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:

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 .
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 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 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:

View 1 RepliesI'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.
I am attempting to bind data from a dropdown list that was populated from another datasourceID. I've bolded what I believe is relevant to this issue in the code below. But basicly its binding the proper county on the pull down menu but when I hit form submit it dosnt postback that info instead its null.

Like the title says, when I try to get a control (HiddenField) using this.Parent.FindControl it returns an exception. Curiosly this only happens when I change the browser language to Italian, English but not Spanish (I'm from Argentina so everything in my computer is spanish).

How to fix this?
I have a form with many form fields and controls, with some offering an "other" if a value does not meet the needs for the user. How can I bind the sql insert so that it will take the ddl selection along with the txt field selection for the "other" value? Even if the txt field is empty it should not be a big deal since the ddl would provide something other than null. Since the column in the db does not allow nulls. I'm using asp.net (vb) 3.5 sp1
View 3 Replieshow can i change exception message language to English without changing the users language
[Code]....
I am developing a multi language website. language change is working very well on master page. from master page I am storing session to use in contant pages.
when I am trying to change text (<p>.....<P>) in content page, thats not working.
protected void Page_PreRender()
Here is the thing. I have an aspx page with NO master page. I have two resource files with the same name (and specifying the language) in the App_LocalResources folder. If I do something like text="<%$ Resources:lblUser %> works fine. What I do to test it is change the browser's selected language.
But, if I do the same in a MasterPage or in a Page that is inside a MasterPage... when changing the Browser's language and refreshing... I'm still getting the default language...
I've been reading some threads about this but the situation was a little bit different.
I have created a web application and generated local resources. Its working when user select language from browser. But what i want is, when user select language from dropdown list, i want to change the pages according to selected language. i can save user selected language in a session. then how should I change/assign local resource file to web page?
