View 4 RepliesI'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 1 RepliesI have a gridview inside UpdatePanel.
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.

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.
Here is the code:

I'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).
TThis 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:
<asp:UpdatePanel runat="server" ID="uplAutoridadesAmbientales">
I have an animationExtender, I have an update panel iniside of it with the updatemode Conditional and I have the button that triggers it, but whenever I click that button, the whole page reloads and the animationExtender closes. Why would it do that?
View 1 RepliesI 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.
I have a page with two ajax toolkit popupcontrol extenders, both have a Linkbutton inside the popup window, which is inside a panel and updatepanel. The difference is the second one (Linkbutton2) is inside a Gridview, which is also inside a Updatepanel.
The first one works fine, but the second one does not fire when click on it. The code is as follows:

I have a custom control created to autofill the box as typed in. Its working great. But if I put the control inside an Update Panel, it works for the full postback but if partial postback happens (because of the update panel), it does not work.
View 7 RepliesI started a new project using VS2010. I have a menu control connected with an XML datasource inside UpdatePanel, Menu control works fine, problem is the styling. using a StaticHoverStyle Css works only after the page reloads, when I click a menu entry, the entry is selected but StaticHoverStyle does not reflects the menu items anymore (of course when I hover the items) Same behave with both Net versions 3.5 and 4. When I remove the UpdatePanel the StaticHoverStyle comes back to life ( post back occurs ).
View 1 RepliesI should probably say I love these forums, I've been viewing for some time and have found loads of valuable information. I'm having a problem with my project, I have an updatepanel containing several items (Two Daypilot Schedulers and a Literal Control). I have set it to conditional and have it update whenever bookings are added/modified in the schedulers. This all works perfectly! I then have a literal control which contains div items with onmouseover= parameters. The control basically contains a list of pending booking requests. On Page_Load I call a method which populates the list...which works fine.
However, whenever I call the UpdatePanel.Update() method (say, when a booking is added), the schedulers update but the literal control does not. I have gone through the debugger and found that the LiteralControl.Text property is correctly set to the new updated list just before calling the Update() method. So basically it all works perfectly apart from the literal control not updating along with the schedulers in the UpdatePanel.
I have a couple of dropdowns inside an Ajax Update Panel. When I try to rebind the controls or set the selected index of the drodowns inside the panel, they don't respond.
For example, I update the database records and need the dropdowns to display updated data. I set the data source for the dropdowns, rebind them and update the UpdatePanel, but it still shows the old data.
