Asp.net gridview dynamic change pagesize not work on the last page.
I have added one dropdownlist in the pager of gridview and add event of selectedIndexChanged with the DropDownList.
Changing pagesize is working except the last page

There is a gridview and I am binding some records to it. in my database there are 4 records but gridview always shows 3 records. Even I have given PageSize 10.
View 4 RepliesGridView 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 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?

Using VS2005, VB code behind,
I am extending the GridView control to include a custom pager for a custom paging scheme (only one page returned from the database at a time rather than all records). In my testing a discovered an issue - on my last page of data, the GridView's rows property always returns a collection of PageSize page, rather than the actual number of records on the page, with non-data fill records being empty rows.
For example, suppose I have 23 records in my database. Assuming a PageSize of 10, when I page to the last page of data the gridview it properly displays the last 3 recrods - but when I handle the GridView's CommandName="Select" event the GridView's Rows collection contains 10 records, the last seven of which are empty.
I set a break point in just before I call GridView.DataBind and verified that the DataTable used as the DataSource for the last page of data does in fact only contain the 3 expected records. But when I set a breakpoint on the Sub that handles the "Select" GridView command, the GridView.rows collection contains 10 records, the last 7 of which are empty.
This post[URL] and comments make note of the issue but the solution prescribed by the author does not seem to work.
Attached are some snippets of my extended GridView and the two methods from my page where I mentioned setting breakpoints above.

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.
in my webapplication i create a pdf document based on a pdf template which paegsize is Iso C6 (envelope ).
The documet is returned to the client in the response output stream .
If i choose to open the document (and print it) , i have the printer pagesize automatically set to the a4 pagesize;
This cause a side effect : the text printed on the envelope is not in the right position because the printer pagesize is different (on a a4 paper the envelope is centered on the paper!!!).
Can i set the printer pagesize with itextsharp?
I have Template fields configured for Gridview. The gridview is using an objectdatabsource to bind itself. I have the gridview configured to use Templatefields which then contain tables to display the information. This works fine.
My question is, is it possible to change the text of the label if certain criteria is reached. If "NumberOfDwellings" is 1 then change the label to read, "1 Dwelling". Where-as if NumberOfDwellings has more than one then it's "3 Dwellings".
<asp:Label ID="lbl_NumberOfDwellings" runat="server" Text='<%# Eval("NumberOfDwellings") & " Dwelling(s)" %> '></asp:Label>

So I have a GridView control with autogenerated column set to true, it also has autogenerated Edit and Delete buttons, sorting and paging, and also I am binding this same gridview to multiple data sources at runtime. All is working well.
Now I am adding a dynamically generated footer row at runtime. This footer row will allow users to add new record regardless which data source it binds to. So it is working as well except there's a small bug I couldn't figure out why. It's when I navigate to the last page of the gridview, if the rows on the last page is less than the page size, for example, I have page size 10 and the rows in last page is 9, then when I click the 'Add' linkbutton, the Add event does not fire, instead, it fill the last page with additional blank rows, that means if the last page has 5 rows, it will fill 5 blank rows below, if it has 9 rows, it will fill 1 blank row below. Then if you click the add again, it will work. If the last page already has 10 rows then, it works just fine.
Below is the code I used to dynamically add footer row:

I have a GridView in an update panel that is bound (in code-behind) to a business layer object. The first time this page is accessed, Editing, Deleting, Updating, etc. work fine. However, if I click my browser's refresh button, the functionality of the edit, delete, etc link buttons is gone. They do nothing.

If there's a better way to accomplish what I'm attempting I haven't found it yet. That being said, I have create a gridview like the one here,[URL]And with some minor tweaking it working great for all my fields, checkboxes, etc. The issue is my last column is another gridview, and I'd like it to function the same. that is, a dynamic gridview inside of a dynamic gridview. I get that I have to create it initially with null values or it won't show up. I guess what I'm having trouble figuring out is instead of go will null data in the parent gridviews column, do I place my blank child gridview. Do I create and bind the child gridview first, or second. Generally just not sure. Also, as far as storing the data from the child gridview goes, will each one need it's own datatable?

So my problem is as followes:
i have a gridview in another gridview (gv2 inside gv1).
in codebehind, at pageload i have: [Code]....
witch gives me a number of total records in the gv2 to a label. something like a coment number label.
my problem occures when i press the page button (allowpaging = true) on the first gridview. it acts kinda like this:
it makes the second gridview.visible = true; doest string the number of rows, and the label.text = "";
i've tried to make a code like this:
if (Ispostback)
{
gridview1.databind();
foreach ...etc..
}
else
{
foreach ....etc...
}
Also the gridview 1 and 2 the datasource is an SqlDataSource.
but that didnt work . also tried some things in pageindexchanged and pageindexchanging but still no efect :(. and also tried with enableviewstate = false / true on both gridviews with diferent combinations, but still no luck.
the code works only when i have allowpaging = false, or when im on the first page of the gridview (for the first time) is that the number of coments is pasted into the label.
I need your help / guidence for doing custom paging in c#, through sqlserver. so that i can have data in dataset/datatable according to the pagesize given, not all the data in dataset. some code /url .......with full discrption if possible.

View 5 RepliesI have this gridview, what I wanted to do is that when the page_load or when the page index changed when the user clicked "Next or Previous" the label change with the gridview. The label and the textbox get the information from the gridview row. It's working but it's alway lagging behind the changed gridview page. Ex: When I click next nothing happen, when I click previous the label changed to the info on the "next" page. O_0This is the code behind.

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 need to get the selected Pagesize value from the gridview pager.
