AJAX :: ModalPopupExtender Hides Behind IFrame?

Sep 10, 2010

I am working with .Net 2.0 using Visual Studio 2005 and the corresponding AjaxControlToolkit .

I have a master page with a ModalPopupExtender that appears some number of seconds before the browser session times out. Everything works perfect, except for one condition. One of the web pages has an iFrame used to display a PDF. If the user is on this page and the modal popup is displayed, the modal popup hides behind the iFrame and the user cannot see it.

AJAX :: SliderExtender Hides Textbox?

Feb 11, 2010

I've tried variations on CSS and layout (such as tables) but haven't been able to solve this problem. I've been able to recreate this with my simple example below on both Firefox 3.6 and IE7. When I load this page, the textbox blinks in for a second and when the slider appears the textbox will disappear. In the case of this example, the slider appears in the place where the textbox tried to load. In other examples I've created the textbox and slider load in different places but the textbox still disappears when the slider appears.


I realize this is an extremely simple example but I'm trying to narrow down the possible places for things to go wrong.

AJAX :: ModalPopupExtender -- Fetch Data In Modalpopupextender

Apr 7, 2010

I would really appreciate if someone can find out what's wrong with this code.

Here is my question. I have textboxes in a modal popup extender (City, state, zip) and there is an image button search for searching the address from the database. All this functionality is within a control (.ascx file). This control is added to the page where it needs to be displayed and is being displayed when a user click the Address button (the code for it is not shown here). The method ShowAddressSearch() in the control is being called from the page and it displays the popup.

When the user enters any of the 3 values and hits search a server event is fired up and the result should be displayed in a grid. What is happening is, when the user hits the search button the server call is made and the data fetched from the db but the modal popup closes itself here is the code for this. I would really appreciate if someone can find out where and how popup is getting closed.

AJAX :: Setting An Unrelated Div To Style:Hidden Also Hides ModalPopup (example Code Included)

On the page is a div id'd as loginBar, and I have a corresponding visibility attribute. Also on the page is a simple modal popup and its controls.The issue is that whenever the login Div is set to hidden, the popup is also hidden. I cannot figure out why the two are linked. It is not the id name of the div, feel free to change it to whatever you like, and I don't believe I have any malformed tags.

Web Forms :: Iframe Dynamic Resize Or Iframe Alternative?

Feb 9, 2011

I have created a web application that docks other web applications into it.When an application is docked the app creates a link button in its "tool box" on the left hand side of the page, users can easily click on any link button to navigate to the desired docked app.

I have a web app that uses iframes to display other web applications inside it. In effect it is a docking application where users can easily access many web applications from within one main app, while staying within the main app. I am having challenges dynamically resizing the iframe based on the size of the application the user is accessing.I have searched the web and tried many ideas but have yet to discover the code that will do the trick.

First, for a docking web application is the iframe the best approach? I have see some posts on ajax but am uncertain how that will help.

Second, if an iframe is the way to do it does anyone have code that will completely liminate the need for iframe scroll bars?

Note:The applications docked in the main we app may be of any size and can change size as users interact with them.

AJAX :: How To Use ModalPopupExtender In UpdatePanel

Feb 5, 2010

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:


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?

this is my final solution:

AJAX :: How To Use A ModalPopupExtender And Set The PopupDragHandleID

Jun 30, 2010

We use a ModalPopupExtender and set the PopupDragHandleID so it can be dragged around the browser.

This works great in most browsers; however one control that is loaded in the ModalPopup is wrapped in a scrollable div, and in Safari when you click on the scrollbar and then move the mouse it starts dragging the modal popup around.

I was hoping someone either has a fix for this issue, OR knows how to detect the browser in either css or javascript and remove the PopupDragHandleID.

AJAX :: Found A Bug In The ModalPopupExtender?

Feb 9, 2010

I think I've found a bug in the ModalPopupExtender. Here is the details:


When you use ModalPopupExtender within an UpdatePanel, the controls in the PopupControl (the Panel containing the content needs to be poped up) will be rendered, even though the NamingContainer (or the parent) of the ModalPopupExtender and the PopupControl is set to invisible. This may cause Event Validation error between AsynPostBacks. Cause

The controls in the PopupControl will not be rendered within the UpdatePanel, but at the bottom of the page outside the UpdatePanel. When the NamingContainer of the PopupControl and the ModalPopupExtender is set to invisible, the content outside the UpdatePanel won't be updated and therefore stays on the page.




Steps to reproduce the problem

Create a simple ASP.NET web application in VS using the code provided aboveRun the app in debug modeClick on button Show 1, and then click the link button Show. The popup panel should show up. Click either
OK or Cancel to close out the popup panel.Click on button Show 2. You will see the content in the popup panel is displayed at the bottom of the page. However, the content should be invisible and should not be rendered, or should be removed from the page.Click on button Show 1 again. You will see the familar error message: Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument...

Further explaination

This error has nothing to do with the ViewState. When button Show 1 is clicked the second time, the page will try to load data (including ViewState, PostData and Session) into the controls on the page before btn1_Click is called. At this moment, pnl1 is still invisible, so the page will only try to load the data for the controls in pnl2. However, if you check the Request.Form.AllKeys in the watch window, the TextBox
txt is part of the PostData. This doesn't match any control in pnl2, and then the exception is thrown.

I have tried many different ways, but none of them worked.
