Checking Treeview Nodes - If Parent Is Checked Check All Child Nodes
Aug 31, 2011I'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.

VS 2008 Add Child Nodes To Child Nodes?
Aug 10, 2009OK, so I have the code to add a Child Node to a selected node in ta TreeView. The thing is, even if I select a child node to "add" to, it adds the new node to the parent of the selected child node.
I know why it does that: TreeView1.Nodes(TreeView1.SelectedNode.Index).Nodes.Add() adds to the first node. So how do I progamatically add to the child node I have selected, not it's parent node. I can't figure out the logic on how to accomplish this.
NOTE: There can be an infinite amount of child nodes.
UPDATE: I just found out that if I have a child node selected, TreeView1.SelectedNode.Index returns -1 since there is nothing selected in that first level. I'd have to use TreeView1.Nodes(0).SelectedNode.Index to get the proper index for the ChildNode. *sigh*

Add Child Nodes To Treeview Dynamically
Aug 24, 2011I have the following code which checks for the value of the 'cc_supplier_status' column for each of the rows in my table. If the state is 0, I need a child node to be added to a node named 'Inactive Suppliers' in my tree view (tvw_Supplier) with it's text being the value of the 'cc_ supplier_ name' value for the same row.If the state is 1, a child node is to be added to a node named 'Active Suppliers'.If the state is 2, a child node is to be added to a node named 'Pending Suppliers'.The code I have now just filters out the status value for each row, and performs a select case on it. I need to know how I'd add a new child node to the parent nodes mentioned above.[code]

VS 2010 : XML Child Nodes 'loops'?
Jun 1, 2011I have a bunch of XML's that need to be put into an SQL database. One XML represents all orders for a certain department of a store. The problem (for me) is that in one XML there can be (and are) multiple orders (called distributions in my case.) The XML looks as follows (truncated):
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<order><process_id>322867</process_id>
<key1>RET</key1>
<key2>40_134985</key2>
[code]....
So in this example I have two 'distributions'. Now I can get all data out of the XML fine, which I do like this:
get xml data
awsFeed = XDocument.Load(fileName)
Dim orders = From order In awsFeed...<order> _
[code]....
However, in this case my SQL input would have to result in 2 entries, because there are 2 orders. Both entries would have the same data, except for different entries. I know how to post to SQL, that's not the problem. My real problem is, how do I 'loop' it through the XML. I think i'm looking for something like:For each 'distribution' in orders -> put into array.Or something like that. After that I could query the array and put it in the database.

adapted from Major treeview/list view head ache I managed to make the treeview display the folder and the sub folders... but it isn't very hierarchial. Check attached pictures. Image1 shows how it is and image2 shows how I want it to be. Can anyone tell me how to get it to look like image 2?...Image2 was made in Windows Explorer. Image1 is a screenshot of the runing program that I am trying to make. I have been googling around but no luck so far. Practically I think what I shoul be asking is how to create child nodes of subfolders. The program is going to copy whatever the user checks in the treeview into another folder chosen by the user. I am using Visual Basic 2008 Express.
Asp.net - Adding New Child Nodes To XML On Each Function Call?
May 12, 2012I have an XML file and I have a function to which this XML is passed as string. I have loaded this string in Xmldocument and I need to insert few children nodes under one node. This function returns the modified XML string. I want that whenever this function is called, new child nodes are added, currently, It adds child nodes once.Do I need to overwrite the XML file ? If so, How can I replace the node with new node ( with new child nodes added) so that It has child nodes added before the function is called again ?

Collecting Arrays Of Parent And Child Nodes
Jul 17, 2010Most of my treelist code is working ok, however I would like to produce two arrays of string, one which contains all the parent nodes in a Treeview, and the other with all the child nodes.

VS 2008 : Adding Parent And Child Nodes To TreeView?
Oct 31, 2010I am not sure I am getting the concept of referencing nodes in a treeview. When I hard-code nodes like:
tnParentNode = New TreeNode("ABC")
tvReports.Nodes.Add(tnParentNode)
tnParentNode = New TreeNode("Some Other Company")
[code]....
I get two parent nodes and one child off Some Other Company. However, when I pull information from a couple of tables to set up the parent and then the child nodes, I only get the parent nodes.So I pull the main parent nodes from one table and the child nodes from another table.This code pulls the parent nodes without any problem:
strSQLText = "SELECT lID, sCatName FROM Category ORDER BY iSortOrder DESC"
reader = GetReader(strSQLText)
While reader.Read
[code]....
But this does not add the child nodes. I am assuming it is because of the first line in the above reader.read while loop. I must not be referencing the proper parent node but I am not sure how to do it.
