AJAX :: Page Refresh Clears RadioButtonList / Giving Error?
Dec 6, 2010
When I refresh a page (either manually or with meta tags) after uploading an image with AsyncFileUpload, it clears out a RadioButtonList I'm using and this causes errors when the user tries to go to another page. The strangest thing is that the RadioButtonList only clears after the first refresh; when I click the RBL back to the original value, then refresh the page, it doesn't affect the RBL anymore.
All the applicable controls are enclosed in Update Panels.
(I wrote about a similar problem in forums.asp.net/t/1609492.aspx but I suspected that that problem had to do with a ModalPopupExtender and AsycnFileUpload combination. However, after removing the MPE, the problem still occurs so now I can only conclude that the AsynchFileUpload is the problem.)

I'm using a ListView and in both the ItemTemplate and EditItemTemplate I have, amongst other controls, an AsyncFileUpload inside a ModalPopupExtender and a RadioButtonList further down the page. The file upload process works great, but after uploading an image file and inserting it in the page, if you happen to refresh the page at that point, both the buttons of the RadioButtonList clear and one of my validation check for the RBL kicks in and an error message is, of course, displayed.
I have an UpdatePanel around the RadioButtonList, which is confusing because I thought that the purpose of AJAX was to shield the affected control from a refresh that occurs on the rest of the page.
One thing I tried unsuccessfully was to fill the RBL control again. I tried it after many different events (PageLoad, PageLoadCompleted, Databound, etc.), but none of those worked.
Actually, the RBL and DDL controls have been a real pain to deal with in .Net 3.5. Are they any better in 4.0?

I decided to use the CalendarExtender on a project and I converted it from VS 2005 to Web Developer 2010 Express. I initially added the AJAX toolkit for ASP.NET 4.0 and the calendar extender worked fine. However, I realised that the server didn't have ASP.NET 4.0 installed and I thought it would be simpler to add the toolkit for 3.5 instead and change the target framework to 3.5. I tried and then the CalendarExtender did't work at all. When you click the textbox nothing happens. There is the error on page - 'sys.extended.ui.textboxwrapper is null or not an object'
I tried switching the project back to 4.0 and using the other one and that no longer works for some reason. The same in 2008 Web Developer Express. I've clearly done something wrong along the way, but I can't work out what it is.
Here's the source for a page on a test Web Developer 2008 Express project.

I have used a radiobuttonlist to enable/disable the textbox in Grid View. I did this using javascript onclick event.
[Code]....
It is working fine when the page get refreshed too.
[Code]....
Then in a scenario, I have removed the radliobuttonlist items (items 2 and 3) dynamically. For the first time when its loaded its working without flaws. After a page is refreshing due to any serverside events, the javascript to enable/disable textbox is not working.
[Code]....
I have verified the HTML file, the radiobuttonlist is loaded without the onclick event.

foreach (Control control in ContentPlaceHolder1.Controls)
{
if(typeof(Control).Equals(Telerik.Web.UI.RadEditor))
{
label1.Visible = true; label1.Text = "dhchk";
// control.CssFiles.Add("~/styles/myStyle.css");
}
}
Error;-
'Telerik.Web.UI.RadEditor' is a 'type', which is not valid in the given context
Also, is this the correct way to add CSS class to radEditor controls ??
control.CssFiles.Add("~/styles/myStyle.css");
I actually wanna add 3-4 customized classes..how to do that?
also I was wondering if I can add some javascript or something in my Master page that will detect the ALL the radEditor controls and set their css classes ? don't know much of Javascript..how can that be made possible? how do I go about that? but first I want css classes to be set in code behind..what's wrong with the code?
[EDIT]
@Geek..I tried calling like this..is it correct?
Control c = new Control();
DoSomething(c);
now its giving this error in the method:-
The type or namespace name 'c' could not be found (are you missing a using directive or an assembly reference?)
[EDIT]
I do have this namespace added "using System.Web.UI.WebControls;" why this error ??

When connection losts during form or data sending/receiving process on my Asp.NET web sites. Standart "Page can not be displayed. Try again." page shows up. How can we do it like facebook?

