Posting back a disabled button

Posted By:      Posted Date: August 26, 2010    Points: 0   Category :ASP.Net

Folks, I have a control which inherits from LinkButton and I'm trying to make sure that the user cannot cause mayhem by performing multiple postbacks.  That seemed an easy enough challenge, so I have this code [snippet] on the client:

ButtonClicked: function () {
    if (this._DisableOnClick == true) {
        this.get_element().disabled = 1;
        this.get_element().style.cursor = 'wait';
    else {
        alert('Posting back');

The alert is of course only there for debugging.  If the DisableOnClick value is false, then I see the "Posting Back" alert and, when I click ok, the postback occurs - all good.

If the DisableOnClick value is true, then the "button" gets disabled and the cursor turns into an hourglass - again good.  But the postback doesn't happen - not good.  I assume that the ASP client code is trying to help by preventing the postback when it sees that the link is disabled.

So, how can I either:

  • Persuade the LinkButton to postback even though it has just been disabled; or
  • [probably better] Get my client code to execute immediately after the postback code rather than before.

Browse Button is disabled


I have created a BDC using Application Definition Editor. The connectivity with the Oracle database worked well when setting it up. I was also able to successfully create the BDC Column

But when I try to add a new record, the Browse Button next to Check Names is disabled. What could be the issue?

jQuery modified ListBox not posting back modified values


Hi everyone,

I have an ASP.Net ListBox that I'm trying to populate via jQuery, using the following snippet:

        $("#MyList_btnAddAll").click(function(e) {
        $('#MyList_lstAll option').appendTo('#MyList_lstSelected');

The code has two ListBoxes in fact, one a "source" and the other a "destination".  As you can tell above the ListBoxes are MyList_lstAll and MyList_lstSelected.  These are rendered in the browser as <select> elements, as you'd expect.

The jQuery is working great, the items are moving from one ListBox to the other, the DOM is updated but when I submit this form (not using jQuery), the ListBoxes don't reflect this change on postback. 

I realize my modifications via jQuery aren't available in ViewState but I thought since the DOM was updated these changes would be part of the postback data?  But in the codebehind after postback the ListBox contents haven't changed.  Does anyone know what might be going on and what I can do about it?  Many thanks.

Back Button for Parent Report

Hello all, I have created a summary report and have the hyperlink set up to jump to another detail report. In BIDS, when I get to the detail report, there is an option to go back to the parent report. But when I publish these reports to Report Manager, that back button is not there. Does anyone know a workaround to this? I really want the user to be able to go back to the summary report when they are done looking at the details. We are working on SSRS 2005. Any help would be greatly appreciated.

Web Form breaks after using the browser's back button

I have a web form that allows a user to put some data in a textbox and click a button to do a search on that data.  It opens up a Sql Server Reporting Services report using the data they entered on the previous page.  If they use the browser's back button to go back and enter some different criteria to search on, the buttons don't work anymore. Any ideas or suggestions on what would cause this?   Thanks!

Browser back button issue when ViewState stored in DB.

I implemented the solution of storing the ViewState in DB (since we were getting lots of Invalid & Corrupt Viewstate errors on our site daily) as given in the following website:http://weblogs.asp.net/adweigert/archive/2004/03/09/86628.aspxThe solution was implemented in one of the aspx pages on our site that behaves like a wizard (not using the wizard control though). After starting to store the viewstate in DB, the Invalid ViewState errors were eliminated completely, but I am now facing the following problem:1) User selects radiobutton1 of the two radiobutton choices on Page 2 of the wizard, a postback happens which displays some extra information on the page based on the selection. Now the user hits the next button on the page that also does a postback & displays Page 3.2) On Page 3, user hits the "back button" of the browser instead of the "previous page" button that is available on that page.3) This displays Page 2 from cache in original state(without any selections made). When user now selects radiobutton2, a postback is supposed to happen, but it does not. User then clicks "next" button on Page 2 (a postback does happen here however), & Page 3 is displayed, but it still thinks that radiobutton1 was selected (the original selection that was made in step1) on the previous page & hence displays information accordingly.I am assumi

Mobile redirect and the browser back button

Has anyone here ever successfully constructed a two-page mobile website with VB, one page for input and one page for displaying results?  If so, how do you call the results page and can you return to the input page using the back button on your mobile browser?  I have no problem creating such a website for regular browsers, but I simply cannot construct one for the iPhone or the Droid ... you can't return to the first page via the backbutton and still have it be functional; all you have is the graphics.  There is no load event for the page you're returning to.  It seems like mobile browsers don't handle server-side redirects properly.  If you open a new page via a hyperlink, you can return to the page you were on and it will still be functional; not so following a redirect to another page on your site. I've experimented endlessly with cache settings, redirect parameters, and the pagestatepersister class to no avail.  I need to know if I'm on a futile quest.  Can anyone offer confirmation for can do/can't do?
