I have a grid which houses a modal popup panel. When the grid binds it gives a flicker. The modal popup panel becomes visible for a second and then hides in the grid. Is there a way I can avoid this from happening.

I'm working on a webform with various controls. Depending on user-input I show/hide (using JQuery's show()/hide() functions) bits of the GUI. However if the form is posted-back and fails validation, I want the GUI to remain in the same state it was pre-postback rather than returning to the first-load state. Obviously the ASP.Net controls retain state, but I have HTML containers that are pure client-side objects.
In attempting to design a solution I find myself heading towards the murky (and tricky-to-debug) realms of hidden form fields - more reminiscent of my pre-JQuery work than anything 21st Century :-(
I want to create a searching work to fill the gridview detail acc to seach params.. When we enter text into search textbox it fills the grid, that works filne without postback. After this i have to fill the form values accroding to link clicked in Gridview. I uses the updatapanel in grid like
[Code]....
When the grid fills it doesnt fill my form... why it happens.. i used the Updatapanels multiple as well.. If i use the Updatepanel in whole.. it may flicker while filling in the form values.
our pages flicker when using modal popups.
Any way to reduce the flicker?
We tend to postback a response to the primary page to change data, or do something, then return a modal popup with results of change or action.
Upon showing the results or a confirmation screen in the modal popup, there is flicker.
I have block of code that consists of a textbox a button and a dropdown. The text entered in the text box filters the dropdownlist when the user clicks the button. The Ajax works great when it is in a simple page but if I put the same code in a User control I get flicker.
View 2 RepliesI have a page with two updatepanels both using a timer's tick event to do various bits. The script manager is set to conditional updates and the panels are set up to use specified triggers but when the tick event fires for either the page flickers and the scrollbars reset to midway down the page. This renders my application unusuable.
View 4 RepliesFrom one of my webpage, I am opening up another form as ModalDialog, and on this form, I have a Grid, Treeview and some other controls.
[Code]....
I have some code on click of Treeview Node, I fill out other data in Grid on click of Treeview Node.
Now the problem is when page posts back ( on click of Treeview Node ) , page flickers once during filling up data in Grid.
Basically whenever page.ispostback is true, page flickers, Now I want to avoid this.
I have to keep "SmartNavigation="false"" on this page because of some of the Treeview Problems.
Specifically on Node click of Treeview and on Update button press.

I can't figure out why I might be getting this error. It happens on an ajax call.This is the full error text:

I created a MultiHandleSliderExtender on a web form. All works well with updating the two textboxes with the value. The problem is that when I switch to designer mode, I get the following error:
The code is as follows:
[Code]....
[Code]....
[Code]....
The control works and the 2 text boxes get updated, but I tried putting in an update panel with a trigger on mh_1_BoundControl but it never fired. I removed it thinking that was the cause of the error, but no luck.
Now when I add another sliderextender below it for a different value, the code throws an error:
Microsoft JScript runtime error: Sys.InvalidOperationException: Type AjaxControlToolkit.SliderOrientation has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded. A possible cause is a change of settings during a partial update.
I found this example on this site and tried implementing it but to no avail.
Ajax calls within <table> tag causing error.
htmlfile: Unknown runtime error
I am pasting here full code to produce error. Please help me to sort it out.This is my code for .aspx file. Paste it in new .aspx file inside form tag.

I have a page that has a few NumericUpDownExtenders, and the same page has some validation like RequiredFieldValidators. The problem is that when you click either of the arrows for any of the NumericUpDownExtenders, it's causing the page to try to validate. This ia making all the "required" boxes for every required field on the page pop up as if you just tried to submit an empty form.If you don't touch the NumericUpDownExtenders, then the page works exactly as intended. The "required" boxes only pop up if you've gone into one of the required fields, typed something, deleted it, and put the focus in another field.How do I fix the NumericUpDownExtenders to make them stop causing the validation?
View 2 RepliesI have a dashboard made of multiple webparts. One of the webpart is a usercontrol with a timer wrapped in UpdatePanel. When it is loaded in the dashboard I notice that it causes a Page_Load, and that triggers personalization procedures aspnet_PersonalizationAllUsers_GetPageSettings and aspnet_PersonalizationPerUser_GetPageSettings to fire.
Can can I avoid that? I read many posts on Timer controls within UpdatePanels, and it is my understanding that Timer would cause a full page postback, but only render the UpdatePanel that it is part of. However, these personalization functions execute every time Timer ticks.
am trying to fix an issue. I have an ASP.NET Ajax's TabContainer on the page. And each tab there is a gridview control that gets binded onload. However for some reason the browser gets closed automatically after the page renders. If I remove the TabContainer then it works fine. I think the binding code will no way effect the browser to close bacause no where in my code I am registering any Script block.Also one notable thing is this happens only in IE 8. It works fine in firefox and other browsers.I don't know if anyone encountered a similar issue before.

