AJAX :: ModalPopup / UpdatePanel From Codebehind, Inconsistent Behavior OnClick?
Aug 4, 2010
I have a simple form with a list of linkbuttons, each fires the same onclick event which sets an indicator image. I have a dummy button with style="display:none" which I have set as the TargetControlID of the modal.
onClick event from the imagebutton, the modal is shown via modal.Show(). The cancel button inside the modalpopup fires an event which turns off the indicator image and hides the modal via modal.Hide().
The events fire perfectly, it's very simple! Although after doing some testing I noticed the modalpopup is not presented after the 6-10th cycle of clicking the open event, then clicking cancel. The grey background appears but it is behind the main panel and the modal is either presented behind this or is just simply not displaying.
I spent hours researching various methods, implemented the CancelControlID to see if it was somehow tied to my call of modal.Hide() that fails.This occurs with an updatepanel only. The behaviour is much cleaner this way, so I would hope to be able to implement this. I have basically eliminated everything but these two events!

As I understand it, the ModalPopup is displayed when it's attached to another control. So when I click on the target control I will see the ModalPopup.Is it possible to display it without having to attach it to another control? Basically, the button click event will execute a few lines of code, and then it will display the ModalPopup.I ask because a button click event needs to do several processes before it asks the user for additional information. That's when the ModalPopup will pop up, and the user will enter the information there.

I basically have a web app where the user enters some form info in Page1. This info is submitted and a SQL database is updated. The user is directed to Page2.
Page 2 contains a summary of info submitted in Page1, a PRINT button, and two UpdatePanels. Each UpdatePanel contains a ListView where the user can add, edit and remove items. Once the user is happy with the page, they click PRINT. This takes them to a printer-friendly page with NO on-page navigation.
Once printed using the browser print button, the user clicks the browser back button. In this case it is always IE8 running the pages. When you return to Page2, the content of the ListViews in the UpdatePanels looks like the first step when Page2 was entered from Page1. All work done on Page2 from that intial point is not there. Click the browser refresh button and the entire page will load.
Why does this happen? When the user clicks the browser back button in the printer friendly page, I need the screen to show Page2 with all the info from just before the PRINT button was pressed.
I can provide code, but initially thought it would confuse/clutter the post.

I have a modalpopup extender attached to a button. That is to say the button is the targetcontrol id of the modalpopupsxtender. I would still like the onclick event of that button to work because only the onclient click event is working. How can i go about this.

A multiview with one View using a recaptcha and Modalpopup for response to a submit button within the ViewAn UpdatepanelI've spent hours and hours and hours searching around for any sort of solution that covers all of those without *some* sort of problem. If I put the menu inside, something won't work. If I put it outside, something else won't work. If I set 'conditional' or 'child-this-or-that' or whatever, *something* comes out to bite me. The recaptcha will vanish, or there are postbacks, or Modalpopup has gone agai

I am using a modal popup control which contains an UpdatePanel. There are one combo and few text boxes and Calendar control in it. When I select any item in combobox, then it's selection change event is fired and there iI set the values of other controls and finally I call update method of update panel. Functionality wise it works properly but it takes a time to update the panel.Here combobox contains around five thousands of items. But when it contains 100s of items it works good.

I have a databound listbox that is inside an update panel. When selecting an item in the listbox, I want it to populate labels in a panel that are displayed in a modalpopup. When I click on the listbox, I can see that the data is passed to the labels and the modal.Show() is executed by stepping through the code. However, the modalpopup comes up but with no data.

In my web application, i have declared modalpopup extender and corresponding div(popup control) inside master page to make it generic. In my page i am using updatepanel with a button inside it. Clicking on this button will fire the modalpopup extender. Before calling show() of modalpopup i am setting some text to a label inside the popup control. But when the popup comes, the updated text is not showing.

try to figure out what is wrong with my code but I'm lost. I've a ModalPopupExtender, triggered in code behind by the onClick event link button. The FIRST time I display my popup, it works well and if I close my popup using javascript, it works and I can get my popup back by clicking on my linkbutton again. But, if I click the "Save" button of my popup (which save data and close the popup), I can't get my popup to display again. Even if I close my popup first using javascript and then calling my server side code to save my data, the result is the same, I can't display my popup again. Seems like the postback "break" it.This popup is in an conditinal UpdatePanel and event trying to manually update the panel after the popup.show() method change nothing.Finally, I checked what server sent back to the browser using firebug and I can confirm that I received only view state information (no UpdatePanel to update), even after calling panel.Update().

I've inherited an ASP.NET project that has poorly designed HTML; in one section, the tags are wrapped with an tag to allow for "click the row to view the information" functionality. The code is:
<asp:LinkButton ID="ViewArticle" runat="server" CommandName="Navigate" CommandArgument='<%# DataBinder.Eval(Container.DataItem, "id") %>' >
<tr runat="server" class="list_item">
<td>some data</td>
<td>some data</td>
<td>some data</td>.........
How do I go about tying a JavaScript "onclick" event to the codebehind?

I'm constructing a LinkButton from my codebehind, and I need to assign the onclick to a method, and pass a parameter with it too. I have this so far:
LinkButton lnkdel = new LinkButton();
lnkdel.Text = "Delete";
protected void delline(string id)

I had an MVC 1.0 web application that was in VS 2008; I just upgraded the project to VS 2010 which automatically upgraded MVC to 2.0. I have a bunch of viewpages have codebehind files that were manually added. The project worked fine before the upgrade, but now the onclick even't don't get triggered. I.e. I have an asp:button with an onclick event that points to a method in the codebehind. When you click the button, the onclick event doesn't get triggered. In fact, when you look at the Page variable, IsPostBack is false.
This is really bizarre and I'm wondering if anyone know what happened and how to fix it. I'm thinking it has something to do with the changes in MVC 2.0; but I'm not sure. (deleting the codebehinds and moving that to the controller is not really an option since there is so many pages, moving back to vs 2008 is a last resort as I want to make use of some of the VS 2010 features like performance testing.)

