Web Forms :: Postback On Iframe Click With HTML Page Inside
May 19, 2010
I have an iframe in .aspx page , in which i open an html page(local) and I want to postback my .aspx page when user click on an img( that is in html page ) and get that image id on server side.
I have a default.aspx page with an iFrame that displays another "main.aspx" page.
The main.aspx page has some buttons and other controls .. and some events associated to page load and so on .. When i open main.aspx in a browser, evrthg works perfect .. but when i open up defaults.aspx , evrthg loads correctly, but if i click on any button inside "main.aspx" , nthg happens .. and none of the events is triggered ..
I have a aspx page, in that page i have an Iframe. In the Iframe i do some stuff in code behind and when it is done I would like to do a postback from the aspx. In other words, Is it possible to do a postback programatically from the code behind of the iframe to the parent page?I think a postback can be done using "ClientScript.GetPostBackClientHyperlink(New Control(), String.Empty)" but that will only do a postback for the iframe i think.
I'm reading an invoice dataset and building a html table with checkboxes and textboxes in it, and I put that code in a postback = false block, then i got a button and a literal. The button click will loop through the html table checkboxes to calculate a total and assign it to the literal and display it. I got everything working except one thing, every time i click the button, the html table refreshes and lost all the value in textboxes....even though I put the html building block in the postback = false block,it seems like it still won't preserve the values in the textboxes once there's a button click...Anybody knows a solution to that? I want the textboxes keep what values are there.
Im looking for a way to redirect to another page, when i click a link in the iframe. i dont want just the iframe to redirect, but the whole window.
is this possible?
preferably in javascript or in asp.net if possible
EDIT: When i try the answers i get redirected to the source of the iframe, not to the source of the site the iframe lies on... Ill show you the code
function redirect() { window.top.location.href = "./Nyheter.html"; }
As i dont want the code to be static, so that i can use it on many pages without changing the url, i want to do it this way, alt. get the url from db... but preferrably this way, Solution? Also, forgot to mention. The pages are not on the same domain, they are on different ones..
I am using Crystal Report on my ASP.NET Fw. 3.5 project. My report contains 100+ pages. When I click on next page button on crystal report viewer control my whole page gets postback to server and then second page appears. This take same time when first time report gets loaded.
i have two web aplications running on different sites.
1. site gets user information and show another website (2. site) in an i frame. but when i do this 2. site session starts again on every page.postback . if i connect to 2. site without 1. site everything works well.
There is one master page in my application. Left side it display menu and right side there is a Iframe where page will be displayed when user click on menu. so entire page will not be refreshed only Iframe will be refreshed.
Everything is working fine for me but I am facing problem when session expire, my loginUrl page display inside Iframe so user is able to see left menu.
I am thinkin that LoginPage should be display in main screen instead of Iframe.
When user cliick on the control before page fully loaded it goes to error page.
Following is the trace.
Execution Error
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
I have a master page homeMaster.aspx and many content pages. However the situation is I have few .html pages. Now when a user clicks on a link the html page should get loaded.inside the master page. The problem is these are .html and not content page with .aspx.
i have an html page and i want to open it in an .aspx.
I need to made some changes in html before i show that in browser , and i need to make them in memory, so i open and load and make changes to my html Page and , now i need to pass that html string to iframe, but i am not able to do dat from code behind, iframe.innerHtml do not work.
I tried to set innerhtml for a div instead of iframe, that works , but here when browser renders html page, it applies my Html page style sheat on my aspx ( where CSS are defined for body ). Means the CSS for body that is in head of my htmlPage , sets on my aspx page.
I'm using iframe for integration of ASP.Net application somehow one of the page closes iframe window and opens in the new window. I went through the code and noticed that postback is occuring two times for this page and it is leaving the control. This page uses UserControl and if I remove the UserControl then it works fine.
How can I use postbackurl with a formview in master detail after I insert an item in the formview which is at the bottom of a big page? The master detail is inside a tab container
i have some textbox that i validate with a customvalidator control (only, and must be, server side function) and i have an imagebutton control for submit.I must stop the postback if there are some errors in the validation function.I set the validation property argumets.isvalid = false in the customvalidator function but doesn't work, the postback continue.i have tried to set the imagebutton property postbackurl = "" in the validation function but doesn't work.
I need to know if there is any server-side function/custom-code available to find out the HTML of the entire page which is causing the PostBack.
I don't want to do it using JavaScript/jQuery but instead do it at server side.
A JavaScript workaround that implements it can be found at this link. [URL]
Reason, Why I need it? I am writing some inline javascript in page which performs some vital actions and supposed not to be tampered by user(hacker). So, when a postback occurs, I would like to find out the HTML of entire page (at server) so that I can verify it (I have already generated the hash code for entire HTML while rendering the page to check it on consecutive postbacks) for non-tamering and then process further.
This is the reason why I need a way to find out the HTML of the page causing the PostBack.
I have page on which I've a login control in which I've a subnit button. The problem is this that when I refresh the that page the submit button or any button that was clicked last before page refresh gets its click event automatically fired.
I'm trying to solve a problem and am open to any suggestions. Here's the situation:
I have a checkout page that has an iFrame that contains a credit card form. The credit card form resides on an external site that is PCI compliant (and it is a requirement that we are PCI compliant so having the credit card form on our domain is not an option). When the user submits the checkout form, I need a way to force the submission of the iFrame form on the server side. This is because I need to wait for the credit card form's site to send back a reply via a web service on my end, which will be passing a token that I save and use later on when the order is submitted. I also will display any validation errors that are reported from the credit card form site, also via the web service.
This all worked just fine in a simulation, but I'm getting permission errors trying to access the form in the iFrame across domains (and after researching this, apparently it's not possible to access an iFrame's document across domains). I need a way to force the submit of the iFrame form on the server side without having access to the form itself. Can this be done? Can anyone suggest an alternative to what I'm trying to accomplish?
