As far as I know server controls doesn't have a .aspx file. So I need to load a aspx file in order for it to work like a template for my server control, and render my server control content.

I work in VS 2008. Whenver I add a server control(Label) and set it properties in aspx.vb and build the solution, I get the error "Label1 not declared". While analyzing this issue I noticed that the event handler statements for the Label1 where not added in the designer.asp.vb file. These statement would actually be added automatically when I drag and drop a control to my webpage.
I would also like to inform the scenario after which this problem came to me. I was working in VS 2008 , VS 2005 and VS 2003 in the same machine.Could this have caused the issue ?
Now each and everytime when I add a control, I am adding the "With Events" code in the designer page to make my build succesfull which makes me to spend more efforts.
I am developing a C#/SQL ASP.NET web application in VS 2008. Currently, I am transferring control from one ASPX file to another:
if (uploadFile.PostedFile.ContentLength > 0)
{
inputfile = System.IO.File.ReadAllText(path);
Context.Items["Message"] = inputfile; //Page1
Server.Transfer("DataMatch.aspx"); //Page1
}
However, it fails on this Server.Transfer line after inserting runat="server"
in the DataMatch.aspx file to the Table element like so:
<table width="50%" id="tMain" runat="server">
But after making this a server control, I rebuilt it and now when I run this app it gives me exception:
Error executing child request for DataMatch.aspx
But I need this table to be a server control so I can make it invisible programmatically if a certain condition occurs. How else can I programmatically make this table invisible?

I have a async file upload control and I am doing client side validation for Image."OnClientuploadstarted" I am doing the client side validation.My validation is working fine but my problem is that the file upload control text box goes green (i.e file is loaded on the server) even if the validation fails which is I dont want.What I want is when the client side validation fails the file does not gets loaded on the server and the Async file upload textbox does not goes green.I have goggled but have not found a suitable solution.
View 4 RepliesI'm new to writing custom ASP.NET server controls, and I'm encountering the following issue:
I have a control that inherits from System.Web.UI.HtmlControls.HtmlGenericControl. I override the control's Render method, use the HtmlTextWriter to emit some custom HTML (basically a TD tag with some custom attributes), and then call the case class' Render method.
Using the control:
<dc:Header id="header1" runat="Server" DataColumn="MemberNumber" Width="30%">Member Number</dc:Header >
The problem is that when I view my rendered HTML, the server tag is emitted to the client as well (right after the TD tag):
<dc:Header id="ctl00_ContentPlaceHolder_testData1_testData1_header1">Member Number</dc:Header>
How do I prevent this from happening?

I've been watching a video on Scott Hanselmnn teaching MVC 2 tricks/tips. He mentions how MVC 2 by default uses ASP.NET Web Forms view engine to render the output of the views; he mentions that the web forms view engine is a little slower than it could be for MVC 2 since it generates a control tree and then outputs the HTML to the page (I hope I said that right).
I was wondering what he meant by web forms generating a code tree before outputting the HTML to the page. Does anyone have insight on the view engine of Web forms and the steps of the rendering process works for ASP.NET and MVC2?
I am rendering custom control. I rendered the css file on the prerender. When i rendered more than one control in the aspx page, the css will loaded the number of times the controls in the page.

How do I do this?, ive found out how to create a pdf, but not how to load one from server.

I have an application which is used by others on different server without problems. The app was programmed by a programmer who is not available now. It was developed on .net 2.0. The windows 2003 is a new server, asp.net is enabled. from iis, I can configure it to use asp.net 2.0....,
but, when I load the site, it always show the 404. even after I change the default.aspx to a blank page, it still shows 404. however, if I put a default.htm in the folder, and it can be loaded without problems.
what can cause this? how to fix it? if I installed a vs2005 express on the server, will it fix the problem?
it seems the asp.net 2.0 dll is not recognized on server. never had this problem before.

I am working solo on an Asp.net/C# project created by someone in the past. I created two new web forms, and then built the prjocect and did the deploy using a TFS team build project. For some strange reason, my Aspx file is not getting copied to the destination DEV server. It does get copied to a temp folder on that server, but in the end, the team build is failing and not copying over the new Aspx file.
So until I figure out how to fix the team build script, is their a way to just copy the Aspx file out to the desired server location? That as well as copying out a dll which is associated with the build file?

Any tips on where to start looking/investigate Re how to code pages to only load/render images when that part of the page is visible ?

Is it possible to read an .aspx-file from the filesystem, probably translate it into the Page-object and then render it into HTML? And then writing it back to the filesystem as a .html file.
The .aspx file on the filesystem is without the codebehind file. If possible provide me some example code.
I'm developing a Asp.net server control (inherited from DataBoundControl) and I have just one button inside it for now which is created in CreateChildControls override.

I am trying to use aspx pages as an email templates. There will likely be a bunch of objects on the page which will be used as replacements in the html. Because it's an aspx page I'll be able to use databinding, repeaters, etc. At run time, I want to be able to instantiate the aspx page from its path, pass in a bunch of properties, and then get the rendered result of the page and email it. This seems pretty straightforward from a asp.net website (maybe using BuildManager or Server.Execute.) However, I want to be able to use the same templates via a console application by just loading up a page object from its filepath. Is this possible?
