Forms Data Controls :: Inserting/updating To Database Via Checkboxlist?
Jun 16, 2010
I've the user creation form where a user will be created by entering username. Below that is checkboxlist for UserGroup which is binded with the dataset with the all the usergroup. Hence up on entering the username and checkbox selected(as the user can belong to multiple UserGroups).At database end, there are basically 3 tables-
Users(UserID,UserName)
UserToGroup(UserID,GroupID)
Groups(GroupID,GroupName)
So when i click create new user, the UserId along with GroupID(whichever checked) is saved into UserToGroup table.Im relative to this kind of process and hence facing setbacks. Can somebody help in end to end process. From front to DB SP.

Data entered in textboxes is not getting updated in database. In debug mode I see that textbox1 and textbox2 in ItemUpdating event contain the same values as they had before calling ItemUpdating.
Here's my listview control:
[Code]....
What's wrong with updating of text1.Text, text2.Text in ItemUpdating event? Should I use e.NewValues property? If so, how to use it?

Here is the scenerio:I have a radtabstrip (with 2 tabs) at the top of my page followed by radMultiPage control Tab 1 displays pageview 1 which has a gridview showing data from our database and allows for selection or deletion of data tab 2 displays a detailsview when gridview_selectedindexchanged(from tab 1) is fired.Problem... If you select an entry in the gridview it switech the page and the detailsview into editmode (works fine) but if you then click on tab 1 without clicking update or cancel in the detailsview, the data is updated. This is what i don't want as the user has basically abandoned the changes.So what i need is a what to say ... if the detailsview is in edit or insert when the tabstrip is clicked then cancel the insert or update. I tried switching it back to readonly mode but that did not seem to work.

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.
<td
style="width: 454px">
<asp:ListBox
ID="lbox_ConstructionType"
runat="server"
DataSourceID="SqlDataConstructionTypes"
DataTextField="Construction_Type"
DataValueField="Construction_Type"
SelectionMode="Multiple"
Width="144px"></asp:ListBox>
<asp:TextBox
ID="tbox_Ctype"
runat="server"
Text='<%# Bind("ConstructionTypeID") %>'></asp:TextBox></td>

I 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 have seen a project where my friend has used a sqlhelper.dll which make it easy to write code for inserting,Deleting and updating data.
ex:
ds=sqlhelper.ExecuteDataset(con,[StoredProcedure],parameter1,parameter2,...,parametern)
Or
sqlhelper.ExecuteNonQuery(con,[StoredProcedure],parameter1,parameter2,...,parametern)
And he had used a dal(data access layer)...

I have a listview. Inside the EditItemTemplate of this listiview I want to show a Checkboxlist that has 5 checkboxes; S, M, L, XL, XXL. The values (checked / unchecked) of these checkboxes are dependent on a linq query. The linq query just retrieves the values from columns in a table. The columns are S, M, L, XL, XXL (same name as checkboxes for convenience) and all have datatypes bit. What I want now is to be able to databind this query result to this CheckBox list.

I am somewhat new at C# so forgive me if I have something listed wrong. This is what I got:
I am working on a school project designing a car dealership website. I have an inventory list that allows you to edit any car in the inventory. When you click on the edit button it takes you to the edit page and populates the controls with selections from the database. I have an options table that stores the VehicleID and Option ID. When the page loads it fills all the DropDownLists for the vehicle info with the data and selects the correct item according to the database selection but the CheckBoxList does not select the items that are on the Options table. I checked the query in SSMS and it returns the correct data. I have stepped through the method and it works till the "(currentCheckBox != null) if statement. It doesn't throw any errors but it also doesn't select items when the page renders.
I thought it might have been something with the page life cycle since databound controls don't render until the end but the DropDown's I have fill and selects the correct item according to the database.

I have a page where I will insert all the data into the database. The page where I'm having problems is when I select an item from the checkboxlist it only displays one item. The data which is displayed is only the one that was inserted with one selected item from the checkboxlist. The following code is the page I'm using to try to retrieve the data from the database. I am trying to do is when a user selects the first, second, or third, or fourth item. The corresponding data appears in the gridview. In my current code, the record which has one item selected appears. If the user has more than one selected it does not appear. It comes up as empty. Is there a way I can do it?

So I have two tables in my database, Contacts and Addresses:
Contacts : ContactID | AddressID | FirstName | LastName
Addresses: AddressID | Address1 | Address2 | City | State | Zipcode
I have a page where you can add a contact. It contains all the information for a contact and an address for a contact. Here's my code for when you submit the form:
[code]...
Now my main concern is that the address is added successfully, but then an error occurs when I try to save the contact, leaving the address in the database with no contact.
What's the best practice here for rolling back any changes if an error occurs?

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.

My problem is this "I have all the tools, VS 2005, 2008, 2010. I have every book, I have SQL server 2005 and 2008" I have all the tools, but I do not know what tool or technology to use when starting out learning all this. I juat do not know what book teaches what I need to do for something like below.
Here is my question:
I created an .ASPX webform that is to "Submit" to a SQL 2005 database. I gave this form to my DBA, and he has made up a Data Model. Now I have to figure out how to write the ASP.NET code so it will submit to the DB. My first issue is not knowing this:
1. "How do I loop through my CheckBox List", and then insert the values checked into a "Database Table" (Each Checkbox value MUST be a seperate row in the table, the DBA does not want a seperate column for each checkbox value)
2. The database is using stored procedures
3. My third issue is this: "I do not know "where" to put the "code". If you do resond to this,
Summary: I just need shown the code on how to "loop through" the CheckBox List on my form, and insert those values into a database table as seperate rows.

I have a DataList that on Update calls a function "DataList1_UpdateCommand" to update the data
OnUpdateCommand="DataList1_UpdateCommand"
It does not actually update the new value typed in. I placed a debug on the line below, but the text in the "FieldBalance" displays the original value and not the updated value, but the web pages does display what I typed in and not the original.
Dim FieldBalance As TextBox = CType(e.Item.FindControl("txtBalance"), TextBox)

I have a page where I want to let the users vote on displayed items. My customer wants this done with an image and a VOTE FOR THIS link. The link and image are to disappear once the user has voted, and be replaced with the number of votes for that item. I've made the VOTE FOR THIS link a link button. I'm have two problems:
1) the ListView1_ItemCommand code is always excecuted twice, so the vote count is being incremented by two, not one each time someone votes.
2) A page refresh causes the ListView1_ItemCommand code to run (twice) so a page refresh also casts two votes for the item
If it makes a difference, I display one item per page.

I have an updatable Gridview control that I cannot seem to URL encode a textbox in one of the columns. I cannot encode some of the other controls in the row, so the solution from the msdn site doesn't work in my case. I only want to encode the single textbox. However, with the code I have, I don't get any errors, and the database is updated, but the column that is edited becomes empty in the database. Here is what I have in the gridview rowupdating:

I'm just wondering if anyone has come across a good, easy method for updating a SQL Server 2000 DB table using the edit feature in GridView. The catch here is that I need it to encrypt, send to database, then decrypt when the page calls it to be displayed. I have successfully implemented an insert method using FormView with encryption. For some reason, I just can't seem to figure out the edit/update.
