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...
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).
I have limited knowledge on VB coding. I am now creating a system which allow customer to select exhibition event and booth number they want and next reserved which day they want to rent.By default, in GridView control can add checkbox Field but it only generate 1 checkbox for 1 row of data.
As state in the title, I have no idea how to generate the checkboxes for every field in database call D1,D2,D3,D4,D5,D6 and D7, each carry value 0 by default.Now I want every single field have a checkbox to allow customer select which day they want to reserve and retrieve their checked value to stole into corresponding D1-D7 field, checked value will update value 0 to 1.Next, how should I coding to store the checked value into database? in default.aspx or default.aspx.vb? generate checkbox instead of using gridview?What I want
I have a gridview with a template field and inside the template field is a checkbox field.My question is how do I capture the event when a checkbox is ticked and how do I reference that row which has been ticked?
Dim query as String = "Select * from openquery (devbook, 'SELECT wb.arrival_time FROM web_bookings wb ')"All I need is to convert my arrival_time into a datetime field in the query
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); [Code] .....
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?

I'm using a MS Access 2007 database. I modified the field definition of one of the fields in a table, it a text field and I change the maximum length from 40 to 150. I have a data source in my app that contains this table and many others. I refreshed the data source but the change didn't take affect. I went through configure option but the change still didn't take affect. It gives me this error, The value violates the MaxLength limit of this column. If I add/delete a database field the data source is updated when I go through the configure process. I finally just deleted the table from my data source and then added it back.
I'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?

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.
I have a datagrid which is built with 5 fields i.e, prac_no, prac_eid, num, ToPay (Checkbox) and Amount. prac_no, prac_eid, num and Amount are extracted from a query in SQL server and when the form is loaded the 4 columns are populated. The ToPay check box is (unbounded column) set as True by the following code in on load event;[code]What I want to do is when the checkbox (ToPay) is unchecked then Column 4 (i.e, Amount) is set to Zero.

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).
how can i bind a checkbox to a dataview field? the dataview will only have 1 row, but i want checking + unchecking the checkbox to update the dataset. how can i do that?
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.
