Forms Data Controls :: FormView - Inserting A Value From A Joined Table?
Mar 11, 2011
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
(Brand from Table1 is linked to ID from Table 2)
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
DeleteCommand="DELETE FROM [Product] ..."
InsertCommand="INSERT INTO [Product] ([productNum], [Brand] VALUES (@productNum, @Brand)"
SelectCommand="SELECT Product.ID, Product.Brand, Product.Description, Brand.ID, Brand.BrandName From Product INNER JOIN Brand ON Product.Brand= Brand.ID"
UpdateCommand="UPDATE [Product] SET [productNum] = @productNum, [Brand] = @Brand ......"
I am doing a management system . What i am trying to accomplish is that when a user fill form relevant to management system the data should go into respective tables.How to accomplish this.I am using primary keys and foreign keys
When I inserted item to database, the Form refresh and return to all blank or standard selection. What can I do if I want it keeps the last entered value after inserting record ?
I need this because there are many items to insert and only partial fields need changes from last entered records.
When page load it is invisible. I have a button1 onclick make it visible and people can input data the press insert. I set it invisible right in Formview Insert eventhandler code.
When people click that button1 again to add 2nd record the form appear again as desired. However, the data from 1st record is still there.
What code I can make in eventhandler to make sure when button1 is clicked the Formview does not contain any data from last entry ?
The formview clear the data from 1st record if I did not set visible/invisible.
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.

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.)
I am trying to add a validation of the textbox.text.length in a FormView and prevent the insertion of being made in case the text length is not compliant (less than four characters).
In the scenario when clicking the submit button an Alert should appear with xxxx warinig text. and the Insert command being prevented.
I am using an ObjectDataSource in my FormView for INSERT.
Data inserts correctly to my backend SQL table, however as i am posting back a success/fail message to the same page, i have noticed that after a successful INSERT if it hit the Refresh button the INSERT is doubled up.
How can i stop a user pressing the Refresh button and doubling the INSERT?
Is there a setting somewhere or can i stop this programmatically within my ObjectDataSource_Inserting method perhaps?
I 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 using a formview to show data, with edit, insert and delete enabled. My problem is with the insert.When i click the insert, the formview changes fine to the template for inserting new data, the problem is it was allowing the user to insert the ID themselves, I have made this readonly, but how would i go about ensuring the ID key is made the next number in line? and that it is printed to this textbox?
I have a detailsview, and I was wondering how I can insert value from a textbox instead of a boundfield value. I am able assign value to textbox in code behind.
I have created a simple dataset with my ObjcetDataSource to my SQL table named Invoices and a new FormView. My form inserts are working 100% correctly, however after some testing i noticed the insert happens again if i hit the refresh button on my browser after an initial insert. I am currently submitting the form back to itself with a success/fail message returned on the page so that the user can keep inserting more records if they choose. This is done in my Inserted behaviour.
In my ObjectDataSource_Inserting code i am setting the values of a date prior to my insert. How do i stop a second INSERT from happening when the user refreshes the browser? I thought it was what IsPostBack was used for? Here is my code:
Up till the moment I can not understand why the "SqlDataSource_NewAccount_Inserting" event of the formview's SqlDataSource is not firing!
The code inside the event handler is not executed, even the debugger does not stop on break points inside the "SqlDataSource_NewAccount_Inserting" function!
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.
I have a formview with insert function into "table1". In that formview i also have a dropdownlist listed with records from "table2". (This dropdown is of course instead of a textbox). get "table1" inserted when one of the field is from a different table?
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)
to force a table width in Formview control templates? I have created a table in the ItemTemplate that works fine but I can't seem to get the table to fill the entire width of the display area. I tried wrapping the entire FormView in a div tag and setting the width to 98% but it didn't work either. Aplogies in advance if this has already been asked. I found a lot of references to GirdView (which didn't help) and nothing helpful r/e FormView except the div tag suggestion.
Here is the code I am using for the ItemTemplate (VS 2008, VB [preferred], in a master page):
I have a dropdownlist that pulls from a datasource. When a name is selected all information drops down to a formview. Once there 3 fields get populated from the dropdownlist and then there is 2 other fields that need user input. Once they hit submit, it should write to a different table in the same DB. I cannot get the fields to populate and write to the DB. Here is my code:
I am having trouble inserting data into the table using dataset..following is my code:
[Code]....
The m_id is a primary key..I want to auto-increament it everytime a data is inserted into the table so I have configured (isIdentity) to Yes and Identity increament to "YES"..I don't know if its right or not..I already added some data manually into the table but now I want to add more data using the above code..but its not working..
