I am using ModalPopupExtender
as following code.
[Code]....
but btnClose_Click event is not firing. Why? when the user click the close button i want to close the aspz page how?
I 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?
modalpopupextender targetcontrolid firing second time. I dont know, It was working fine. After changing some code. It is working for second time.
[Code]....
I am not using any update panels in my page.
Here is what I'm trying to do: Click a button on my page, which in turn makes (2) things happen:Display a ModalPopup to prevent the user from pressing any buttons or changing valuesCall my code behind method, hiding the ModalPopup when finished Here is the ASP markup:
[Code]....
popup is ALWAYS equal to null.
I've stepped through the code and verified this action. It gets to the end sub and just loops again. Also does it on the production server in IE and Chome (that's all I've tried). Here is the button definition on the actual ASP page:
[Code]....
It goes through the code, sends me an email, gets to End Sub, then loops right back to the top of the sub and goes through the whole thing again, sending me a duplicate email, then exiting normally and sending them to the About page. This is the only code in the aspx.vb besides the class def and inherits statement.
I am performing the search event on the button click and showing the result in datalist inside the model popup on same button simultaneous. but when i am clicking the button it vill not showing the model popup.
<asp:Button ID="btnsearch" Text="Search Property" runat="server" class="btn btn-deault" OnClick="btnsearch_Click" />
<!-- ModalPopupExtender -->
<cc1:ModalPopupExtender ID="mp1" runat="server" PopupControlID="Panel1" TargetControlID="btnsearch" OkControlID="btnsearch_Click"
CancelControlID="btnClose" BackgroundCssClass="modalBackground">

I have a ASPX Page that contains several user controls, which are loaded dynamically after user interaction.
On one of ascx I have a hidden button that is being clicked on some user actions (via button.click()), which works fine on 1st page load. But after the form is being submitted once, the other ascx is loaded. There if user clicks the back button and resubmits the 1st form (again via button.click()), button_clicked event on server does not fire again.
I have a page with in a master page. This page has a user control with a text box and a button. I also have another button on the page. As the page first loads the button_click event on both the controls does not fire when clicking the buttons. I also have an event on the enter key on the text box. This event fires which causes a post back. After post back now my button_click event fire. The button_click event does not fire on the first page_load.

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.
[Code]....
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 read so many post which say if i need to catch the button event on the modal popup extender, i need to use javascript. But when it comes to my requirement I get confused.
I open a data entry form which contains several textboxes, drop down lists, validator controls and 3 buttons (viz. SAVE, SAVE & CONTINUE and CANCEL) on the modal popup. The requirement is that :
1. When the SAVE button is clicked the data in the different controls must be inserted into the database and the modal Popup must disappear.
2. When SAVE & CONTINUE button is clicked the data in the controls must be inserted into the database and the modal popup must be ready for the other with clear controls.
3. When CANCEL button is clicked the modal popup must simply be disappear.
1. I have master page with script manager and contentPlaceHolder. One TextArea is outside ContentPlaceHolder.
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
[code]....
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:
[Code]....
i try to develop a login control with modlpopupextender within usercontrol. i have a problem with hiding modalpopupextender. i indicate that if i put modalpopupextender in aspx page directly it works, but when using in usercontrol it doesn't. my codes are:
[Code]....
[Code]....
i show modalcontrol on masterpage. it is ok. i click btniptal,modalcontrol hides. but after click the btniptal, if i refresh the page(postback) modalcontrol shows again. i said this above that if i put modalcontrol directly masterpage ,thing that i said doesn't happen. how can i solve this.
[Code]....
I have ValidationSummary in masterpage out of UpdatePanel and inside updatePanel i have my ContentPanel. I have an user control where iam having Save button which iam using in all my pages of application. Now i have a requirement like i need to show the validation summary in ModalPopUpExtender.
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:
http://www.laneros.com/attachment.php?attachmentid=185894&d=1290707443
Si alguien me puede echar una mano para evitar esta situación se lo agradecería mucho.
using a modalPopupExtender inside an UpdatePanel (the popup control is a Panel), the popup acts normal (renders on top) using the modalPopupExtender.show() command to display. If you cancel the popup, the next popup will be under the other controls on your page. I have another modalPopupExtender which is not being displayed through the show command but is activated by another control. This one works normally. So something is going on with the show() function inside an UpdatePanel. If I remove the UpdatePanel, both popups work normally.
View 2 RepliesI've been prototyping the use of the ModalPopUpExtender but find that the BackgroundcssClass fills the entire screen even though I have defined the width and height. So when I click on link button the popup fills the entire window and the X/Y positioning has no effect. Other than that the content displays fine. Any thoughts on this issue?

Am trying to get a modalpopupextender working, and it's driving me insane. I can get the popup to show, but it fills the whole browser. How do you set the size of the popup?
Here is my code:

Also the popup is not transparent, how do I make it so. The css I am using for the popup is as follows:
