I am working on a web app for an online photo album. It is the last project in Scott Mitchell's book: "ASP.Net 2.0 in 24 hours".
I am creating a page where users can enter new photo images. The functionality for uploading an image will come later. I am working on just inserting a new row into the Pictures table with an optional category, a required title and a required description.
I am getting an error when I try to insert a new row.
Here is a screenshot of the page with a shot of the dropdown list.
The Categories are user-specific. I am getting the correct values retrieved.
[URL]
There are two pretty simple database tables involved here.
NOTE: The CategoryID and PIctureID are both autoincrement integer columns.
[URL]
The page uses a DetailsView that uses a SqlDataSource that uses the Pictures table. (The DetailsView's Default Mode property is set to "Insert". The "Enable Inserting" checkbox is also checked.)
The dropdown list uses a dropdown control that uses a SqlDataSource that uses the Categories table.
When the "Insert" button is clicked the CategoryID value associated with selected (Category) Name on the dropdown list will be used along with the Title and Description values to insert a row in to the Pictures table. (If no Category value is selected, then a null value will be used for the CategoryID. This is OK because the CategoryID column in the Pictures table allows nulls.)
My problem is that I am getting this error:
Cannot insert explicit value for identity column in table 'Pictures' when IDENTITY_INSERT is set to OFF.
(FYI: I have the full version of both Visual Studio and SQL Server.)
Here is my source code for the page:

I am building an app (ASP.NET 3.5 + SQL 2005) that allow users to schedule meetings and these meeting will show in the users to-do list.
One kind of meeting, when scheduled, should show into ALL users to-do list.
I have 3 tables:
#1 - Users -> UserID
#2 - Meetings -> MeetingID
#3 - Member_Meeting -> UserID+MeetingID
What I need is:
Based on the scheduled meeting, read all users from table #1 and add their info in the table # 3 with the MeetingID (which I can get from the UI, because it will happen when they create the meeting).
I have been browsing about it, but so far, I couldn't find a good source of info to start with.
I have two tables cust and order_cust cust table have cust_id, name, addr, zip columns and order_cust have order_id and cust_id columns I take input from user for cust table i.e. name, addr, zip... the cust_id is an IDENTITY column so generates the value automatically Now I want to insert the last generated cust_id into order_cust (order_id is also an IDENTITY column)
How can I achieve that using stored procedure?

I have two tables - Reports, Usage
Report table:
RId
RName
RGroup
Usage table:
UId
UUser
What I want to do is make a page that will list all the reports in the Reports table and have a checkbox next to each name. A user can check each report they use and when they click "submit" it will insert each ReportID into the Usage table.I'm guessing that I should use a GridView to display all the Reports?How would I make it so that the "submit" button would insert each "checked" record into the Usage table?

I'm joining 2 tables and using the formview. When I insert a record, I need to place the value of the max id + 1 of the second table in a field in the first table so that the tables are linked. I'm not sure where to put the value. I try to put it in the insert command and I've tried the select command but that doesn't work.
Table 1 - Product: ID, ProductNum, Brand, Description
Table2 - Brand: ID, BrandName

View 3 RepliesI m getting following error in my eventvwr . I couldnt find reasons of the following error.
"Transaction (Process ID 110) was deadlocked on lock | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction. "
The only thing my page is doing is inserting/updating data into a table in sql and the thing I can think of is because multiple users are using the same page to insert/update data? Will that cause deadlock?
I want to insert Data Rows into Gridview from web page and I want to send the Inserted Row to Database table.
So I have 3 columns to insert the row.
I added itemtemplate & fotter template with textbox control for each column Inside Templatefield.
I added two buttons [Insert & Cancel buttons ] in fotter template to insert the row in Gridview.
After debugging the page I can't see gridview in my webpage. i can see only EdItdatatemplate items only.Why ?
Can you look at my code & me to insert the records in gridview..
.aspx page,

[Code]....
In short, I have 3 text box fields on an .aspx page named as follows:-
TextBoxIncident
TextBoxDate
TextBoxDescription
in addition a sql datasource is on the page which is connected to the incident table with an insert query which allows the data entered into the fields to be inserted into the database...
The Textboxincident and textboxdescription fields allow the user to enter data into them...
the TextBoxDate field is a read only and the code behind file enables the text box to show the current date and time the code im using is shown below...
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim TextBoxDate As TextBox
TextBoxDate = FormView1.FindControl("TextBoxDate")
TextBoxDate.Text = DateTime.Now
End Sub
When run in browser the textboxdate field shows the current date and time...and Once the textbox incident and text box description fields have been filled in and the submit button is clicked, the fields should be bound to MS SQL table called Incident. This did work before, however it as suddenly stopped working and now displays the following message to me:-
Arithmetic overflow error converting expression to data type datetime. The statement has been terminated.

View 3 RepliesIs there an easier way to insert the values contained in a data table generated in ASP into a SQL table without having to loop through all the rows in the data table and insert individually into the SQL table?
View 4 RepliesIf I create a data tabe in C# like so:
datatable t = new DataTable;
DataColum C1 = new DataColum;//ID column
t.Columns.Add(C1);
//the same with column C2
Then I fill up the table with some data. Then the goal is to either insert this data or update data in an SQLtable in SQL. If the data is inserted, the ID column in t would be empty, if updated, it would not be. So in the insertion case, the sql query needs to make sure that unique IDs are assigned during insertion, in the update case, it just has to look for the right IDs.How to go about this? Asking because I am only familiar with updating and inserting single lines into a table. One could loop in C# over the datatable t of course and insert or update line by line, but this would probably be slow. Is there a way to write an SQL query like this somehow:
Insert Into SQLTable Values (@t)
?
And Update like this:
Update SQLTable SET ... Where C1 = @t.C1
Or something like that.
I know that SQL server can create automatic update and insert queries and that you can then type things in C# like
Adapter.Update(t);
But, this has proven to be super slow on our server, for unknown reasons. I have asked on this forum and got some answers from experts, but was not able to srot out the problem. How can we write a custom SQL query that allow updating and inserting a whole table, instead of just one line at a time?
