I am trying to trigger a postback if a certain condition is true. Initially, a user will click on a button on my form, the server does some work, and in the process of doing that work it assigns a hidden field the value of '1'. When the page reloads after that very first postback, I am trying to use javascript to check the hidden field, and if it is '1' I need the page to postback again so the server side can do some additional processing. The reason for doing it this roundabout way is so that I can create controls on the form from my C# code behind as well as download a file in 1 user interaction. Here is what I have so far:
<script type="text/javascript" language="JavaScript">
function atload() {
var HWInfo = document.getElementById('HiddenHW').value;
My page contains a Repeater that is loaded with data asynchronously as the data becomes available, using an UpdatePanel to manage the asynchronous requests.The page contains something a little like this:
The problem being that the LinkButton does not appear to trigger a postback of any kind- there is no visible response to clicking on it and putting a break point on the event listener in the codebehind, it is never triggered. hat the linkbuttons ceased working.
We have a fairly complex content management system where we start with a blank page with just an updatepanel, then in the init function add all the controls, this all works fine.The problem I'm having is that when the loginform control logs in, we get data back from the server that looks like:
I'm trying to prevent data from loading on the page when its needed.
Currently, I check the IsPostBack bool to prevent loading data in my user controls which allows the data to be loaded when the page is initially requested.
However, if my page fails validation and the page is sent back to the user with error messages, my user controls no longer have data in them because the initial request was a postback.
One solution is to have a flag in every user control (IsFailedPostBack) to force them to reload their data. Is there a better way?
It works fine in Firefox but in IE 7 fails doing the postback sometimes. Is it just a problem with my browser? The partial postback inside the update panel works great in both browsers, but when I hit the button outside the panel, the complete postback doesn;t work in IE....
I'm having a really difficult time getting a DataList to work at all. When nothing is bound to the control (this happens before postback) I get an error.
I get the error: DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'Loc'.
I know it doesn't contain a property with the name 'Loc' because I haven't bound anything to the control, which I only do after hitting a Submit button and postback.
How do I get around this so it conditionally evaluates the DataList?
I am looking to incorporate web service into my application but am running into a problem. The following line of code in FwkComm.js document generates the following error: Microsoft JScript runtime error: 'FwkService' is undefined.
I am calling a web service via Javascript. I tried it first in a web page that does not have a Masterpage and it worked perfectly. Then I moved everything over to a web page that does use a Masterpage, and I get a "Microsoft JScript runtime error: Object required" on the javascript statement that calls the web service. My javascript statements look like so:
I have written code to access a text file in another server from my application in javascript. This code works fine in IE but fails in mozilla firefox. Below is the code i have written.
var httpRequest; httpRequest = new XMLHttpRequest(); httpRequest.open('GET', url, true); httpRequest.setRequestHeader('X-PINGOTHER','pingpong'); httpRequest.setRequestHeader('Content-Type','application/plain'); httpRequest.onreadystatechange = function() {alertContents(httpRequest); httpRequest.send(''); function alertContents(httpRequest){ if (httpRequest.readystate == 4){ if (httpRequest.status == 200) { alert(httpRequest.responseText); } } }
To me this should be much easier, but I can't seem to retain the values that are put in the Insert template upon a validation failure or when the sql fails. This will prevent the user from having to retype everything agin in the event of a failure.
As you can see I am using the Sub Insert_Click and not using an insert through the wizard. so the fields are unbound textboxes on the form. There are 2 dropdowns that provide choices for the other fields.
I pasted in the code using the text only option becuase the format was getting messed up. I probably need more background on why the fields are blanking out.
I'm at my wits end on this one looked/Searched/Played/Experimented and I need your help if you can.This page is going to be primarily used on a mobile device using Win Mobile 5 Need to Accomplish:Prevent Postback(serverside) of Page using JavaScript (Postback's slow down the page on mobile device)
First things first.This application is an ASP.NET application using windows authentication.
Situation:The user is logged onto their computer with something like Domain1John and is running Internet Explorer 7 as Domain2Mike using the "Run As" option.
Domain1 is the user's local domain. He is accessing the application over the Internet using the Domain2Mike credentials where Domain2 is the domain that IIS knows about.
I'm opening a new browser page with Javascript, and the window contains a PDF report; the problem is that it is not showing correctly. It shows a gray screen, without even the Adobe reader toolbar.
On the other hand, when IE is run as Domain1John everything works nicely.I think it has something with the local computer rights. I added Domain2Mike to the Administrator group on the local computer, but it still fails to open the new page correctly.
function DoSmth() { var cBox = confirm("Are you sure?"); if (!cBox) { return false; } else { //Invoke validation }
When I push button submit, I call confirm box. If I press cancel - all right. But if I press ok, I need to do validation. How can I stop postback and do valiadation?
In ASP.NET, is there any way that on cue I can cause a partial postback with Javascript in an UpdatePanel?
I tried __doPostBack() but it does a full postback. I can trick it with a dummy button and fire click() then handle the partial postback that way, but I want a more graceful way than trickery.
actually this code is working well in firfox mozila but it's not working in IE8
[code]....
here i want to prevent postback when answerlength == 0 ; but when answer length ==0 then it alert alert("u can't submit blank answer") message and postback to server io want to prevent it how i do ?
but I want to run a JS confirm dialog when the user click it, and if they were UNCHECKING it, I'd like to ask them if they're sure, and if so, postback and run my serverside code. If they say No, don't postback at all.
I have user controls within a master page and within a user control, I may have an update panel. I have the following bit of code I place within a usercontrol that maintains various control styling during partial postback i.e. those controls affected within by an asp update panel.
function pageLoad(sender, args) { if (args.get_isPartialLoad()) { $("select, span, input").uniform();
Indeed, when an update panel does its thing, the Fancy Dan styling is maintained. However, I have one gripe - when a 'large' partial postback occurs, occassionally you'll see the default, generic control styling reappear breifly and then the uniform kicks in to reapply the new fancy styles. Is there any way I can avoid seeing the nasty old, default, bland stylings?
