use case.  Thanks Randy

      selectionChangedTaskResult.ShowMessageBox = True
      selectionChangedTaskResult.Message = "Clear Selection"
      selectionChangedTaskResult.ChangeCustomSubstVarsInDashboard = True
