i am using window.opener.location.href = window.opener.location.href; to refresh a page from another page
and it s working fine but i need to preserve state because i am loosing any ViewState on the first page when i do this. It will be as if the user typed in the url in the browser again instead of hitting refresh.
I have a very simple nav menu of 5 imagebuttons: home, bios, areas, resources, contact.As a user rolls OVER the imagebuttons, the imagebutton change to a black background. As a user rolls OFF the imagebutton, it reverts to the original image. If a user clicks on a imagebutton (ie contact), I programmatically set it to the rollover with black background. The goal is to: if a user clicks on an imagebutton, then continue to show that imagebutton in the rollover state so the user can tell what page they are on. I have all this working just fine.My problem is this: If the user then rolls OFF one of the selected imagebuttons for the page they are on, then the javascript overrides the code-behind and changes the image to the original image. The menu then no longer shows the page that the user is on.What do I need to do to keep the rollover state active if the button is clicked and then rolled over later? For example, a user clicks on Contact, then moves the mouse off of that button. I want the imagebutton for Contact to stay in the rollover state.aspx.cs:
if (!IsPostBack)
{
ImageButtonWelcome.Attributes.Add("onmouseover", "this.src='images/rollover/images/welcome.jpg'");

I am having a ASP.net application it having three pages ,page 1,page 2,page 3,when the user navigating between this pages I want to maintain the view state in page level after postbacks(i.e.) .If a user visits page 3, passing some query loads some data .then he moves to page 1 doing some entries .after that he once again moves to page 3 now I want to display the data previously available at the time he moves to page 1, same
way I want to do to my three pages up to the user logging out.
I'm having troubles remembering how to grab the list view's state, or page, so that when you leave the list, you can return to the list view page you left on. I have a data pager, and I have hyplerlinks for items in the list view that take you to a file upload or file delete page, and then returns to the list view. It returns to the list view's initial state (first page).
View 1 RepliesHere is what I want to do: I have a local site in which I want to display data from a remote site
Lets say: I want to display data of http://www.abc.com/Default.aspx on my localhost
Now Default.aspx requires some post-data which it sends to itself. Thus the __viewstate and __eventvalidation are posted back to it by itself. I want to directly post the data to Default.aspx from localhost without opening Default.aspx and display the Default.aspx's response on my localhost.
The WebApp on http://www.abc.com is configured for __eventvalidation i.e. I cannot post-data to it from my localhost without getting a __viewstate from it. I also have to post the current __viewstate of http://www.abc.com/Default.aspx to itself
Recently I had migrated my ASP.net 1.1 based application from a IIS5.1 based platform to a IIS 6.0 based Platform.The new platform has 4 nodes with a load balancer.
One of the page of my application, which is perhaps the heaviest one in terms of form components like textboxes, dropdown is not behaving properly.Some times the users only get a "Blank White Screen" and some time they get a "Invalid ViewState" , Invalid length for a Base-64 char array.
Based on the KB
http://support.microsoft.com/kb/831150 I understand that the view state is getting truncated.
I had been facing this issue since we migrated to the new platform and the application was working perfectly fine on the old platform.
How can we pass the View State properties from one ASP.NET page to another in ASP.NET?

View 2 RepliesI have a page with is basically a few Gridviews that I want to email to some users. The Gridviews are connected to sqldatacontrols. I create the select statements in the code behind. This all works fine.
To email the page I read the page into a streamreader and then creates an email and sends it. So when I get the email the Gridviews show no data.
I stepped through my code and found that the issue is with a variable. The Select statement has a few parameters one of which comes from a profile variable. When the page is read the profile variable is empty. I tried it as a session variable and that fails as well so my question is if I cannot use profile variables or session variables what other way is there to save this data?
In VB I can place module level variables so that say when a form loaded and I wanted to save a variable I would load the module variable which made it available to any form in the project but I assume that I cannot do the same in VB.net asp.Net? On the first page load the variable is available I just have to figure out a way to save it to pull out again when the page posts back.

View 3 RepliesI have two radio button list:
*1* report views -- 4 options -- NOT in updatepanel
*2* pagination views -- 2 options -- IS in updatepanel
The situation goes as follows: Refresh WORKS in default setting but when I select *2* radio button options and refresh the page renders the state that the (1) was entered in.
Example: () are the radio buttons
Report Viewing: () (x) () () Pagination View: (x) () REFRESH works!
Report Viewing: () (x) () () Pagination View: () (x) REFRESH fails to display Report Viewing: () (x) () () Pagination View: (x) ()
Report Viewing: () (x) () () Pagination View: (x) () REFRESH works!
OR: () are the radio buttons
Report Viewing: () () (x) () Pagination View: () (x) REFRESH works
Report Viewing: () () (x) () Pagination View: (x) () REFRESH fails to display Report Viewing: () (x) () () Pagination View: () (x)
Report Viewing: () () (x) () Pagination View: () (x) REFRESH works
I am using the session variable to hold the Pagination Viewing option but during page states, I've noticed that when a 2nd option is selected of *2* radio buttons (doesn't matter of 1st or 2nd option was initially selected) that during debugging mode the step over corrects the issue but not the right table viewing. Upon entering Page_Init selection selection index of radio button list returns to 1st option.

View 9 RepliesI have a grid view with a nested text box in it.I would like to turn view state off but the fact of the matter is when data is posted,the text boxes inside the gridview aren't available (there are no rows in the gridview on postback). Control's information is not stored in the View State (for things like selected value and .text etc.):Control state,introduced in ASP.NET version 2.0, is similar to view state but functionally independent of view state.However,control state cannot be disabled. Control state is designed for storing a control's essential data (such as a pager control's page number) that must be available on postback to enable the control to function even when view state has been disabled.
