postback

I am using ASP.NET. There is a system that needs to POST data to my site and all they asked for is for me to provide them with a URL. So I gave them my URL http://www.example.com/Test.aspx . Now I do not know exactly how they POST it but now on my Test.aspx page I need to write code that will save that data to a database. But how would this work and what must I do on my Test.aspx page? I wrote some code in my Page Load Event that sends me an email on Page Load to see if they actually hit the page and it does not seem like they are even? You can get a form value posted to a page using code

I have a div within an aspx page with overflow set to auto. The contents of the div are dynamically created and consists of a list of link buttons. <div id="div1" style="overflow: auto; height: 100%;"> ..... </div> When I scoll down in the div and click on any of the link buttons, the page reload loses the scroll position inside the div and takes me to the top of the div. Is there any way to prevent that? Note that this is for a div inside the page. Page.MaintainScrollPositionOnPostBack() does not work. As Jeff S mentioned one way to handle this situation is using javascript to track the

I have a ASP.NET button but recently, I replaced it with a standard HTML button ... What I need to do is a postback to an ASP.NET page and ensure a method is called. The previous button was an ASP.NET button, so I had this event: Protected Sub btnCancelar_Click(ByVal sender As Object, ByVal e As System.EventArgs) UtilTMP.DisposeObjects() Server.Transfer("~\Forms\test.aspx", True) End But I was using a button with a JavaScript ALERT and I recently changed to a jQuery UI Modal dialog but it doesn't wait for me to answer the question.. the postback happenes immediatly ... so I decided to change

A common web problem is where a user clicks the submit button of a form multiple times so the server processes the form more than once. This can also happen when a user hits the back button having submitted a form and so it gets processed again. What is the best way of stopping this from happening in ASP.NET MVC? Possibilities as I see it are: Disable the button after submit - this gets round the multiple clicks but not the navigation Have the receiving action redirect immediately - browsers seem to leave these redirects out of the history Place a unique token in the session and on the form -

I am using ajax and asp.net. iI have a javascript function which creates many other javascript functions with setTimeout. After asynchronous postback happenes, I want to disable all of these setTimeouted events. How can I do that? Nick Craver When you call setTimeout() , store the timer ID so you can clear it. If you're creating many timeouts, then an array is a good option for storing the IDs. For example: var timeouts = []; //then, store when you create them timeouts.push( setTimeout( { ... }, 1000) ); Then when you want to clear them: for (var i = 0; i < timeouts.length; i++) { clearTimeout

I keep on hearing this words ' callback ' and ' postback ' tossed around. What is the difference between two ? Is postback very specific to the ASP.NET pages ? Andreas Grech A Postback occurs when the data (the whole page) on the page is posted from the client to the server..ie the data is posted-back to the server , and thus the page is refreshed (redrawn)...think of it as ' sending the server the whole page (asp.net) full of data '. On the other hand, a callback is also a special kind of postback , but it is just a quick round-trip to the server to get a small set of data (normally), and

I'm trying to use the ImageButton control for client-side script execution only. I can specify the client-side script to execute using the OnClientClick property, but how do I stop it from trying to post every time the user clicks it? There is no reason to post when this button is clicked. I've set CausesValidation to False, but this doesn't stop it from posting. Here's one way you could do it without conflicting with the postback functioning of other controls: Define your button something like this: <asp:Button runat="server" Text="Button" UseSubmitBehavior="false" OnClientClick="alert('my

I have a web form with a detail and a list view on it, the user fills the data in the fields of the detail view and then presses the "save" button, and everything is ok for the moment. However, if they press F5 after this operation a new record is going to be inserted in the DB, because the postback is repeated. Does anybody knows how this could be avoided? This will be the same for any webpage that uses a POST request for its operations. You could stop this by using Response.Redirect("yourpage.aspx") after your save button event. This will send them to a fresh version of your page without

In asp.net page I need to know how to maintain the value of a particular label assign by the html button click. After postback done. Detailed code: <table> <tr> <td><asp:Label ID="lbl1" runat="server" ClientIDMode="Static">Before Changing</asp:Label></td> <td><asp:Label id="lbl2" runat="server" ClientIDMode="Static"></asp:Label></td> <td><asp:TextBox ID="txtbox" runat="server"></asp:TextBox></td> </tr> <tr> <td><asp:Button ID="btnasp" runat="server" Text="ASP Button" Height="50px" Width="150px" OnClick="btnasp_Click"/></td> <td><input type="button" id="btnhtml" value="HTML Button" onclick=

I noticed recently in my ASP.NET web application that if I set my User Agent to an empty string (using a FireFox plug-in to spoof the user agent), then ASP.NET will not generate the javascript required to perform postbacks. More specifically, if you try calling the __doPostBack(a, b) function from your javascript, you will get an error saying that function is undefined. I understand that every browser has a user agent, so this won't come up that often, but the essence of the problem still exists: there are cases in which an unrecognized or malformed user agent can render your web application
