DataSource Controls :: Insert A Foreign Key Into Detailsview?
Jan 28, 2010
I am trying to insert a foreign key into detailsview so that user didn't have to enter value every time. I am using the following code to do this but it is failing. I am not sure what needs to be done now.
Protected Sub LinqDataSource1_Inserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.LinqDataSourceInsertEventArgs) Handles LinqDataSource1.Inserting
LinqDataSource1.InsertParameters("Company").DefaultValue = Session("Company_new").ToString()
End Sub
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim company As String = Request.QueryString("Company")
Session("Company_new") = company
End Sub
End Class
There is this error troubling me whenever i tried to do something to the ShopCart such as add to cart.
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_ShopCart_Shopper". The conflict occurred in database "DIYERA", table "dbo.Shopper", column 'ShopperID'. The statement has been terminated.
I checked the database and the foreign key, ShopperID, was set correctly.
I am using 1 textbox with a Ajax Calendar extender to allow my user's to select a date graphically (exp: 12/15/2009). I have another textbox for the hour and minutes in military time(exp: 15:30). I think i have the code to grab the data from the 2 textbox's and combine them to be inserted into the field (exp: 12/15/2009 15:30). Here is my insert code for the Field:
[Code]....
However unless I make all the fields Nullable the insert fails, on top of that none of the other field that I have selected on the Detailsview Insert or Edit are inserted into there fields. Half of my fields have to be non-null values. So how do I fix this?
I can supply additional vb code and the aspx code if needed.
This is the error I'm getting: Cannot insert the value NULL into column 'Operation_type', table '/GAOSDB.MDF.dbo.BC_Perf_Log'; column does not allow nulls. INSERT fails. The statement has been terminated.'
This is the first non-null column.
I need to get this figured out because I have 30 other web pages that will be utilizing the same approach.
I am trying to create a stored procedure where I can insert null values in columns that have a foreign key constraint and allow nulls. The columns I am trying to insert nulls into are commentid and imageid. I have created an Insert statement in a stored procedure and I get the foreign key constraint error. Can you tell me how to allow inserting data in the other columns without having to insert anything in the commendid and the imageid?
Here is my exec of the stored procedure that is not working:
I am trying to use the TableApapterManager.UpdateAll to insert values to master and child table. I had set the relation to cascade for update in the dataset and the HierarchicalUpdate to true. But stil when I run TableApapterManager.UpdateAll(dataset), I get a foriegn key violation error. Following is the code I used:
The error I get is "The INSERT statement conflicted with the FOREIGN KEY constraint "FK_MemPhones_Members". The conflict occurred in database "Family", table "dbo.Members", column 'i_memeberid'. The statement has been terminated."
I'm trying to catch (in string "s") the primary key for the record being inserted via DetailsView. I have an SqlDataSource connection to an Access 2003 database. The primary key is auto-increment integer (long) field.
Not sure where I went wrong with this one, but I can't figure it out now... I've got a DetailsView in an UpdatePanel. A dropdownlist controls which person's details are displayed in the DetailsView. I have the DataSource set to an ObjectDataSource, which has select, insert and update methods defined. I also have a method for the ItemCommand, ItemInserting, ItemUpdating and DataBound events of the DetailsView specified.
When I click "New" or "Edit" on the DetailsView I get the open form with either the details for the current person, or a blank form, exactly as I would expect. But when I click the "Update" or "Insert" buttons it does absolutely nothing. I have it running in debug, and have put breakpoints in the ItemCommand, ItemInserting and ItemUpdating methods, right at the top, and it never goes there. The form remains open, and nothing happens. If I click "Cancel", it posts back and goes back to ReadOnly mode.
A couple more minor details that may be important: This page is using a Master page, which is where the ScriptManager is. I'm actually using the ScriptManager from the AjaxControlToolkit. I also have a GridView in this same UpdatePanel, and that has a FileUpload control in it. Because the FileUpload control doesn't work properly without some tweaking, I have to call a RegsiterPostbackTrigger method on page load to link it back to the Master page's scriptmanager. Not sure if that's causing any issues...?
I had this working fine, but then as the page got more complex and I had to change some of the code, at some point it just stopped working and now I can't figure out how to get this working again... I'm happy to post code if necessary, just thought I'd try this first to see if anyone has a quick idea for what to check.
I'm not sure if you would consider it a foreign key field or not, but I have an agency table with an association to my Project table. It exists primarily to limit the input values of agency in the Project table to those listed in the Agency table. Anyway, everything works fine, except that when you insert/add a project, the Agency field is moved to the end of the list. I'd like to move it back where it belongs (further up the list).
I have a scenario in which the user can add a new option to appear in the list of available choices in a DDL contained in a detailsview when they select an option <Add New>. This displays an AJAX model popup which then allows the user to enter the new option text. Then they hit an Insert button which inserts that new option into the DDL's datasource and I call ddl.DataBind. Subsequently I want to close the modal popup and then display the newly created DDL option as selected.
When I step through the code, everything appears to be working as expected...i.e. the DDL's datasource now has 1 more record than before and the ddl.SelectedValue is the newly created record for its datasource. I can also query ddl.items(99) and see the new option is part of the ddl's items collection and the new record is Selected.
HOWEVER, once the screen comes back from the debugger, the DDL is now showing the newly created option, but still the prior selected option of "<Add New>". And if you pull the DDL down the newly created option is not in the list?
