Adding The Same TreeNode To Two Nodes In A TreeView
When I attempt to run the following code:
protected void NavigationTreeView_TreeNodePopulate(object sender,
TreeNodeEventArgs e) {
TreeNode tn1 = new TreeNode("node1","node1");
TreeNode tn2 = new TreeNode("node2", "node2");
TreeNode newNode = new TreeNode("add me to both nodes", "add me to
both nodes");
e.Node.ChildNodes.Add(tn1);
e.Node.ChildNodes.Add(tn2);
tn1.ChildNodes.Add(newNode);
tn2.ChildNodes.Add(newNode);
}
It does not behave as expected. Instead of adding a copy of newNode to each
of the other two nodes, it adds to tn1 and then when it adds it to tn2 it
removes it from tn1, thus in the end only tn2 has the newNode and tn1 has no
children. How can I add the same node to two separate locations in a treeview?
I've got a bookstore I'm developing, and I wanted to list all the categories on the home page of the site. However, there are so many, that they now extend way below the screen, making the page look sloppy. I want, therefore, to limit the number of categories on the home page, to a few general categores, then clicking on one will reveal the subcatgories underneath.
I've been searching the net for a good example of how to read nodes from a XML file using ASP classic (VBScript), but I couldn't find any. I'll appreciate any explanation on how to handle the nodes, and how is it different from RecordSets. Code snippets of already made XML-reading scripts will be welcomed. I'm attending to use Microsoft's parser - XML DOM.
I am trying to port PRAX (PHP Record-oriented API for XML) to ASP and have run into a problem. With Microsoft's XML Parser, to get child nodes, the only way I have seen is by calling on obj.childNodes(1). I need to get a child node by name, not by number, since it could be in any order. Is there a way?
If not, I will have to write that part of the code differently by using an array. I don't want to do this because it would make the code more memory intensive and not as powerful as the PRAX implementation.
I have to read a XML file in ASP and save the values in a database. I can get this work, but I cannot read some nested nodes of the xml file. This is a part of the XML file: Code:
I am trying to update and append to an existing XML file. However I seem to be stuck. I am using ASP as my scripting language.
The form fields has the same value as the KEY attribute so all i have to do is loop through the submiting form for its fields and use the name to update the XML via the keys... Code:

This works perfectly on Windows IE 6.x and Mac IE. However, in order to be cross-platform compatible, I need to make this work on Mac Safari and Mozilla Firefox. Could someone point out how to fix this code to make it compatible with those aforementioned browsers?
I need to create a treeview on a database management .aspx site that when the parent is clicked, it expands to display the many associated records with it. Aka, it pulls info from not one, but two sql server tables. Further, these rows must be editable.
The problem isn't that the below doesn't work, it does. The problem is our sitemap is too big and I need to break it up. My objective is to output the categories only and when user clicks on a categorie the resulting proucts display similar to a tree view.
i want to have tree view navigation in my site.Anyone who has come across a good tool that is easy to code and maintain (and with good performance of course)? I don't mind invest to get a really good treeview utility.
Ones I have found so far are treeview.net and projectseven's. One thing important, it has to support unicode well. Most data are in chinese characters.
I have a asp.net treeview inside an updatepanel and I need to capture the right mouse click event. I have a context menu that will become visible on the right mouse click and I need to know what node was right clicked - can anyone give an example ?
I have been looking for a means to generate a recordset as a treeview in pure asp, collapsible/expandable by one field in the set as either a "+" or "-".
Can anyone point me in the right direction? Ideally, I'd like to not have to generate the entire recordset to deliver this tree view but have these expandable records generate with an "onclick" or something similar, but if it can't be help, I could live with it.
I have developed a ASP.NET application that uses the MS treeview web control. The application works fine on most machines but on a random few the control fails to display at all. All I get is an empty frame.
I have checked all the browser settings and they are exactly the same. Does anyone know what could be causing this?
This problem has had me pretty much at a standstill for nearly a day now.I have a TreeView in my Visual Web Developer 2005 Express Edition project. I have lashed up the OnSelectedIndexChanged event to my C# code behind.
There is one node I look for in that function. When that node is clicked on I do a Response.Write which contains Javascript. Every time that particular line executes I see the entire set of text in the TreeView increment one level in size.
Has anyone else seen a similar behavior in their TreeView controls? I have tried a number of "remedies" but to no avail.
Any suggestion for a COMPLETLY free treeview for ASP 3.0? We tried with one from obout.com. It seems to be free but you have to register it after 2 months.
