Make Gridview Checkbox Field Update Boolean Field In Database?
Feb 7, 2011There 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...
Sql - Make Gridview Checkbox Update Boolean Field In Database?
Nov 21, 2010I'm working in vb.net creating an asp.net web application. I have an SqlDataSource and a GridView on my page:

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).

Checkbox As Boolean Conundrum?
Jun 27, 2009i 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?

Make A Boolean Be Represented As 'yes / No' Instead Of A Checkbox?
May 8, 2012WPF: 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).

View 3 RepliesDeserialize Missing Boolean Field To TRUE?
Oct 4, 2010I'm deserializing a custom object from a file to an object in my app using the XmlSerializer. My issue is that I want a field in the object to default to "True" rather than "False" for a new property that doesn't exist in the file that I am deserializing from.
By default, .Net is assigning this value to be false because it doesn't exist in the file and I want it to default to True if it doesn't exist. I used the System.ComponentModel.DefaultValue(True) attribute on the field in the definition of the object, but that didn't work. Does anyone know how to do this?

Show Bit Column As A Checkbox Column In Unbound Datagridview
May 14, 2010Dim Comp = From C In db.Table1 _
Select C.Completed, C.Taken, C.Namne
Datagridview1.DataSource = Comp
Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values.
I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound.
how can i change this in code at runtime
