C# - PopupControlExtender Inside UpdatePanel?
Jun 15, 2010
So i use PopupControlExtender (to edit some of the fields) inside ListViewControl which itself is embeded inside an UpdatePanel.
The problem is as follows whenever you cause partail postback the popup panels are created client side outside the updatepanel. And you get more clientside controls with the same clientside ID. When you postback with popup panel the server side control eg. Texbox has Text = clientsidecontrol1.text, clientsidecontrol2.text, clientsidecontrol.text3
Is there a way to prevent this.

I 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 know this may be easy, but I have looked at it for a bit of time and maybe my brain is going in circle.OK, I am learing PopupControlExtender. Looks like it is a good thing to have. One (style of) example is to have a TextBox. Click on it and the PopupControlExtender will come up. Sample code may be like the Example 1 in this
Introduction.
Question:
Why there is a need to put UpdatePanel inside the Panel? It is the TextBox which needs to be updated. Why the TextBox is not put into an UpdatePanel? (I try Example 1 and it works without having to put the TextBox inside an UpdatePanel.)

I have popucontrolextender inside gridview and by using dynamicservicemethod I could pop out panel. I followed following article to accomplish this.
[URL]
However, one of my popup takes a while to come up and I am sure users doesn't want to wait that long for panel to pop up. I want something like progress bar image to come up after user hit the row in the gridview. I can do this in modalpopupextender but I can't find any example to accomplish this using PopupcontrolExtender inside gridview using dynamic service method.

I have two update panels and one javascript control.
When the javascript button is clicked, it forces a partial postback on UpdatePanel2. UpdatePanel2 is populated with dynamically created buttons that have javascript effects (jquery) but when click can also induce a postback. My problem is that, when clicking on these dynamic buttons, the whole page does not do a partial post back but rather UpdatePanel2 itself does a partial postback and everything is gone.
However, what I want to do is be able to tie each of the dynamic buttons in UpdatePanel2 (After being dynamically created) and make them an asychnonous triggers to UpdatePanel1. So that when clicking on these dynamic buttons, ONLY UpdatePanel1 is doing a partial postback refresh. UpdatePanel2 stays put and remains the same.

I have a script inside an updatepanel. This script needs to be inside the updatepanel as it must be located in that spot.
Now when we click the "LinkButton" to update the updatepanel, the script will dissapear.
It seems that the script only is initiazed on the first Page_Load and Refresh of the page.
How can we keep it when pressing the "LinkButton"?
Complete code is below:

I 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.
like ddl.items.insert(0,'xyz');
But first time this inserted item is not getting reflected in the dropdownlist. But after one postback this item is getting reflected.

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.
The source code:
<asp:DetailsView ID="dvMovie" runat="server" Height="50px" Width="695px"
AutoGenerateRows="False" DataSourceID="sdsMovieById"
BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" [code].....

I've got a textbox being used to enter a password inside a wizard control. I'm trying to get a password strength meter working with it.
Unfortunately, the password box isn't visible until step 4 and this means that I can't register the event handler onload() and putting some JS next to the PW box to register the event handler doesn't seem to fire. I'm guessing this is due to the contents of the wizard being loaded through an AJAX postback.

I have two DropDownLists inside an UpdatePanel.
The values shown inside the second are dependent of the selectedValue on the first, so, I need AutoPostBack=true.
But, whenever the selected value in the first DropDownList is changed causes the UpdatePanel reload.
How can this be solved?
PS.: The UpdatePanel's UpdateMode property is set to Conditional.

I have a ScriptControl (requires ScriptManager) with JavaScript to handle client-side interactions and ICallbackEventHandler to communicate back and forth. Everything works perfectly with one or multiple instances of the control on a page. I placed the control inside a GridView with sorting and it still works. However, I place the GridView in an UpdatePanel and now whenever I sort I get the following error for each instance:
Sys.InvalidOperationException: Two components with the same id 'GridView_ctl02_MyControl' can't be added to the application.
Can someone point me in the right direction on how to solve this? I am assuming ScriptManager is not disposing of the old Sys.UI.Control objects before trying to $create() the new ones with the same ID. I thought the UpdatePanel/ScriptManager combination would automatically take care of disposing objects that would be replaced?

