Check Count Of All Checkboxes In Datagridview?
Jun 4, 2011
i am currently having problems with Datagridview, for example when i select the first checkbox, second checkbox onwards.
I would like to update the textbox on my form to display '2' records selected. But there is one problem i faced is that when i deselect the checkbox, it does not update. It still display '2' record selected. What event handler should i use to get it to work?
Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgvAssignGridView.CellContentClick

As you all know, If the dataBase requires a numerical value then an error will occur when the user tries to insert the incorrect data type. With the code below after the user types in a value beside an int value type then it will go into an Loop through more than what is needed. How can I apply the same logic but allow the program not to check the 60 rows (I set the row size to 60). I want to break out of it if there are blanks ONLY if a row is blank and not for a black cell, because if the user leaves one cell blank then it would loop through the 'for each' for how many rows that they is. Initially there are 60 rows.
MIS
For Each item As DataGridViewRow In dgvLaser.Rows
If IsNumeric(item.Cells(3)) Then
Exit For
Else
MessageBox.Show("Check Record Count. Numerical values only..!")
End If
Next

This is my problem.I have a field set up in MS Access to Boolean YES/NO, this field is populated when the user check a checkbox on a windows form. If the user check a checkbox, the value is written as checked in the data field (MS Access).The problem is when I search for the user information, I need the information from the Data base to populate(return) to the windows form. Example: If I enter a users phone number and the user data is present, the form gets populated with the information the user previously entered which was store in the database.Example: If the user selected checkbox1 and submits the form. When I search for the user info, the check box should check(populate) because the user had checked it on submit.Here is what I have done:

Example: If the use select checkbox1 and submits the form. When I search the form, I need to make that particular check box check.

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'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.

I have a piece of code for a program where when a specific checkbox is checkedunchecked (In this case "Allyellow") it checksunchecks any checkboxes within a group of 14 with a lightyellow backcolor.
While the piece of code below does this fine it seems to me to be very clunky and it must be possible to streamline it.

Using .Net, I need to generate a response based on only the checkboxes on my form that have had there states changed. So how do I know if the check box has changed from its previous value before submission. I can't use the onchange event because the user may check multiple boxes before submitting.

I have several checkboxes in a groupbox on a vb 2008 express userform. I would like to check the checked status of each when clicking a command button and then write the checkboxes caption to be used in an email or print out. I've tried several methods and always end up with the same error "Invalid Cast Exception". I have read the help on msdn and still do not understand how to make it work. Here is the code I've been trying
Dim chk As CheckBox
Dim sb As New System.Text.StringBuilder
Dim names As String
For Each chk In gbInterior.Controls
[code]....
I have also tried the code below but cannot figure out how to check the status and print the checkbox caption.
Dim ctl As Control
For Each ctl In gbInterior.Controls
If TypeOf ctl Is CheckBox Then

I'm working on a project where I've loaded a database into a DGV. I also have an additional unbound checkbox column for the users to select entries with. I have code in place to read the selected rows and save them into a CSV string, which is then saved in the usersettings. All this works fine.
PROBLEM AREA:
I'm trying to reverse this effect so that when the DGV loads, the checkboxes that the user selected previously are checked (and the others left unchecked). I've debugged this extensively, and using watches have confirmed that all the values in the loops are right, and the conditionals are all kicking correctly, but it seems the code I'm using to actually check the boxes doesn't work. I've searched dozens of web pages, msdn white papers, and forums, but no suggestions will check the darned box. Below is some example code.[CODE...]
In debugging, it seems the value for the Cells IS changed, but the checkbox never gets selected. The try/catch was just to pick any error messages (but there are none with this code). What am I doing wrong here?

I have a datagridview that is showing Yes and No in 2 checkbox cells. (Logically I should have just one checkbox but it is a legacy program (from Excel VBA)). So what I want to do is if the user clicks one checkbox cell to make the value True then the other checkbox in the row needs to be set to False. I have googled and searched the Forums here for an answer for this but found nothing really specific. The envisaged problem here of course would be that the events are mutual so they should not keep firing continuously in a "loop" when one or the other is changed - that might be the really difficult bit.

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.

.Net 3.5
I have 2 columns in a datagridview bound to datasource. When the user checks off one checkbox, i want to check some business logic after which I set the 2nd check box in the same row as checked as well.
My problem is: I want to check the 2nd check box right after the user clicks on the first checkbox and not only after he tabs away by clicking somewhere else.
Right now, I only succeed runing my business logic in the CellValueChanged or CellParsing events but those only occur after the user leaves the checkbox, which is not desired, I d like to run the logic and show the 2nd checkbox checked right after the user clicks on the 1st checkbox.
I also tried: CellClick event but I don t know how to : when the user clicks on a a checkbox, how to change the value of other checkboxes in the current row during CellClick event . The changes does not take effect in the UI !!!
