When I click the button to open the modal popup it shows the popup but then continues and forces a postback causing the page to reload and the modal popup to be hidden again.Here is the markup for the control:
<asp:Button id="LoginOpenButton" runat="server" Text="Login"/>
<asp:Panel ID="ContentPanel" runat="server" CssClass="modalPopup">
<fieldset> [code]....
My script manager has no properties other than the id and runat set.

View 2 RepliesI am exporting a datatable to an excel sheet. When the ExportToExcel event is fire it pops up a "file download dialog" asking if I want to open or save. What I want to do is right after user clicks on open, or save I would like to show a modal popup saying "Do you want to finalize this download?".
Here is some code, it all works except it won't show modal popup after exporting to excel. Why won't mpeFinalizeDownload.Show() run unless I comment out the line above it?

I am using modal popup extender in my web page, it is working fine, but when the page contents are expanded, modal popup displays with no background color. Here is more info -
The web page contains bunch of update panels that have reports in iFrame controls inside it. On click of save, I display modal popup with confirmation message. Initially, all panels are collapsed, modal popup is displayed properly with the gray background color. When i expand all the panels, page gets really huge and modal popup displays no background color (transparant). Below are the styles I am using -
.modalPopupBackground
{
background-color: Gray;
filter: alpha(opacity=50);
opacity: 0.50;
}
.modalPopup
{
background-color: white;
border-width: 3px;
border-style: solid;
border-color: #165EA9;
padding: 3px;
width: 600px;
height: 150px;
}
Here is the modal popup code -
<asp:Button ID="btnHiddenTarget" runat="server" Style="display: none" Text="HiddenTargetControlForModal" />
<ajaxToolkit:ModalPopupExtender ID="ModalPopupExtender1" runat="server" TargetControlID="btnHiddenTarget"

Technical Environment - VS 2008 and AjaxControlToolkit 3.5.40412.0.
I copied the code from this tutorial:
[URL] into a page in a test project.
The problem is that when i push the client side button, it shows the popup and immediately refreshes (reseting to initial state of course).
Why is this happening in my new web project, but in that tutorial's demo doesn't?
I'm using IE7, FF3.5, VS2008, latest Ajax Control Toolkit.
For the past couple of days, I've been scouring the Internet looking for a good solution, but it seems all of the examples I'm finding have one or more drawbacks. I've looked at various javascript, jQuery, and AJAX Control Toolkit ModalPopup code and I'm not yet satisfied. I have a web form that does postbacks to update the database and I want it to run in a window such that the user cannot return to the page from which it was launched until it has been closed. I would also like to be able to refresh all or parts of the launching page from the popup page when needed before closing it.
If anyone has successfully implemented something like this, I would be very interested in seeing the particulars in how you made it work.
I've got a datalist sitting inside a modal popup and i'd like to pass a querystring value to it when the user clicks to open the modal popup.an anyone point me in the right direction?Written w/ C#.
View 5 RepliesI have a asp.net page that has a list of items. When one of the items from the list is clicked a details page is displayed. This details page has a link button to show a popup for history of the item. The details page also has a button with text 'Back'. The back button has onclick event set to "javascript:window.history.back();".
This back button works fine and goes back to the first page. However when the user is on the second page and opens the pop up by clicking on the link button, the back button stop working and displays Webpage has expired message.
when i call modal popup extender the background is scrolling , i want to freeze the background page then is there any properties or any other idea to get this ..
View 5 RepliesModal Popup user control (its a message box) on top of a modal popup with javascript that maintains postback on a scrollable div all inside of an update panel causes my page to flash on postback of the user control. If any one of the peices (user control, modal popup, javascript) are missing everything works fine. The javascript is maintaing scrollback on a scrollable listview on the page. A modalpopup is shown on top of this main page that is for report parameters. The user control is used for validation and is displayed if a parameter is invalid. I know this may not be the best design, but it can't really change unless its a minor change. Heres the js if anyone wants to see popup or styles let me know.
//Begin methods to maintain or reset scroll position during postback.
var controlIds = [];
var scrollTops = [];
//Register a control to maintain its scroll position on postbacks.
function MaintainPostback(controlId) {
controlIds.push(controlId);
}
//Find the div/control id in the controlIds array and set its scroll position to 0.
function ResetControlScrollTop(controlId) {
var index = 0;
while (index < controlIds.length) {
if (controlId == controlIds[index]) {
scrollTops[index] = 0;
return;
}
index++;
}

How to open Popup Window from dropdown list ...... [URL] .... Like this link but open in dropdown selected item.
View 1 RepliesI'm using modal popup extender and panel with calendar in it. Click the "Next / Previous Month" closes the modal popup. How do I tell the modal popup to ignore click events in a calendar control inside the panel targeted for popup? I'm confused because when using extender before, you had to click OkButton or Cancel to close popup. I have update panel for reason. I just minimized the code for easy review.

I'm using AjaxControl Toolkit.
I want to Creat a window which should Display when i run my page.
Window should contain 3 inner windows two side by side and one is below them.
I'm trying with modolPopup Extender.
I have plced 3 panels in side the PopUp panel. But i'm not able to place two panels Side by side..
I am converting across an old popup system from an older app into a newer one and want to take advantage of the ajax control toolkit to do all of the popups.
Unfortunately the business will require me to make the popups look like the old version (essentially just another page opened in a smaller window and showing the title bar). The problem I can see with using the ajax toolkit is that there is no "title bar" that gets included with it as its not really a new window.
I have three modal popup and three link buttons the first link button is on menu i.e. login that shows login-popup and the login popup contains two links forgot password and register both of them opens a popup but the problem is the login popup isnt hiding with click on register or foreget link the popups are appearing perfectly but arent hiding.
The html for all three popup is as shown below:-
<cc1:ModalPopupExtender ID="Modallogin" runat="server" PopupControlID="loginpanel" TargetControlID="loginlink" BackgroundCssClass="modalBackground"
CancelControlID="lnkforgot">
</cc1:ModalPopupExtender>
<asp:Panel ID="loginpanel" runat="server" CssClass="modalPopup">
[Code] .....
And the codebehind file that i wrote some code which also isnt working is as shown below:-
protected void Button2_Click(object sender, EventArgs e) {
Modalforget.Hide();
} protected void lnkregister_Click(object sender, EventArgs e) {
Modallogin.Hide();
Modalregister.Show();
[Code] ....
I also used breakpoints on link click event and are not going to code behind file on click and popup is just shown without hiding the other. And the css used is I found on aspsnippet site!
At the bottom I have couple of buttons that call a modal popup to add new user to a grid.Now when I click on add user button it opens a modal popup. In that modal popup I have a add user control. Aslo In that add user control I have some jquery validations, autocomplete etc.Now when I open my modal popup it loads my user control in modal but none of my javascript is fired. By fired I mean if i start typing in my autocomplete textbox or even validate some fields none of my js is fired. I do have the jquery file included at the top of my user control. This page works fine if i create a simple aspx page and call my user control from there. But somehow when I call it from modal it screws up. Also even if I place a simple alert('Hello') on my user control that also does not fires (just wanted to make sure jquery is not the prob)
