Sql - Make Gridview Checkbox Update Boolean Field In Database?

Nov 21, 2010

I'm working in vb.net creating an asp.net web application. I have an SqlDataSource and a GridView on my page:

<asp:SqlDataSource ID="msgUnread" runat="server"
ConnectionString="<%$ ConnectionStrings:edinsec %>"

[code]....

As you can see I was playing with WithEvents but that didn't seem to help. In the above code all I was trying to get was some kind of reaction to the clicking of a checkbox - but nothing happens (no errors, either).

Make Gridview Checkbox Field Update Boolean Field In Database?

Feb 7, 2011

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...

Make A Boolean Be Represented As 'yes / No' Instead Of A Checkbox?

May 8, 2012

WPF: Display a bool value as Yes / NoI'm writing a WPF program in VB.Net 2010 (.NET 4.0) that uses data binding against a simple class that is an ObservableCollection of another simple class I've written. So far I have a DataGrid that shows the information and I can add and remove items as necessary, but I seem to be stumbling with a fairly basic concept:How do I display data in some way other than the default behaviours that the various DataGrid columns allow?I have a boolean called "reversed" in my original class, let's call it "x". I would like the DataGrid displaying the ObservableCollection of "x" to display "Yes" or "No" under the Reversed column instead of a checkbox that is checked or unchecked (DataGridCheckBoxColumn).

Populate A Checkbox Field In A Gridview?

Feb 15, 2012

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.

How To Generate CheckBox Field According To Integer Value In Database

May 9, 2012

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);
[Code] .....

How To Update A Database With The Value Of A Bound Checkbox

Apr 30, 2011

On a Windows form I have a checkbox bound to a datatable. In the CheckedChanged event I do .EndEdit on the bindingsource and then .Update on the tableadapter. At runtime this gives an error: "Data Table internal index is corrupted: '5'.

If I change to the Validated event, there is no error, but the new state is not sent to the data base untill focus is subsequently lost, which is a problem. So how am I supposed to get the new state of the checkbox written to the database when the checkbox state changes?

Update Row In Database But Skip One Field?

May 13, 2009

I have written this set of code that will update an Access Database row: (Total_RAM, Model, etc are just string variables)

Dim Record As InventoryDataSet.InventoryRow
Record = frmMain.InventoryDataSet.Inventory(0)
Record.BeginEdit()
Record.Total_RAM = Total_RAM
Record.Model = Model

[code]....

My problem is the fact that one specific record called "Record.Asset_Tag" exists in the database, but I don't want to programically alter it. That will need to be typed in manually. However, even if I don't put in the line "Record.Asset_Tag = ...", it will overwrite anything in the field with a blank.How do I keep whatever is in the database unaltered in the Asset_Tag column?

Asp.net - Update Database Based On Gridview Value?

Mar 13, 2012

I have a grid view which uses SQL to calculate information that I need! I want to put this calculated total into another table in database.

SELECT StaffDetails.StaffID, SUM(HolidayRequests.RequestTotalDays) AS Expr1
FROM HolidayRequests INNER JOIN StaffDetails ON HolidayRequests.Username = StaffDetails.UserName

[Code]....

It basically calculates the total number of approved holiday requests for a staff member which is correct. I want this number to then update the HolidayTaken field in another table each time a holiday is approved.

I have tried an update however you cannot use an aggregate in an update as I have found.

Checkbox As Boolean Conundrum?

Jun 27, 2009

i have a form with text boxes for username, initials, and password on.Also on this form are a few checkboxes which at the minute i simply want to save their state to SQL as true or false depending if ticked or not. The checkboxes or text boxes are not bound to anything, and are used only for creating a new record in the table.There is a gridview below these boxes showing already created records.The code im using to insert to SQL with is:

If String.IsNullOrEmpty(UsernameTb.Text) Then
MsgBox("You must enter a Username!")
Else[code].....

For some reason when i create a new record, it saves the check state as -1 for checked, and 0 for unchecked. the table columns are varchar(5) for the check boxes.Using checkboxname.checkstate doesent work either - that saves the state as 1 or 0 (as opposed to -1 and 0)On another form i made for editing existing entries, i have the same text boxes and check boxes, which are bound so they show the record details. when using that form to EDIT an entry, it saves the check box states as "True" or "False" as it should do.Im completely stumped here, because if i create a new user it then breaks the gridview showing users, because it throws up error messages about "-1 not being valid boolean" when it attempts to render each check box in a grid view. how i can make the insert save the check box state as boolean?
