I 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.

View 4 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 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 Repliesfor an application, I generate RichTextBoxes during runtime with the following code. The code generate a new node in Treeview under parent node "Notes".
Dim RichTextBoxCounter As Integer = TreeView_MainForm.Nodes_("NodeNotes").Nodes.Count
Dim NewNote As New RichTextBox
NewNote.Size = New System.Drawing.Size(845, 550)[code].....
Now, I want to show the RichTextBox if the associated child node is selected. I tried the code below, but it does not work.
If TreeView_MainForm.SelectedNode.Text = "Notes" Then
Dim NewNote As New RichTextBoxPrintCtrl
If TreeView_MainForm.SelectedNode.Parent IsNot Nothing Then[code]......
provide the code to display the RichTextBoxes after selecting the node.
I 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 am new to vb.net. I created a vb.net script to autogenerate a code. Now, after generating this code, what I want is to determine the validity of this code. for example, a code has been generated now and this code will be valid for 24 hours only.
Below is my script for the auto generation code
Dim randomvalue As New Random
Dim randomhold As Integer
Dim newcode As Long
For i As Integer = 0 To 9999
randomhold = randomvalue.Next(1, 9999)
newcode = randomhold & DateTime.Now.Minute & DateTime.Now.Year
Label3.Text = newcode
Next
The code generated will be sent via sms. If the code hasn't used within 24 hours, it will be invalid.
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:-

i'm worried about doing this since my changes will be overwritten when the dbml file is auto generated again (as they often are).i'm thinking of doing a partial class and writing out the same properties to annotate them, but worried that it will complain about duplicates, and the reason i can't even experiment brings me to the second part of my questions...
that, the expandable arrow on my dbml file listing is missing, right clicking and selecting "View Code" just displays an empty partial class as below.

View 2 RepliesI am trying to use a script mananger to use page methods to communicate between the server and client side of my page. I have added this code to the html

According to the General Naming Conventions the usage of CLR type names (e.g. String, Int16) should be preferred over the usage of language specific type names (string, short). I usually follow this advice. Resharper however seems to use the language specific type names when generating code (eg. when extracting methods or generating foreach loops) which is very annoying.
