Inside gridview there is a dropdownlist and a button on each row. On button click I am opening a panel through Modal popup extneder.
Inside that pop up there is again a dropdownlist. I am adding an item into this dropdownlist based on the selection from the dropdown inside gridview.

But first time this inserted item is not getting reflected in the dropdownlist. But after one postback this item is getting reflected.
AJAX :: Editing Image Inside DetailsView Inside UpdatePanel?
Oct 4, 2010I'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.
The source code:
<asp:DetailsView ID="dvMovie" runat="server" Height="50px" Width="695px"
AutoGenerateRows="False" DataSourceID="sdsMovieById"
BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" [code].....

View 4 RepliesAjax Nested Datalist In Updatepanel
Oct 27, 2010I need to input nested data (data entry) and i am using datalists for the same. The details include many details and I am managing the same using controls for each in information.The parent datalist can have max 20 rows with 7 rows in each child datalist. I tried to bind the datalists with max rows, due to which the rendered page size was almost 12MB and it took more than 2 mins to load.Alternative to this, I put the parent datalist in updatepanel and bound it to one row initially. Onclick of add button, i implemented an asynchronous postback to add new row to the parent datalist datasource and update the updatepanel to display the datalist. The new row is displayed properly in datalist, however it gets reset to original datalist after some seconds.

AJAX :: ModalPopupExtender Inside UpdatePanel?
Apr 15, 2010I 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.
Here is the code:

AJAX :: Dropdowns Inside Updatepanel?
Dec 13, 2010I'm having a problem with a dropdown throwing an error:
Uncaught Sys.WebForms.PageRequestManagerServerErrorException:
Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.Only Sometimes.
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).
AJAX :: PlaceHolder Inside UpdatePanel?
Nov 8, 2010TThis time I'm facing some unusual behavior with a web page that I'm developing. I have a table with several controls and gridviews and stuff. At some point of the table, i have to show some rows (they were hidden) when the users clicks a button. I was doing this with a PlaceHolder, but now i have to do it without the postback being displayed. I thought: "That should be easy, all i have to do is to put the PlaceHolder inside an UpdatePanel, and that's it" but no, no no nooo!! NOTHING IS THAT EASY!!! It actually works but it puts the hidden rows at the top of the page, not where they suppose to go!!My code is the following:

View 1 RepliesAJAX :: PopupControlExtender Inside The UpdatePanel?
Jun 16, 2010I have a PopupControlExtender inside of the UpdatePanel. I use it to edit some of the values on the website.
Basicly it looks like this. If you have PopupControlExtender inside of th update panel whenever a user triggers a partial postback javascript creates the popup panels outside of the UpdatePanelControl - to make sure they are always on the top of other elements. So after every postback you get more and more elements with the same clinetIDs.
Here is a code from Firebug - you can notice Panel1 and all the controls inside of it being generated 3 times when i load a page (once) and twice after two partial postbacks:

Oh and i use it actually inside the listview that itself is embeded in the update panel so i cant really use it outside of the update panel.
