C# - Formatting The Parent And Child Nodes Of A Treeview That Is Populated By A XML File?
May 24, 2010
I'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
the problem is actually in the subject. I have custom control that uses treeview. The control is added dynamically. Nodes for this treeview are populated on demand. Treeview nodes can be checked. I recreate this control on page load event, but still CheckedNodes is empty if checked nodes were added dynamically (added on demand).
when i check Treenode with Text='Velocity', all the three child nodes will get checked. I want only the count of child checked nodes. How can be it done.
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.
i added one treeview control in aspx page .All parent and child nodes are working perfect in this aspx page.
Now this same code i pasted in an ascx page and that ascx page i called through DNN website.That time parent node display is coming properly,but when i click on the parent node child nodes are not showing up?
I have a treeview and all nodes are check box, when user clicks on a button, how can I get all the checked child nodes belongs to specific parent? I wanna something better...
I am building treeview using asp.net 2.0/3.5 from master detail table.
ParentTable Value ---ChildTable Value ---GrandChildTable1 Node ---GrandChildTable1 Value ---GrandChildTable2 Node ---GrandChildTable1 Value
I have created something like this to populate node values. But I am not sure how to display GrandChildNode and values. Could you please let me know if there are any ideas?
protected void TreeView1_TreeNodePopulate(object sender, TreeNodeEventArgs e) { switch (e.Node.Depth) { case 0: GetParentTableValues(e.Node); break; case 1: GetChildTableValues(e.Node); break; case 2: } }
i have 2 combobox A & B.. the values in B is populated according to selected value in A,, my code works fine when i click combo A and select a item,, the values according to it get populated on combo B. i have written it on the change event...
But when i use tab to navigate and select the items in combo A and change on pressing keyboard down key...the items in combo B is not getting populated with new values.. existing values does not get changed,,, ie change event is not getting fired... how can i manage it in down/up key in keyboard when using tab,,,,
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?
I have an xml file like this.I wnat to display a gridview when i click on the EX_ACK_PEN i want to display a gridview with fields Tag,Value,Name.How can i get the childnode values .
I am trying to simulate the file system like explorer using a treeview. I would like to have the application in the server but is the starting root limited to where the application is? Is it possible to have a certain directory in the server to be the starting node? I would like to be able to set a starting node in the config.
Simple and blunt: my cascading dropdownlists clear when a postback occurs. Does anyone know a quick way around that?For more information, read on...
I have 5 dropdown lists that define a training class location and line of business: Site, Parent Client, Client, Program, Project I'm trying to build cascading dropdownlists that can work from any direction (i.e. select a site and all other lists are filtered by site...select a project and all other dropdown lists are filtered by project). I've built the SQL Select statement behind the lists that filters (accurately).
I understand that a treeview cannot expand/collapse without javascript. But is it possible to open the treeview in expanded form when javascript is disabled? Even if I cannot expand/collapse the nodes, at least I can click on the nodes that will display the data related to that node.
Similar to the treeview used in online auction sites, our treeview looks something like this: [URL], where clicking on a link will redirect me, and clicking on the "+" will expand or collapse the node. The only difference would be that ours is databound.
Another developer is working on this and he tells me that this is not possible without javascript. This webform in particular works almost entirely without javascript, and I'd like the treeview to also work partially.
I see that the data is there when I autogenerate. I can't seem to understand how to get the values from the nodes? Any reference anywhere on the ways to set the properties of databandings/TreeNodeBinding?
In my asp.net application I'm using TreeView control, and at some point I noticed that TreeView.Nodes property doesn't return all the nodes, so I'm curious how can I get ALL Nodes of TreeView control to iterate through them in foreach loop, any tricks, or I miss something?
I have a TreeView menu populated from a SiteMapDataSource. The TreeView defaults to all nodes expanded, but the normal client side expand/collapse behaviour for the nodes is not working. I get one Javascript error in my Firebug console, being:
