I'm wanting to insert some javascript in the body of a page using ClientScript.Register..() when a user returns to it (either by back button or on link click). When I use the back button the inline server script is never hit in debug. Any way to get the server to evaluate the code every single time the user is directed to that page.

I have to use inline code for an aspx page and I need to use a custom server control that is defined in the same aspx page but the control does not get processed as a server control. it gets returned as is as static html tag.
View 3 RepliesHow can I achieve the desired effect?
Here's the code:
<% if(!String.IsNullOrEmpty(%><%#Eval(Container.DataItem,"OrderXml");%><%)){ %>
etc., which is placed inside of an ItemTemplate inside of a TemplateColumn. In the CodeBehind page I will bind a value to the OrderXml field, which occasionally is NULL.
Unfortunately I get compilation errors.
Is there a way to trigger a piece of code to execute at a certain time once a week?
I basically want my website to send out a reminder email every sunday. I have a function called SendReminder() and I would like to know if it is posible for it to run by itself because at the minute I have to press a button to run it.
I have a page with a Textbox, a Button and a Label control. On Button_Click event , I store the value of Textbox in a variable called S using code behind.
I want to show the value of S in the Lable control using inline code but not using the code behind. ?
I've been using code behind files since day one. Now, I have this funky example that uses inline code. How do I use inline code that needs to be executed in Page_Load() while VS still gives me a code behind page? Do I remove the Page_Load event from code behind file?
View 2 Replies<form id="form1" runat="server" method="post" action="Default.aspx?id=<%= ID %>" >
Ok, it is very ugly and I wouldn't have ever tried it myself. It came up in some code that was written years ago but had been working up until this weekend after a bunch of updates were installed on a client's web server where the code is hosted.
The actual result of this is the following html:
<form name="form1" method="post" action="Default.aspx?id=<%= ID %>" id="form1">
The url ends up like this:
http://localhost:6735/Default.aspx?id=<%= ID %>
Which as you can see, demonstrates that the "<" symbol is being encoded before ASP.NET actually processes the page. It seems strange to me as I thought that even though it is not pretty by any means, it should work. I'm confused.
To make matters worse, the client insists that it is a bug in IE since it appears to work in Firefox. In fact, it is broken in Firefox as well, except for some reason Firefox treats it as a 0.
Any ideas on why this happens and how to fix it easily? Everything I try to render within the server control ends up getting escaped.
Edit
Ok, I found a "fix"
<form id="form1" runat="server" method="post" action='<%# String.Format("Default.aspx?id={0}", 5) %>' >
But that requires me to call DataBind which is adding more of a hack to the original hack. Guess if nobody thinks of anything else I'll have to go with that.
I have a form in vb 2010 with multiple image buttons displaying images. My problem is that when I click on a button the page automatically returns to the top of the page(the image is displayed). The me.button.focus() code causes the page to load on top of the displayed image. Is there a way to keep the focus on the button while the image is being diplayed at the same time.

In my stored procedure there are 8 queries for 8 tables.Each query has joins and sub queries. I am passing parameters & stored procedure name from front end(designed in asp.net 3.5) can we execute that 8 queries at the same time i.e. parallel execution so that I can minimize stored procedure execution time?
View 6 RepliesSo I have a repeater which binds page numbers. That's all fine. I need to know how to make the paging so that they are in "chunks" of a max of 10 page numbers being displayed at a time.Then if they select a page number, it will show the previous x pages and the next y pages (within the 10 chunk range). similar to google paging I guess. Not using pagedDataSource/gridview/gridlist! This is just purely getting the page numbers.
View 1 RepliesI have an ASP.NET website that worked fine using and debugging in VS2008. I went through the upgrade process opening the solution in VS2010. I can run the site, but as I make changes in the app_code folder classes, they don't seem to commpile and warn me of compile-time errors. As soon as I get to a point that calls the class, the errors show up. Sounds JIT I guess, but this isn't how it was working in 08. Is there an option that was changed in the upgrade process? This is a large project, I really don't want to break something and not find out until some obscure page is opened.

View 3 RepliesI have some code I only want to execute the first time I display a form. With this in mind I created a class variable which I initialize the first time I execute page load.

I then select a value from a drop down list , but when it does the auto postback it executes page load but my class varaible has been reinitialized to null and will then execute the code I only want to execute on the first run. why my class variable has been reinitialized.

View 4 RepliesI have developed a User Control in inline code model and convert this into dll and try to add it into Visual Studio ToolBox. It shows error "There is no component found in the object.". It is showing actually because i have not added ToolBoxData attribute just before the class declaration, because there is no class declaration in the inline code model. I don't know where i have to add ToolBoxData attribute.
View 1 RepliesI have a button where I use an Animation Extender. When I click the button I have to set OnClientClick="return false;" otherwise the Animation Extender closes.
So that causes my problem. How do I execute server side code from this button?
I have tried this code in my code behind, but there is an error:
Code:
Dim strScript As String
strScript = "<script>"
strScript = strScript & "return false;"
strScript = strScript & "</script>"
ScriptManager.RegisterStartupScript(Me, GetType(Page), "MyScript", strScript, False)
This is my code for the Animation Extender:

I'm running an ASP.NET ver 4.0 website on Windows Server 2003. Everything was working fine, until I uploaded a new version of the site tonight.I have a new version of the website on my local box, with so many changes that I decided to remove all the existing files on the live site, with the exception of the web.config.Then I uploaded all new files (except the local version of my web.config) from my local box to the live site.
Afterward, when I browsed to the site and tried to use the standard Account/Login.aspx page, all my server code in the code-behind file was displayed in the browser!What would cause this? It *seems* like that would be a server-configured issue, but after I rolled the website back to the old files, everything worked again!
I'm trying to understand how to execute AJAX animation on an asp button that has to execute code on Postback. In other words, I have button with code behind that needs to be excuted, but at the same time want to be able to have one of animation extenders be applied to it. I understand that I need to use the BeginRequest Event, I'm just not sure how, or which javascript commands to use to call the ajax animation so the postback will still occur.
View 5 Repliesi am not sure if my design have flaw but would like to know what others have to say, i am in a situation where i am trying to acheive two things in one click.
using : asp.net web form
i have a web form with few textbox and a gridview control and a button.
if i click on the button i am executing two things
1) asynchronously get data from server to client (working great) and able to display the data in the textboxes.
2) same click i want to bind the gridview.
[Code]....
recap:
1) jquery script execute asynchronously to get data from server to client and display in the textboxes
2) server side code to bind the gridview.
PROBLEM:
if i have onClientClick="return LoadDataById(); then it executes ONLY ajax code and does not execute server side but if have onClientClick="LoadDataById(); then it executes client and server but textbox value wipeout. (the textbox value popuplate through ajax)
When a user clicks a button I need to create a .bmp file on the server. After the .bmp file is created I will load it into the html page. Would Ajax be the best way to accomplish this?
View 6 RepliesExecuting Server side code using Javascript. Here is the solution.In the Asp.net forums, I often see the question asked, "Can I call server-side code from the client/JavaScript?" Almost invariably, the responses given are "No, the client cannot access the server," or "You can only use WebMethods or PageMethods." The first response is not entirely correct, and unfortunately, WebMethods and PageMethods are static methods and therefore have no way to directly access the page.This is why I present to you the following "hack". I call it a hack because there really should be some way built into the ASP.NET AJAX Extensions that allow this approach directly. Instead, it relies on using controls in a manner that they aren't necessarily intended in order to obtain the desired result. But this "hack" does have a redeeming quality—it's incredibly easy.The Code:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default2.aspx.vb" Inherits="Default2" %>
