View 3 RepliesI have a treeview which will be generated dynamically which need to be displayed on left side and when user clicks on a node it need to open a page on the right side of the same page. and each node has different aspx page. so whenever user selects a node the page details should be displayed on the right side .we can use an iframe on the page which will display the different pages clicked on the node.Is there any alternative i can use to display different pages based on the user selection on the right side without using iframe.
View 5 RepliesWhat I am acheiving is a simple treeview which will have a tree structure
dir1
-- xx
dir2
Simple stuff !. Here is the code
TreeNode tree1 = new TreeNode("dir1", "", "", "dir1", "");
tree.Nodes.Add(tree1);
TreeNode node = new TreeNode("xx", "xx");
tree1.ChildNodes.Add(node);
TreeNode tree2 = new TreeNode("dir2", "", "", "dir2", "");
tree.Nodes.Add(tree2);
Now I want to do is collapse all the tree and find a particular node e.g dir1xx
I have put the code
tree.CollapseAll();
tree.FindNode("dir1").Select(); <-- falls over
tree.FindNode("dir1").Expand();
tree.FindNode("dir1/xx").Select();
tree.FindNode("dir1/xx").Expand();
but it falls over on the 2nd line with object not set

View 3 RepliesI'm looking for a treeview with drop down list on each node. the treeview should be dynamicllay created on server side. Each node will have a drop down list and each item of the list will have a different color. When I create the tree on client side, I will have to select dropdown list accroding to a data table.
Also, on the client side, the user should be able to select each node and its leaf to group set the drop down list for one branch.
Is there any controller I can use rather than write my one tree?

Why does microsoft make objects in .NET with incomplete behavioural methods, then expect everyone to use a client side "language" to help complete the methods? I don't wanna have to use Javascript to keep focus on my leaf node in my TreeView after clicking it. I want a server side answer to my question, but if that's impossible I guess I can run ANOTHER javascript bandaid to do this, since I guess Microsoft doesn't have a solution. Oh and By the Way if your going to post an answer please remember I'm using WEBFORMS not WINFORMS. God help people who try to run my app (or any .net app) and don't have Javascript enabled on thier browsers. Does Microsoft own Javascript? Maybe since they rely so heavily on help from the client side to achieve behaviours, they ought to think about acquiring it.

View 4 RepliesI have an Update Panel on my web form. After click on the button inside panel, program generates treeview dynamically.
After postback, i initialize tree in Page Load.
The problem:
After clicking on the root node, node doesn't expand.
Question:
How it will be better to save and load expand (collapse) nodes state of my treeview?
Im using an asp.net treeview control and i managed to get code from these forums so that when i select a node no postback is done but i can access the selected node in my C# code behind pages by using javascript.
It works fine i can get the selected node by saying:
TreeNode t = TreeView1.SelectedNode;
and then displaying it to a label on an on click event of a button:
Label1.Text = t.Text;
But what i really need is to either display the node selected to a label (or textbox) or when a node is selected it needs to be highlighted so that the end user knows the option chosen is selected.

I am using asp.net treeview control. when ever user clicks any node,i want to perfrom some operations.
currently i am using the OnSelectedNodeChanged event.
but if user clicks on the same node which is already selected then OnSelectedNodeChanged is not getting called ( obviously it wont).

I am having problems with expanding the DIV's height when I click to expand the TreeView control.
What is happening is that I have a TreeView control inside an HTML DIV tag, but when I click the '+' sign to expand the TreeView nodes, the inner content of the node disapears behind that of the DIV tag. Instead, I am getting vertical scrollbars to roll down to view extra content. This is not what I want. What I want is for the DIV's height to expand to fit the TreeView's content.
i ve used the following code to avoid postback and selected node style for treeview by using this im able to avoid postback but im not able to set selected node style.
