Web Forms :: Retain Control State And Values From WebPage Displayed In Iframe In A MasterPage
Dec 29, 2010
I have a MasterPage and a ContentPage. On the ContentPage I Similated a TabControl by using a Menu and an IFrame. When the menu item is seleceted it loads in the appropriate WebPage into the IFrame. Now... on one of the WebPages I am creating dynamic controls on Page_Load. But when I refresh or switch menu (Simulated TabControl) back and forth, then I lose my controls and values.

My Client has an application that is built in ASP.NET (c#) that makes use of a lot of ExtJS controls.
I need to enable the application to save every thing on the entry screen to a temporary storage mechanism and when necessary restore it.
The scenorio is the user has captured some data to a specific screen but is unable to continue and then there session expires.

In my application, session value automatically set into null.In certain workflow only it will set as null (Normally It's able to access value). Example, at the time of login, I will set session values. While, user deleting some entries from drop down list of specifc page,client script will show message like selected entry deleted. After that, flow point will move to master page. There I have to access session variables. It's getting null value. I tried to debug with Quick watch, at the pageload of master page only value set into null (automatically).

I have a masterpage that, for the sake of simplicity looks like this:
masterpage.master-
<div><asp:TextBox id="txtboxsearch" runat="server" /><asp:Button id="button1" runat="server" PostBackUrl="~/nextpage.aspx"></div>
<p>
<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</p>
What i am trying to do is read the value from the search textbox from the nextpage.aspx. When i hardwire a text value to the txtboxsearch, i can read it using the page.previouspage property in the code-behind of nextpage.aspx. But when leave it empty so it will dynamically extract whatever value that's typed there, it doesn't read it. I am sort of understand why it is failing but can't fix it. I have gone through: [URL]

I have created a customized GridView Control.
I have created a property called as IsEntryGrid. Which is boolean. If it is true then it is assumed that it will be a grid where dataentry is possible from footer controls. Controls in footer are created dynamically. My problem is that when i m pressing ok image button control state is not maintained.
eg. In my footer say there is a text box for field OrganicationCode. I enter Org Code as M01 and if i press enter, i m not getting that back in my page event..
my code to create grid footer....

I am using framework 4 and VS 2010 and have two iframes that loads two web pages on load. I enabled scrolling and set properties of iframe this way:
<iframe src="http://iis/app1/Default_display.aspx" runat="server" width="100%"
height="900" id="I22"
name="I22" marginheight="0" marginwidth="0" scrolling="yes"
style="overflow: scroll" >
<p>Your browser does not support iframes.</p>
</iframe>
My problem is that when page loads I have scroll bars on iframe but when I scroll the page is not complete bottom and right part are not displaying at all I just cant see it. If there are any controls in that unvisible part of page they are moved and everything looks bit messy. How can I display 100%, complete page (like when it is open in new window) in iframe with scroll bars?

I am having weird display issues using the jQuery dialog with an iframe in Firefox and IE8.
I have tested the page itself outside of the iframe and the problems are not reproduced, only when inside of the jQuery dialog.
Issue,image actual size: 300x225 image display size: 400x300
JS Code - Parent Page
$(document).ready(function() {
var img = $('.photoLink');
var imgSrc = img.attr('src'); [code]....
The class of the image is set dynamically based on image dimensions.
The image path is set in the code behind, no styling or resizing done.
The images are resized upon upload to be no larger than 300x300.
Display is correct in Chrome and Safari, but in IE and FF for some reason it enlarges the image.

I'm curently developing web application which uses standard form authorization and, of course, server session objects (quite classic app). Now I'm developing client side component, which base functionality is to allow users to acquire tiif/jpg/pdf document from scanner (client side) and send it to server. Because of scan complexity and need for very user friendly interface i decided to implement Activex object (object written in .net 2.0). Until now all was ok, so I have got activex which succesfully registers and scan documents on client - but i cannot manage with sending files to server.
My concept of sending files was like that:
- preparing Upload.aspx web page wich is used for reciving files sended by POST method and saving files in database (of course to proper save in database i need some current user context information) - in ActiveX i decided to use System.Net.HttpWebRequest object to prepare and send data the problem was third point:
- i thought that in-proc activex object would "derive" web session form web page activex is placed on - but i was wrong (or i made it wrong). Whenever i send request form Activex, in response i got login.aspx page - so it looks that new session is created and new authorization is needed.
I was trying to pass to my Activex values stored in "ASP.Net_SessionId" and ".ASPXAUTH" cookies, as i found that these are the values identifying session and athorized user - but with no luck.
I think, that becaause HTTP is stateless protocol all information needed to "connect to/share" existing session on IIS server need to be included in request data, so there must be way to add these information to request sended from my activex.
I would be very grateful, if someone could provide me information what should i add (headres/cookies/etc... ?) to my request data so it could share session from "parent" web page.

In web config file I have add key values specified.
In the formview I have labels on edit , item and insert mode that I want to display all the time by getting those values from web config. I'm able to do that with no problem but when I change the modes between edit to insert or item view, I lose those label values until I hit the "select" twice from the Gridview, those values re-appear. Below is the snippet of the code. What do I need to do to retain the category values all the time?

We are setting session variables in the login page with all user details.And in all subsequent pages we check this session variable.This check is done in the page load of master page.As the number of users increased am getting error with these session variables.This session variable is returning me "nothing" when I check and the user is redirected to logout page.Interesting thing is that this is not happening always.
