Is it possible to do things in a PHPish way in ASP.Net? I've seen <%= %> but I've tried it and couldn't get it to work. The PHPish equivalent of what I want to do is
<script src="<?php echo ResolveUrl("jquery/js/jquery.js"); ?>"></script>
The inline code
<% for (int i = 0; i < ThumbnailList.Items.Count; i++)
{ Response.Write("thumbnailViews[" + i.ToString() + "] = $find('" +
ThumbnailList.Items[i].FindControl("ThumbnailView").ClientID + "');
"); } %>
produces a bunch of compile time errors in Visual Studio 2008 - although it works fine.
But this seems to be the exact way inline code should be added, at least according to this MS help file:

The errors are:
expected expression (at "<%")
expected ';' (at "int i")
expected ')' (at ThumbnailList.Items.Count;
expected ';' (at " i++)")
I have done a
<%@ Page Language="C#" ...
at the top of the file.
How 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.

How to Use a Variable Defined in Code Behind File on inline code for same page..
View 7 RepliesFor reasons that are probably not worth mentioning in this post, I have decided to stop using ASP.NET controls and simply use regular HTML controls for my .aspx pages. As such, to dynamically generate HTML, I use c# inline to the .aspx to do what I need to do.
For example: this .aspx snippet shows how I am dynamically creating a <select> element where the <option> elements are driven by looping through a generic list of objects.
<select name="s">
<option value="-9999">Select an entity...</option>
<% foreach (MyEntity e in this.MyEntities)
{%>
<option <% if (MyEntityInScope.ID == e.ID)
{ %>selected<%} %> value="<%= e.ID %>">
<%= e.Name%></option>
<%} %>
</select>
Functionality-wise, I prefer this method of creating HTML (I feel more in control of how the HTML is generated vs ASP controls). However, syntactically (and visually), I think it's cumbersome (and ugly).
Is there a "better" way (another syntax) to dynamically generate HTML w/out resorting to using ASP.NET controls?
A question from a non-web-designer about the preferred - and least browser-sensitive - way of shifting users controls a few pixels horizontally and vertically if I'm using divs instead of table cells.
If you look at this top part of a web page, you will notice that the lower menu is a couple of pixels too far to the left and a couple pixels too high. (Note right edge doesn't line up with the menu above it. Also, tops of image buttons to the right of the lower control are clipped.)
Can I position them absolutely, or use white space to shift the lower one into alignment?
Here's a screenshot:
Here is the approximate markup:

Is it possible to do something like this inline in an ASPX page?
<%= Me.SomeExtensionMethod() %>
I can't seem to figure out how to get this to work properly. I'm receiving an error saying that "SomeExtensionMethod" is not a member of the current Page object. I've added the necessary <%@ Import Namespace="..." %> directive at the top of my page. This Does work in code-behind.This isn't vitally important, but it would be good to know how to do in the future.
In code behind, I get a value that I need to pass to my inline code i.e. <%= myStringVariable %>. How do this?
P.S. The value that I'm trying to send is for a third party control's property. Something like this:
<xyz:SomeThirdPartyControl ID="myID1" runat="server" SomeProperty="<%= myStringVariable %>" />
I want to publish my web application as a single .dll file without all the source code and .aspx markup pages.
I am using VS 2010 with the "Web Deployment Project" add-in. In the compilation settings, I unchecked "make this site updatable" because I want the .aspx files to be compiled as well.
Publishing my web application using the publish feature in VS 2010 works fine, and a single .dll file is created in the "bin" directory.
But all the .aspx markup files are still copied to the web server! I've read that those files are merely marker files which can be deleted, but not in my case. They still contain the whole markup and when I delete them, my application won't run anymore.
It's like I had checked the "make this site updatable" option, but I haven't!

I have a CheckBoxList in my page, with the DataTextField and DataValueField attributes set, is there an attribute that I can use to specify a property that indicates if it should be checked?
I'm hoping to just set the datasource, and not have to have any code behind to set the checked property. Possible?
I have created a web user control called Activity. I have defined a public-facing event on that web user control called OnActivityDelete. There is a delete button in the Activity control. When the delete button is clicked, the Activity control fires the OnActivityDelete event. I am using this web user control in a repeater. I assign an event handler to the OnActivityDelete event on the repeater's item data bound event. When I click the delete button for the Activity control, the event fires from the Activity control, but it never hits the event handler in the page that's using the control. (I have stepped into the code with the debugger and confirmed this behavior).
My suspicion is that this behavior has something to do with the fact that the event handlers are added in code behind when I bind the repeater to a datasource, which I only do if the page is not posting back.Is it possible to define the event handler for the Activity control in the markup of the aspx page? If so, will this solve my problem?If not, do I have to bind the repeater and hook up to the events every page load in order to solve my problem (this works, I just tested it), or is there some viewstate trick to getting the events to persist?

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've been working on the ASP.NET Development Server recently (on an MVC project and I'm finding that it is inconsistent in how it serves the changes I make to my code. For example, I make a change to the C#/HTML/CSS/JS in the dev environment and run the page, and the change appears on the screen. But if I edit the HTML again and run the page again, the new change doesn't appear. Even ctrl+F5 doesn't do it. I have to stop the web server and run the app again for the changes to update. Has anyone else experienced this? Is there a way to sort this problem out?
If I'm working in IIS and I change something, a ctrl+F5 will always update the page with the changes I've made. I'd like the dev server to be as reliable.
