Is it possible to make multiple selections within a lists box. the scenario i have is that i have a data source within sharepoint structured as below.

Col 1 Col 2 Col 3
A 1 u
A 2 v
B 2 w
C 3 x
D 4 y
D 5 z

I have created the relevant filters so that a cascading list has been setup. If you select A in List (1) you then see in list (2) 1 + 2 then if you select 1 you see u in list (3). Easy !!!
But, i would like to be able to select multiple lines, ie A + C in list (1) so that list (2) returns 1 + 3 and so on. Is this possible. I looked at the possibility of using selection boxes but opened myself up to a whole world of pain. Any help gartefully received. Christian.

Hi

No InfoPath 2003 does not provide built-in support for Multi-select list
boxes, you would need setup it manually with a scrolling region, take a look
at the blog post by the InfoPath team for a sample

To have this list to be a cascading list of a previous dropdown selection

Here's is the code, try this:

Dim strategyNodes As IXMLDOMNodeList =
thisXDocument.DataObjects("LocalCommWKSLookups").DOM.selectNodes("//Strategies")
Dim numStrategies As Integer = strategyNodes.length
If numStrategies > 0 Then
For countStrategies As Integer = 0 To numStrategies - 1
If countStrategies <> 0 Then
thisXDocument.View.ExecuteAction("xCollection::insert", "Strategy_773")
Dim strategyNode As IXMLDOMNode =
strategyNodes.Item(countStrategies)
Dim NewStrategyNameNode As IXMLDOMNode = _

thisXDocument.DOM.selectNodes("my:myFields/my:Strategies/my:Strategy/my:StrategyName").Item(countStrategies)
NewStrategyNameNode.text =
strategyNode.selectSingleNode("StrategyName").text
Dim NewStrategyIDNode As IXMLDOMNode = _

thisXDocument.DOM.selectNodes("my:myFields/my:Strategies/my:Strategy/my:StrategyID").Item(countStrategies)
NewStrategyIDNode.text =
strategyNode.selectSingleNode("StrategyID").text
Next
End If

Hi CCarter,
We also sell a Smart Combo Box for a mere $9.95 that supports multi selection.