A little pseudo code to provide some background:I have an ASPX with a placeholder and a buttonWhen the button is clicked it adds a web user control (uc1) to my placeholderhe uc has a buttonWhen clicked it adds a different user controls (uc2) to the placeholderStepping through the code, if I look at the placeholder.controls.count before and after the button-click in #4 the count increases by one, as you would expect.The problem is that the uc2 added in #4 doesn't appear on the screen. So, I wrapped my placeholder in an UpdatePanel. I've never used one before. So, I could refresh the placeholder after the uc2 was added.relevant ASPX code

In my UserControl, Im trying to update a updatepanel that is inside a repeater like this:
HTML-Markup
<asp:UpdatePanel ID="updDocumentQuickView" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Repeater ID="repFolders" runat="server"
[code]...
The end result I get is that updDocumentQuickView is the UpdatePanel that gets updated, and not updFiles. If i wrap an UpdatePanel around lnkFolder, then that UpdatePanel gets updated, with the same C# code. Ive checked what kind of data that are sent back with fiddler, and the wrong UpdatePanel is sent. Im getting the correct RepeaterItem, and both repFiles and updFiles are found. What do I miss to get the right UpdatePanel to get updated?
UPDATE
Hawxby solution solved the problem with updDocumentQuickView getting updated, thanks for that. But im still having problems with updFiles sending nothing back. Some further testing, with putting literals inside updFiles and working, tells me that theres something with repFiles that isnt returned. repFiles does have data that is bounded.
FINAL SOLUTION
repFiles.Visible were set to false in repFolders_OnItemDataBound, no wonder it didnt show.

I am having a custom ASPX page with following structure. Its having 2 update panel and I have a ImageButton outside them. The two UpdatPanel are triggered by this ImageButton.The Problem is whenever user clicks the Imagebutton, the image in the ImageButton is getting reloaded...it disappears and the reappears. I am not able to figure out why the postback is happening when the imagebutton is place outside UpdatePanel. Is it because I am using this Imagebutton for triggering AsyncPostBack in UpdatePanel?

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 using fancybox to display the contents of a div when clicking a link. This works using the code below:
<a id="popupTrigger" href="#popup">popup trigger</a>
<div style="display:none">
<div id="popup">
<asp:UpdatePanel ID="HerkomstCodeUpdatePanel" runat="server" UpdateMode="Conditional">
<ContentTemplate>
This content displays inside fancybox.
<asp:TextBox ID="CurrentTimeTextBox" runat="server"></asp:TextBox>
<asp:Button ID="RefreshContentButton" runat="server"></asp:Button>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</div>
And the JScript:
$(document).ready(function () {
$("#popupTrigger").fancybox({
autoDimensions: false,
height: 250,
transitionIn: 'elastic',
transitionOut: 'elastic',
width: 400
});
});
Now what I'm expecting it would do is that when you click the button (which is displayed inside fancybox) it would update the textbox and do whatever I define it to do in the codebehind. Unfortunately nothing happens when I click the button.
I've tried to trigger a __doPostback myself passing the ClientID of the updatepanel and/or the button itself. I can't seem to trigger the event in the codebehind however.
The thing is if I remove the fancybox, the updatepanel works as expected. So I am guessing if I can somehow find out what eventhandler logic is behind the button before I create the fancybox, I might be able to recreate the eventhandler logic after attaching fancybox? I just can't find it anywhere...
I am using ASP.Net WebForms 3.5 and JQuery 1.4.1
Update
I got it to trigger the codebehind button_click event by overriding the clientside click event on the button using the code below. The key is in using the name of the button as the sender object for the __doPostBack event. The only problem that remains is that all other values aren't posted back anymore. If I type anything in the textbox, click the button, my codebehind doesn't know what's in the textbox anymore.
$("#popupTrigger").fancybox({
//.... other options,
onComplete: function () {
$("#RefreshContentButton").click(function () {
__doPostBack($(this).attr('name'), '');
});
}
});
