I have recently updated ajax control toolkit from 30512 to 30930 (same applies to latest version of ASP.Net Ajax Library) and came across a reproducable problem.For a long time I used to have a control with ModalPopupExtender & RoundedCornersExtender which was placed inside of an UpdatePanel and everything worked great up until recently.
Now I'm getting "Microsoft JScript runtime error:Sys.InvalidOperationException:
Two components with the same id 'rce' can't be added to the application." during an async postback.Click on button "Wait" and error comes up every time.
I have a menu of buttons inside an UpdatePanel (UPD_Menu) so that buttons can be enabled/disabled without refreshing the entire page. When a user signs in, the Sign Up button is disabled and the Profile button is enabled. Likewise, when the user signs out, the Sign Up button is enabled and the Profile button is disabled.
Inside this UpdatePanel (UPD_Menu), along with the buttons, is a ModalPopupExtender that is fired by the Sign Up button (TargetControlId="BTN_MenuSignUp") that pops up a dialog Panel (PNL_SignupProfile) that contains yet another UpdatePanel (UPD_SignupProfile) that contains a Submit button as well as a Cancel button (CancelControlId="BTN_SelectCancel").
The behavior I am getting is when the user clicks no other button than the Sign Up button, the dialog (PNL_SignupProfile) pops up and is modal. The Submit button closes the dialog and makes the once-hidden panel appear under the menu of buttons. This is not good as only the inner UpdatePanel (UPD_SignupProfile) should be updated without affecting the outer UpdatePanel (UPD_Menu). The Cancel button works as it should by simply closing/hiding the dialog.
If a user clicks any other button in the menu first, nothing happens ( no codebehind yet) but when the dialog (PNL_SignupProfile) is shown, the Cancel button causes the hidden Panel (PNL_SignupProfile) to appear under the buttons. I've tried many different things to no avail...including putting the dialog panel in different places and even controlling the ModalPopupExtender from code.
The only code I have so far is for handling the signin/signout and enabling/disabling the signup and profile buttons based on user signin. There is no code yet to handle the menu of buttons nor the submit button of the popup dialog.
I have a modal popup extender with one control (ascx) this control has a label that on onclic method call other popup extender.
It's has other ascx, it's has a button for a search. When I do Click in this button in first time, the event click not fired and there are a javascript error that say "this._activeDRagVisual is null reference".
In the other hand, If a use de second popup inside an asp page the event and control work correctly. The problem is with the popup inside popup.
I try I cannot seem to find a satisfactory solution. As far as I can tell from the documentation a ModalPopupExtender should be able to reside inside an UpdatePanel. However, I simply cannot get it to work.After the first refresh of the UpdatePanel I get errors of various kinds depending on what I've tried.
What I'm trying to accomplish is having a button inside an UpdatePanel which launches a popup. Another button inside the UpdatePanel causes a partial postback. And finally a button within the popup has to cause a partial postback. I have tried at least five different approaches to this problem and finally I gave up and went with a very inelegant solution. I don't think my requirements are all that strange, am I doing something wrong?
First I tried this:
[code]....
This works fine until after the first postback when the Cancel-button (Button4) starts causing synchronous postbacks and the textbox starts to fill up with commas. I also tried the same as above but placing an UpdatePanel within Panel4 (the popup) - no go. Then I tried causing the postbacks in javascript launched from the ModalPopupExtender's OnOkScript - still it starts failing. I tried another couple of attempts all of which failed. Finally I decided to move the ModalPopupExtender outside the UpdatePanel, add dummy buttons and a bit of javascript to launch and hide the popup. Although this satisfies my UI requirements it just plain wrong from a design perspective and it annoys me that I could not get the extender to work inside an UpdatePanel. Has anyone succeded with placing a ModalPopupExtender in an UpdatePanel with the requirements I stated above? Or should it be added to the list of controls that's just not compatible with the UpdatePanel?
When I have a control within an UpdatePanel which is within a ModalPopupExtender panel, after the FIRST successful display of the modal (by clicking OK), the events of the control are not functioning. I have the full source code below of a working example of this. How do I get around this?In the sample, when the modal is first opened checking and unchecking the checkbox updates the textbox. Clicking OK updates the textbox in the outer UpdatePanel. Opening up the modal a second time will now prevent the checkbox from updating the textbox.
