Setting Checkboxes To An Unchecked State?

May 30, 2011

I am using VB Stuido 2008, Net Framework 3.5.I have one Checkbox to Identify the record as Inactive if checked. When I load the form the checkbox is alway unchecked, which is what i want. However, when I go to add a new record the checkbox, not the text for the checkbox is always shaded green, not a checkmark. The checkbox then reacts as if it is checked. This makes it necessary to uncheck the checkbox or else all my record react as if checked.

in the table defintions I have set the default binding value to ((o)) which = unchecked. Iafter setting the default value to ((0)) I deleted the checkbox from my form and then replaced. Not I still get the checkbox shaded which reacts as if Checked.

VS 2008 Getting Total From Multiple Checkboxes?

Dec 8, 2009

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

Counting Checked CheckBoxes Fails?

Feb 16, 2011

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;

Get Different Combinations Depending On Checked CheckBoxes

Jan 15, 2012

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?

List The Number Of Checkboxes Checked?

Sep 28, 2011

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?".

C# - Uncheck All Checkboxes In Repeater Except Checkbox Being Checked

Mar 26, 2010

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.

Save Multiple Times By Doing A LOOP Depending On The Number Of Checked Checkboxes On A Datagridview .NET 2010?

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)

It lets me not select more than 2 and it works fine with the message box.Problem is, I'm trying to count it everytime, then let it reset and count again.Example. I select Barton one time, click vote, then i should be able to select someone new and click vote and it should keep counting.I need to then display my results. Should I just hold the number in a text or Integer file then display it that way?

.net - Dynamic Checkboxes?

I have an page which a user types in a "search" box, the code behind functions/subs etc produce a list of users matching the search criteria. In front of all the users returned in the search results, I have codded a html checkbox. Under the list of results, there is an "email users" button...

so.. I want to be able to click a number of checkboxes beside the results and then click on "email users" button which should take me to another page with email functionality so an email can be sent to all the previously selected users My confusion is over getting the "selected" user list from the results into the email page.

Because the checkboxes are manually coded within the code-behind file (ie the code basically generates a bit of html and pushes it into a label "placeholder", so I dont get any control functionality to get the checkboxes using the vb code, or can I?

I have a form which contains a checkbox field. On page load I want to create a separate checkbox for each customer in my Database. The code I have to create the checkboxes for each customer works fine. However, I also want to check in the database if the customer is set to unauthorized if they are then I want to check there box. I also have code for the case where the user checks a box. If a box is checked I update the database setting the unauthorized attribute to true. My problem is when I check a box it works fine and the box is checked, however if I reload the page all the boxes are unchecked. So either my database update is not updating the database or the way I check on page load for checked boxes is incorrect. Any ideas?

The code for the asp checkbox field:

<asp:CheckBoxList id="check1" AutoPostBack="True" TextAlign="Right" OnSelectedIndexChanged="Check" runat="server">

The Code for the page load:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If box1.Checked = False And box2.Checked = False And box3.Checked = False And box4.Checked = False And box5.Checked = False Then
End If

Is it possible to reference the entire groupbox has having a false boolean property?

While doing this is managable - what if I had more check boxes?
