So I've got a partial in my MVC project that creates a JSON array. I want to move this chuck of code from the top of the html page body to the bottom with the rest of the JS for speed reasons. That is to say I want to store the JSON created as a string in C# and access it on the Site.Master.
View 4 RepliesWe have several different MVC2 projects on the go and I would like to be able to share a single master page between them.
Is there an easy way to do this without recreating the same master page in each project?
I'm semi-new to writing ASP.Net applications using master pages and I've run into an issue I've spent some time on but can't seem to solve.
My situation is that I have a master page with a structure that looks like this:
<head runat="server">
<title>Test Site</title>
[code]...
When I run this page and click on the image I get an "Object Expected" error.However, if I place the test function into my Default.js external file it will function perfectly.
I just moved to a new PC and installed VS 2010. I copied all of my websites over from the old machine and now when I open the old websites on the new machine, they do not show up in my recent projects list on the start page. New websites that I make do show up there but the old ones do not. This is very inconvenient. Is there a way to make old projects that I open show up in the list?
This brings up another question. Is there a way to make a shortcut that will open VS2010 up with a website already loaded so that I don't have to go through the file open dialog every time?
I'm new to programming in ASP.NET, but I'm making my way through Wrox's Beginning ASP.NET 3.5 in C# and VB.NET.
I'm at a section where I'm creating a BasePage. I successfully created a BasePage by creating a new class file in my App_Code folder called BasePage.cs with the following code:
[Code]....
If I run that code everything works out fine. The page loads and all is well. But, if I try to do the same thing to a page that uses my MasterPage.master file, I get the following error:
Object reference not set to an instance of an object.
Description:
An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Why is that? In the example code from the book (that also uses a MasterPage.master file), everything excutes and runs just fine. But in my test, I get the above error. I've tried comparing my pages to the books included source pages, but I can't find any differences.

How to access controls in master page using javascript? The master page consists of a search textbox, on key down event of the control I call a javascript function writtern inline of the master page. I get the value of entered in textbox in that javascript function. I have tried giving document.getElementById("<%=txtSearch.ClientID %>").value as well as document.getElementById("txtSearch").value. Both display error. I have to access the textbox control from within the master page itself!
View 1 RepliesI am writing an ASP.Net application. I am making use of master page in it. I have several child pages with me, which consist of some java script functions; Let's say;

Now is it possible to call ChildPageFunction() from MasterPageFunction()?
in my default.aspx page i have a dropdown List and a textbox with a submit button below that there are 2 listbox... and the dropdown list holds the names of the listbox
my logic here is to select an item from the dropdown list and put some text in the text box and submit the form which will add an item to the listbox selected.. but when i do this i get an error saying Object reference not set to an instance of an object. i tried to figure out the problem and found that when i remove the reference to the Site Master Page it works fine and when i undo and apply my reference back to the Site Master Page i get the same error.

HOW TO RUN THE JAVASCRIPT FUNCTION ON PAGE ONLOAD EVENT IN CONTENT PAGE OF MASTER PAGE.?
means i have masterpage and the content page of master page namely default.aspx in vb.net
My problem was that .
i wanna run javascript function in Default.aspx and i have called the function
body onload in master page..
when i run my website it shows the error
"" Microsoft JScript Runtime Error : Object Expected ""
The error i get seems to be centered around jquery finding what it's in (window,document, etc.). Right now i'm just trying to implement the jQuery datepicker. the project has a master page, where i placed my script references.
<head runat="server">
<title></title>
<link href="~/Styles/Site.css" rel="stylesheet" type="text/css" />[code]...
I have tried document and window for jquery context, but they both throw the same error.
I have an ASP.Net ListBox that I'm trying to populate via jQuery, using the following snippet:
$("#MyList_btnAddAll").click(function(e) {
e.preventDefault();
$('#MyList_lstAll option').appendTo('#MyList_lstSelected');
});
The code has two ListBoxes in fact, one a "source" and the other a "destination". As you can tell above the ListBoxes are MyList_lstAll and MyList_lstSelected. These are rendered in the browser as <select> elements, as you'd expect.
The jQuery is working great, the items are moving from one ListBox to the other, the DOM is updated but when I submit this form (not using jQuery), the ListBoxes don't reflect this change on postback.
I realize my modifications via jQuery aren't available in ViewState but I thought since the DOM was updated these changes would be part of the postback data? But in the codebehind after postback the ListBox contents haven't changed. Does anyone know what might be going on and what I can do about it?
I want to call a javascript method during page load. I am using application.master of the sharepoint server 2007 as the master page .

I have a javascript function on my Master page, how do I access it with a dropdownlist of a content page. Not from codebehind, I can do that, but from the control itself such as the onSelectedIndexChanged event.

The second question is, how could i initialize(to NULL) my master page value from the content page .
I have a gridview control that extends the default gridview. I have added an attribute called "hiddenSelectedValues" to to the gridview during the "PreRender" event and I have a private variable that points to the value of that attribute.I have some javascript code that modifies the value of this attribute based on the user checking or unchecking checkboxes in the grid. I have confirmed that the javascript is indeed modifying the value of the "hiddenSelectedValues" attribute by using Firebug to see the change as it happens.
However, once a postback occurs, the grid looses the updated value of this attribute and I am unable to reference get the updated value on the server side.How do I keep the value of an attribute changed by javascript on postback?

Is there any reason why registering a javascript file from the head tags of an ASP.NET master page wouldn't work? For example, I have the following (plus many other) file referece:
<script type="text/javascript" src="/js/jquery/jquery-1.4.2.min.js"></script>
but jquery (and every other JS reference) doesn't work when the page loads.
In my project i have used master page.In one particular page , i want a function to be executed on page unload(javascript event) event of that particular page.To achieve this i have written
$('body').bind('unload',function()
{
alert('hello');
} );
But this is not working.This function is not getting called when i move to other page.
I want some drag and drop stuff on my website. I found some javascript that works when using it with a simple html page, but when I tried to put it in my asp site it doesn't.
In site.master (between the head tags):
Code:
<script type="text/javascript" src="~/Scripts/Javscriptfile.js"></script>
and then:
Code:
<body onload="redips.drag.init()">
And the error is:
Microsoft JScript runtime error: 'redips' is undefined
