NodeClick not rasied on server side when webdatatree is in ascx
posted

Hi 

I have an issue with new SR 11.1.20111.2064. In previous version all was working fine.

When webdatatree is in aspx event is raised properly, but if it is in ascx that is added dynamically to page from code in Page_Init event is not rasied at all.

I've found simillar issue in forum when webdatatree is in websplitter, but not sure if it is the same issue.

I can send you and example project if you want so you could try mine setup.

 

Cheers

    Hi,

    I've found simple workaround

     

    If IsPostBack AndAlso Request.Form("__EVENTARGUMENT").StartsWith("NodeClick:") Then

                Dim path As String = Request.Form("__EVENTARGUMENT").Replace("NodeClick:", "")

                path = path.Substring(0, path.IndexOf(":"))

                Dim node As Infragistics.Web.UI.NavigationControls.DataTreeNode = Nothing

     

                For Each nodeIndex As String In path.Split(".")

                    If node Is Nothing Then

                        node = lhsTree.Nodes(Integer.Parse(nodeIndex))

                    Else

                        node = node.Nodes(nodeIndex)

                    End If

                Next

     

                Dim eargs As New Infragistics.Web.UI.NavigationControls.DataTreeNodeEventArgs(node)

                lhsTree_NodeClick(sender, eargs)

            End If

    this should be executed in usercontrol page_load event.

    Still waiting for information about real issue
