AJAX :: ModalPopupExtender Calling .Show() Does Not Work?
Jul 15, 2010
I am using Visual Studio 2010 and working on an ASP.NET web application targeting .net 4.0.I am using the Ajax control toolkit version 4.1.40412.2In my .aspx page I have the following:
[Code]....
In the server side code for the lbAddMember_Click event I have the following:
[Code]....
If I click the lbDummy button the popup will show as expected however if I click the lbAddMember button I can trace the server side code and it is being called but the modal popup does not ever showThis works if running with FireFox but does not work when running IE. Here is the other stange thing. This has been working in IE for last few weeks but just started not working this week.
I am trying to call modalPoupuExtender using url +queryString. which opens fine but when i write some text in textbox and submit. it shows page.isvalid = false.
i commented the page.isvalid the i realized txtbox is empty.
html bit inside modalpopupextender. below is how i am trying to get the value
[Code]....
dim tbx as textbox = TryCast(Me.dvCustomerDetail.FindControl("txtComment"), TextBox)
I am trying to do a simple thing using asp.net. I wanna show a modal popup panel from a server procedure with vb.net.
The error is: The popup don´t show when I click cmdTest Button.
OBS: I used cmdTest just to call the procedure. In my project, one button call a procedure that will or not call other procedure that will or not show the panel.
I have a modalpopupextender and I want to show a panel after a postback which works but once the panel is shown it disappears immediately. Upon reviewing the markup, it seems as though some inline styles are being set.
style="display:none; position:fixed"
If I edit the display attribute and change it to block then the panel will displayed with all its rendered content but I need it to display after a postback. After troubleshooting the only conclusion i have is that the modalpopupextender is setting the inline styles, because when I turn off the modalpopupextender, then the Panel will show correctly.
I have a user control (ascx) vs 2010 that contains a modalpopup extender thats popup control is an asp:panel. In that Panel I have an update panel and a contenttemplate inside the upd panel. It is a pretty simple example of its use, in that I have list box allowing the users to create a new row in a table.
However, when I click targetcontrol, the background changes to the expended modal background, but instead of being able to use the listbox, everything in the content panel is the same as the background and none of the controls on the panel are enabled. In other words, the entire page is loaded dimgray, including the updatearea.
when I click on ImgEnter it show popup menu ModalPopupExtender.Show();
It is correct problem is that when I click on imgcap if it run first ELSE condition it does Session["MessageError"] = true; and it show popupmenu (it show ModalPopupExtender)
I want it just show popup menu (ModalPopupExtender.) just when I click on imgEnter button ....
I use ajaxToolkit:ModalPopupExtender to show a modal window panel. The panel among other things contains a "Submit" button. I would like to call a code behind function on Submit. First I tried this:
[Code]....
But btnSubmitOnHold_Click() is never called. Then I replaced OnClick="btnSubmitOnHold_Click" with OnClientClick="SubmitPutOnHold" and added
<script type="text/javascript"> function SubmitPutOnHold() { alert('blah'); } </script>
I'm using what I believe is a pretty common/boring/generic implementation of a ModalPopupExtender. I'm using client-side JS to show the dialog when the user clicks a link, and hide it if they click "cancel". I only do a postback if they truly want to save the data.
I can click the link to show the dialog, then click the cancel button to hide it, then click the link to show it... ad infinitum. If I decide to save the data via a postback, everything works well, and the dialog is hidden as a result of the postback, all as expected.
However, once the postback completes, my client-side JS show() never works again. Any attempts to click the link fail quietly; no error messages, the dialog just never shows again.
I am using Ajax toolkit first time ... I don't know how to use itÂ
in girdview I am using Ajax :Â ModalPopupExtenderÂ
if I click on studnetid then Student info pop up page should come
 <asp:TemplateField  HeaderText ="StudentID" SortExpression="StudentID"  >           <ItemTemplate  >             <asp:LinkButton ID="StudentIDlinkButton" runat="server" Text='<%#Eval("StudentID") %>'  OnClick="ShowPopupwindowforStudentID" />
I have a gridview that displays items awaiting supervisor approval. The supervisor clicks the Review button and a modal window should popup with the results of a database query on the record. I am using a dataketname param on the grid. Here are the ASPX elements, The gridview and the modalpopup code
[Code]....
I am using mpeApproval.Show() in the codebehind but it isn't firing. I've been at this literally all day and am feeling pretty stupid at the moment. Have I provided enough for you to make a determination?
I have a page with an update contentpanel, with 4 panels inside. Image buttons outside the update panel control control which panel is visible. I am trying to call an animation from a javascript function, but the animation doesn't work, everything else does.
I'm trying to use code behind C# to show a Modal Popup. This is becasue I want to do some field validation on the page, before the Pop-up is shown:Following is the code I use:
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 using in my application the control :ModalPopUpExtenter. In my computer testing localhost, it works fine. But when i put my application on my server, everything works fine except the ModalPopUp.In the page that i use it, my panel is appearing for my user, but i don´t receive any error message.I pute the dlls: AjaxControlToolkit.dll, System.Web.Extensions.dll and System.Web.Extensions.Design in the folder bin.
I'm using a "frame" layout similar to the one in this excellent answer: a div #top at the top of the page, a div#left on the left, and a div #main with the main content. The #top and #left divs contain navigation menus.Now I want to use a popup div using the AjaxControlToolkit ModalPopupExtender inside the content (#main) div.This works fine on IE8 (where #top, #left, #main all have position:fixed), but when I run it on IE6, the modal background only covers the #main div - I need it to cover the whole of the page including the #top and #left navigation divs.
I have a gridview containing a bunch of categories that can be edited by clicking on the respective "Edit" link within the gridview. The modalpopupextender is then shown programmatically (.show() method) and the user is allowed to edit the category. Then the modal popup is programmtically hidden (.hide() method) when the user presses "Update" or "Cancel". For some reason after every new show of the modal popup, the z-index is decreasing by 1000 until it is hidden behind everything on my page. It starts at 7000 for the very first show. Therefore the user would not be able to edit an infinite number of categories if they wanted to.
I want to load an image in a FileUpload control which is inside a panel in a ModalPopupExtender, I'm using a script to view the image before uploading it, but I can not see the preview image, not 'running in modal, this is my code
<script type="text/javascript"> function showimagepreview(input) { if (input.files && input.files[0]) { var filerdr = new FileReader(); filerdr.onload = function (e) {
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:
