C# - Prevent Postback After Opening JQuery Dialog Box?
Dec 8, 2010
Page:
[code]....
This code opens me a dialog box with Ok and Cancel button but it do not wait for user activity and post the page immediately and the label gets populated. I need to call the c# function based on user activity. If user clicks "Ok" label should get populated and if user clicks "Cancel" it should not call the c# function. How do I achieve this?
I am trying to use confirmation dialog from jQuery UI.
I ran into this problem: how to trigger correctly the dialog and at the same time prevent trigger OnClick event specified at button until user click on Yes or No buttons at dialog?
In the example below are two ways how to popup confirmation. Lower one works well. It's a classic JavaScript confirm dialog. When I try to use the jQuery UI dialog, it displays a dialog but allows it to run the event assigned at OnClick (here by using Command, but I suppose there is no difference. Hope I am not wrong.). The piece is taken from the ASP.NET Repeater control btw.
I have a JQuery Dialog that is opened when a button is clicked. The first time around, it should do a postback, but when the dialog closes and I click the refresh button of the broswer, it sends the data again and duplicates the data I just entered. Should I add a return false somewhere so it doesn't postback when the dialog is closed. Here is the script:
I have a jQuery UI dialog which has a usercontrol in it, which I get by .load of the page it is in. It is a simple calculator.You pick several numbers and then click a button, a postback happens and finally you get the result in to two lables.When I click the button inside the dialog, the postback happens and I see the result in the original page, not the dialog.
I have a series of jQuery dialogs that contain ASP.NET form fields. I have a hidden ASP.NET button that is triggered when the user clicks a button in one of the jQuery dialogs. I can enter some data (listboxes and textboxes) and click the button that triggers the hidden button's event (an onClick) and the page will post back.
But, when I put a breakpoint in the onClick event in my codebehind I see that the form fields (reportTypeListBox.SelectedValue, etc.) just have the default values instead of the ones I entered. This happens unless I take the form fields out of the jQuery dialog, then it works perfectly.
I have another jQuery dialog that contains a ASP.NET textbox that is basically doing the same thing (triggering a hidden ASP.NET button with an onClick event) that works properly. The only difference is that its jQuery dialog is not in a seperate javascript function. It's right in the "$(document).ready(function () { }." While, the series of dialogs that are having trouble are in a function called "openDialog(selector)."
When the user click on TreeNew button appears the modal dialog, then he/she choose an option an click Ok button to do a postback.I need that the server side execute TreeNew_Click method: How can I do that?
If I use __doPostBack('TreeNew', '') it throws me the following error: "Object expected".
UPDATE:I found the origin for the error: the function __doPostBack is not defined. I'm not going to delete the question because I think Chris Clark's answer is so interesting.
I think my title says it all. I have a modal dialog showing up and the user can make some changes and then click a 'Save' button. I need that to totally post back the whole page. I just assumed the button would fire off regardless of the jQuery.
I'm having some trouble with jQuery UI. I've created a dialog with jQuery UI: so far, so good. I set up a form inside the jQuery UI dialog and then it's another story. I've written a very simple page to illustrate:
In the code above, see that I've just imported the jQuery, jQuery UI, and stylesheets and set up a page with a dialog box. There is an asp control button1 outside the dialog box and an asp control button2 inside the dialog box.
When I click on button1, the event handler gets called and all is well. However, when on click on button2, the button inside the jQuery dialog, nothing happens.Why is my web page behaving this way?
I have an ASP.NET/C# application that exports some data into an Excel spreadsheet using COM interop at the click of a Button control. When I click the button, Excel is opened with the generated spreadsheet. For what it's worth, here is the button code:
<asp:Button ID="export" Text="Export to spreadsheet" runat="server" OnClick="Export_Workbook" />
This works fine, except when I click the button, close the subsequent spreadsheet, and refresh the page. When the page is refreshed after clicking the button, the call to Export_Workbook() is made again and so the spreadsheet opens again. Firefox, for example, says this when you refresh: "To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier." This is something I want to avoid.
I'm sure there's a better way to accomplish what I'm trying to do, I'm just not sure what the best approach is.
I am making a small file hosting website, and each user can upload multiple files, and will have access to just his files and can't access others files, for example by guessing the URL. Is there a way to secure files to have access by just the owner and no body else "may be website administrator also will have access"

I want to open a CSV file in the client browser "WITHOUT" a save/open file dialoge. I am able to do it with file dialoge but unfortunately I need to do it without it.
im using jquery. is there any way to broke the Dialog popup as diamond shape or any other shape?and how to provide minimize and maximize buttons on the dialog?
The fils containing these control work fine in another project and they work fine on visual studio so I guess it is safe to assume that the problem is not in the files or with the server but has something to do with the project? What could be causing this?