I have a Gridview which is inside a Updatepanel which is updated through a Timer Control every 5 seconds. So every 5 seconds I get new data in the rows. I am facing an issue in which I want to display the whole mult-line content of my Textbox(es).It displays fine but the modal window disappears after the UpdatePanel is updated.
How do I display this pop-up modal window and make it stay while the UpdatePanel continues to update the rows in the background?
I know I'm missing some simple little thing here...
[code]....
(I put in an Exit Sub at the very top so I'm sure it's not the code).
Essentially, everything is working just great except I need the modal popup to close only if the form data is correct and I choose to close it. The UpdatePanel, "UpdateInfo", is in place to allow form processing without interfering with the UpdatePanel, "UpdatePopup". In my real code, I have a hidden label that I use to report errors. The UpdateInfo is vital for showing/hiding the error but the popup must remain showing...and modal. (I had something like it working once before but I've re-written it since and just can't remember how to do it.)
I have an gridview which contain a link button. When I click the linkbutton I need to populate a Panel which is out of the gridview. Its showing an error.Here my code is,
I'm trying to add and edit an image which is located in a detailsview which is inside an UpdatePanel. After I read relevant topics in the forum I installed the Ajax Control Toolkit. Below is my source code. When I used it only for insert new image it worked great. The problem caused when I tried to implement it on the Edit mode, i.e. when I tried to edit the image and upload a different image. Unfortunately it didn't work as I hoped. Nothing happend and the image hasn't been changed. I also tried to change the IDs (AsyncFileUpload ID) to be the same in both places but it didn't work either.
I have a form in which I have a gridview with a LinkButton culumn in which when the user clciks a modal popup extender shows up. In the modalpopup I have a dropdownlist which is filled from DB in code behind. but when the user clicks on Add button in modalpopup panel, the selected value of the dropdownliast is always its default value.
[Code]....
here is my code behind:
[Code]....
I traced my code behind, the fillData() which fills up dropDownList is called only once in page load's first time.
PS. I understood the problem exists only when the modal is poped up by linkbutton click of gridview. when It is poped up by a button outside the grid it workes fine.
I'm trying to use the AJAX "RoundedCornersExtender" control on a <div>. I've assigned an "id" to the div....so, my code looks like this:
HTML Code: <div id="headerLogo"> For the TargetControlID of the RoundedCornersExtender, I've given it "headerLogo". However, when I run the app, I get the following error:
Code: "The TargetControlID of 'RoundedCornersExtender1' is not valid. A control with ID 'logoHeader' could not be found." My guess is that the "id" for the div is designated as a CSS identification. If this is the case, then how do I assign the <div> to the AJAX control?
I have a gridview inside a ModalPopUpExtender, the grid view have the button add delete and edit when i clic one of the button of the gridview the popup is closed. I wont to close the popup when the close button is clicked.This is the asp.net part:
I have a panel that uses the RoundedConersExtender to round the corners on the border around the panel. It was working fine in IE7 but now in IE8 the top and bottom seem to be separated. I looked through previous questions and it seems that this was a problem with Firefox as well but no solution. Does anyone know a workaround other than using compatibility mode?
I´m testing roundedcornersextender and it don´t work.I tryied round some controls (panel, div and textbox) without success.Am I doing something wrong? See the aspx code:
Which I found useful to create gridview with dropdown filter. What my gridview differs from your one is based on ID, a modal is loaded. E.g. there is a column called "review" and in that column there is image that when clicked it loads a modal with details. My question is, how do i do this using the code provided by you. So ID is passed back to code. (So backend knows which row is clicked).
I am using a third party control that upload images. It works fine when i place it on aspx page (Outside DetailView) but I want to place that functionality inside EditItemTemplate but it just never work .
I am using FileUpload control inside UpdatePanel, but cant get it working and keep getting error : "Object reference not set to an instance..." on line: If fuAvatar.PostedFile.FileName <> "" Then I have checked several forum and people mentioned that we need PostBackTrigger but i just cant get it working and keep getting the "Object reference not set..." error. My FileUpload control is inside a panel and along with another control, and the upload occurs when user click on Finish button.

I am using an updatepanel, with a bunch of dropdowns that have an onchange for Javascript, that use ajax (partial page postback). The problem is: I have two dropdowns at the top (also inside the updatepanel) that let me change the current month or year. Sometimes...they change the page (response.redirect), and sometimes they throw that error above. Also, they are the Only two buttons on the page that aren't doing an "onchange" and then ajax stuff....they are actually posting back the entire page to the server (or trying to).
