Hi.. i am downloading the trial again, but it was just last week that i downloaded and installed it....
here is my aspx code..
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" >
<Services>
<asp:ServiceReference Path="OrgService.asmx" />
</Services>
</asp:ScriptManager>
<div>
<ndiag:FlowChart ID="fc" runat="server" Height="550px" Width="750px" TreeExpandedScript="onTreeExpanded" AutoSizeDoc="RightAndDown" BoxStyle="Rectangle" BoxHandlesStyle="DashFrame" AutoActivateApplet="True" BoxSelectedScript="onTreeExpanded"/>
</div>
</form>
<script language="javascript" type="text/javascript">
var clickedParent;
function onTreeExpanded(parentNode)
{
if (parentNode.getOutgoingArrows().size() == 0)
{ alert(toString(parentNode.getText()));
clickedParent = parentNode;
setTimeout("callService()", 1);
}
else
{
var fcApplet = <%= fc.AppletElement %>;
layoutTree(fcApplet);
}
}
function callService()
{
OrgBrowser.OrgService.GetChildren(
toString(clickedParent.getText()),
onGotNames, onFailed);
}
function onGotNames(names)
{
var fcApplet = <%= fc.AppletElement %>;
var fc = fcApplet.getFlowChart();
fc.suspendRepaint();
var i;
for (i = 0; i < names.length; ++i)
{
var box = fc.createBox(0, 0, 25, 16);
box.setText(names[i]);
box.setExpandable(true);
box.setExpanded(false);
var link = fc.createArrow(clickedParent, box);
link.setArrowHead(MindFusion.Diagramming.ArrowHead.Triangle);
link.setArrowHeadSize(3);
link.setDynamic(true);
}
layoutTree(fcApplet);
fc.resizeToFitItems(5);
fc.resumeRepaint();
}
function onFailed(error)
{
var stackTrace = error.get_stackTrace();
var message = error.get_message();
var statusCode = error.get_statusCode();
var exceptionType = error.get_exceptionType();
var timedout = error.get_timedOut();
alert(
"Stack Trace: " + stackTrace + "\n" +
"Service Error: " + message + "\n" +
"Status Code: " + statusCode + "\n" +
"Exception Type: " + exceptionType + "\n" +
"Timedout: " + timedout);
}
function layoutTree(fcApplet)
{
var fc = fcApplet.getFlowChart();
var tl = fcApplet.getScriptHelper().createTreeLayout();
tl.setNodeDistance(12);
tl.setLevelDistance(8);
tl.arrange(fc);
}
</script>
</body>
and the modified service code...
Public Function GetChildren(ByVal parent As String) As String()
' imagine this is a database query
' create a few random names
INITSQL()
ADCom = Connection.InitCommand(adoconn, "GetBusinessUnits 1, '" & parent.ToString & "'")
ADReader = ADCom.ExecuteReader
Dim i As Integer = 0
Dim names(ADReader.RecordsAffected) As String
While ADReader.Read
names(i) = ADReader.Item(4).ToString
i += 1
End While
Disposeconnection()
Return names
End Function
if i do an alert on parentNode.getOutgoingArrows().size()
i also just get "object"
i'm thinking its something to do with the passing of the parameter form the applet to the js?
