VS 2008 Is There A Way To Force A 'postback' On The Entire Page
May 12, 2010
I'm having a problem with entering edit mode in Gridview. When I click edit, it shows it in normal mode (labels) even though RowCommand does successfully fire.
But I have to click it AGAIN to get it to show the TextBoxes of 'Edit' mode.
How can I fix this? Is there a way to force a 'postback' on the entire page, or re-render a control? (i'm assuming thats the problem)
Here's the pseudo code:
GridView1_RowCommand(....)
If e.CommandArgument = "EDIT" then
GridView1.EditIndex = 5
End IF
End Function
A click of the 'edit' button returns the gridview with the normal labels. Then when I click it again, the TextBoxes show up.
My site has an iFrame that displays content from and second site. I don't control the second site. When a user clicks on a link in the iFrame, I want it to redirect the entire page, not just the iFrame. I've seen solutions for doing this from the iFrame, but I need to do it solely from the parent. I'd prefer to do it in the code behind, but a javascript solution would be acceptable.
How do I go about forcing a TabPanel to fill the entire height of the page? Each of the tabs in the tab control are being populated with different data such that each panel is of a different height. Some of the tabs may only fill half of the page while others may exceed it, which is why I can't simply hardcode the height. I've tried wrapping the <contenttemplate></contenttemplate> inside of a div and set the div height to 100%, but that obviously did nothing.
I don't know why, but even using update panel, my postback method updates the entire page. I'm using a master page with aspScriptManager inside. My ASP.Net code: <div> <asp:UpdatePanel ID="updProva" runat="server"> <ContentTemplate> <asp:Panel ID="pnlProva" runat="server"> </asp:Panel> </ContentTemplate> </asp:UpdatePanel> </div>
The CodeBehind (C#) creating some RadioButtonList controls in my ASP.Net page, I'll post the main function and de Page_Load: createTest function [Code].... Finally, the Page_Load: [Code]....
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.
if there is any config setting or any other way to force the response to be written all at once instead of it being written in multiple packets??The problem is I am using a response filter to edit anchor href's and the html parser (HtmlAgilityPack) strips out the malformed HTML when the framework writes to the response stream multiple times, so enforcing an all at once write would solve this headache.
While writing some web apps with VS2008 there are times I have to do a postback. Such as when I select a certain value in a dropdown, I have to load new data an another dropdown. Well, I was reviewing a web site already written by another company and they did the same method. But when the second dropdown was reloaded with data, the page did not reload. How are they doing this? I owuld love to not have the page reload if possible. All I could think of is they are possibly using javascript maybe to do this?
I have a webpage with a button. If I click the button and enter the event handler for the click event (so I have actually a postback) I want to force a second postback in this event handler.(Background for this weird seeming request is: I change the theme of the page in the button click event handler. To make this change immediately visible I need to pass the PreInit event of the page again.)At the moment I force a "refresh" of the page by redirecting the page to itself:
[Code]....
But this clears all controls on the page as if I would enter the page the very first time. For instance, a textbox already filled out by the user is emptied. But I want only a postback which does not change any control contents.
I'd like to programmatically force a full page postback to occur after an event is fired by one of the child controls. I can't add any triggers to make this work so it will have to be done via code.
I have a login form on the home page of an ASP.NET 3.5 website which for performance reasons needs to be accessed with a standard HTTP connection. Since the normal postback for an ASP.NET page is relative call for the post, it would mean that when the browser posts the values are sent unprotected.
I would like to do one of two things to make this secure:
Force the Postback to be secure to the same page Send the post to a different page using an HTTPS connection
Is there a way to implement option one?
I'm also looking at the Authentication Service, but looking at the URL reference it is using a relative path:
What is the best practice to force the postback Data and ViewState data to be re-loaded on the code behind?
The reason I ask this is, i have one gridview which is generated dynamically and I when it is structure is generated the postback data is already loaded and I want to forse asp.net to reload the postback data once I have my gridView structure is generated.
I've created a UserControl that is dynamically placed onto my page during the Init event. It populates and works great, but I'm left scratching my head at how to retrieve data from it during a postback.
It's effectively a multipick combobox that is manipulated entirely using clientside JavaScript (I'm using jQuery heavily). Inside the control container element, I render an empty DIV element that contains all of the selected items. As the user selects items, I generate DIVs within that container DIV that includes some markup. Of interest to me on the server side are the contents of a couple of INPUT fields.
After selecting an item, the rendered HTML looks something like:
[code]....
I may be completely off track and this may actually be impossible (or a stupid idea). The only alternative I can think of is to emit actual ASP.NET controls and hook the built-in event handlers.
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 am using asp.net 3.5 and use master pages for most of the website. I need to make sure that users after they logout are not able to use the back button to see in cache data.
I have two checkboxes: cb1 and cb2. They are both hooked up to an onClick event which checks if at least one checkbox is clicked. If this is not the case, it throws an alert and reverts the change. If a legal change was made (e.g. cb2 was checked, followed by cb1 being unchecked), the function calls the server function checkChange() which needs the object and eventargs.
I'm having trouble with the following:
Reverting the change: how can i find out which checkbox was clicked without adding an extra javascript function for the second checkbox? This has to be a scalable solution as more checkboxes may be added later. How do I call the server function checkChange(). I am aware of "this.Page.GetPostbackEventReference" but I am confused as to the parameters it takes.
i'm about to go through my entire site now wrapping that function around every little text variable one by one and it's going to be a huge pain in the butt
i'm hoping there's a way that i could just set my masterpage to automatically run all text through this thing on any page_load, so that the effect would be site-wide instantly. is this possible?
I am showing Custom Error in my page.if somehting happend wrong. but if the same error occured in my subview master page I am not able to show the Custom error page on Entire page its showing me that Error page under subview master page.I am attching the Screen shot.Can any body help me out how to show the Error page on entire page if something happend in any where submaster or other page.Here is the code that I am using in web config file to show custom Error page..
[CODE]...
Here I know the issue what's going on.This issue is occurring because i am using AJAX to partially load the contents of the tabs after the initial page load so the error is occurring AFTER my master page has been loaded.What I need to do is provide a javascript function to handle the error after the ajax call has returned and redirect to the error page.How to write this Javascript and where Do I need to write this?
In my code behind, I use MyParam to query a database and bind the result to a gridview that's inside the MyPanel updatepanel. The updatemode of the updatepanel is set to conditional and in the postback part of the code I have MyPanel.Update();
The updatepanel works fine when I'm doing sorting and paging; only the panel is refreshed. However, when I trigger the updatepanel with my javascript, I see the traffic in firebug showing that the entire page is being refreshed.
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)
I'm making a website that requires ads being repeated down the length of a page with dynamic length. I want the ads to be displayed down the entire length of the page, but I won't know that length until after the data has been displayed. Is there built in functionality for this in .NET? If not, does anyone see any workarounds I could employ to do this for me?
I'm using an asp.net user control with a tree view. When I load the page I want to scrool the user control to the selected node in the tree view. I'm using js function .ScrollIntoView(true). But this is scrolling the entire page (not only what is inside the user control)
here's my code
[code]...
How can I keep the parent page scroll position but continue to set user controll position where I want?
