I am trying to add a TextBox or DropDownList to the nodes in a standard ASP.NET TreeView control so that I can take the user input when the node is selected and make use of the input text on postback in the code behind. The TreeView is configured to show CheckBoxes.If this is not possible, is there a way to render a text close to the node when it is selected for taking input? Or maybe have a Javascript prompt to take input when node is selected?

Periodically a rash of occurrences of the following error happen. I believe they're the result of hack attempts. Whether that's the case or not, my question is how can I handle the error? I want to avoid unhandled exceptions. The TreeView control is just
a standard .Net TreeView control, not a custom one. If you suggest a code solution, please code it in VB.Net as that's what I'm using.

View 2 RepliesI having an issue with the ASP.NET Treeview control. I create the treeview just fine but the nodes will not expand or collapse. I see there is a javascript error but it is for line 1 character 0 of the webpage, there is nothing at line 1 character 0.
I am using the ASP:Treeview control in conjunction with the Telerik controls, but I'm not sure if that is an issue.
I saw there was a similar question here but the answer is not pertinent to my site. Has anyone run into this issue before? I've tried searching Google and tried a number of proposed solutions but so far none have worked.

View 9 RepliesI have a simple Treeview on my web page. I am using ASP.Net 3.5. I have 2 parent nodes and then some child nodes for each parent when expanded. I want my 2 parent nodes to align up to the left. And I want the child nodes to be idented under the parent and all aligned to the left. Presently, it seems like everything is aligned in the center. It seems odd that there is not a horizontal alignment proprty. Or am I just not seeing it?

TreeView myTreeView = (TreeView)uxManageSlotsDisplayer.FindControl("uxTreeView");
myTreeView.Nodes[2].Selected = true;

I am trying to use a treeview control in my application. From the begining I had one parentnode and several childnodes for each parentnode. I wanted to be able to close an opened node when I click on a new one and I maneged that with OnTreeNodeExpanded method.
My problem is that I now need to expand my treeview so it will look something like this:
[code]....
What I want now is:
1. to be able to close an opened parentNode if i click on some other parentNode,
2. if i click on childNode i want to expand it so I can see grandchild,
3. if i click on another childNode for the same parentNode I want that the allready expanded childNode collapses and that the childNode I clicked on to expand.
I have a public folder on the server that contains recursively nested sub folders. In the various Leaf folders contains Images. I wanted to create a server side file browser that will display the Images to the user.I am using the ASP.NET TreeView Control.I create the tree nodes using PopulateOnDemand.
If the user click on a leaf directory I want the images in that folder to be displayed in a DataList Control.The problem is that when I click on a sub tree node (after I expanded it parent node)All the expanded sub tree disappears and only the parent node is showed with no + sign next to it !!( I have set the TreeView's PopulateNodesFromClient property to true )Here is the code :
<asp:TreeView ID="TreeView1" runat="server" AutoGenerateDataBindings="False"
onselectednodechanged="TreeView1_SelectedNodeChanged"
ontreenodepopulate="TreeView1_TreeNodePopulate">

How to do this programitically.
I want to populate treeview control parent and child nodes dynamically from the database table using sql server,asp.net and c# code,so that when user clicks the node in the treeview, it would take me to the selected aspx page.
I am writing our file to a web page, and have already figured out how to change the target of an iFrame when one of the Treeview's nodes is clicked so that the user is taken to the correct page of the file (mixture of javascript and treview properties).
What I can't figure out is how to adjust the treeview control when the user clicks on a link in the target page and is taken to a different file page. Absent any other action, the treeview control would still show the wrong node as being selected after the page is selected.
