Forms Data Controls :: Check Duplicate While Inserting Record From Texbox?
Aug 25, 2010
On inserting record, I want to check that for example if a user enters a telephone number for any record is already in the database then it should validate that the number already exists in table and you cannot enter a duplicate value.
Then if user will provide some other telephone number then he allows to insert record.
For insertion of record I used ObjectdataSource.
User will enter telephone number in a simple textbox.
I may want to inform that I am working in asp.net2.0 and also not allowed to use any third party control or ajaxtoolkit.

I have a formview and inside it there are two textboxes taking integer as input.I put a condition that if both textboxes are empty then user should be notified that "Please put value in any one of the textbox".It is working very fine.From database side DBA checked that if user input any integer value in any one of the two textboxes and if it is already found in database then there is no insertion.The problem is that everything is working fine and i checked in the database that the record is also not inerting due to duplicate check but user is getting message that "Record inserted successfully."How to stop this message and how to notify user that you have entered duplicate value and transaction should also not been done. Means all inputs should be there rather than clearing textboxes that could be done when "Record Inserted."

I have a gridview with delete buttons for each record (I've used AccessDataSource). I have loaded the data in and have many duplicate records.
I just want to use the delete button delete each duplicate record while remains many duplicate records. For example:
I used the following query to load in duplicate records:
SELECT * FROM TableA WHERE ([ControlA] IN (SELECT [ControlA] FROM TableA GROUP BY [ControlA] HAVING (COUNT [ControlA]) > 1)))
ID ControlA PIN# FaceValue Date
delete 76637 128232 1234 5 6/4/2006
delete 72722 128232 1234 5 6/4/2006
delete 76638 234567 2345 10 7/3/2006
delete 72723 234567 2345 10 7/3/2006
What is the query to delete single duplicate record instead of deleting all duplicate 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 having trouble changing page numbers on my gridview after deleting a record if the deletion of the record causes there to be no more records on that page. Currently I have a form below the gridview that adds a record to the datasource of the gridview.
[Code]....
Code behind stuff:
[Code]....
Now with this code above, if I insert a new record using the form below the gridview, it will reload and go to the new page if the insertion causes the record to appear on a new page, however when I delete that record, thus causing nothing to be on that page, the gridview visually just dissappears. I've got the gridview bound by a linqdatasource control, and on the page_load function I only databind if the page is not a postback.

I have a GridView1 With Paging allowed, PageSize = 10. And a Nested GridView2. The INSERT function on nested GridView2 works well until the number of record is 10.
On inserting the 11th record, the GridView1 is recorded normally in page 2 of 2. The Nested GridView2 does not fired properly. it appears empty on the 11th record (page 2 of 2), but instead add its record on the last recorded ID on page 1 of 2.
When I remove the paging, everything works well.
How to resolve the paging issue with Nested GridView on "INSERT" record?

I would like to check if a particular value already exist in the database Gidview row. If the value already exist, tell the user that he has already entered the record and don't save. otherwise save the record. In my case I want to check the "Random number".
<asp:TextBox ID="txtRandomNumber" runat="server"></asp:TextBox>
Maybe it could be done with a foreach loop statement.

I now want to insert a number records into the database using the following:
Dim insID As Object = e.Command.Parameters("@insID").Value ' gets out latest ID
Dim ordernumber As String = "CX" & insID.ToString & DateTime.Now.DayOfYear.ToString
sqlOrders.InsertParameters("orderNumber").DefaultValue = ordernumber
sqlOrders.InsertParameters("orderDate").DefaultValue = DateTime.Now
sqlOrders.InsertParameters("customerID").DefaultValue = userID
sqlOrders.InsertParameters("productID").DefaultValue = productID
sqlOrders.InsertParameters("totalPrice").DefaultValue = "0.00"
sqlOrders.InsertParameters("status").DefaultValue = "Paid"
I currently have this code in the SQLDataSource_Inserting sub but the first line only works once the record is inserted. How can i get the ID out as im inserting the parameters?
