Add Xml A Node With A Bunch Of Children Nodes In .Net?
Nov 3, 2011
I need to modify a xml file (actually a .rdlc report file) and add some nodes which have a lot of children nodes (and those children nodes again have children nodes). Actually they are almost the same strucutre, like this one:
and it will add my specified NS. (like I said, XElement.Parse(string) won't add it) So now I can construct the correct node. For my second problem I still can't figure out: I can't navigate to the target node by using the element name since it won't search for correct NS.
How can i programmatically create a treeview consisting of several nodes and each node has several children.I want to read the nodes and children from a table and fill them accordingly, so how can i do this?
i need to check all child node when the parent node is checked and i had do research from the internet but it seem that i had a error which is Type 'MSComctlLib.Node' is not defined.do i need to import any reference? [code]
Is the following possible in one XPath expression (see sample below) Select all (span tags of class msg) AND all ((img tags that have a non-empty alt attribute) AND (are NOT located inside a span tag of class msg))
I'm trying to msgbox all the children nodes that exist in a treeview, however i was not able so far to msgbox except the first nodes in the first level of bracnching in the treeview, i want to go more in depth & msgbox all the children nodes.
Dim child As TreeNode For Each child In TreeGraph.Nodes("A").Nodes MsgBox(child.Text) Next child
I'm working on a drag-and-drop method to copy items from a listview control to a treeview. I've got the drag and drop working, but I'm hoping to limit the ability to drag items that create a child of a child. Ideally, if someone drags an item from the listview to the Treeview and the drop the listview item over a child, it would drop the dragged item to the parent.
I have been developing all sorts of programs and have found myself making a password safe program. While making this program I tried to use a listbox to display the passwords and such but have found that to be insecure and hard to manage and so I decided that adding a treeview to replace the listbox would probably be my best option. So in my program the user has an 'Add Entry' option and that loads a form where they enter the information they want put into the program and saved. So far I have it set up like this, They enter the user name in textbox 1, their password in textbox 2 and the website this information goes to in textbox 3. And then I have an 'Add Entry' button and when they press the button it adds the website to a node, and I'm trying to make the username a child of that node, How should I do this because I've been messing with this for about an hour and can't seem to figure anything out. Here is the code for the 'Add Entry' button if it helps:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Form3.TreeView1.Nodes.Add(TextBox3.Text) Me.Close() End Sub
I have a TreeView populated with some nodes, and some of those nodes have children. Is it possible that when the node, or child is selected that the entire node including the children be selected? I still want to deal only with the value of the root node, but for the UI I want the root + children to be selected.
I have a TreeView with a parent node and two children node. Each of the nodes contain a checkbox stored in a TreeViewItem. I want the two children node checkboxes to be set to IsChecked=true when the user checks the parent node and I want the two children node checkboxes to be IsChecked=false when the user unchecks the parent node.
So I have a TreeView and it has about 7 parent nodes that have 3-5 children each. All of these children nodes when click navigate to a URL. What I would like to do is have one parent node auto-expand based on the URL and the other parent nodes to collapse.
I have two XmlDocuments that both have a namespace attribute specified. Both documents have the same structure, but contain different data. I can't seem to get a specific node tree from one document added to the end of the same node tree in a second document. Here is an example of my two documents:
I certainly know this is wrong... I've tried serveral different approaches. This particular approach adds all <Item> nodes to the destination document, but it adds them to the very bottom of the document instead of after the last <Item>. how to add a specific node tree an XmlDocument to a specific position in another document? Again, there is a namespace involved and the <Item> nodes have nested nodes/elements under each one.
NOTE: The <Id> nodes have example data to show uniqueness only. I can never count on any kind of numbering. The order of each <Item> node is totally unimportant. I'm just assuming it will be easiest to add additional <Item> nodes after the last one in the destination document.
I want to create a treeview using this XML file. I have written following code
' Load a TreeView control from an XML file. Private Sub LoadTreeViewFromXmlFile(ByVal file_name As String, ByVal trv As TreeView) ' Load the XML document.
[code]....
where as I want table as parent element like this
->table ->Associations ->Fortune 100
so that If i click table node, all tree collapses or expands.
I Have a treeView Already populated (in vb.net) and would Like to move all the nodes or all the Tree for this matter, to a Root node that Contains it allI Have this:
Is there any libraries for .net that will do node based editing like Posers shader nodes. I would like to display a class and allow users to create custom formulas by dragging properties from 1 class to to seed the other class or other class properties. Regards See an example here link text
I need to find all the child nodes of a particular node in Infragistics tree view(WebNavigator). it is possible to get the parent() using the available property. But I need the childs. How can i access the childs of that particular node. I am using asp.net 2.0 with VB.Net. T
way to return a collection of treenodes which are children of a selected node? I can't find on MSDN a object of treenodes that is a collection of childnodes.
