Web Forms :: Force A Page Break From Server Side Code?
Mar 18, 2010
I'm building an application that creates bar code images based on the number of selected rows in a GridView. It counts out 6 bar codes and the corresponding labels, and then it needs to force a page break when my counter hits "6".
How do you force a page break from your server side (VB page-behind) code in ASP.NET?
Can you change the pagestyle from the code-behind? I wanted to try : "pagestyle = "page-break-before:always" - but it was not an option in the intelisense menu...

So I have a repeater control that lists a bunch of information for each staff member...one after another. Problem is when I try to print this list I have staff records starting out in the middle of the page. I would like to solve this issue by forcing a page break at the beginning or end of each record/repeater item. How can I accomplish this?
<body>
<form>
<asp:repeater>
<itemtemplate>
<table>
<bunch of html>
</bunch of html>
</table>
</itemtemplate>
</asp:repeater>
</form>
</body>

One of my apps is to document aircraft inspection at mil sites. The discrepancy report for any one tail number can be many pages long. The description of the discrepancy in a gridview cell can be several lines. Therefore when the gridview hits the bottom of the physical page, the print spooler frequently splits the gridview row leaving part on one page and the rest at the top of the following page. I have done my due-diligence in research before posting but maybe I'm using the wrong words. I found something on CodeProject but it is too complicated for me. Does anyone have a simple solution? I use C# and am not very sharp with Java script.

I have a dropdownlist that I already have manually databinding. I currently get the data, loop through each item, and depending on values in the item, change the css for the individual ListItem.
For example:
foreach (Site mySite in myList)
{
ListItem li = new ListItem(mySite.FullAddress, mySite.Id.ToString());
if (mySite.DisabledFlg)
{
li.Attributes.Add("style", "color:#999");
}
this.Items.Add(li);
}
I'm trying to force the text in the listitem to break at certain points. The string that I retrieve from the datasource currently has a " " everywhere where there should be a line break. This works fine for display in a normal textbox, but it doesn't work on the listitem. I've tried replacing the " " with a "<br>" but when I do that, it just displays <br> in the listem along with the rest of the text. I've tried wrapping the listitem contents in a "div" with a width attribute, but it also just display the "div" tag literally in the ListItem text. I've also tried adding the following to the ListItem attributes at bind:
li.Attributes.Add("width", "100px");
But that hasn't resulted in any change either.
I've seen custom drop down list controls that have multiline listitems in them.

I was wondering if there is any way to always run some server side code when a user leaves a page in ASP.NET. The page Unload event is no good because that doesn't get called if someone clicks on a link. Ideally I'd also like the code to run even if the user closes the browser.

I need to do stuff after my page is rendered in the browser. In detail, i need to send email/sms and other non-browser related stuff, but the operation takes time, and i dont want my visitors waiting 5-8s for the success message.I have tried putting the "After Rendering Code" in the page Unload event. That seems to work - but only on localhost. It does not work on our production server.So i figgured, maybe this is some IIS setting? I've also read that it's up to the browser, if it will show th epage after rendering is complete - or wait for the whole package to end.So i tried to end the package with Response.end before my "A-R-C", but that just killed it.

The scenario is this. I have a long page that has a scroll bar. I'm us an Ajax ModalPopupExtender and that too is very long and has a scroll bar.
The problem I'm seeing is that in IE when a user scrolls the modal popup window, when it reaches the bottom it also scrolls to main window which has a really ugly user experience.
So what I want to do is, through server side code, I want to dynamically change the body css overflow from auto to hidden and I can't seem to find a way to make that happen. I've tried a number of approaches and none of them seem to work.
<body style="overflow:hidden;">

I am using Ajax's EnablePageMethods way to call server side code using javascript. The problem is that in IE8 the page automatically refreshes after the ajax call has been completed i.e. the server side function has been executed successfully. I want the same to happen with Chrome and Firefox but it doesnt refresh the page once the server side function has been executed.
I am using this way to call server side code from Javascript -- [URL]
this is the javascript function:
[code]...
this is where i am calling the javascript event:
<a href='myPageName.aspx' onclick='javascript:editNode(1);return false;'>Delete</a>

in a form i have a buttoin, when click both OnclientClick and postback should happen. on clicking the "Email" button a client side "mailto" tag should do the work and pull a new message window on the client's machine.
whereas, the email addresses should be invoked by the post back. so , when clicking the button the server side post should happen and on return the client side script should be invokded with the values read during post back, and populate all the email addresses.
i need know how to first do a server hit take the values and then execute the client script with those values without using AJAX

Executing Server side code using Javascript. Here is the solution.In the Asp.net forums, I often see the question asked, "Can I call server-side code from the client/JavaScript?" Almost invariably, the responses given are "No, the client cannot access the server," or "You can only use WebMethods or PageMethods." The first response is not entirely correct, and unfortunately, WebMethods and PageMethods are static methods and therefore have no way to directly access the page.This is why I present to you the following "hack". I call it a hack because there really should be some way built into the ASP.NET AJAX Extensions that allow this approach directly. Instead, it relies on using controls in a manner that they aren't necessarily intended in order to obtain the desired result. But this "hack" does have a redeeming quality—it's incredibly easy.The Code:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default2.aspx.vb" Inherits="Default2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

I know that I can receive an javascript object from the server via ASP.NET AJAX using Json. But I am not sure how can I send an javascript object from my client-side javascript to my server-side code. And if I can, how can I extract this object in my server-side code and access its members?

Suppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).
What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).

I am working on page where data will update in every 10 second by scraping data from other Stock website. So basically page is displaying stock data which update in every 10 seconds. I am using update panel and timer control. Now problem is that if 100 users open the webpage 100 request go server in each 10 seconds. I want to implement Cache on page where Cache version of page serves to other user. I am using <%@ OutputCache Duration="10" VaryByControl="Timer1" %> but when event occur code run intends of delivering Cache version of page. What I am doing for test.
1) Open page in different browser in local
2) Checking browser type using code
Dim s As String = ""
With Request.Browser
s &= "IP = " & HttpContext.Current.Request.UserHostAddress & vbCrLf
s &= "Browser Name = " & .Browser & vbCrLf
End With
Label1.Text = s
if page first open in IE then if I again open in firefox it shows browser type IE but after 10 sec interval it will update type to firefox. So I want to display Cache data only instead of executing server side code for each different browser.

I have to access my html control and get its value from my server-side code. Is there anybody who could suggest how I could do it?
My html control is very simple: <input type=text>
But the thing is: I can't make it <input type=text runat=server> cause in this case my jquery functionality (datepicker) does not work.
