I have a situation where I am accessing a database multiple times and I'm wondering if it is necessary.
I have a GridView with a template column with a hyperlink to "Get Results" and on the RowDataBound event I have it check the batch number against the database and see if results exist and then if they don't, hide the link.
So when viewing the page if there is 20 rows in the gridview it is effectively doing 20 queries.
I was wondering if it is a better idea to query the database once with all "batches" and load it into a datatable, then on the RowDataBound event query the datatable. The only issue I see with this is there is currently 40,000 batches and grows daily.
I have an asp.net application that was working fine on my old dev machine that run XP pro and Access 2007. Although I did have problems getting the ACE OLEDB provider to work and so stuck with the old Jet provider.
I was given a new Windows 7 pro computer that also has Access 2007, I had no problems moving my app to the new dev machine. No problems that is until I had to add a new column to one of my database tables since then my app has been very weird when deleting rows (I am using the OleDbDataAdapter to access the database).
Existing data within the database deletes just fine, however if I add new data and then immediately try to delete it nothing happens, no error, no delete, nothing. This is the weird part; if I navigate away from the page I use to maintain the database (i.e. click my link back to the home page) and then revisit the database maintenance page the new data can be deleted just like old data. I add Response.Redirect() into my code to see if that would work but no, only navigating away from the page and then returning allows me to delete the data I had just added.
This problem did not occur until i added the new column to the database table. There is no problem with my code, the same code worked fine on the old machine and on the new machine right up until i added the new column to the database table. My thoughts are that it must be some combination of using Jet and IIS7. Oh and both the app and the database are on the same machine.
Heres my code:

I am trying to create Web Application using ASP.Net via Visual Studio 2010. The Database that I use is Access, with connection Method OleDb
When using the query "Update" or "Delete", the programs shows no errors, but the data in Access does not change.
While for query "Select" and "Insert", the data is displayed and inserted successfully.
The Following code is the sample query "Delete" that I used..
Code:
Imports System.Data.OleDb
Partial Class frmTEst
Inherits System.Web.UI.Page
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code] ....
Previously I tried a direct query using AccessDataSource, but the result just the same, Update and Delete can't be done. But the Select and Insert can be executed successfully.
Is there any problem with my Access configuration or whether the problem is in the coding itself..?

-7vf- I write a program by c# to check and retrieve data from database
The problrm:I have one table(1), I want to make update for that table(1) that is by compare the one column in table(2) with the right side from one column in table(1), so if there is any similarity it will retrieve the data and if there is no match just it will make the record empty(null) "the data type of retrieving columns: number 'double'", but the problems is:
I try to retrieve 11 columns, 7 of them are empty .the program run with out error ,but it will retrieve some records with full data 11 columns, but some of records has only 5 columns have data and 7 columns are empty (these records when I run the program did not retrive any columns, it give me empty records!!)
this is the code :
while (or.Read())
{ or.GetValues(field); OdbcCommand oc2=null;
[code]....
I want to retrive all data which are empty or null and all data
I currently have a datagrid bound to a table with tens of thousands of records. I display the datagrid using the existing asp.net 2.0. I show ten records at a time.
My problem is whenever I try to access the next page, I gets all the records again from the database and then displays the ones that are required. This is slowing down the app. Is there feature within .net 2.0 which will help me optimize this issue? I cant use third party controls or ajax.
UPDATE
I cant use SQL to get 10 records at a time as well. Without changing any existing business logic or data retrieval, I want to do this.
I've have to delete multiple rows from database in a table . Which is the best way to delete data to optimize performance of sql server as well as asp.net.
View 6 RepliesI have a web portal designed in ASP.NET in which we ask customers to enter the data. On the click of submit button all i have done is, just read the data and called a stored procedure which inserts that into a table. There seems to be a problem in SQL Server 2005 while inserting the data from multiple computers at the same time. We have tested in our lab with three computers, result is that we get the data inserted successfully in only one machine and on the other two machines we get error on page. I have used transactions in the stored procedure and also tried setting the isolation levels to READ_UNCOMMITTED, SERIALIZABLE and SNAPSHOT. Nothing seems to work properly.
View 4 RepliesI have a issue where I am trying to pull some records from an Access 2007 DB that has linked tables from a SQL 2005 Server. When I go to do this the browser IE8 just sits there and does nothing. THe little progress bar at the bottom moves about half way then that is it. It will sit there and show no errors or do anything. I have experience with connecting and manipulating Access and SQL server DB's but not through Access with linked tables from SQL Server. Here is test code below:

This does not produce an error or anything. The browser just sits there and sits there. Is there something I am missing?
