I have a ModalPopupExtender that I call when the user click on a button. In the popup, I have a textbox where I want to put today's date, but I only want to do it when ModalPopupExtender shows (or when the user click on the button). The problem is the click event of the button isn't fired on server side when I clicked on the button and ModalPopupExtender doesn't have any Show event.

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'm going to do a project soon for a photographer. There will be a number of pages that will have a photo album or slideshow on them. I'm trying to figure out the best way to have this site perform well and the best way to get the images on the client in the background.
I'm hoping to have the slide shows for the other pages load in the back ground after the home page loads. I thought this would not affect the loading of the home page and decrease the amount of time it would take for the other subsequent pages to load.
AJAX seems like a good fit for this with the async calls. I'm thinking about using an async call to fetch and cache the other images and/or slideshows.
Is this a good way to do this? Is there a better way of doing this? Would it be better to have anew thread do the caching to the client?
I have web page with multiple update panels on it, each update panel has a detail view which is bound to different data sources, since the data loading takes time so i want that when data from any source is available the update panel shows it, while the other update panel shows a progress panel till data loading is done.
I have set all the update panel to 'Contional Mode' updating and a trigger is set to them against a buttons click event. on button click i load data from Db. hoever, when i click the button all update panel start the progree bar and they load data syncronously, but i want the above secario.
The Calendar shows up when you click in the text box. And when it shows up it has no background. It is just letters and numbers, you click a number and that one appears in the textbox. I cannot use ToolkitScriptManager because the AjaxControlToolKit.ddl I have is old, I am afraid to download the newer version because this is for work and they told me to use that specific one. here is my code:

My setup is as follows: I have 4 tabs of data, all of which are invisible when the page loads. The user enters some search criteria, hits the search button, and then the first tab fills up a gridview with data and becomes visible. One of the columns in this grid is a linkbutton named 'detail'. When they click on 'detail', the 3 remaining tabs go and get their data from the database and become visible. On tab#2, I have a listview which allows editing/adding of data. Here is my problem: When I click the imagebutton on the listview that puts the listview into edit mode, the data from the first tab is now shown on the second tab.
So the correct tab (tab#2) remains selected, but the other tab's data is being displayed. Has anyone else run across this? I have tried numerous combinations of update panels and triggers but I always get the same results. Also, the last 3 tabs each contain a usercontrol. I don't know if that has anything to do with it.

Why calendarExtender shows dirty calendar for the first time? (see the image) How to fix it?
View 2 Repliesi use Ajax extenders such as Modal popup and onMouseHover on couple of my aspx pages.

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:

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:
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?
