Checkbox In Datagrid A Field In Sql Table?
Mar 18, 2011
I am using a VB.Net form in which I have a table of sql. In it is a boolean field.
I want to show this field in a form as checked if that field value is true and if false then it should not be checked. Is this is possible?
If possible please help me with the code which I have to type to make that column in the datagrid view to checked or not.
I have created the sql inside vb.net using add new item and then a database.

I have a field in my table called RentPaid, its set to bit data type. On my form I have a button called Pay Rent, when the user clicks that button I want my checkbox set to true.
I've tried both of these:
Me.chkRentPaid.Text = True
Me.chkRentPaid.Checked = True
Neither seem to be written to my SQLExpress database, however EVERY other field on my form does. The field shows up in my datasource for that form, I just dragged it over to my form with the rest of my fields.

There are lots of questions about this but I've not been able to solve my problem using the answers to any of them (after many, many attempts..)
I'm working in vb.net creating an asp.net web application. I have an SqlDataSource and a GridView on my page.
I want to change the DoNotMail boolean value represented by a Gridview checkbox and automatically update in the database if the checkbox is checked from 0 (False, Will Mail) to 1 (True, Won't Mail) here is the code I used. [code]...
is it possible to do a two way sync on the entire gridview when the user hits a button so you don't have to do an update every time a row is changed? because the user might check the box and then check another box then uncheck a box and it would be a lot of updates...

I have a datagrid who's ItemsSource is a strongly typed IEnumerable object In this datagrid, I have a checkbox column, a price column, a part name column, and a 'total selling for' column. On checking the checkbox I need to update the total selling for column with the value in the price column. This part I have working, however, how can I get the checkbox to remain checked when this happens?
Private Sub UpdateSellFor(sender As System.Object, e As System.Windows.RoutedEventArgs)
Dim _CB As CheckBox = DirectCast(sender, CheckBox)
Dim _ID As Integer = _CB.Tag
Dim _PP = DirectCast(DG_PartsToSelect.CurrentItem, PartTyping).PartPrice

I am creating a database in VB.NET for a movie rental place. I currently have three forms;
Member Information
DVD Information
Borrow DVDs
What I would like to do is when I am viewing a member's details, if I click a button 'Borrow DVD for Member', the member's ID number transfers over to the Borrow DVDs table in the Member ID which also would hold some information from the DVD Information table, but I'm sure if i can figure out how to do this firstly, I will be able to apply the same rule and work it out myself.I have been trying to use a query statement like;
INSERT INTO [Borrow DVDs].[Member ID] [IN goodstuffvideos.mdb]
SELECT [Member Information].[Member ID]
FROM [Member Information]
but that has been coming up with error codes and completely not working.
Borrow DVDs table fields are: Borrow ID, Member ID, DVD ID Number, Hiring Fee, Borrowing Limit?
DVD Information table fields are: DVD ID Number, Title, Rating, Hiring Fee, Borrowing Limit Member?
Information table fields are: Member ID, Family Name, Given Name, Address, Town/Suburb, Postcode?
The error coming up is; Error in INSERT statement. Unable to parse query text.And under that it says The query cannot be represented graphically in the Diagram and Criteria Pane.

Here is hte code I'm using to insert into my database:[code]I believe it is Cell 4 that is causing the exception, because it is a checkbox column and i'm not sure what syntax to use to store the "CheckedState" of it.Yes, I know I should be using parameters, but I don't know how yet, and I would like to make the INSERT statement work before implementing the paramater approach with it.

I want to populate a checkbox field in a gridview.
I am using the Checked='<%# Convert.ToBoolean(Eval("Inactive")) %>' statement but the issue that I am facing is that in the database some records contain NULL for Inactive. If it encounters a 0 or 1 value it works fine but if NULL it throws an exception.
Kindly guide me how to populate the checkbox so that it should be unchecked even if the field is null.

I want to generate checkbox field using GridView and system will calculate how many field to display according to number of totalDay. If totalDay stored in database is 7, so upon calling the eventID it will generate 7 checkboxes, D1-D7 checkboxes field will appear; if totalDay is 5, it will generate 5 checkboxes, D1-D5 checkboxes field will appear.
In PHP, I manage to auto generate number of D field I want according to value totalDay. But I do not know how to code in VB. The PC Fair Event has duration 7 days, so it will display 7 checkboxes after user select event and booth to book: The Carnival 2012 has duration 5 days, so it will display 5 checkboxes after user select event and booth to book:
The code in PHP which can generate the checkbox:
$query = "select * from booths, eventinfo where booths.eventID=eventinfo.eventID && booths.eventID = ".$id."";
$_SESSION['EVENT_ID']=$id;
$result = mysql_query($query);
$result2= mysql_query($query);

I am working with Vb.net. See the code below; I have the following problem - when I click the checkbox (Cells(3)) the value remains 0.00 in Cells(4) unless I click another checkbox is when Cell(4) gets populated with the value from Cells (5).
What I want it to do is when cells(3) is checked, Cells(4) should be populated instantly with the value from Cells(5). Rather than still show 0.00 until another checkbox is clicked. I think th eproblem is in the eventhandler as highlighted

I am limited to using ASP .NET 1.1, as for this environment I cannot upgrade to 2.0 or beyond Essentially, I have a very simple datagrid that has a checkbox in one of the columns, which is a template column...the code for the datagrid is this:
<asp:datagrid id="dgDates" OnItemCommand="gridEventHandler" BorderColor="Black" BorderWidth="1px"
CellPadding="3" runat="server" AutoGenerateColumns="False" HorizontalAlign="Left" AllowSorting="True"
OnSortCommand="SortData" OnItemDataBound="gridItemDataBound">
[code]....
Now, my issue is that when I set cbStaticRolling to the CheckBox control through FindControl on the e argument, it seems to set the variable okay, but doesn't seem to be setting the right one, or setting it properly, because "Checked" property is false regardless of whether I check the box or not?

I have a tbl called tblProjectpatients which also has 2 fields Yes and No (these have the data type - Bit).
These two fields have been populated with false and true values.
On my form, I have a datagridview which is populated with various values from tblProjectpatients.
The problem am facing is that the checkbox's for Yes and No on the datagridview are empty at runtime eventhough at the backend they have either False or True values.
I am expecting the checkbox showing on the datagridview to be either checked or Not Checked depending on the True or false values.

I haven't seen a related thread (yet)I have a VB windows application that uses a datagrid to display a text column and a checkbox column. Only one row in the display can have a checkbox entry = true. If a checkbox is selected, the app is to search the rows and all other checkbox entries are to be set to false.My event handler is: Private Sub dgMember_CellContentClick(ByVal sender As System.Object, ByVal e As ystem.Windows.Forms.DataGridViewCellEventArgs) Handles dgMember.CellValueChangedI first had to have this handler code check a flag and exit if true (when initializing the display) because it was called for each row during initialization.

Interesting problem. I have a datagrid with several columns which are bound to an Access database. Here's the situation...I'm concerned with the 3rd column.This is what I'd like to happen... when the 3rd column(is a checkbox) is checked then column 4(TIME_USER) would be populated with the current time
Basically, this application is meant to keep track of tasks that the user has to do at a certain time of the day. When the user checks the checkbox it would record the time in the database for that task as to when they did it. I found some code from a forum that i changed to fit my needs, but it's not working.
