I have been having an issue when expanding a treeview, it looks fine when I load it, but when I click on a parent node it does expand, but also puts like 2 other parent nodes undernearth it. I am thinking it's because the treeview is saying that the parent nodes that have children have an index of 0, while everything else as there own index.
View 4 RepliesI m using Teeview control for displaying Family tree structure.its having around 500 members.
now, i would like to add search functionality inside a tree,after finding appropriate node,a whole tree should be expanded from that node only.
any one have idea? how can it possible?
i found one property called "ExpandDepth" but still its not proper for my requirements.
The following is a version of some code I'm having trouble running in IE version 6. It seems to work fine in IE 7, IE 8, FireFox, and Google Chrome. But in IE 6, when I expand and collapse nodes in the treeview, the SurroundingWrapper div resizes, but the message at the bottom stays glued in place (I'd prefer it stayed glued to the bottom of the div SurroundingWrapper). Can someone please tell my why this code falls apart in IE 6?

This is so frustrating...that such a simple feature should not be included in the design of this control. I am using the cssfriendly adapters and the rendered code is shown below.
I thought I might be able to use the adapter's treeview JS function ExpandCollapse__AspNetTreeView(this) since this is what is called when I click on the node that causes it to expand/contract. But that did not work.
I have seen other code posted but it seemed to imply the treeview was a table not a ul.
Does anyone know how to simply expand or collapse all nodes from a link button without doing the postback. Of course the postback works but what a waste to have to postback to do such a simple action.
Why doesn' t MS consider the users and developers when creating these controls and tools? Stupid!

I have bounded a treeview with an xml file. It bounded perfectly. you can have a view of my xml file.

MainMenu is the Parent node and Tracker, Reports ... are subodes. I want that if I click the node Tracker the all it's parent nodes(NBD, EOI, Proposal, Project, Sub Contract) should expand the remaining treevew remain same.
how's it possible to expand or collapse only one parent node at time. i am using Xmldatasource.
View 7 RepliesI'm very new to xml so I hope I'm not asking any silly question here. I'm currently working on populating a treeview from an XML file that is not hierarchically structured. In the xml file that I was given the child and parent nodes are defined within the attributes of the item element. How would I be able to utilize the attributes in order for the treeview to populate in the right hierarchical order. (Example Mary Jane should be a child node of Peter Smith). At present all names are under one another.root
<item parent_id="0" id="1"><content><name>Peter Smith</name></content></item>
<item parent_id="1" id="2"><content><name>Mary Jane</name></content></item>
<item parent_id="1" id="7"><content><name>Lucy Lu</name></content></item>
<item parent_id="2" id="3"><content><name>Informatics Team</name></content></item>
<item parent_id="3" id="4"><content><name>Sandy Chu</name></content></item>

How can I add a Treeview to the DropDownList for show child and parent record..
View 1 RepliesC#- bind treeview runtime using dataset and data table
simple example
I have a code that load hierarchy( nodes) into trew view.. by selecting different date, the hierarchy result from SP will show in the treeview..
the problem is even though I select a different date.. the result( node) of previous date is still showing in addition to the new hierarchy result...
it;s like the new result node is appended to existing node.. instead of refreshing the node and showing only the new result. How can I clear out the treeview nodes before adding new nodes from different date?

View 1 RepliesI have very strange Cascading Dropdownlist behavior. When I use one parent, one child - everything is fine, but one parent two children combination does not work well. Sometimes both children show right data; sometime first is fine and second is grey, or first is fine and second [Method error 500], or second is fine and first is wrong and so on.
Did somebody try to use parent two children combination?
I have two tables in SQL. The first defines the parent, and has a primary key column called ParentId. I also have a child table that has a primary key, and a foreign key as 'ParentId'. So the two tables form a one parent - to many children relationship.
The question is what is the most efficient way to pull the parent + child data C# code? The data has to be read into the following objects:
[Code]....
and use LINQ to merge all parents with children. This approach makes 2 trips to the db.
The third and final (also most inefficient) approach is to grab all parents, and while constructing each parent object, make a trip to the DB to grab all its children. This approach takes n+1 connections: 1 for all parents and n number of trips to get all children for each parent.
Any advise on how to do this easier? Granted i can't get away from using stored procedures, and I can't use LINQ2SQL or EF. Would you prefer Data Tables vs DataReaders and if so how to use either with approach 1 or 2?
I have a parent/child relationship that I'm currently pulling via the EF .include() method and displaying via two foreach loops in my view -- the first foreach loop is for the parents and the second is nested inside each parent and is for the children of that parent.
This has worked fine, but now I need to display information about each child that is not contained in my main child table. The table that contains this extra information only has a relationship to the main child table and thus there is no association between this table and the main parent table --- i.e. the .include() method can't pick this up. I've looked, found nothing and thus assume that I can't have two .include methods chained together. (even if I could, would this be efficient?)
I know I can perform a simple join and pull all of the child information with the parent records, but that would create issues with my paging because I want the page size determined by the number of parent records displayed. For some parents, there are only two children; other parents may have 10 children. So a simple join would create records where the parent information is duplicated and would throw off the paging.
Ideally I'd like to pull the parent information and pull the children information and connect the two when the view is populated, but I don't have a clue on how to do this efficiently (if that's even possible).
I want to remove parent control (which is span in this case) without deleting its children controls from container. how can I accomplish this in asp.net c#?
you can see the code here: http://pastebin.com/9NiriWXN
Note: I can easily find the "newsright" control and return its parent (which is span in this case)

I have a basic CMS which I'm adding to a site to display some downloads organised into groups. I have two tables, one for the groups and one for the downloads. I'm using a repeated to display the groups with another repeater inside to display the children. This works perfectly.
However some of my download groups may not have any downloads related to them and I'd like to handle this by filter the groups so that only those with a relate download record(s) are shown.
I'm trying to do this with the query which populates the top repeater based on some ideas I read but I must be going wrong with the syntax.
Here is what I'm using to try and only select downloads groups which have downloads linked to them by the download group ID.

Can anyone offer any thoughts on how I should construct the query to perform this?
I am using Tree view to display Categories & SubCategories under it. It's working fine. to create a Tree View I had used,
http://aspalliance.com/732.
Problem is that I want my TreeView to be expanded. How can one do that? Moreover, From another page when I click a Product, I want that in treeView that Category(under which Product falls), should be expanded & node(ie selected Product) should be highlighted.
how I can set a default view for a treeview. meaning I have a treeview created and has some data in it. when the page first loads it just shows the treeview. I need to actually display the very first node's data. So i have the treeview, with a parent node and 3 child nodes. I need to dynamically get the the parentnode and then get the first child node and display that data without clicking. I could just hard code the path in, but since this is still in development more nodes will be added and there for the order could change.
View 2 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
in my asp.net treeview if i click one parent node then it should be extended if i click again on that node it should be collapsed in treeview...
is any javascript availabe for this? or any code in selected node changed?
Should be easy but I cannot find a property which allows me to right align the nodes in a treeview.
I've tried adding text-align: right in a CSS declaration linked from NodeStyle > CssClass. Nothing.
