It's better if you load the database in the Cache when application starts and then use the cached database.It'll help in better performance

I believe you are using paging feature for displaying 2000 rows in grid view.
Transfer 2000 rows across the network will take long time and application becomes very slow.
Instead of that you can write a stored procedure, which will fetch only those rows which are supposed to display on a particular page ( suppose if page size is 20 and User clicks on 3rd page your stored procedure should fetch the rows from 41 to 60 records)
you can find variety of stored procedures on the net for doing this, just Google.

Hi...
First I would like to know whether you need to get the files from the directory in the local system only or you would like to upload the files as well.
If you want to get the files from the directory we can use Directory.GetFiles() method.
GO through the following code.
GridView1.DataSource = Directory.GetFiles("c:\\Tempu\\Upload", "*.doc");
GridView1.DataBind();
Please let me know if it serves your question.
Regards
Raj.

In your Question you have this
i am developing an application in aSP.net using C#, in which i want to store the files path into access database
I wanted to Answer you , but when i saw this again
then i want to open this file when user clicks on the particular link
You consused me there. Well i dont know what you are doing but you can save the File path in the Access database like any other record but by keeping in mind that it can be long text. but mybe you can explin clearly what you want to achieve.
Thank you

Hi,
First you should increase your data type length bcoz file path may be very lenthy and then u bind file like other field, and check ur file is having correct path with file name when it is inserted.
|
|
|
|
|
As u said, when user click on the link it wont open,remember only the path is there in database .U must store the file in database,then only it will happen. And if u r storing the full path,then it is easy to get the path as cell value.Then u can open it.Make that field in gridview a template and try

Hi all,
I have developed my web site using Visual Studio 2008 and Framework 3.5, but the web server where I have registered contains only framwork 2.0, I have created the web site, that interacts with class lib to fetch and store data from and to database. So, my question is if i compail all this class lib in 2008 environemt and reconstruct a new site using the 2005, will all these class lib will work with the new site in 2005 and Framework 2008?
When i tried to convert the project to Framework 2.0 by Right clicking the Project->and changed the Frame work from 3.5 to 2.0 from the drop down, i got more erros with the reversing of List<> ASSEMBLY REFERENCE MISSING, some of the namespace missing errors. How to handel this suitaion and solve the issue with in less time
Else is there any good solution with this, insted of installing Framework 3.5 in server,
Please suggest me
Thanks in advance

Obviously, if you get those errors, the server will, too. The best thing is in future to establish your target framework before you start. For now, you need to fix those errors.

Hi,
Try setting the "EnableViewStateMac" property of the <%@Page...%> attribute to False.

Hi Every body...,
i have problem with CSV.How to Coverting data in a table to CSV file.
(i am using Sql2005 and Vs2005 asp.net ajax,C#)
Please Help Me.........,

The fact that you mention AJAX makes me worry that you don't understand any of hte things you are using.
you get your data from SQL Server, and you write it to a file, with a comma between each value and a new line between each line. It's really that simple. Which bit are you stuck on ?

1) Using a datareader to directly read the data and write the file yourself
2) Using a DataTable/DataAdapter combination to load the data and write the file yourself
3) Using Sql's built-in export feature to write the file
4) Using Sql's ability to output Xml and using an XSL Transformation to write the file
There, that should give you some google fodder.
Ive probably missed a few.

use
Response.Write(String.Format("{0:MM/dd/yyyy}", DateTime.Now()));
The miracle is this--the more we share, the more we have.
