I put the following javascript code inline but it doesn't trigger after the updatepanel is done with its postback:
function EndRequestHandler(sender, args) { alert("this should work"); } Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
I have a couple of fields on a form that will be populated with default values. I would like to put a button that will allow me to reset those fields to their default values if they have been modified. However I would like to avoid the postback so that I don't have data being sent to the database. Is it possible to add a javascript hook such that when that button is pressed I can pull the default values and populate those fields in javascript?
I have a page with a ScriptManager / UpdatePanel. I currently need to PostBack to a https page from an http page (different ports). I also need the same session data. Currently, I copy my form to a new form, and when I postback to my new Target on a new Port, I get a crash in xmlHttp..something. I will have to post more details later.
I'm currently wondering if this is possible. And does anyone know of such a fix. I even tried to Turn off Partial Rendering and I still get crashes. I can't do this until I pull out the scriptManager / UpdatePanel.
I have an ActiveX object which extends some functions. I have a web page that loads the ActiveX object and calls its methods in Javascript. The ActiveX object has two method; the problem is that Javascript can successfully call one of them but fails to call the other; citing Object doesn't support this property or method which is nonsense because I made a VB6.0 application that successfully calls this other method, so the two functions are indeed extended correctly and performing their job. And yes, the Internet Explorer security zones are all set and everything, as I wrote above the javascript code can call one method but refuses to call the other.

I have a web form where I define an array of type struct and I redirected it in the <script runat="server"> section of the second web form. But when I use that array below, in the <script type="text/javascript"> section in the html code of the same web form an error occured in the for cycle saying that the array (Array1) is undefined, and also the counter which I also defined in <script runat="server"> section.
I have this code in the <script runat="server"> section of the second web form:
public struct Point1 { public float lat; public float long1; } protected void Page_Load(object sender, EventArgs e) { //Retreive from session Point1[] Array1 = Session["s1"] as Point1[]; //Run a Foreach loop int nCnt = 0; foreach (Point1 p1 in Array1) { float x1 = p1.lat; float y1 = p1.long1; nCnt++; } } and in the <script type="text/javascript"> section I have: var for (var i = 0; i < nCnt; i++) { lineString.getCoordinates().pushLatLngAlt(Array1[i][0], Array1[i][1],0); } lineString = ge.createLineString(''); lineStringPlacemark.setGeometry(lineString);
I've inherited some code which breaks a page up into tabs using divs. On the first page there are many required field and regex validators. The problem is a user can switch to another tab, trigger a postback and fail the validators on the first page, leaving things in a mess.
What I want to be able to do is perform the validation on the first page as a user selects another tab, thus preventing them from moving to a new tab until the first page is valid.
Note use of jQuery for cross-browser compatibility with click event. And this only works if there are no validators on other tabs, as per Thomas' answer, I'll need to use validation groups and extra logic in isValid if any get added.
This an input to a stored porcedure from a web form. My form consists of a text box, 3 listboxes, and 2 more textboxes and a command button. What I need to happen is when the user clicks the command butto it will submit all of the information on the form to the database table. I have a stored procedure in place and the code-behind. What happens though is that the user enters a value into the textbox and hits the enter key and the application will throw an error that expects the next parameter but of course it isn't there. The listboxes postback to grab the data in connection with the value in the first textbox.Here is the code-behind to the aspx page:
[Code]....
The exact error is that it expects parameter @EquipmentType but it is not supplied. It shouldn't be though because the user has not selected anything from the listbox yet. I thought this was straightforward

I have a really massive page/controller which i have been able to code well enough. The user can edit information on this page and wont get it saved to the database unless they specifically say, save. However, there is a list at the bottom of this page that you can add/edit and delete elements. Adding and editing takes you to a different page, and before the page change happens, i want to save the form data to session memory, but i dont know how to access it outside a postback. Can MVC do this?
Is there a simple way to clear the value of server controls on postback? I have tried ViewState.clear() and it doesn't do anything. The page I am working on inherits from a Masterpage that has viewstate enabled.
