Hello, I am using a diagram in javapplet mode. Below is my code:
aspx:
<body>
<script type="text/javascript">
function onObjectSelected(sender, args) {
var node = args.getNode();
if (sender.getSelection().size == 1) {
document.getElementById('hdObjectSelectedTag').value = String(node.getTag());
//tried both of the below to postback the updatepanel
__doPostBack('UpdatePanelMain', '');
//document.getElementById("<%= btnDummyObjectClicked.ClientID %>").click();
}
}
</script>
<form id="form1" runat="server">
<asp:ScriptManager runat="server" ID="scriptmanager"></asp:ScriptManager>
<div>
<asp:UpdatePanel ID="UpdatePanelMain" runat="server" UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnDummyObjectClicked" />
</Triggers>
<ContentTemplate>
<div>
<ndiag:DiagramView runat="server" ID="diagView" AutoScroll="true" Height="500px" Width="500px" ClientSideMode="JavaApplet"
NodeSelectedScript="onObjectSelected">
<Diagram AllowSelfLoops="false" AutoResize="RightAndDown"
RouteLinks="true" />
</ndiag:DiagramView>
<input type="button" id="btnDummyObjectClicked" runat="server" value="test"/>
<asp:HiddenField ID="hdObjectSelectedTag" runat="server" />
</div>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>
aspx.vb:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
diagView.Diagram.Factory.CreateShapeNode(10, 10, 25, 25)
End If
End Sub
Private Sub btnDummyObjectClicked_ServerClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDummyObjectClicked.ServerClick
'this gets called, yet the selected object loses its selection..also seems the entire page is posting back
'rather than the updatepanel
End Sub
I tried posting back the updatepanel 2 different ways, one way with forcing a button click and the other just explicitly calling dopostback on the updatepanel. Both ways seem to lose the selected object as well as postback the entire page rather than the updatepanel. I need to be able to postback the update panel and keep the node selected. Any help would be greatly appreciated.
Thanks,
jay