Strange problem, not sure why it's happening. Basically I have inside an UpdatePanel a dropdownlist, a textbox, and a regex validator. page loads, ddl is bound and then based on the value in the ddl, a different regex is applied to the textbox. DDL could have search by "date" (with date regex), "last name" (with az regex), or "zip code" (with a zip regex). This way one search box can be used with 3 different regexes. Select zip code in the ddl, the OnSelectedIndexChanged is fired and the new regex is applied to the textbox. Simple.
The problem is, though, is that the page loads, I select Zip Code in the DDL, type in a zip code and then tab out NOT clicking the search button, and as soon as I do the regex validator fires with the red *. I wait about 2-3 seconds and it appears there's a postback that's fired somewhere because the textbox gets cleared out. Here's the update panel.
[Code]....
There is nothing in the code-behind that causes any postback except the dropdown list that applies the appropriate regex to the textbox.I see no reason why after 2-3 seconds the textbox gets emptied out. Is there a way to stop this?

I thought my issue was related to the Validators not working in UpdatePanels but that does not seem to be the case.
All validators fire when they should but, the error warning message clears when the updatepanel updates.
for example...
textbox1 range 1 to 23. dropdown1 updates the updatepanel. enter 99 error shows, but will disapear when I change value of dropdown1. textbox1 value still 99 so validator message should still show but it does not.

I have the same problem as [URL] However, the solution doesn't work for me since I'm using .Net 4.0 and xhtmlConformance is not there from start.
Basically, using a master page, the RadioButtonList still do the whole page postback even it's in the UpdatePanel. When I put the exact same code in a standalone page without a master page, it works as expected.

I have a very strange problem with my website... I created a rather large page, consisting of a few tables with some labels and textboxes where the user can enter a mechanical car setup (it's for a racing game).
I was working with simple textboxes previously, but I recently switched over to a NumericBox control which should allow only numeric input using some client-side javascript. The NumericBox control is simply a UserControl with a single TextBox on it, and some client side events are added to this textbox which call methods from a single javascript file ("Scripts/numericValidator.js")
When I put a couple of these boxes on a page it works just fine, I can only enter numbers. For it to work though I need to add the script to the page and I do that using this line, either in the head content or in the body content controls:
asp Code:
<script src="../../Scripts/numericValidator.js" type="text/javascript" />
(the path is chosen with the 'Pick URL' dialog so it should be alright, and it does indeed need to go up two directories first as the page is in the '~/Pages/RequireLogon" directory) However, after replacing most of the textboxes on my large page with NumericBoxes, and adding this script line to my aspx code, the design view is 'broken'. I cannot see any of my controls anymore, and I cannot even put any new controls on there. It seems like the Content control is missing, even though it's still there just fine without errors in the aspx code.
When I remove the script line, the problem is fixed again, the controls re-appear. So it's definitely the script line causing the problem, but I cannot see how it could...I tried it with a new blank page and the problem appears there too. If I use this simple page with just a button:

Alright, I am completely baffled by this one. When filling out this page in IE8, it will SOMETIMES clear all entered data (including radio choices) when you select Yes, No, or Not sure (line 892 in the code). This is a postback question, as it should potentially show more questions. This problem does not happen in any other browser, and rarely in IE8. I have no idea what is causing it, the code I am using has been used in similar applications and I can't find any change which results in this behavior.
The full code can be found here: http://pastebin.com/a12cPzyF

I have master page
MyMasterPage.aspx and content page MyDefault.aspx.
MyMasterPage.aspx has one input button [value="Menu-1"]. When user click the button, the button will pass value "Menu-1" into
TextBox1Default1 at content page MyDefault.aspx, and then refresh
UpdatePanelDefault1 at content page MyDefault.aspx asynchronously.
My problem is the post back is full post back when refreshing UpdatePanelDefault1. I would like asynchronously post back during refreshing UpdatePanelDefault1. copy the full code MyMasterPage.aspx and MyDefault.aspx below, and then paste / overwrite it into your blank aspx page for testing. I am using VS 2008
Below is full code MyMasterPage.aspx.[Code]....

I've built a page which has an update form, and above that, a photo (based on the same edit). The photo is loaded based on the selected table row being edited.
On this page, I've got a button that opens a modal in an iFrame and allows the user to update just their profile image (all works fine). But when the modal is closed, I'd like to reload JUST the photo (and not the entire page), as it will have changed.
How should I go about doing this? I assume I'll need to use some Ajax controls?
