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...

Transferring Data From One Field In A Table In A Database To Another Field In A Different Table But Same Database In .NET?

Jul 22, 2010

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.

Select All Records Where A Field Is Null Using LINQ?

Jan 25, 2012

I've got a table that caches calculated values for certain dates. I want to use LINQ to select all rows where the calculated value fields are null.But when I use isNothing I get an error that LINQ can't translate this into T-SQL. Is there a way to select null values with link, like this...?

Dim var = From rec As Record In myDataContext.Records Where IsNothing(rec.calculatedValue) Select rec

Other posts on stackoverflow mostly discuss how to avoid or check for null values with LINQ.

Note: I can't just set cacluatedValue's default to -1 to flag records whose calculated value has not been set (and then select those records) because I run queries that sum/average the calculated values. Selecting nulls seems cleaner and less bug-prone.

VS 2010 - Select The First Field Listed On The Left Side Of The Window

Nov 5, 2010

I just started using VS 2010. This product is supposed to be so much better than VS 2008 yet I'm noticing a couple of glaring things that are failures if you ask me.

1. When designing a Gridview, after having clicked on Edit Columns, in VS 2008 I could select the first field listed on the left side of the window, set a property--say headStyle-- and set the Horizontal Align to Left. Then if I clicked on the next field, that same property would still be selected on the right side of the window. In VS 2010, I have to go through finding the property and then expanding it and selecting it for each individual field. While it seems like a small thing, it's time consuming and kind of a pain. Is there some reason they couldn't have made it behave the same as in VS 2008?

Add New Row In Database, Get -1 For ID Field

Aug 6, 2009

I'm trying to make an appointment scheduler here. The table has an AppID column which just increments 1 every time a new appointment is added. That works fine. It also has an ID column that gets a unique doctor ID assigned to it so the program knows which doctor has which patient.

Now, when I try to add a new row, no matter what I try, the ID field gets a -1. I've tried assigning it the doctor's ID that I'm currently browsing as well as hard coding it to be a "3" and it still shows as -1. So this means that while it [B]does[/B] save and update the new row, it adds that -1 in the ID column and thus the program can't tell which doctor has it so it won't show in my program. I don't know if this is because I've tried so many data sets that it's getting them confused or what, but here is the code that I am using to try to save this:
