In our application we have a scenario where we need to display a panel using modalpopupextender after performing an async call on the server. We were using the Show method for displaying the popup. It used to work fine without any async call. But when an async call was introduced during the request processing the popup is not getting displayed.
View 7 RepliesI hava an aspx page with a couple of tables and an UpdatePanel on top of the page. Everything on the page works fine until I show (from code-behind) the UpdatePanel (via ModalPopupExtender). The modal works OK after showing, but the problem is that when I close/hide it (using CancelControlID or a custom button with code behind) some control on the page stop firing events.
More exactly one Button and RowCommand on a GridView (both are NOT part of the UpdatePanel).
Here's the UpdatePanel code:
[Code]....
After this code is all the rest of the aspx page - including the Button and RowCommand that stop firing after showing and closing the update panel.
Where's the error?
I have a modalPopupExtender in my aspx web page pointing to a Panel and in Code-Behind I create buttons which I want them to show the modalPopup, so I have:
buttonX.OnClientClick = "javascript:$get(" + modalPopup.ClientID + ").show();";
but instead it just does a PostBack, even if I put "return false;" at the end of the past code.
I have a DataList that contains some Thumbnail Image(Image Button).
Now I want when i click on any Item in datalist the original image come in modalpopupextender.
How I can do this?

Now where I can to write code that when i click on item in datalist Original Image show in modal popup extender?
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.

I have a modal popup extender with one control (ascx) this control has a label that on onclic method call other popup extender.
It's has other ascx, it's has a button for a search. When I do Click in this button in first time, the event click not fired and there are a javascript error that say "this._activeDRagVisual is null reference".
In the other hand, If a use de second popup inside an asp page the event and control work correctly. The problem is with the popup inside popup.
I have a popup extender that shows when an edit button in a grid is clicked. I am disabling the checkbox and submit button when a particular row is clicked with sone validation. When I close the popup and show again by pressing button on another row the controls are still disabled. Why are these controls properties set permanently on entering the if condition ?

How to write an ajax function to disable a dropdown, until its parent dropdown is selected?
View 1 RepliesI've written a nice page with accordion element in it, but I've found that on some browsers, with some setting- the accordion won'trespond to clicking on it. So, what I get is an accordion that shows headers, but clicking on them won't open the data.What I'm guessing is that the sliding effect is blocked for some reason.What I'm trying to achieve are this two:1. Cancel the sliding effect so the data will show right-away, thus answering the problem caused by some browsers2. Cancel It only when the page detects that there might be a problem. (I'm not quite sure what setting I am looking for).Obviously, 1 is quite more urgent. If 2 is not solved I geuss I can use 1 for all the cases, but still- If anyone could find answer for 1- that would be great.

Disabling Accordion Pane in Chrome Browser?
I have the modal popup come up for searching something. Inside the popup (panel) I have a txtbox and a search button. I enter text and hit 'search' and the results are shown in a listview within the popup. Now every row in the list view has a button "Select". I want to click on one of those buttons to select a particular value.
Now on click of the button(within the listview), I tried calling a javascript function and doing $find('mdlPopup').hide(); , which makes the popup dissappear. But somehow the debugger takes me straight to Global.asax.Application_Error() and doesn't even give me a stack trace to see wht the issue is. And over that, the popup looks dissapeared, but the rest of the controls on the page are not enabled back. Strange?
I'm assuming, that the popup doesn't close as intended and it errored out (which took me to Global.asax.Application_Error() ), and is not enabling the rest of the controls in the page.So my question is, how do I assign multiple buttons in a listview to the okbutton (or cancelbutton) of a modalpopup extender?
I've got a Varchar2 field in my table which I want to convert to a CLOB. I am unsure whether the data would get truncated when selected. If so, what is the limit and does it depend on the database settings?
In my TOAD or SQLPLUS window it gets truncated but this may just be the environment settings. I'm not sure whether it would get truncated in my actual application (I can test this, but up to what size should I test?)
If it does get truncated, what's the best way to display the whole CLOB? There are other fields in my SELECT query, so I think I can't just loop through multiple rows. Is there any way out?
I have a gridview inside a ModalPopUpExtender, the grid view have the button add delete and edit when i clic one of the button of the gridview the popup is closed. I wont to close the popup when the close button is clicked.This is the asp.net part:
< cc1: ModalPopupExtender ID="NamePopup" runat="server" PopupControlID="OptionPanel" TargetControlID="btnD" BackgroundCssClass="mpBg" DropShadow="true" OkControlID="btnSavePopup" CancelControlID="btnPostCancel" >
< / cc1:ModalPopupExtender>
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:
[code]....
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:

View 1 RepliesWe 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.
I think I've found a bug in the ModalPopupExtender. Here is the details:
Problem
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.
Code
Default.aspx
[Code]....
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.
in my c# code i have the following;
ModalPopupExtender2.Show();
This works fine my popup appears, so i put an ok button on the Panel and on_click in the code file i tried to;
ModalPopupExtender2.hide();
But it dosent work - nothing happens. I dont have it in an update panel.
UpdatePanelAnimationExtender in ModalPopUpExtender leads to a white/blank screen in IE. Works flawlessly in FF and Chrome.
I already tested <FadeIn Duration="0.5" Fps="50" forceLayoutInIE="true" />
I am developing a web portal under ASP.Net 4 and using Ajax and masterpage. I created a user control to select a data from a gridview and put it in a textbox, for that use the ModalPopupExtender control. Everything works fine as can be seen in this photo:
http://www.laneros.com/attachment.php?attachmentid=185893&d=1290707244
But after much control to use the ModalPopupExtender starts to appear behind the form and to return to appear before touching refresh the page or press the button repeatedly calling him. In the next picture you can see what it looks behind the popup form:

Si alguien me puede echar una mano para evitar esta situación se lo agradecerÃa mucho.
