I am working on a project and now I need to know how to have checkboxes on children nodes and not on parent nodes.
View 5 RepliesI need to help about treeview.I have a auto generated treeview with only SubNode checkboxes like this;Forexample; when I want to check B-SubNode-1 checkbox, the other node checkboxes (A-Node & B-Node) must be uncheck if it is checked. It might be check all SubNode checkboxes if their state under on a same Node.
View 2 RepliesWhat is the best way to clear all of a asp:TreeView checkboxes so that they are all unchecked? I've tried iterating through the treenodes and unchecking but this isn't working especially for child node checkboxes.
View 1 RepliesI have a 3 layer treeview and is using the code below. I am getting it to do the following,
1) If parent is checked, check all child nodes.
2 If just one child node is unchecked, uncheck parent node.
3) If all child nodes are checked, check parent node.
Code below only works for 2 layers. Would appreciate if you can guide me how to make it three. There are much information on treeview but most of them seems irrelevant =/ Will be great if you can show me a good guide on treeview control.

I've created a treeview that is going to represent a 'table of contents' for a Word template I use frequently and I need to add checkboxes to each node of the tree view.
Here is some of my code so far:
tvwSIGtemplate.Nodes.Add tvwSIGtemplate.Nodes.Item(2), tvwNext, , "3. Statment of the Issue and Solution"
tvwSIGtemplate.Nodes.Add tvwSIGtemplate.Nodes.Item(3), tvwChild, , "3.1 Issue Details"
tvwSIGtemplate.Nodes.Add tvwSIGtemplate.Nodes.Item(4), tvwNext, , "3.2 Solution Details"
What to add to these lines to simply display a checkbox next each line?

I have a tree view with checkboxes. When a user checks an item in the tree, all items below it in the tree should be checked automatically to match the parent. The same is true is a user unchecks an item. That's been reasonably easy to implement using the after check event:-

In WPF, I have a Uniform Grid and would like to be able to find the row and column based on the index of a child element.
I know there is a mathematical way of doing this and would rather not use a normal Grid.
If it helps, I can get the total number of rows and columns by using:
Math.Sqrt([*uniformgrid*].Children.Count)

I'm new to VB 2010 but have be using VB6 for many years.I'm currently stuck trying to store the state of open MDI childs at the moment the MDI parent is closed. Clicking the parent upper right close button appears to close all open MDI childs before running the parent 'Closing' or 'Disposed' events.I am therefore unable to detect which MDI childs are open and cannot restore them next time the application is run.Is there any other event for the MDI parent I can detect the start of the closing process before the children are closed?
View 2 RepliesI have 8 checkboxes and would like to click a button and clear all CheckBoxes. I know its possible, I just cant find any code anywhere for it.
Right now I am using TextBox1.Clear() to clear textboxes just needs to clear the checkboxes.
I'm doing an assignment for Uni and in my VB.NET form I have some checkboxes, I'm trying to loop through and clear them (I have a button which will clear the form). My problem is that there seems to be no property I can use to set the state of a checkbox when not explicitly telling VB which checkbox I want to use. for example, I can go
WineCheckBox.Checked = False
That will check the box, but I wand to DRY the code up a bit and not have to repeat this for each check box I have, this is what I was trying to do:
If TypeOf element Is CheckBox Then
element.Checked = False
End If
I've tried using element.CheckState and element.Checked and both times I get "Checked (or CheckState) is not a member of System.Windows.Forms.Control".
This is the whole block of code:
'clear the controls
For Each element As Control In Me.Controls
If TypeOf element Is TextBox Then

I have a group box which contains 40 checkboxes, when a checkbox is selected its content is added to a list and removed if already checked. Now I could write 40 functions one for each event (lots of code) each containing a add to the list function and a remove on uncheck, or I could use multiple handles (confusing multiple line declaration) is there another way? say my list of chkboxes had 100 checkboxes or more? can I for example use the container in some way?

I am attempting to complete an assignment for my Intro VB class and it is giving me a good bit of grief.
The assignment calls for at least 8 checkboxes with corresponding labels and one more label displaying the total amount due. I know that I am supposed to declare a form wide variable and then add/subtract from the variable within the even for the checkbox being checked.
I get the appropriate amounts to show in the corresponding labels but they wont add in the total due label.
I have a problem setting the checked state of checkboxes in a listview programmatically.
Background: I have a Windows Form Application which uses CheckedListBox�s. The names/labels for each CheckBox in the list are imported for a database. Also in the database is a field which defines whether the CheckBox should be Checked or Unchecked. The program works fine.
Problem: My requirement is to add a tooltip to each item in the list of checkboxes. I have read that the best/easiest way to do this is to use a ListView instead of the CheckedListBox. I have setup a ListView with CheckBoxes = True and View = Details. I have populated the ListView with the items from my database. The ListView now looks exactly like the CheckedListBox and the tooltips work fine.
My problem is that I can�t seem to find a way of setting the CheckBox�s to Checked programmatically. Is there a way to do this, or is there a better way of achieving what I am trying to do?
Ok so with my program i'm trying to create a save configuration I have it in my context menu so that I can click save configuration and what i want it to do is check to see what check boxes are checked and save those to a file (i.e. a notepad file or whatever works) that way I can save categories for customers or my own computer or whatever and than i'll just click load and choose the category I want and it will load the checkboxes that I want to install. I found a similar post but it's not really making sense to me. So i'm wondering what I need to do to make this work.
I'm also wondering how i'm going to load the configuration but I might have to wait on that one step at a time.

the problem with this code is that it only inserts the serial number of the LAST checked checkbox and the number of entries of it depends on the number of checked checkbox for example ... if I checked the rows with the serialnumber 123 and 55652341, first the row with the serial number 123 then second 55652341, only 55652341 appears in the database and it is entered twice(twice because two checkboxes are checked)
