So it now looks like the code as follows, and I can move on from here: Changed what the label called 'Message' is displaying on the page under Sub Displa圜hildNode(byVal.) from Copied this example ALMOST EXACTLY ** AS WRITTEN EXCEPT put the script into the codebehind (putting it all here for anyone interested)Ģ. Got a VERY simple answer here, works like a charm! I can move on from here.ġ. Wasn't quite sure to do with what you provided, so kept looking. It's okay if any response is in C#, but vb.net would be great! For Each dr As DataRow In dt.Rows) or cause it to remain available for the math functions, or if necessary, create a new datatable that stores the node's value and the depth. Bind/append that information to the DataTable row (i.e. Find the depth for EVERY node in the tree on Page Load after the tree construct is present, without having to trigger a SelectedNodeChanged eventĢ. StrtLevel = ()īut I would like to know if there is a way to:ġ. I understand how to, in simple form, make this work when the event SelectedNodeChanged is triggered, i.e. I need to do some simple math to return a result based on the depth of any node in the treeview. I have created an asp.net TreeView bound to 2 tables in my database in the code behind, and coded in vb.net, that is working fine.Īll levels are expanded by design when the TreeView appears on Page Load. Specifically, it enables developers to configure html error pages to be displayed in place of a error stack DataBound TreeView - Determine Level/Depth of Each Node in TreeView > section enables configuration of what to do if/when an unhandled error occurs during the execution of a request. A full list of settings and comments can be found in usually located in \Windows\Microsoft.Net\Framework\v2.x\Config -> section enables configuration of the security authentication mode used by ASP.NET to identify an incoming user. Select all Open in new window Asp.Net Configuration option in Visual Studio. I know there's something going wrong with WebResource.axd but I don't know how to fix it. I've included a screenshot of the page when it doesn't work as well as the source code. But if I copy the working treeview page to the root of the converted web application, I get the display problems. On my development machine, the treeview control will work even if I use the web.config file from my converted web application. If I copy the treeview page to the root of the production website, I get the display problems I mentioned. In my production environment, the same is true: if I create a new website that is nested under the production website, the tree view control works just fine. If I create a brand new website from VS, the tree view control works fine. In FF, the page gives a WebForm_InitCallback is not defined error and clicking on the missing image text links gives TreeView_ToggleNode is not defined. In IE 7, there's a missing missing image icon and clicking on it gives a javascript "object expected" error. But the expand/collapse images don't appear. The control will display the text links and postback when a node is selected. I have an existing (VS 2005) ASP.NET 2.0 application that was converted from a 1.1 application earlier this year.
