View 1 RepliesI have an xml file with following structure:
<table name="tblcats">
<row>
<Id>3680</Id>
<Industry>Associations</Industry>
[code]....
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'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 problem with my treeview. I have two child nodes with different parents which contains a literal (*x). In this case (*1) (view image)
[Code]...
Is it possible to have more than one level of child nodes in a treeview? fore example can i have:
node1
-node2
--node3
---node4
right now it only lets me have
node1
-node2
node3
-node4
and also if it is possible how would i enable it?
I 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]

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.

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
[Code]...
The child nodes are there when first populated but when drives are changed or re loaded a second time, that is when they are missing, so how do I reset the nodes to show child nodes every time
[Code]...
I 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.
I have a treeview. The root nodes have images set at 30x30 - is there a way to add child nodes with NO image or a smaller image? I can do a blank image, but each child is spaced far apart! I would like the child nodes to be like there is no image... tight and close to each other.
View 13 Repliesi have a treeview which is databoud to a access dataabse, the database has 1 table, and the treeview shows everyname from column 2.
What im trying to achive is for the treeview to also display the names from column 5 and 6 as child nodes of the name from column 2. Been tinkering all morning to no luck, googles not finding much int he way of working examples, just lots of garbage.
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.)

For example 'b' is stored in a field so then 'a' will also be a radio button option, 'd' is stored in a database field so then the other radio button options will be 'a', 'b', 'c'....the radio button list will change depending on the value stored in the database field.
View 1 RepliesI'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 need to create a form with radio buttons, text boxes, labels, etc.. This information needs to be pulled from a database. For instance, I have a form that displays information that needs to be inputed to a database, based on what test is being done for a specific product. Each product requires different tests. So each product may or may not have the same information that needs to be inputed..
What I have done is made a database and filled a table with each product and what tests apply. I then call that database after the product has been selected for the tests. It will then fill an array for that products information for what texts boxes and labels need to be shown. I wanna take this further and have it create a form through code and align all the controls to specific spots so that it will look nice. For example I wouldn't wanna create a control and have it be cut out of the form, or have other controls overlapping others.

I have a treeview that is populated from a HDD folder collection. Its structure is similar to the following (however the structure is dynamic):
My Disk:
|
|--folder1(tag:folder)
| |--subfolder1(tag:folder)
[code]....
I call the sub as follows:
deleteNode(treeview1.Nodes(0).Nodes)
However, the above is not working properly. It deletes only some nodes and not all the targeted nodes.
OK, 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*

the values being assigned to my salary label are correct, but are not being updated until i select a new radio button. im not entirely sure how to get around this so that the value is updated as soon as i select the check box.here's when the program looks like:
