Handle My Record Update, And Move To The Record Number The User Entered?
Oct 27, 2009
I am handling many of the BindingNavigator tasks (MoveFirst, MoveNext, etc.)in code to ensure that I always ask the User to save his changes.
The one area I am have a problem is PositionItem. I would like to sense that the User has changed the Record Number in the BindingNavigatorPositionItem, handle my record Update, and move to the Record Number the User entered I have looked all over and have not found any way to do this.
I'm using a bindingnavigator. My datasource has the column "key1" marked as unique = true. The user presses the "+" button on the screen. A blank form is presented as expected to allow entry for the new record. The user enters "A" in the "key1" field, "A" already exists in the dataset as all records have been returned by the fill command of the tableadapter, the user then, without attempting to click the save button, clicks in the "PositionItem" textbox in the bindingnavigator. They then enter a number (say "1" for instance to go to the first record in the bindingsource), when they press enter an unhandled exception of type ContraintException is thrown. The exception is expected since the Constraint is not met. But how can I handle this exception, or how to I reimplement the code to do the work of the "PositionItem"? I know how to override the "movenextitem", "movepreviousitem", etc.
I am trying to add a new record everytime i do my navigation gets all messed up I also need an update button... I would like so when i hit new record the record of will be(ex. If Im adding record number 30 it will say record 30 of 30, hit add new it will say record 31 of 31) my code is below.

On my website I have user records. For the user records page I have three options you can do with each user record. Delete, Update and Email are my checkboxs's that I am trying to use.
What I want to be able to do with these check box's is when one of these slections are made, I want to be able to pass the value of the selected checkbox by pressing a button over to another page where I have a IF statement. Then value of the selected checkbox runs though the IF statement and matchs with the option in the IF statement.
[Code]...
So I guess what I am looking for is how do I get the value of the checkbox to pass over to another page and run through my IF to match with an option in my IF statement.

While I've previously many years of relational databases and procedural languages, I'm stumbling with Visual Basic. In this problem, the simple situation is that I have two files, parent and child. The primary key of the parent file (Area file) is linked by a relation to one of the two fields that makes up the primary key in the child file (Project file) (unique key is formed from 'area' and 'project'). I have the default table adapters created on both files. I have created two maintenance forms showing one each of the two files in datagrid view format.I can create some records in the Parent (Area) file, but when I try to create a record in the child (Project) file, using one of the valid key values from the Area file, I get the 'ForeignKeyConstraint [relation name] requires the child key values [actual value] to exist in the parent table' which I'm absolutely definitely sure it does.
I haven't done any actual coding for those two maintenance forms, just dragged-and-dropped the files from the data sources screen onto separate forms so it creates the controls itself. But I can't work out, if it already knows the data does exist because I can load it back in to the Area maintence form, why it can't check itself to find out the record does exist. Why does it think the record from the parent record doesn't exist? It does exactly the same thing, whether or not the database is in access or SQL Server Express. I have all the latest updates.
I have two tables Products and Categories with a many to many relationship. I am trying to copy the categories linked to one product (OriginalProduct) to another product (newProduct). The problem is when I execute the SaveChanges() method, I not only get the records in my linking table, but it also creates another copy of the categories in the categories table. I've tried this in many ways but here are the last couple that I've attempted:
' Copy Product/Categories For Each oneProdCategory In OriginalProduct.Categories Dim relatedCategory = _productContext.GetObjectByKey(New EntityKey ("ProductInfoEntities.Categories", "RecordId", oneProdCategory.RecordId))
I have a problem with my program, and it's really bad because I need to burn it to disk within 12 hours and I can't get it to work: If I create a record, add information to it and click on Next Record, the ID, Status and Notes boxes content will change but the rest of the controls contents are carried over to the next record and I don't know why or how. It was working perfectly but now it stopped and I never done anything.
I have created a project that has an add a new record, edit record and a search form, that has multiple text, combo boxes and is working great.Last nite I have added a checkbox under my add new record form and i am saving the checkbox value to my database, so far so good. I would like to be able to search any record that is mark with a checkbox to show up in my search screen when I do a search: [code] The problem that i am having is that now that I have added the code to my project to search for the checkbox field in the search screen and if I leave everything blank and click on the the search button I get no record found. I expected to see all that data, since I have nothing selected. Now if I click my checkbox, as soon as I click on my search button I see that two records that I have added for my test.
