[2008] Clear Checkboxes Automatically
Feb 17, 2009
This is a simple program, nothing crazy, just for a VB class. The program just a food ordering form. Each part of the order has a group box, with the type of sandwich, side, beverage, dessert you want selected via a combobox, and toppings selected with checkboxes (the code for the beverages is coded differently and giving me 0 problems, but at the instruction of the teacher who saw beverages giving conflicts with the way everything else was coded because radio buttons are used instead of checks).

What 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.

I have a pile of checkboxes on one particular form and would like to clear them all at the form load rather that saying chk1.Checked = False for all of them.
Here is the code I was trying to use but 'checked' is not a member of Systems.Windows.Forms.Controls.[code]....

I have a strange problem with a DataGridView I'm using which is bound to a table in VB.net
I've added a checkbox column to allow a user to tick a bunch of rows that I can then loop through and save off to a different table. All the checkboxes are enabled by default. So it's really a case of unchecking the rows which aren't required.
However, the DataGridView re-enables any checkbox that I click after I click on a checkbox in another row. So in effect, only one row can be unchecked at a time.
EDIT: I forgot to mention this is a Windows form, not an ASP.net application.

I have a form that opens another. I want the second form's checkbox to match the first form's after the second has loaded. I tried using MyForm2_Load, MyForm2_Activated and MyForm2_Shown but the checkbox checked state of the second form always changes the checkbox in first form. The code below works if I check the checkbox in either form, the other changes to match it. The problem occurs only when MyForm2 is first loaded. How can I get it to work the way I want it?

In my program, I can place an order for glasses.To do this, I have 4 text boxes:
StockNumber: [12345]
GlassOrPlastic: [Glass/Plastic]
ScratchCoating: [Yes/No]
UVFilter: [Yes/No]
Currently, it works fine... BUT I need to type in Glass or Plastic, I need to type Yes/No and same for each thing, wondering would checkboxes be more effecient or how would I do it?How do I even use checkboxes to get the same values...(If I type in Glass it adds �30 to the price, if I type in Plastic only �15 is added...)So if a Yes answer = �20 and a No = �10 How can I do that with checkboxes or whatever...My code for when I click the order button, myAddNew just adds my information in..
Private Sub OrderButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OrderButton.Click
Dim myValue As Integer ' Base value of frames
Dim myValue1 As Integer ' Glass or plastic value

I thought I could use this, to loop through all checkboxes in a frame:
For Each cb As CheckBox In Me.frameSearch.Controls
cb.enabled = False
Next
But it walks through once, then it comes with error:
Unable to cast object of type 'System.Windows.Forms.Label' to type 'System.Windows.Forms.CheckBox'.
There are indeed labels within 'frameSearch', but I thought that the "For Each cb as Checkbox" would loop only through all checkboxes..? Following does work, but it seems a bit of waste of CPU time, since it will loop through all controls!
For Each cb As Control In Me.frameSearch.Controls
If TypeOf (cb) Is CheckBox Then
cb.Enabled = False
End If
Next
How to do this more effectively?

I have to set a drop-down list with multi-select checkboxes. It seems to be a combination of combobox and list capacities (at least as I know them in VB6), so what's the best controller for these purposes in VS2008?

I'm working on a school project and need some help getting pointed in the right direction. The project is a lawn care application with 2 forms in which the user can select different services they want for their lawn. On Form1 I have 3 checkboxes the user can select: mowCheckBox , fertilizeCheckBox , and mulchCheckbox each with a different price. And nextButton to navigate user to Form2
On Form2 I have a listbox which shows the services the user selected, a totalLabel which will show the total dollar amount of the services, and a calcButton to calculate the total dollar amount.
The problem that I am having is being able to get the total dollar amount. If the user selects the mowCheckBox ($25) and the fertilizeCheckBox ($20) in Form1 I need the totalLabel in Form2 to show the total but cant figure out how to??
Public Class Form1
Private Sub nextButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles nextButton.Click

This may sound like a silly question, but I can't seem to find an answer.Is there any way to "Check" a ListViewItem when the user selects it via property? I'm sure I can figure out how to do it in code, but I thought there was a property of the ListView. I looked through the documentation, Google, and in the properties panel, but I can't seem to figure it out

I am creating a program in Visual Basic 2008 and I would like it so when I check a check box, the word that corresponds with the check box (in the code) will show up in the text box. So if i had one check box that said, Hello. Whenever that check box was clicked the word, Hello, would show up in the Text box. And then if I checked another check box, Bye, the word Bye would show up right below Hello. So it would look something like this.
Hello
Bye
But whenever I unchecked the check for hello, the word hello would go away and Bye would move to the top of the text box.Here is the code that I have so far. I can make the words appear in the text box but not at the same time in the list.
Public Class Form1
Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
If CheckBox1.Checked = True Then

I have a form that has many checkboxes located on a tab control with 3 tabs each tab has checkboxes on it.I have a button that when pressed selects all the checkboxes. That does work and it does execute all that were selected. However there are no checkmarks appearing at all. This worked before! It seems like the more checkboxes I added to the form the less they properly showed f they were checked or unchecked. Now none of them show unless I close the form and reopen it then all of the boxes are checked like they should be when the select all button is pressed.
