AJAX :: Modal Popup After File Download Dialog Window?
Jun 23, 2010
I 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 have a button Import on my page. Upon pressing this button, a modal popup dialog appears where the user can enter path of the import file. I have a required field validator to make sure the user entered the path. And I have there a Submit button. My problem is that validation happens not only when I press the Submit button on the modal popup, but also when I press any button on the page itself, which is wrong.
I am trying to get a modal popup inside a modal popup?, also i want to fire the modal popup on a condition in a text change event of a textbox?...is this possible and can anyone give me directon on this
I'm using the ASP.Net Validation controls and I want to display the Validation Summary in a JQuery Dialog instead of the native javascript alert messagebox. I've found this solution (aspsnippets) by overriding the clientside WebForm_OnSubmit() function:
The WebForm_OnSubmit() function is being rendered by the BaseValidator control and in the form tag te following attribute is being added: onsubmit="javascript:return WebForm_OnSubmit();
I am running into a problem on a page which has an UpdatePanel. The input field with the validator (1 to make it simple) is in a Panel within an UpdatePanel. The Panel is set to Visible=False at the first Page Load. There's a button inside the UpdatePanel which makes the Panel with the Validator Visible.
When this happens, the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag are not being rendered because it's an AJAX callback and the form tag is outside the updatepanel (in a master page), so the validation summary will not be shown in the jquery dialog.
Validation is being performed, so the validation summary wil be shown in a div on a page, but the validation is not being called by the WebForm_OnSubmit() function in this case, because it's not being rendered.
So, when the validators are not visible at the first load and they will be made visible by an AJAX callback, the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag are not being rendered on the pag. Because of that, the WebForm_OnSubmit() function will not be called and the validation summary will not be shown in the JQuery dialog (although it is being shown in a div on the page). How can I get the Validation Summary to be shown in de JQuery dialog in this case?
Is there another function that has to be overriden for this case? I know I can use a Full Postback for the New button and then all the stuff needed is being rendered on the page, or I can make the panel not visible by using a style, but I don't prefer that because there are a lot of pages with this situation.
One solution is to use a dummy textbox with a dummy validator (with a dummy validationgroup) of which I set the display to none. Then this dummy validator will cause the the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag to be rendered.
I wish to do a modal popup window. I am new to AjaxControlToolkit. provide tutorial links explaining the necessary things to do this in a step by step manner.
I'm trying to use the modal popup window extender to display a 'loading' icon when the user uploads a file. I'm using the following:
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(beginReq); Sys.WebForms.PageRequestManager.getInstance().add_endRequest(endReq); function beginReq(sender, args) { // shows the Popup $find(ModalProgress).show(); } function endReq(sender, args) { // shows the Popup $find(ModalProgress).hide(); } //END -- // on the .aspx page <script type="text/javascript" language="javascript" > var ModalProgress = '<%= modalProgress.ClientID %>'; </script> <asp:Panel ID="pnlModal" CssClass="modalPopup" Style="display: none" Width="233px" runat="server" > <img alt="Loading Icon" src="../images/redLoading.gif" />
The file is being uploaded, depending on the number of records this may take up to a minute.
</asp:Panel>
which I found on Berseth's site but I cannot get it to work. 'Null' error when it's trying to pop the window. Does anyone out here have another way to do this.
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 -
I have created list of thumbnail images in datalist and on clicking image i want to pass image name to Ajax control toolkit Modal Popup window which display bigger image.
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 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 ..
I want to know, if its possible to pass collection between pages. I mean to say i have a client-side JavaScript modal dialog on which I want to use my collection. Earlier I was using Session[] to share the value, but its becoming evil for me, as it always displays the first value. Any change in value in not updated.
So whenever my pop up is displayed I want the collection to get moved to the Child dialog. From there, i will extract the Collection, do some stuffs and again return it to parent page, preventing postbacks and session management.
I have a parent window from which i open a modal dialog on button click. In WinXP with IE8 it works just fine, but in Win7 with IE8, upon opening the modal dialog it brings me to the login screen. If i enter my credentials, close the dialog and open it again, it works.The explanation i figured out is that the session isn't transfered between parent and child.The modal is opened with javascript window.open function.I don't want to store the credentials in a cookie and then read it in my modal because it's a security no-no. Is there an explanation why this is happening in Win7 and not in XP and is there a resolution for this issue?
I have an Ajax ModalPopupExtender on a page. To summarise. I have a link on a page, when I click the link the modal popup displays. On this modalpopup I've a textbox and an 'ok' and 'cancel' button. I wish to find out what was entered in the textbox when the button is clicked I try this but the value of ((TextBox)button1.Page.FindControl("theTitle")) is null.
if (((TextBox)button1.Page.FindControl("theTitle")).Text == "") void okButton_Click(object sender, EventArgs e) { try { //if i try this tt does not compile//The name 'theTitle' does not exist in the current context//if(theTitle.Text == "")//{//} Button button1 = (Button)sender; //TextBox theTitle = ((ImageButton)(e.Item.FindControl("theTitle"))); if (((TextBox)button1.Page.FindControl("theTitle")).Text == "") { } else { } } catch (Exception) { } }
I have a bootstrap modal pop up that contains Last Name, First Name and Middle Name. And it is inside the update panel alse the button submit. The button submit is triggered as Asynchronous Postback. But when I click the submit button the background of modal pop up is still there.
I have a parent window from which i open a modal dialog on button click. In WinXP with IE8 it works just fine, but in Win7 with IE8, upon opening the modal dialog it brings me to the login screen. If i enter my credentials, close the dialog and open it again, it works.
The explanation i figured out is that the session isn't transfered between parent and child. The modal is opened with javascript window.open function.
I don't want to store the credentials in a cookie and then read it in my modal because it's a security no-no. Is there an explanation why this is happening in Win7 and not in XP and is there a resolution for this issue?
