Forms Data Controls :: Cannot Insert The Value NULL Into Column 'idUser'?
Mar 1, 2011
I have this error when trying to insert a new record through a 'New' button in asp:DetailsView control. Error details:Message: Sys.WebForms.PageRequestManagerServerErrorException: Cannot insert the value NULL into column 'idUser', table 'C:INETPUBWWWROOTVIEWS1APP_DATADBSEARCHRESULTS.MDF.dbo.UserDetails'; column does not allow nulls. INSERT fails.I have an typed dataset xsd & adapter, where i automatically generate delete, update, insert commands. I also use SqlDataSource.The field idUser doesn't allow nulls on database level, and in the xsd I marked the following properties:AllowDBNull = false, AutoIncrement = true, AutoIncrementSeed = 0, AutoIncrementStep = 1, ReadOnly = true, Unique = trueMy code is:
[Code]....
How to solve the problem or where I should look for the problem?p.s. If i have in DetailsView, idUser field properties set: InsertVisible="True", ReadOnly="False" and i enter a value manually, the records successfully inserts.

so i have a FormView bound to an SQL datasource.
Using the Auto generated insert/update/delete. "Cannot insert the value NULL into column 'UniqueID'"
The FormView Default view = Edit
I have set the PKey and the Datasource is loading the record from a session. The record is loading no problem, just wont update.

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:

When I use the Insert option on the view it causes an error due to it trying to insert a null into the primary key field. If the Insert function does not create a new primary key entry how is it created?

I setup a very simple example using a DetailsView and an EF Model with Contact, Individual, and Customer from the AdventureWorks database (2008). Viewing, Editing, and Deleting work just fine. However, I'm getting the error when I try to create a new Contact.
Here are the relevant code snippets:
[code]...
I get the dreaded error:
Cannot insert the value NULL into column 'PasswordHash', table 'C1AdventureWorks.Person.Contact'; column does not allow nulls. INSERT fails.
I've monkeyed around with the StoreGeneratedPattern="Computed" and DefaultValue="0" for the PasswordHash property in the Contact entity as well, but it didn't .

here is my latest bit of insanity. I'm using a formview control. In the insert template, I'm grabbing applicable values from my AD to populate a dropdown list. I select the user I want to insert, enter the other pieces of info required for my request and click Insert. The query responds back stating that the userid is NULL. So the big question in my mind is how can I bind userid to the dropdownlist if I'm populating that from the code behind? Here's my code behind code for that list:

Basically, the user Selects a row on GV that executes an Insert into a table the GV cell values of the selected row.
The SQL field data type is varchar. If the GV field is Null, the Insert adds the value to the SQL field. How do I keep the @nbsp; from being displayed in the cell of a data control when it is called at a later time? Do I add some more asp to my control parameter? do I add some vb code behind? Here are some relevant code snippets of existing code.

I have a formview on a web page, set to insert mode as default. The form view is bound to a SQLDatasource. This datasource has a custom query written to select the details for this formview. The query joins two tables to provide relevant detail and not just an ID for one of the elements on the form view.
The first tabe contains information regarding projects and the second table contains detail regarding Resources. First table has the following definition:

on my aspx I have the below DDL
<asp:DropDownList ID="ColorDDL" runat="server" DataSourceID="ColorObj"
DataTextField="Size" DataValueField="BustId" Width="150px"
AppendDataBoundItems="True">
<asp:ListItem Value="-1">(Optional)</asp:ListItem>
</asp:DropDownList>
If the user does not select an item I get an exception when i call the ObjectDataSource Method and DAL as below to insert into database
ProfileObj.InsertParameters["ColorId"].DefaultValue = ColorDDL.SelectedValue.ToString();
What I want to do is insert a database NULL instead.

I have a DetailsView for inserting values and currently the columns are center aligned. What I want is to have my "label" right aligned and my "text box/dropdown box" left aligned.
Something like:
Name: _______________
Address: __________________________
Phone: __________
Insert Cancel
If I change the alignment to left for both, the Insert and Cancel buttons on the bottom of the control also shift to the left, and I'd like them to stay centered.

I've been working on this project which requires me to insert data into a database. Due to the complexities of the function that I am doing, it is more complex to use SqlDataSource and hence I've used the traditional method of inserting to the database. The codes are as follows:
[Code]....
I am not too sure why, but even though I've debugged numerous times and the data gets inserted into the database through the form view, I get this error on the page after everything is executed: Cannot insert the value NULL into column 'reviewDate', table 'ProrsumDB.dbo.Review'; column does not allow nulls. INSERT fails. The statement has been terminated. reviewDate wasn't null when I tried and there are no exception thrown.
