.Net : Link Between Aspx And Code? forums.asp.net

Using VS 2008, I recently imported (Add Existing...) an aspx page (and its aspx.vb code-behind) from a Web App project to a Web Site project. Problem: now, when I double-click on a control on this page, the IDE doesn't open the aspx.vb code-behind. Instead, it does this: 1. Changes to Source view on the aspx file 2. Inserts <script></script> tags near the top of the page's html 3. Creates a stub inside the script tags for the code I'm about to write. Question: Why doesn't the IDE open the aspx.vb file for editing instead? What establishes the link between the aspx and the aspx.vb? Here's some code from these files: ASPX [Code].... Double-click on a control brings me to this: [Code].... ASPX.VB [Code]....

VS 2008 - Converting Between Web Project To A Website www.vbforums.com

I am not sure if I am using the correct terms. But it is possible to create an asp.net website at least three ways. 1) Where the form and code behind code are in the same file 2) Where the form and code behind code are in separate files, resulting in 2 files for each page (*.aspx, and *.aspx.vb) 3) Where you upon the site up as a project, but insert web pages. This approach results in three files per page (*.aspx, *.aspx.designer.vb, and *.aspx.vb) My problem is I have a site which is done the third way and I would like to switch it to the second. Is there any automated way to do this, or do I have to do it page by page. What I can do is Open a new site with Create Website, insert a page, and then do some copy and paste.

Trying To Pop Up A Window Based On VB Code Result? www.vbforums.com

I have a web page where I am hoping to insert a single line of code. This code will execute an aspx page that will determine whether or not the popup should occur, and then if so, pop up the window.In the main page I am using this line of code: <script language="JavaScript" type="text/javascript" src="Check.aspx?sid=2383"></script> When I step through this, the check.aspx page is hit, it goes through the check logic, and returns a value of TRUE. All of the code behind in the check.aspx page is VB. I can step through every line of the code with no problem and see that the return value is true.In the html section of the check.aspx I have: <% If PopTrue Then%> <script type="text/javascript" language="javascript"> window.open('Display.aspx','Display') </script> <% End If%> If I step through the code in Visual Studio, I see the window.open command is being hit, yet the window never opens. This seems very odd. Am I missing something?

Asp.net - Hiding A Parent Modal Popup In ASP / Ajax stackoverflow.com

But now I've discovered a new problem. After the VB code-behind is finished executing on the child page, I'd really like to hide that modal form. Don't get me wrong, I have nothing against modal popups. I rather like them in fact.

I tried ParentForm.ModalPopupExtender1.Hide() Top.ModalPopupExtender1.Hide

Trying to use javascript and ajax to execute the same code my vb had.I put in a script manager, set EnablePageMethods to true, added a static subroutine, and referred to it in my javascript function (BTW -- this seems a lot of work just to execute an existing subroutine).

Originally this code was handled by an ASP/VB button, but the specs have called for it to be deleted.

In other words, both aspx.cs pages (called page1.aspx.cs and page2.aspx.cs) has the class public class CheckValue { //content return true; } Both the aspx pages reference the 'inherits' files seperately: <%@ Page Language="C#" CodeFile="page1.aspx.cs" Inherits="_1" %> and my code behind public partial class _1 : System.Web.UI.Page and for my second page <%@ Page Language="C#" CodeFile="page2.aspx.cs" Inherits="_2" %> and my code behind public partial class _2 : System.Web.UI.Page I don't use the .resx file.

Adding ScriptModule To An ISV Folder In CRM 4.0? stackoverflow.com

How can I make ScriptModule load and work as expected when being accessed through /Orgname/ISV/MyAppName?

How To Load The Webpage One Bit At A Time forums.asp.net

I have an aspx web page, which has a 'frame' (logo, menu bars, etc.) and then the central where all content is under a form/div element. To populate that content I make calls to different servers, and then I display it. I make these calls using the VB.net code behind the page, with several functions that get called from the 'Page_Load' function. The thing is, until all content has been downloaded (that is, all calls to external servers have returned and I can populate the data div), the page doesn't display anything. Instead it stays there, waiting for the response, and when it has all the available data finally renders the page. What I'd like to do, in order to avoid long waits, is to display at least the menu, logo, etc. while the server is waiting for the rest of the data to return. I think this is the way most web pages work, and would like some advise as to how implement it.

I am using JQuery & JSON (POST) to call webmethod. However I can call only webmethod located at aspx file but not in asmx file Below are sample codes CustomValidate.asmx Imports System.Web.Services Imports System.Web.Services.Protocols Imports System.ComponentModel Public Class CustomValidate Inherits System.Web.Services.WebService 'ACCESS VIA JSON <System.Web.Services.WebMethod()> _ Public Shared Function AJAX_Test(ByVal date1) As Boolean... Return True End Function End Class Javascript: JQuery JSON function isDates(source, arguments) { var isValidDate; $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "CustomValidate.asmx/AJAX_Test", data: '{date1: "' + arguments.Value + '"}', dataType: "json", async: false, success: function(result) { isValidDate = result; }, error: function(httpRequest, textStatus, errorThrown) { alert("status=" + textStatus + ",error=" + errorThrown); } }); arguments.IsValid = isValidDate; } It always return javascript undefined error. But if I put the AJAX_Test webmethod in aspx page and replace the url: "CustomValidate.asmx/AJAX_Test" to "mypage.aspx/AJAX_Test". It works fine.
