I trying to get what I think should be a simple thing. I have a checked treeview. I need to get the text of each checked node into a string. For the life of me I can't get it. I am trying to loop thru all the nodes and see if they are checked but I keep getting a "object reference not set to an instance of an object" but I don't know why.
Dim value As String
Dim node As TreeNode
Dim i As Long

my form contains a checked list box [data coming from the database] a combo box [bind to a database table product] and a listview [was previously a listbox]

I have a treeview control with check boxes. when I check the parent node, all the children check too. The problem is, I want the parent check box to automatically uncheck if one of the children is unchecked.
Private Sub TV_Communities_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles TV_Communities.Click
For i = 0 To TV_Communities.Nodes(0).Nodes.Count - 1
If Not TV_Communities.Nodes(0).Nodes.Item(i).Checked Then
TV_Communities.Nodes.Item(0).Parent.Checked =
False
End If
Next
End Sub

I am displaying all checked nodes from treeview1 like........
Private Function GetCheck(ByVal node As TreeNodeCollection) As ArrayList
Dim lN As New ArrayList
For Each n As TreeNode In node
If n.Checked Then
lN.Add(n)
Else
lN.AddRange(GetCheck(n.Nodes))
End If
Next
Return lN
End Function
It works properly. But If I prints checked nodes. Then again if I un-check any checked node from already checked nodes and now. If I print then I don't get the exact checked nodes. It still shows me previous output. What should I have to do for getting the exact checked nodes?

View 1 RepliesI have a treeview with nodes being represented as checkbox.
All works fine i.e when a parent nod is checked, its child and sub child should be checked as well but it won't check only the first subchilds and i am not able to find the solution, i have debugged it many time, but still not able to figure the solution.
I tried finding the solution on the web, but didn't got the proper solution. Below is the code which i am using in my form.

How can I Collect all the Checked Child Nodes Name From a TreeView Control Using VB.NET Windows Applications.
View 4 RepliesI'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.

project im working on for my course,the idea is a photo printing machine that loads up 4 images if usb stick is checked and a different 4 if memory card is checked. and then whatever image is selected appears in the big picturebox on the left [URL] i have 2 print size options set as radiobuttons, radiobutton 1 = 6x4, which costs 25cent per photo, radiobutton 2 = 8x10, and is 50cent per photo.i also have a textbox which will display the number of copies to be printed So here's my dilemma, when the print button is selected alongside one of the radiobuttons i want it to display a message saying something like this "you have selected (whatever the amount of copies)of this photo sized 6x4, or 8x10 depending on which radiobutton is selected, and i want it to display the total cost which is the number of copies multiplied by the rate for the print size selected, then an option saying "Do you wish to proceed" Yes or No.
I did something similar to this in class earlier in the year but cant remember it, it was an airline booking program with 3 types of payment cash, visa or mastercard,upon booking a message popped up saying there is a certain percentage discount for using visa or mastercard

I've got a checked listbox on my form which saves the checked items to a spot in my database on the .ItemCheck event.But there's a problem, when I begin checking items, I check the box and click off it, but it doesn't save. (This is if I've only chosen one item)
If I choose two or more items it will save, but unchecking them takes a lot of clicking around to figure it out.Is there a better event that I can use? I've tried the SelectedIndexChanged and that has the same result, there's a lot of clicking around in the checkboxes to end up with the desired selected items, and it does not allow a single item.
Does anyone know of a control such as a Checked List Box where each item can have a value against it.For example you have a list of fruits and in the listbox it displays Apple, Orange & Banana but the values for those items are A, O & B.

View 16 RepliesI am having trouble in allowing the user to select the row in the datagridview.
I managed to include the checkbox column in the datagridview but i do not know how to wrte the code such that when the user wants to update or edit the data in the checked row, he just have to check the affected rows checkbox, can be one or many, and then click on ok button, which will then lead him to the data updater form, allowing him to update the data.

I have a Data Repeater in a Windows Form, within the data repeater I have a label and either a radio button or combo box, the amount of radio buttons and the text for them is brought in from my database as is the label and combo box.
The label is a question and the radio buttons or combo box allows the user to answer the question.
What I want to do is get the checked status of the radio buttons so I can then reveal the next question if it is needed. e.g. only show question 2 if question 1 is answered No.
