VS 2008 - Loop Through Column Of CheckBoxes To See Checked Values
Sep 1, 2011
I'm trying to loop through a column of checkboxes to see how many checked values there are in that column. The user has to have 2; no more, no less than 2, otherwise an error should show up.
Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
Dim count As Integer = 0
Dim x As Integer = 0
For x = 1 To DataGridView1.RowCount - 1
[Code] ....
The error message still occurs when I have only 2 chosen in that column. I even tried this
If CBool(DataGridView1.Rows(x).Cells(7).Value = Checkstate.checked) Then

Suppose we got a form with some checkboxes. Each ckeckbox represents a method of the same class. Each method takes no arguments, returns no values. Is it possible using a delegate to loop through the checkboxes and run only the methods being checked?

I'm trying to count the number of checked checkboxes in column 5 of the table. I've tried several approaches, but none have worked so far.This is the code I've written so far. As you can see, I've managed to count the number of rows.
VB
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
dbProvider = "PROVIDER=Microsoft.Jet.OLEDB.4.0;"
dbSource = "Data Source = C:/Databases/database.mdb"
con.ConnectionString = dbProvider & dbSource

I have a datagridview with checkboxes in the first column and I want to do a loop on saving the serialnumber(s) when the users decides to check a number of checkboxes Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code]...
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)

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?

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

in my app I have to count the number of checkboxes have been checked to validate how many days were selected. 28 checkboxes in 2 groups of 14 to represent 2 pay periods. I tried counting the days by handling the CheckStateChanged or the CheckedChanged events of 14 checkboxes for each pay period, then if checked add 1 to payPeriod1 or 2. Either one of these works and counts the checked boes but when I try to reset my controls I get;

Example: That's 8 different combinations:
1, X, 1
1, X, X
1, 2, 1
1, 2, X
X, X, 1
X, X, X
X, X, 1
X, 2, X
Any way to get the different combinations depending on the Checked checkboxes into an ArrayList. One entry per possible combination (like the example above). Note this example is just for 3 games, I will have 13 games in my program so if you click all checkboxes thats 1,6M combinations. Is it really wise to have 1,6M entries in an Array? I also want to be able to set demands, like: delete all lines in the Array containing two X. Maybe an ArrayList isn't the way to go?

Alright I'm very sorry. This is a very Noobish question and I thought I could figure it out my self but I am haveing alot of trouble.Okay so I have 5 Checkboxes. When All them are checked I want Button1 to be enabled.And if any Checkboxes get unchecked after they where checked I want button1 to be disabled.
Now I think I got the code right. I just don't know what event to put it under. If checkbox1.checked = true and If checkbox2.checked = true and If checkbox3.checked = true and If checkbox4.checked = true and If checkbox5.checked = true then Button1.enabled end if

I wanted to see if I could have a list of six check boxes with names of a certain author that people have or have not read. When they are asked to check all that apply to them and then hit submit I want a label to display a message depending on the number of checks they made. So if they have 2 checks marked off then a message could say, "You do not read much of this authors books?" or 5 could say " You like this author, don't you?".

I have a dgv with a column type = DataGridViewAutoFilterCheckBoxColumn. I want to know if there's a way to I can get that entire column to become disabled (or Enabled = False) so it won't let the user click on the checkboxes. I tried looking in the "Bound Column Properties" but there isn't an option to disable the entire column.

I have a (checked) listview with values in the subitems. I am trying to make a simple sum of the checked values, but I can't seem to get it to work. The values returned aren't correct.
The idea is that each time I check or uncheck a row it re-calculates the values from subitems(2).
Here's what I was trying:
vb.net
For i = 0 to Listview1.CheckedItems.Count - 1 Label1.Text = CDec(Listview1.CheckedItems(i).Subitems(2).text) + cdec(Listview1.CheckedItems(i).Subitems(2).text)Next i
I have (text) values like 77.50, 115.60, etc.

I know my question reads a bit like that 'how much wood can a woodchuck chuck' line, excuse that... I have a repeater with checkboxes. There are numerous rows in this repeater - I never know how many - I want only one checkbox checked at any time. If the user changes the checked checkbox, any pre-existing checks are unchecked therefore maintaining a single checked checkbox.
I am using VB, but comfortable to port any C#. I want to use JQuery. I have been looking on Google, but only ever seem to find ALL checked, ALL unchecked systems.

I have a checked listbox that I've populated with a table that has three columns, Name, Address, Phone - and have done so successfully, but when i display the items in the listbox, i would like to retrieve additional values of the checked items other than the primary displayitem.[code]'we now have an array full of the Name column only, from our checked items 'i'd like to grab the other two as well (not to display in the listbox, but to use elsewhere as variables) 'and keep the checked listbox as a control in the above code, the fill_array variable is only populated with the items displayed in the checkedlistbox - my question is, can i keep the display item the same and pull the other two columns from the datasource, but only for the ones that make the checkeditems list?

I'm currently counting all the checked checkboxes in an asp.net gridview using:
$('#cphMain_gdvSalesOrder').delegate('input:checkbox', 'click', function() {
var count = $('#cphMain_gdvSalesOrder').find('input:checkbox:checked').length;
Whereas I need to count all the checkboxes that are checked apart from the one in the header.
