Web Forms :: Treeview: Add Leaf Node Items From Table?
Jan 27, 2011
I have populated a TreeView using data from a "documentCategory" table. This code works fine and shows the parent and child nodes correctly.I now want to show the relevant documents under each of the categories. The documents are stored in a "document" table and are related to the "documentCategory" table via a documentCatId field (ie, documentCategory.dcId = document.documentCatId).For example, I might have 2 documents under Employee->Manuals->Handbook->Asst Managers.How can I add these Leaf nodes? I have included my code below.
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.
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.
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.
At webform I have TreeView whith adding nodes from code:
[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.
iam having a treeview where the sample structure is like this. Cabinet under cabinet there is folder and under folder there are some documents.now i want that documents to move from one folder to another folder using drag and drop ...how can i perform this functionality.
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 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.
