Re: filter bool values

For those who want to know how I did it. Here my solution.

I added a changeListener through context click on the checkbox->programming->change event.

My Code to this event looks like the following:

public void check_Changed(object sender, XmlEventArgs e)

{

// Write your code here to change the main data source.

if (e.Operation.ToString() == "ValueChange")

{

String Artikelnummer = e.Site.SelectSingleNode("../my:Artikelnummer", NamespaceManager).Value;

XPathNavigator xnUArtikelnummer = this.DataSources[0].CreateNavigator().SelectSingleNode("/my:myFields/my:Updates", NamespaceManager);

foreach(XPathNavigator Node in xnUArtikelnummer.Select("//my:Update", NamespaceManager))

{

if (Artikelnummer == Node.SelectSingleNode("./my:uArtikelnummer", NamespaceManager).InnerXml)

{

Node.SelectSingleNode("./my:uCheck", NamespaceManager).InnerXml = e.NewValue;

}

Comment:

- look if the operation on the checkbox was a changeEvent

- compare Artikelnummer and uArtikelnummer

- if both are equal change the uCheck value to the current value of the checkbox

PS: Will it be faster if I just select all equal Artikelnummer and uArtikelnummer via XPath expression ? And only iterate trough them instead of all values?

Thanks a lot. That brought me to the right idea. I think I found a little shorter way, but with the same basic principle.

Hi,

You can achieve this using the following code. Write an on after change event for the check box.

[InfoPathEventHandler(MatchPath = "/my:myFields/my: Bestellungen/my: Bestellung/my: check", EventType = InfoPathEventType.OnAfterChange)]

public void field29_OnAfterChange(DataDOMEvent e)

{

if (e.IsUndoRedo)

{

return;

}

if (e.Site.text == "true")

{

string Artikelnummer = e.Site.parentNode.selectSingleNode("my: Artikelnummer").text;

IXMLDOMNodeList uCheckNodes = thisXDocument.DOM.selectNodes(string.Format("/my:myFields/my: Updates/my: Update [my: uArtikelnummer = '{0}']/my: uCheck", Artikelnummer));

foreach (IXMLDOMNode uCheckNode in uCheckNodes)

{

setNodeValue(uCheckNode, true);

}

private void setNodeValue(IXMLDOMNode node, object newValue)

{

if (node == null || newValue == null)

return;

string value = Convert.ToString(newValue, CultureInfo.InvariantCulture);

// The xsi:nil needs to be removed before we set the value.

if ((node.nodeType != DOMNodeType.NODE_ATTRIBUTE) && (value.Length != 0))

{

IXMLDOMElement elementNode = node as IXMLDOMElement;

if ((elementNode != null) && (elementNode.getAttribute("xsi:nil") != null))

{

elementNode.removeAttribute("xsi:nil");

}

// Force boolean values to lowercase.

if (newValue.GetType() == Type.GetType("System.Boolean"))

value = value.ToLower(cultureInfo);

// Setting the value would mark the document as dirty.

// Let's do that if the value has really changed.

if (String.Compare(node.text, value) != 0)

node.text = value;

}

filter bool values

Hello folks,

I have a repeating table with checkboxes and a repeating folder with values to update. When I select a checkbox, I want to set all check fields which have the same article number as the one which depend on the checkbox to the value of the selected checkbox. I tried to set a rule with a filter but an error appears, that I cannot set a filter to that field.

Is it not possible to filter boolean values ? How can I archive it ?

CAML:

<myFields>
<Bestellungen>
  <Bestellung> (repeating)
   <Artikelnummer>
   <Beschreibung>
   <Menge>
   <check> (checkbox value)
  </Bestellung>
</Bestellungen>

<Updates>
  <Update>
   <ID>
   <uCheck> (bool to set when checkbox is selected)
   <uArtikelnummer> (should match Artikelnummer)
  </Update>
</Updates>
</myFields>

Thanks in advance.

Regards Matthias.

PS: I hope my explanation is understandable.
