Is it really necessary to display this amount (80,000) records in GridView. Did you ever thing about the web site performance ? Please have a look into it and Try to minimize the records as small as possible. This is just my suggestion.

But I m able to find only records on the selected page, not able to retrieve values from other pages. Selectallpages is working, I can see that by going through pages.

Here is a excellent article by Samir, Maintaining States of Selected CheckBoxes in Different Pages inside the GridView[^]
This will resolve your problem. But please consider the Data amount the that you are showing on page.

Good luck!

Thanks for the link.

I do care for that, but it is the requirement.

Its the admin of the site where site admin wants to see all the values.

I am worried about the performance since I m expecting more than 100,000 users on the site at a time, need to write a perfect caching code and work out with performances.

This count will go above 100,000 in 3-4 days.

That's correct. But why you are not giving some search criteria, based on that display the data.

Reading all other posts, I understand you care about performance. So don't use the built-in gridview paging. It just loads all the data at the beginning and reloads it when page index changes which will be huge performance issue. As a remedy, use custom paging.

I tried looping through gridview rows but its gives values only of current page.

Loop through the data source. Data source will have all the values.

Please help any VB 2008 / asp.net 3.5 guru

I used dropdown list box SQL Server , list view, Pager … its working fine see the link below
http://www.tharjuma.com/anquran.aspx

The problem I’m facing is See the program …. For Example
If the I am selecting the Sura No 6. And press SHOW button , It will jump to the page No : 177 as the Database and program as I did

The same way if I choose Sura No 18. And press SHOW button , It will jump to the page No : 408 as the Database and program as I did .

But if I pressed Next/Last button in the pager its working ….but after that if select and Drop down list as mentioned on the same way it will not show right page. It requires the “First“ PAGE button of PAGER button to be pressed once then only it will be shown properly

How to rectify this? I think we need to reset the Pager every time when we click the Dropdown list? Could anyone guide me?

Here is one way...

create a Serverimage folder in your web application

Public string GetServerImagePath()<br />
   {<br />
       return System.Web.HttpContext.Current.Request.PhysicalApplicationPath + "Serverimage\\";<br />
   }

qn123 wrote:
the following code for the physical path..it is working fine...

File1.PostedFile.SaveAs(Server.MapPath(".\\" + StrFileName));

and while upload

fUpload.PostedFile.SaveAs(GetServerImagePath()+ "StrFileName");

Note : You have to give write permission to every one on that image folder

custom pagging with dataset and updatepannel

bikash pattanayak13-Mar-09 20:23

13-Mar-09 20:23

dear friends,

I have a gridview and it is within a updatepannel.I want to impliment custom pagging for this gridview and there are certain conditions for custom pagging as per my application requirement and these are as follows:
1. I run a SP and get the data and storeed in a dataset.say 100000 records i got and store in the dataset.
2. Now when I select the pageID from a dropdownlist it should not hit the database again inspite of this it should took out only 10 records at a time from the dataset which was already filled and stored in the dataset when the page is loaded firsttime.
Here I am facing 2 major problems
1. since i am using updatepannel pagging is very slow and i cann't remove the updatepannel in this moment due to application requirement.
2. Cannot findout the proper code in this sinarion for handle custom pagging in codebehind using dataset,dataview or datatable.Because I cannot use a SP for pagging due to application requirement so only I hv to handle it in codebehind.

Hi Bikash,
You have to look on Sys.WebForms.PageRequestManager class. Check the MSDN Ref^[^]
Even, I went through the similar problem for maintaining the Grid Scroll Position inside the update Panel. I have written one article on this, Hope this will help you, MMaintain GridView Scroll Position and Header Inside Update Panel[^]
