I want to retrieve the "RowID" for a new Row after an Insert. I am using DetailsView and EntityDataSource. Here is the code I was trying to use:

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 .
I have a page with an EntityDataSource and I want to insert a new item using a FormView. However, the SQL database has a varbinary field which I need to insert an image into.
So far, I have all the rest of the FormView correct and it saves no problem. I can also use the asp:FileUpload to correctly obtain the data. I am assumin that I need to add some C# code to the FormView1_ItemInserting Event Handler, but that is where I am stuck. So far, this is what I have:

Would somebody be so kind as to point me in the right direction with the correct code to add this item to the data I am saving.
I am new to formview .My formview works fine, when I insert data into the database directly and then do an update on it. It throws an error when I try to insert a new record. The error just says
"An error occurred while updating the entries. See the inner exception for details."
How to insert data into the table using an entity dastasource?
What I'm trying to do is similar to the following within the gridview RowDataBound event, only with a detailsview:
DataBinder.Eval(e.Row.DataItem, "TotalPayment")
I created a DataBound event for the detailsview, and it doesnt recognize e.row. I've looked at some reference materials which tell me to use DataBinder.Eval(Container.DataItem, "TotalPayment") but then it doesnt recognize container.
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 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.

Is it possible to code DetailsView to go to the new record I've just insertted? Currently it appears to default to the first record, utlimatly I'd like it sorted Last name, first name and upon an Insert it should go to that new record on pageload.
View 3 RepliesI am using DetailsView to INSERT new records. I have a field "Paid Date"(date) that needs to be pre-populated with the current date. 90% of the time, the user will use the default date, however, there are times when the user will need to change the data as needed. I want to add this default in the code-behind. I DO NOT want to use template item.

I figure that this should be relatively straightforward, but I still can't get it to work. I have a gridview and a detailsview to set up shifts for students and teachers. I would like to be able to insert new shifts using a detailsview. I will limit the students, teachers and location to items that are in a dropdownlist. The problem is that when I handle the iteminserting event. the e.values collection doesn't contain all of the fields I want to populate. How do I add the new fields to the list. This is my codebehind:
Sub On_Inserting(ByVal sender As Object, ByVal e As DetailsViewInsertEventArgs)
I have a dropdownlist in the edititemtemplate of a detailsview. The dropdownlist is bound with an objectdatasource. The detailsview is bound to a seperate objectdatasource which connects it to the insert method. When the page loads the dropdownlist is bound properly. However, when I make a selection and select insert I get the following error: Could not find a property named 'DeptID' on the type specified by the DataObjectTypeName property in ObjectDataSource 'objCurrentProduct'. I've tried to remove the SelectedValue='<%# Bind("DeptID") %> attribute. I can then insert without an exception being thrown but the selected value of the dropdown is not recognized. Here is the code:

Scenario : I have two database tables with one to many relationship. eg:- City and Related news. So I have a gridview(Gridview1) which lists out all the cities and allows edit, delete of the gridview rows. Now since i wanted to display all news for the city, i have a nested gridview as a column in this Gridview1. This nested gridview displays all the news for the cities. And I have edit, delete buttons for this gridview too - So far, good - works fine.
Now what I would like to do is - To insert a new news item for a city. For this, I attached a detailsview to my nested grid(gridview2), and tried to insert. I need the primary key id of city table from the first grid (gridview1) to insert the news into the second database table and I could not access this value from the parent gridview. My gridview1 does not have datakeyname, it is programatically bound.
Also, When the gridview/detailsview is nested, it does not get listed in the event-handler list. So I cannot use say, detailsview1_iteminserting. I do not how to add this event handler
Has anybody done anything similar? When I started, it looked like a pretty straightforward thing - There must be some way to do this. But I just can't get it to work. How do you usually insert into the child table in a one-to-many relationship? Should i just be using two separate gridviews?
I'm inserting data into a SQL database through a detailsview. When a user inserts an incorrect data type or leaves a required field blank it shoots off to a big error screen. Is there a control that I can use that will allow it to give an error (with a little star or something) that says which field is incorrect without the big error screen?

here ResturantId value has to be in session or from Dropdownlist and rest of the value from Detailview. So how to assign that value?
How do I set the value of a field in a detailsview to the selectedvalue of a gridview on the same page? I am also trying to set today date as value of another field in the detailsview as well as UserID. I wrote the following codebehind for the date setting:
TextBox tb = (TextBox)DetailsView2.FindControl("TextBoxCreDate");
tb.Text=System.DateTime.Now.ToShortDateString();
TextBoxCreDate is a template field in my DetailsView.
Unfortunately, I get a Object reference not set to an instance of an object. Error message.
I'm looking to find some command or control that will change fields in a detailsview insert a 0 if there was no data inserted into them. Some example code from my boundfield is:
<asp:BoundField DataField="Assignment_Travel_Time"
My web form contains a detailsview control that I have added a templated field to with a DropDownList in the InsertItemTemplate. The DetailsView default mode is 'insert. My detailsview is attached to a sqldatasource that has a stored procedure in the db to handle the insert. When I enter data in the fields and select insert all values from the detailsview are written to the table except for the selection that was made in the dropdownlist. I am using the ddl.selecteditem.value to populate my variable however when the insert method is envoked it doesn't send my value. The DDL value that I am capturing does not need to be written to the table it is just a flag for some variables that need to be set at the stored proc level. How do I get the DDL selected value to be sent with the insert statement?
Here is my code behind:
Protected
Sub
DropDownList1_SelectedIndexChanged(ByVal sender
As
Object,
ByVal e
As System.EventArgs)
Dim temp
As DropDownList
Dim AccessLevel
As
String
temp = AddUserDetailsView.FindControl("DropDownList1")End
Sub
AccessLevel = temp.SelectedItem.Value
Label1.Text = AccessLevel
I have got a detailsview in my webpage that inserts an item into a database when I click the insert button.
Once this button is clicked, the detailsview dissapears. Why it does this I don't know.
Some of my code:
[Code]....
I guess I'm not sure exactly how or where to do what I need.
First off - here's what I need - - when the user clicks on the NEW button in the detailsView, I have the User.Identity.name captured in a variable and I need to set one of the textboxes (InsertItemTemplate) named 'txtNew' to that name.
I've tried using the ModeChanging (and ModeChanged) event:
Dim
dv As
TextBox =
CType(DetailsView1.FindControl("txtNew"),
TextBox)
If (e.NewMode =
DetailsViewMode.Insert)
Then ....
However, no matter what, 'dv' always shows as 'Nothing', so I can't change the text of it.
Where do I put the logic and what am I missing?
