View Replies View RelatedThis works perfectly on Windows IE 6.x and Mac IE.
However, in order to be cross-platform compatible, I need to make this work

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.

According to ms kb-article 183329 i am trying to populate a treeview object on a asp-page, with realtime data from a access database.
The database routine works fine and correctly returns the required records, the treeview object is not populated.
The syntax of the treeview1.nodes.add statement is correct (have them written to the browser to check) but still no entries in the object.
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 ?
View Replies View RelatedI 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.
View Replies View RelatedWe have a Datagrid and we are using third party tool treeview control. it's like we have to add treeview control in the datagrid dynamically, such that each cell will have a tree structure then we have to populate the data from the database according to the id.
View Replies View RelatedWhen 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?
We are using Microsoft's treeview.htc control to display a tree control in
our .NET application.
When displaying the tree, the browser returns the error:
Dynamic Link Library (DLL) initialization routine failed
pointing to the following line in treeview.htc:
if(oItem.filters.length>0)
in function blurFilter().
Does anyone have any ideas about this and how to resolve the error?
