Forms Data Controls :: To Force GridView Download Data According To The Pagesize Without Passing Limit In Sql?
Nov 17, 2010
I have some doubt about GridView PageSize, for the example if my table have more than 100000 rows and i set PageSize=50, i can see GridView trying to download whole 100000 rows and display only 50 records with pagewise.
In this case my application getting very slow.
Is there anyway to force GridView download data according to the pagesiz without passing limit in sql?

GridView bound to a SqlDataSource. GridView.AllowPaging is True. In one of the ItemTemplates I have a LinkButton with a OnClick event.Have a DropDownList for changing GridView.PageSize - done in Page_LoadEverything in of-course in an UpdatePanel.
The whole thing work fine (we are in test fase). The problem is that the LinkButton OnClick event is only being attached to the initial "PageSize" amount of elements. Fx. if I sat PageSize=15 in the <asp:GridView> then change the page size to say 30 from the DropDownList, the page size changes but only the first 15 LinkButtons fire the OnClick event when clicked.
I've tried to do the following:
Attached an "onchange" javascript client event for saving the selected value in a <asp:HiddenField> before postback. Problem here is that the HiddenField value is then only available on Page_Load. By then it's too late to set the new page size on the GridView because the attachemnt of events to the LinkButtons have allready happened - of-course only to the first 15 elements.Then I tried to drop the PageSize=15 in the <asp:GridView> and only sat it in the Page_load. The idea was that with no paging all the Linkbuttons will get treated evenly. That worked, but when I change the GridView page size and click fx. on LinkButton 25, the Click event forks fine but the GridView page size resets to the initial value (15) - no good.
how I can get all the LinkButtons to have their event working, even after I change GridView page size?

I have developed a application using Visual Studio 2008 and SQLServer 2008. I have a page called "Billing Center" where i need to display more than 500 records in a gridview and the gridview has sorting enabled. If i limit the page size upto 10 only the gridview performs well but user requirement is to view atleast 500 records at once which is slowing down the gridview record retrieval process.
I am using the following C# code in code behind to sorting, paging and retrieval . Please guide me what am i doing wrong in this code and how to make it work with large data set.

I've been working through the ASP.NET Security Tutorial 12, seen here:
http://www.asp.net/%28S%28pdfrohu0ajmwt445fanvj2r3%29%29/learn/security/tutorial-12-cs.aspx
Part of this tutorial entails setting up a GridView which is bound to the collection of UserAccounts, and then enabling paging on the GridView. There are the usual four links for First, Prev, Next, and Last pages, which should work because I have twelve users defined, and the pagesize of my GridView set to 5. I've set up the code to enable or disable the paging links depending on what section of the entire UserGrid is currently visible.
So when I first run the website and go to the ManageUsers.aspx page, I would expect to see only the first five users in my collection. But it shows all twelve.
I must have overlooked something, but I can't find it in the text and examples.

I'm sure it was discussed hundred of times, but maybe this time will elucidate some new points )
The question is: do I need to limit number of selected rows in data source for GridView?
When I use paging in GridView does limiting selected rows make GridView work faster?
Now I use ObjectDataSource with Linq in functions.
[Code]....
Does this make sense or I can just use LinqDataSource without thinking of selected rows?

When (in what event) is the best time to set PageSize for the ListView's DataPager? I have tried every event on the ListView and either it does not work (i.e., reverts to the default 10) or I get a CRASH of some sort (mostly error 12002) - but that's a different story.

when updating a decimal field in a GridView all is fine when using e.g. "2.3" ("." to separate the fraction!)
However, when using "2,3" I get e formatstring exception!
I tried "regularExpressionValidator/RequiredFieldvalidator" but did not succeed! Tried also with FormatString like {0:n}.....
Questions:
is this controllable by "Culture / UICulture" in web.config (played with it without success!
How do I best check for correct input i.e. force "." as separator
Can I use the "DataFormatString" property for the appropriate GridView field (like {0:n}) ......

I have a gridview and I have an edit template for one control. I have a drop down box in this edit template so that you can select a value from it and then when you hit 'Update' the value from the drop down box is committed to the updated record. Unfortunately when I do hit the update button I get a fault that the "Status" field cannot be null.
Here is the code that picks the value from the drop down value and assigns it to the new values list:

I have gridview that lists a column of hyperlinked names. A procedure is passed to get the data for the gridview. I am also pulling an ID to use once the name is clicked. Once clicked the ID is used in another procedure to populate a formview. I am having a problem getting the ID to be associated to each hyperlink name in the column and figuring out how I am going to grab the ID from the asp:hyperlinkfield and then assigning it a variable to use elsewhere. Right now I trying to create a datarow with a new attribute.