Ran into a bit of problem when using PageMethods when calling a webmethod in the code-behind. My markup page has a radgrid which gets populated via the objectdatasource.Pagemethods works and returns data as expected when the objectdatasource binds the radgrid with some data but not when the objectdatasource returns nothing, i.e. radgrid is empty. PageMethods call has got nothing to do with the objectdatasource, I'm simply using its output to build a list of checkboxes dynamically on the client side using Javascript. And this is how my code snippets looks like:Markup page:
<script type="text/javascript">
function CallGetARInvoices(src,dest)

I've got a UserControl that's used inside of an UpdatePanel. The UserControl is a fairly simple form that appears via a ModalPopupExtender (which is also part of the UserControl). There are four DropDownLists, as well as some other UI elements. Three of the four DropDownLists have AutoPostBack="true", with SelectedIndexChanged events that fire on the server and cause some of the other DropDownLists to rebind. Two of the three DDL's that AutoPostBack are working fine. One of them, which I only just added, is showing some strange behavior. Let's say I bind five Items to it: 1, 2, 3, 4, 5. I set the SelectedIndex to 0, which makes 1 the selected item. If I select 5 and then 1 and keep toggling back and forth, everything works fine. The postback occurs and SelectedIndexChanged fires. Every time. If I ever select 2 or 4, the postback occurs but SelectedIndexChanged does not fire. Every time.
If I ever select 3, something bizarre happens and sometimes the value of the DDL reverts to 1. Even though breakpoints seem to show that it's not rebinding and no unexpected code is running. I know your first instinct will probably be that I'm wrong about the rebinding code not running, but I have literally been staring at the debugger for hours trying to find my mistake. Lots of breakpoints. I don't get it -- this really isn't that complicated. But obviously I am missing something. I've put about four hours into this so far and I think I'm just grinding at this point. I could use another perspective.
HTML (and by the way, DropProtocolCycleID is the problem control):
<asp:Panel ID="PanelPopupAssign" runat="server" Style="display:none; cursor: move; width:325px; background-color:Transparent;">
<BlueUI:Panel runat="server" ID="PanelPatientProtocol" Width="500px" HeaderText="Assign Protocol">
<table cellspacing="5">
<tr>
<td style="width:150px;"></td>
<td style="width:50px;"></td>
<td style="width:125px;"></td>
</tr>
<tr runat="server" id="TableRowCategory">
<td align="right">Category:</td>
<td colspan="2">
<asp:DropDownList runat="server" ID="DropProtocolCategories" CausesValidation="false" autopostback="true"/>
</td>
</tr>
<tr>
<td align="right">Protocol:</td>

So, I have a MasterPage, in which I have an ImageButton and an UpdatePanel. Inside the UpdatePanel I have a LinkButton.
[Code]....
As you can see, both components are asociated to the same OnClick event, which should open said PDF document in a new window using javascript (Code Behind of the MasterPage):
[Code]....
I build the path using the toolTip of the component that has been clicked,which has the name of the file that should load in the
new window.
When I run the application, and click the ImageButton, the new window opens and the file loads correctly. However, when I click the LinkButton, nothing happens (it should do exactly the same as the ImageButton).
If I set a breakpoint, and debug, when I click the LinkButton, it goes to the LnkRelease1 event (as it should), everything looks fine, but it doesnt open the new window, It doesn't execute the javascript window.open.

when I try to change the Behavior component's id in $create() I receive an exception when running the web page with the component control on it:
Microsoft JScript runtime error: Sys.InvalidOperationException: The id property can't be set on this object.
how then to change the Behavior's id? I know it is impossible to change the id of a Sys.UI.Control component, but the web control I created has a Behavior client side API.

I'm using SliderExtender in content of a Master Page.
It has a JavaScript function that is called in both $(document).ready and Sys.WebForms.PageRequestManager.getInstance() .add_endRequest() .
When I initial the page, the function is not active, it says " $find('BehaviorID') " is null, while other JavaScript function (without behaviourID) works smoothly.
But when I do a postback on the page. The slider function turns to available.
It seems the page didn't generate properly, miss a slider tag with class = "...BehaviorID..."

I've got a user control that is displayed via a PopupControlExtender. The user control is a GridView that dynamically adds columns to the control to display the results of a SELECT statement. The PopupControlExtender correctly displays the control and the control displays the neccessary columns. However, when the control is first displayed, the column widths are ignored, despite that they are explicity set. If the control is displayed and then hidden, the column widths are acknowledged the next time the control is displayed.
Here's the user control when first displayed

I have a 'MaskedEditExtender' textbox for phone number on my application. On IE, when someone clicks somewhere in the middle of the textbox using the mouse, on the first click the cursor is actually placed at the first digit of the number. On the next click positions it is at the mouse position. However, on other browsers like Chrome, Firefox, etc.. on the first click of the mouse, the cursor position is at the mouse position (not at the first digit of the number). There does not seem to be any special code written to specify this behaviour. Is there a default behaviour for 'MaskedEditExtender' on IE which results in this?