I have two treeviews, and I am writing code that will copy treenodes from one treeview to another treeview if it is selected. If a parent node is selected, I would also like to copy over all the children. If it is just a childnode, then I would like to copy just that.
Here is what I have so far.
Dim treeobj As TreeNode treeobj = TreeView2.Nodes.Add(TreeView1.SelectedNode.Text) If TreeView1.SelectedNode.Parent.Index.ToString Is System.DBNull.Value Then
treeView control which has been plaguing me for the last few days.
I'm not exactly sure what is causing this problem to arise, so I will just explain what my program is trying to do.
I am building an application which will have plugin support. I have created a Plugin interface, which is implemented by each plugin, as well as a host interface, which is implemented only by the host application.
Each plugin has an Action subroutine, and when finished, it is supposed to call the ExecutionComplete subroutine in the host interface.
Now, onto the problem. I have a treeView on the host form, which has several nodes in it. If I create a button on the form which displays a message box with treeView.nodes.count, it shows up fine, and everything works as expected. If I attempt to display the same messagebox from the ExecutionComplete subroutine, it also gives the correct number of nodes.
This is where things get a little weird. I have implemented a save feature into my program, so you can save and load data. For some weird reason, if you have loaded the data from a file, rather than adding each node manually, it now returns an empty node collection ONLY if I try to access it from ExecutionComplete. If I try to access the nodes from a button, it still returns the correct values!
What could it possibly be about the ExecutionComplete subroutine that makes it return a value any different than what is returned when the exact same code is placed in a button click event? And why does it only happen when I've loaded the data from a file? I just don't understand how loading it from a file is any different than them adding the nodes manually. The nodes are definitely being added, as I can see them, and the button click event can also see them. Also, ExecutionComplete is obviously able to read the contents of the treeView, because it works just fine if the user has set up the treeView manually.
Anybody here work with Nodes is a TreeView? I have a tree structure and need to enable editing to the selected Node. I have a String Variable where the enduser can Type in a new Folder name, click ok and the structure gets made. But I need the Node Name to follow suit. The only way I know how to enable editing is:
I was wondering how I would go about placing a check in the checkboxes for each child node of a parent node in a TreeView control, if I was to check the parent node.
For example: Parent 1Child 1 Child 2 Child 3
If I was to check "Parent 1" how would I be able to make that event place a checkbox beside all of the child nodes of "Parent 1"? (Child1, 2, and 3.)
[Code] my problem is if i search the class node with the name attribute of value "IT MAJEL 03", the xml reader reads through the first class which is "IT MAJEL 04" and read all of its child nodes(which i think is very awkward. why continue reading to its child nodes if the class name you're looking does not even match). is there another way to actually jump the reader of the xml node to the next xml node of the same level?
I mean if I search the class named "IT MAJEL 03", the reader should jump to the next same level element it does not match the query. It should skip reading the "IT Majel 04" child nodes. what I want to achieve here is I want to save nanoseconds of computing.
I've a treeview in my project form which look like this.
-Cover Page -Video1 -Podcast1[code].....
The user will be able to upload their pages to the respective pages nodes and I am suppose to make it in such a way that after the user uploaded the cover page which is showing at the PictureBox1 which I've use to display the image, and when he uploads the second page image at the PictureBox1, the Cover page image that he uploaded earlier on will not be overwrite.
I was told to create class and use array to store the contain in the respective nodes but I do not have any idea how to do it.
I'm all new to this treeview business. I have a fixed treeview, very simple and basic. Only two levels, parent and child nodes. I just need two things out of this treeview.
1) If parent is checked, check all child nodes.
2) If just one child node is unchecked, uncheck parent node.
That's it! I've been looking for this for 30 mins and I cant find it. Maybe because my vb.net is old, it doesnt seem to be the same as others =/ I'm using vb.net 2003.
i have a treeview which has a bunch of parent and child nodes preset at design time, there is 1 parent node tho which is called developer, that i want to add child nodes to at runtime.When the form first loads im trying to have it check a text file and for each line in the text file add the text/string from that as a child node tot he 'developer' parent node.
vb Dim reader As String = My.Computer.FileSystem.ReadAllText(Application.StartupPath() & "ConfigDevs.txt") Dim strs() As String = Split(reader, Environment.NewLine) For Each s As String In strs
[code]....
Thats what i have so far, how can i set it so 'Dim parentNode As TreeNode = ' points at the 'Developer' node?
