Javascript - To Access An Object Defined On A View In A Master Page In .Net MVC

Jan 12, 2010

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.

Embedded Javascript In Master Page Throw "Object Expected Error"

Jun 8, 2010

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.

Web Forms :: Error When Using A BasePage Along With A Master Page/ Object Reference Not Set To An Instance Of An Object

Mar 6, 2010

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.

Web Forms :: Master Pages - How To Access Content Page From Master Page

Sep 5, 2010

I have a master page setup that is used throughout my site that is basically a header with a menu. I recently added a textbox and a button to this master page which is to be a quick search box that is available anywhere in the site. When a user enters text into the search box and hits the button, I need to load the actual content page which is used to search and show search results (which also uses this same master page), and have the text entered available so the search can be triggered automatically. Again, this search text box and button is now in my master page so it could be triggered from anywhere in the app... it serves as a convenient way to do a basic search from anywhere in my app, without having to first navigate to the actual 'search page' that already exists. You can also navigate to the actual search page, which uses the same master page, where there is many more search options.I'm thrown off by the master page arrangement, which I have not used until this project. What do I do?

C# - Access Object From Javascript DevExpress?

Aug 24, 2010

I wonder why I cant access Object by ClientInstanceName from javascript.

example:

function NextStep(pageControl) {
currentStep = pageControl.GetActiveTabIndex();
switch (currentStep) {
case 0:
selectedRowsCount = GridViewClient.GetSelectedRowCount();
break;
}

The error is:

Forms Data Controls :: Master / Detail Page - Updating Detail Records - Need Access To Master ID (key)

Jul 30, 2010

I have an "Edit" page that uses a FormView bound to an EntityDataSource. The page is called with the ID field of the record to edit in the query string: "EditEmployee.aspx?ID=10". The EDS the FormView is bound to is using: AutoGenerateWhereClause=true and a QueryStringParameter. Below the FormView I have a ListView that contains some child records of the FormView. The ListView is bound to a seperate EDS and also uses the (same) QueryStringParameter.

The problem I am having is when this ListView attempts to Insert or Edt a column I receive an error because I don't have the ID field (EmployeeID) of the parent bound anywhere in the ListView (and obviously, it is setup as a ForeignKey so it fails, like it should). Any advice on the best way to get this ID (EmployeeID) column bound in the ListView? There are many things I can do in code behind, but I would like to solve this in the markup if possible. I can move the ListView so that it is inside of the FormView if necessary.