I cannot figure out how that happens...though I suspect it has something to do with the AJAX/Update panel. Here's some code:
In my detailsview, I have an emptydatatemplate set up to allow users to enter new records. The code works. However, once the record is inserted, the detailsview defaults to a standard insert screen. I know this will cause confusion for the users. I would prefer the detailsview to either show in edit mode or a read-only mode. I have used detailsview.changemode and detailsview.currentmode in the custom sub created for the add new button of the emptydatatemplate- neither of which do what I was hoping. It would be even better if when there was no data, it defaulted to the insert screen (which seems like that should be an easy, no-brainer way for .net to function) but it doesn't. Or, I don't know how to accomplish it.
I don't want to force the user to click cancel after inserting an item through the emptydatatemplate just to be able to use the detailsview for other records.
I have a database with a 1 to many relationship in SQL Server 2008. I have created a formview in VS2008 to insert records into the child table. However I can't set the foreign key to automatically insert this value. If I manually type in a value the insert works but I need it to pick up the fk ID automatically from the master table. How can I do this?
The master table: tblTopic has ID int auto increment primary key and the child table has ID int auto increment primary key and TopicID int allow duplicates no nulls, foreign key. I have set updates to cascade in the relationship.
My insert statement is INSERT INTO tblTopic (TopicID, Comment, SubmittedBy) VALUES (@TopicID, @Comment,@SubmittedBy). The TopicID keeps throwing the error, this is the foreign key.
This is the first time I have tried to do this, so apologies if it's really obvious but I'm on a bit of learning curve.
I have a problem with DetailsView linked with Database, DetailsView is Insert/Edit enabled, and adding/ediditng data works, however........ when I add a new record (DetailsView in Insert mode) and press INSET instead going to record I have just created in Read-Only Mode it shows me blank form, it looks that the "linking" field is null.
I need to populate the foreign key coloum in the table.
i have three tables PATIENT DETAILS ptID firstName lastName address IMPLANT DETAILS impID ptID productID productSerialNo PRODUCT productID productName
I am instering data in PATIENT DETAILS and IMPLANT DETAILS table on the same page from single button click .
I have a foreign key on the table IMPLANT DETAIL (productID) which i populate through the value on the dropdownlist .
What my problem is how will i populate foreign key (ptID) in IMPLANT DETAIL table. When ptID (PATIENT DETAIL) will also be generated from the same button click at almost of the same time.
I am inserting a record and want to set the value for a foreign key but I am getting an error - I initally thought that it would insert it if it didn't exist but I must be wrong and want to confirm that I need to check all values and make a record for them if they don't exist... here's what I am trying to do - does his make sense?
var newAllPart = new Part(); newAllPart.PartNumber = partNumber; newAllPart.Manufacturer.ManufacturerName = partManufacturer; // error here if the Manufacturer doesn't exists already newAllPart.PartType.PartTypeName = partType; newAllPart.Category.CategoryName = partCategory; newAllPart.DateCreated = DateTime.Now; newAllPart.UserCreated = userCreated; newAllPart.Package.PackageName = partPackage; newAllPart.Statuse.StatusName = partStatus; localDB.Parts.InsertOnSubmit(newAllPart); localDB.SubmitChanges();
when i do currentCustomer. In the drop down I can see all the columns listed except one column which is a foriegn key from order table , how do i insert into intorder_fk
Getting the message that ObjectDataSource ... count not find a non-generic method ... that has parameters ... The parameter list is fine until I get to the very end and it list the two data fields that are in my DetailsView. Using the ASP Tutorial #17 (Examining the Events Associated with Inserting, Updating, and Deleting) and the Exploring the Data Modification - specifically the one showing the INSERT of the Product Name and UnitPrice. ASPX page is pretty simple and attempting something similar, two fields to insert a new record - update the other fields later.
Full Error Message follows along with ASPX and the AsignaturasBLL.cs. Interesting thing is that when I swap the two fields in the DetailView, then the last two fields in the error message are swapped. In the error message I bolded these two fields.
I m try to insert record to table, its working well without foreignkey using Entity model. But i need to insert foreign key. I used the following query, its not working well via Entity model.
objFacility.FacilityCategoryReference.EntityKey = new System.Data.EntityKey("testEntities.test", "id", 10);
I cannot get the value from the drop down list and I not sure what's wrong with the declaration and the code.
Dim selectedIntake As String = intakeDropDownList.SelectedItem.Text() Dim selectedSupervisor As String = supervisorDropDownList.SelectedItem.Text() .supervisor_ID = selectedSupervisor(0), _ .semester_No = selectedIntake(0) _
[Code]....
This is the error message I get :
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_student_Details_lecturer_Details". The conflict occurred in database "SKTM-AAS", table "dbo.lecturer_Details", column 'supervisor_ID'. The statement has been terminated.
i am currently working on an asp.net mvc 2 web app using LinqToSQL. I would like to handle a scenario where a user comes form a country and for this i have set the users - countries db relationship and in my user model i have a CountryId property.
I would like to display the country name on my users display view, so i tried fetching the country name like this: User.Country.Name, but an exception occurs that i cannot access a disposed object. I understand that this is caused by the way i handle my users repository and service.
This the repository users code:
[Code]....
This is the service users code (the repository is not class level property, but a local one that gets dipsosed immediately after calling it):
[Code]....
So, how could i handle such a scenario, where i would like the Country model to be also fetched in order to use it later? Should i convert the repository model a class level proprty in order not to get disposed?
