.net - Simulate Disable Of Button On Page?
Jan 13, 2011
On an ASPX.Page, I have a button that performs a postback. User must be prevented from clicking it more than once. I want to do this with jQuery but
jQuery(document).ready(function() {
$('#<%= saveButton.ClientID %>').click(function() { $(this).attr('disabled', 'true'); });
});
doesn´t work for me because the button does not postback. Is there an easy way to prevent a second click while still keeping the functionality of the button?

I have one web page abc.aspx It is possible anyway to simulate button click on xyz.htm from abc.aspx? xyz.htm uses form post method, it has 2 radio buttons and submit and cancel button. now from abc.aspx I can open it in new window, but it is possible to select radio button and submit form programmatically?
I personally think its totally illogical and maybe hacking. But someone in my team wants to achieve this. Any comments?

I have the following ASPX page:
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title></title> [code]....
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 know this is strange, and probably considered bad design. I need to simulate the clicking of an actual button on my asp page. I do not need the button's on_click event sub/code to execute. The issue here is that I want to trigger the ConfirmButtonExtender associated with that button. The ConfirmButtonExtender, by design, executes before the Click event code.
So to be clear, I need to actually "click" the button. What the button does is irrelevant (in fact the button is invisible and has no code). I simply need to trigger the button's ConfirmButtonExtender, not the code behind the actual clicking of the button. Like this..
Protected Sub Button1_Click(.....) Handles Button1.Click
Somehow click invisible_button (not call the Click() event, but actually "click" the button)
End Sub
----Long, convoluted details------
I have fields on a page that require user input. When the user hits submit, I want to display a confirmation dialog with the data of those fields.
To do this, I originally added a ConfirmButtonExtender to the "Submit" button (just a regular ASP button). The problem appears because the ConfirmButtonExtender executes before the OnClick event of the submit button.
During my OnClick even I took the data, populated it into a confirm textbox (which is inside a ModalPopUpExtender). I originally then used the MPE.Show() (still in the onClick event) to display my conformation textbox.
However ,the .Show() function doesn't halt code execution (which is needed, since this is a confirmation dialog). So as a result, I created an invisible button.
This invisible button now has the ConfirmButtonExtender added to it, which will display my MPE/Confirm Dialog. When the user hits "Submit", the click routine is called, all the data is stored and populated, and THEN I want to "click" the invisible button, triggering the ConfirmButtonExtender. That will halt code execution in my original Submit buttons click routine.

I have the following scenario and I'm not sure how to go about in resolving it. Any ideas would gratefully recieved.I have a page(A) with a button that when selected opens a new page(B) with a populated gridView.However if the gridview hasn't got any data to display, rather than use the <EmptyDataTemplate> within the gridview, I'd rather use disable/lock the button on page(A) thus preventing access to page(B)Is this possible? How on earth would I go about such a task ?

I have read that you can not disable the back button on page load but I can clear the cashe on page load so the back button would then be greyed out. I have read a few articles on this and I am unable to get it working. I am using MS visual web developer 2010.

How do I disable a button in an ascx page? I know how to do it on an aspx page with:
btnSave.Attributes.Add("onclick",
"this.disabled=true;this.value='Please Wait...';needToConfirm=false;" +
ClientScript.GetPostBackEventReference(btnSave, "").ToString());
But the ClientScript function is not present in the ascx page.

I built a simple application that is used to manage photos for an image gallery on my employer's website. A user can add, edit, or delete items which are stored in an XML file. I've set up Up/Down buttons so that I can move pictures up and down in the order.On the first page, I've disabled the Up button of the first item on the RowDataBound event... since it's already first
[Code]....
I'm trying to do the same for the Down button on the last item of the last

I have four Imagebuttons that I want to disable depending on the Role the user belongs too. I know how do do this in a gridview or detailsview but for some reason it isn't working on just a plain form. So when a User who is not in the "Admin" role logs onto the page he either doesn't see the button or the hyperlink has been disabled thus not allowing him to proceed any further.

In one of my Web Page, there is one Modal Pop up, in which I am using Gridview Edit, Update, CancelEdit, Delete functionality.Main functionality is : If while deleting any of the Gridview Row, if only 1 row remains in Gridview (that row can be any row), then that row should not get deleted.Rest of Edit, Update, CancelEdit functionally is working fine.
I used below code for above:
 C#:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
BindGrid();
[Code]....
problem is: When any last row is left in Gridview, its Delete button is disables that time (as per requirement and functionality). But when user clicks on Gridview "Edit" button, update section opens, and at that time "Delete" button gets Enabled, so that time user can delete the last row of Gridview which should not be done.I had fixed this problem for "Cancel" and "Update" button of Gridview using below line:
Response.Redirect(Request.Url.AbsoluteUri); but unable to fix it for "Edit" button of Gridview. If Last row is left in Gridview , and user clicks on Gridview "Edit" button of that row, then at that time "Delete" button should not get "enabled" it should remain "disabled"

My customer has a website that is unsuitable for children. Anyone under 18 is not allowed ont he site. No, it's not a porn site, it's prison related. A certain page requires the user to enter their birthdate. If they are under 18, they're redirected to another site.
He has another site written for kids who have been impacted by crime. He wants the kids redirected here, to a page that explains why they were redirected. He asked me to disable the back button at this point to keep the kids from easily going back to the original site.
I've read all the reasons why you shouldn't desable the back button, but frankly, I think this would an appropriate place to do it. I also know you really can't disable it, but I've found a number of work arounds - none of which I've gotten to work.
Is there a work around that will work?
I've thought of setting a session variable or a hidden field or an invisible label on the page that redirects the kids just before the redirect and checking the value at page load, but the code to do the checking doesn't get run unless the user hits the back button then refreshes the page. Is there a way to get code to run as soon as the back button is pressed?