When I remote the MaskedEditExtender and MaskedEditValidator, it doesnt show that (undesired) behaviour anymore.Is there something special these controls do that cause them to refresh? Is there a workaround for this?
I think ive narrowed down my problem, I have a form but the "submit" buttons are being handled by Javascript - since i need to build arrays manually outside of the model for processing
[Code]....
I'm calling the Controller Action "Update" and passing it to string Arrays, when its finished - i want it to redirect to another action - it doesnt.
[Code]....
I just really wanna construct those arrays, and pass them to a controller...i think the ajax is waiting on a result and ignoring the redirect.
Below is the sample code on using the update panel. The page just has a button and a label. On button click it updates the label with the server time. Though the label is inside the update panel the page goes for a complete postback. in understanding why it is behaving like that. I tried the options of Updatemode, using different script references nothing seems working for this simple application.

I am using VS 2010 and making extensive use of tab panels with gridviews inside of each. I very often am required to reformat the whole document as it seems that the gridview mark-up gets completely reformatted in one continuous line. In the act of reformatting unwanted things get inserted such as linebreaks. When I was using VS 2008 this behavior was even worse. Does anyone have a suggestion to fixing this issue? I am wasting time because things are changing visually and tested work is getting automatically changed.
View 4 RepliesI have a gridview which has a checkbox column which are set to automatically postback. When a checkbox is clicked, a partial postback occurs, and the associated record is displayed to the user (this is the required function).My problem is regarding when a user clicks a number of checkboxes in quick succession. I have got ajax request queuing working fine, so each checkbox postback is eventually dealt with. However as the gridview also postsback, it resets its viewstate on which boxes are checked, removing some of the boxes which the user may have checked.I've attempted to take off the viewstate on the gridview which seems to achieve nothing, neither does placing the gridview in a separate update panel.
View 1 RepliesIf a user enters "<" or if it already exists in a textbox inside an update panel, I am getting "internal server error 500" during post back. I believe the page suspects a HTML injection and is attempting to stop it. I could use Page.EnableEventValidation to avoid it but I really don't want to do that. Is there any other way, I could resolve it (like replace < with > or something like that)?
Update:
This is happening in a textbox inside a gridView.

I have a modalpopupextender and I want to be able to update the information without causing a postback and having to re-show the modal, normally I use an updatepanel and this is working in most cases but I have an issue with a repeater where the ItemCommand has been set but clicking the button does not fire anything, unless I set the repeater as a trigger but this then does postback and I lose where I am. Not the usability I want to provide.
View 4 RepliesI have a link button inside a template field of a gridview. The gridview is wrapped in an update panel. I want the link button to fire an async postback but it always fires a full postback. Why is this?
This is a similar problem to the one described in the link below. However, I have tried doing a RegisterAsyncPostbackControl in the gridview databound, but this did not work.

I have a small website that consists of 1 masterpage and 4 aspx pages. I'm using AJAX controls in this project. I'm trying to attain a no-flicker site, however, whenever I go to one of my aspx pages, the screen flickers. I have the <ScriptManager> in my masterpage along with the <UpdatePanel> and <ContentTemplate> tags. In my aspx pages, I have only the <UpdatePanel> and <ContentTemplate> tags.My masterpage consists of a Logo, Login, and ASP Menu Control. Is there something simple that I might be missing?
View 11 RepliesSince last week I've had a really odd issue with PageMethods and the back button which i've never seen before. Essentially, I have a 'home page' which on document.ready (using Query), loads some data through PageMethods, and then renders a list - from which you can click through to a details page about the item. In general use, it works fine. However, using the back button after clicking through (ie: going back to the home page), it throws a PageMethods error. The browser's 'authentication required' prompt appears, and if you click cancel, the server returns a 404. The error returned by PageMethods on the client side is 'authentication failed'.
Just FYI, the application is using ASP.NET forms authentication. The weird thing is, this happens as soon as you click the link and click back. It's not like the authentication cookie has expired or anything, and if you click cancel when the prompt appears and refresh the page, it works fine. I just can't work out what is going on. I've tried disabling caching on the page [as I thought it was something to down with some browsers' caches of the DOM), but the same thing happens. One workaround i've had is to redirect the page to itself if the PageMethods error is 'authentication failed', which does work - but only when you cancel the authentication prompt. Obviously the prompt appears, which is not ideal. I don't understand it, and the user is clearly authenticated. Does anyone have any idea which might be happening? It's happening in Chrome, Firefox, and IE.
I am having issue with my ModalPopUpExtender's OKControlID. I have a button inside an update panel that should do AsyncPostBack. The button works fine and runs server side code but it causes full page postback. How do I solve this issue? I want the 'OK' button inside the modalpopup to call the serverside code and update Label control 'label3' without causing the page flash. Given below is my code;
