I have the list box control that displays data that has been added from the previous order page. I want to insert the data from the listbox control, into a table within the database when the 'checkout' button is clicked.
View 9 RepliesI have a web page with a gridview & formview (master/detail relationship) combo. On page load the gridview shows all records from a SQL table. On my page I have a button that when clicked shows the formview in Insert mode to allow users to add a new record to the data. I have also added a column to my gridview that has a link. When a user clicks this link it hides the gridview and shows the formview in edit mode with the detail from the record selected from the gridview.
In my formview I am using a listbox control to allow users to select multiple values. The choices in the listbox are populated by a SQL data table. I have successfully written code to post the selected listbox values to my SQL data field during Insert. When the user selects a record to edit I have code in the databound event to select values in the listbox from the choices based on the value in the sql data field. This works as well. My problem is that I cannot figure out the correct code to update my SqL data when a user is editing the record and makes changes to the selected listbox value. I have included my design code for my listbox in my formview edittemplate and also my behind code that I have attempted.

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:

Is 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?

and i also have another problem with a table.i'm able to insert and retrieve the data.but in sql interface all the coloums are empty.where all the data being stored.why i couldnt able to view the data?
If 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?
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?
im looking to insert an array of information into a database table
essentially what id like to do is something like this:
objCmd = New OleDb.OleDbCommand("INSERT INTO pluINFO VALUES *", objConn)
For j = 0 To 265
objCmd.Parameters.Add( info(j) )
Next
this code gives me a syntax error for the insert statement
is there anyway i can set the insert statement that would allow me to add each element of the array(looping through rather than hardcoding several hundred entries) into the table?

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?

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.
