Web Forms :: Call A Javascript When Treeview Node Is Clicked?
Jan 6, 2011
I have a treeview on left side of a page. each node calls a different page on the right side . Right side page takes long time to load. so i want to let user know that its still loading. so when ever user clicks on the tree node for any page,i will to show him a image control with a text saying 'please wait.. its loading'. Sample code will be greate as i need to do this by end of day today.
after populating treeview and i want to traverse in all the node and want to attach javascript if the node has child node. how to do it in asp.net when work with treeview control.
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 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.
created treeview dyamically. I wanted to invoke a javascript confrim when a node is clicked . it should give him a popup saying are you sure you want to delete. if yes then call the file which is set in the navigate urlif user selects no, they nothing should happen.
TreeNode ActTNNode = new TreeNode("<span onclick=""javascript:confirm('Are you sure you want to delete);"">Delete</span> ");
I have a treenode and when the user selects the root, it does a post back and collapes everything. What I want is the Parent node to do nothing when clicked.
How can I set spacing between each node in treeview? the spacing is not the same for all the nodes. I want to manually add different spacing between leaf node and parent node.

[Code]....
as you can see, I want make space formatting in node, but after show it node to browser, all redundant spaces was removed. How I can deny removing spaces in treeview?
I have a C# page with 2 Panels, in the one at left is a treeview, and the other one is blank. What i intend to do is, avoid the framesets, and directly work with asp Panels. And when a node is clicked, target the blank panel.
I'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.
