Thanks in advance.

I'm struggling with trying to use RIA services from an ASP.NET web site.
I created a new web site, added an entity framework model, then added a RIA service that uses that model. I used the DomainDataSource control to bind the ASP.NET controls to the RIA service.
I have a GridView that shows items from the database (via RIA and the entity framework model underneath it), and can see the items fine. I added a DetailsView as a pop-up, as shown in http://mattberseth.com/blog/2007/07/modalpopupextender_example_for.html and http://mattberseth.com/blog/2008/04/masterdetail_with_the_gridview.html. When I click the "edit" link in a row in the GridView, the DetailsView shows with the right data, but clicking the "save" link doesn't actually update the database.
Furthermore, I can't work out how to add new items this way, as when I try and use the DetailsView to add a new item, nothing is sent to the database.
Anyone any ideas how this can be done?
I'm having a DetailsView which has two DropDownList's inside so I should be able to pick 2 values for the field from DDL instead of writing something for it. But I cant get it to Insert any new values to my Database...
Can anyone help me with this? I'm pasting my code and table details here below.
<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" CellPadding="4" DataKeyNames="SignUpKey" DataSourceID="LinqDataSource1" DefaultMode="Insert" ForeColor="#333333" GridLines="None" Height="50px" Width="125px" oniteminserted="DetailsView1_ItemInserted" oniteminserting="DetailsView1_ItemInserting" onitemupdated="DetailsView1_ItemUpdated" onitemupdating="DetailsView1_ItemUpdating"> <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" /> &nb
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? Any help would be greatly appreciated.
Here is my code behind:
Hey,guys. I got a problem about finding controls in Edit/Insert Itemtemplate inside a DetailsView.
Here is the code.
I put a Label (id= "Label6") to test whether the findcontrol method works or not. Unfortunately, I almost tried every means but still coudn't find it.
protected void Page_Load(object sender, EventArgs e)
//Edit Button OnCommand
protected void ButtonEditOnCommand(object sender, CommandEventArgs e)
if (e.CommandName == "Edit")
// Update Button OnCommand
protected void ButtonUpdateOnCommand(object sender, CommandEventArgs e)
if (e.CommandName == "Update")
string sql = "UPDATE StudentInfo SET StudentName=@studentname, Score=@score, Grade=@grade, Remarks=@remarks WHERE ID=@id";
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["sqlconn"].ToString());
SqlCommand cmd = new SqlCommand(sql, conn);
// find controls
if (DetailsView1.CurrentMode == DetailsViewMode.Edit)
TextBox EditStudentName = (TextBox)DetailsView1.FindControl("TextBoxEditStudentName");
TextBox EditScore = (TextBox)DetailsView1.FindControl("TextBoxEditScore");
Can somebody tell me why I am getting this error when I try to insert data in a DetailsView 2.0?
Cannot insert the value NULL into column 'Title', table 'C:\INETPUB\WWWROOT\TEST\APP_DATA\QUIZ.MDF.dbo.Question'; column does not allow nulls. INSERT fails.
I used the Configure Data Source wizard to set this up and Question ID is a autonumber.
When you autogenerate the Insert button on a Detailsview control and click on that button during run time the control posts back with text input areas where you are supposed to type the Title, Answer1, Answer2 etc. Obviously I typed data in to this text area labeled Title. It didn't work and that's why I'm asking about the control. Because I can't debug the control I am having a hard time figuring out where the problem is.
Here is the code and thanks for any help.

I'm having a problem to get the inserted values from the detailsview. I've tried the following things:
// Get Value from DropDown
int TopicID = 0;
foreach (DetailsViewRow row in ItemsDetailsView.Rows)
if (row.Cells.Text == "Topic")
DropDownList TopicDropDown = (DropDownList)row.Cells.FindControl("Topic_TopicIDList");
TopicID = int.Parse(TopicDropDown.SelectedValue.ToString());
For Each row As DetailsViewRow In DetailsView1.Rows
Dim cell1 As TableCell = row.Cells(1)
Dim value1 As String
value1 = cell1.Text
Dim item As New DetailsViewItem(col.ColumnName, row(index).ToString(), col.DataType.ToString(), col.DefaultValue)
tb = DetailsView1.FindControl("Categorie")
s = tb.Text
For Each dvr As DetailsViewRow In DetailsView1.Rows
If dvr.Cells.Count = 2 Th
OK, 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:
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. Any ideas? How do you usually insert into the child table in a one-to-many relationship? Should i jus
I am using VS2010
When I try to updated or insert a record in my User table I am getting an error that does not make sense to me and I cannot figure out what is wrong.
Also, when I try to insert a new record I get a validation error saying that the Id is required. However it is an identity field in the db so it should not be necessary to send it to the server.
Could you please shed some light?

I am coding a .cs file that handles the metadata for a particular table. I am putting a custom validation that allows me to update or insert only if the PubMedID is not already in the database. This would be easy except that the PMID should also be allowed to be null as some of the references in the database were not from PubMed. So i perform a query on the database to see if there is already an identical PMID in the database. This works great when using Insert. However, when using Edit, it does not. The PMID is already in the database because the one currently being edited has the same PMID!!! So I know exactly how to change my query etc. However, I do not know how to tell from inside this Edit/Insert agnostic page, which one it is being called from. Thanks for your help!
