An ASP.NET web site is supposed to be deployable simply by dropping the aspx and config files on the server, which will invoke the compiler if a page has not yet been compiled etc. Is is possible to define the target Framework, i.e. 2.0 instead of 3.5, without using Visual Studio?

Definitely possible. All the files that you need to compile an application are text files. You can write everything in Notepad and use the command line compiler if you like.

Despite everything, the person most likely to be fooling you next is yourself.

Thank you, but maybe I should have phrased my question better. I already suspected this, but I wanted to know where to set the target framework in these text files.

You don't set a target framework in the files, this is a compiler option that can be set in VS.

You can use different assemblies by using the assemblyBinding element in the configuration file.

Yes, but ASP.NET files are not compiled in VS, they are compiled on the fly, so should there not be a way of telling the compiler used by the ASP.NET pipeline which framework to target?

I wouldn't think so in the case of IIS since the framework version is an IIS setting you can't expect to set it to something different for compilation. At least it doesn't seem that would work very well.

They can be, as in precompiling.

In the IIS settings you can switch the version of the .NET framework is used for a particular site, provided there are multiple install on the machine of course. I don't know if this effects to on-the-fly compilation though.

I spent the long weekend getting much, much better acquainted with Satan, i.e. data binding and the SqlDataSource. I found some wonderful jewels, like SessionParameter, but also found myself having to use SQL Profiler to, first see if my stored proc was even being called, and second, when it was being called, why it was failing. SqlDataSource raises no exceptions and exposes no error events whatsoever!

Then, my consternation, the ControlParameter. Worked wonderfully for the first page I built, using a hidden field on the form to store a select parameter for a stored procedure. With no change, the ControlParameter refused to work as an insert parameter on any further forms I built, while falling back the ever trusty Parameter and Bind() worked fine, and even the suspect SessionParameter and the even wilder QueryStringParameter all worked fine.

Another reason I'd never use it Smile | :)

TextBox and CreateChildControls()

26-Mar-08 9:49

No code!

Seriously, I found it quite nice for prototyping, when I had only so much time for layout and code, and only focussing on one view, the ascx view, made it quite feasible. The other reasons are that I'm trying to get to know all of ASP.NET better, and that includes these nasties. Rest assured my efforts also include understanding the request pipeline, IIS integration, and even the new MVC stuff.

Hi All,

I have a custom server control that derives from System.Web.UI.WebControls.TextBox. What id like to do is override the CreateChildControls method and add a hiddenfield control so I can persist some data from client side and have access to it from server side.

The problem is that this control isn't created. I have tried putting EnsureChildControls in both OnLoad and OnInit but it doesn't seem to work either way.

Any help is appreciated.

Your approach strikes me as one that should work. When you create the HiddenField, do you also add it to your Controls collection? Have you walked through in the debugger to verify that CreateChildControls is being invoked?

Hi Jesse,

I am adding the control to the Controls collection and have verified that the CreateChildControls() is being called and going to my piece of code.

I've created composite controls before where I've used the same method. Do you think its because I'm inheriting from Textbox that I am having problems?

Thanks!

It would appear that you're exactly right. When I popped open Reflector and took a look at the Render method for the TextBox, it does not make the standard call to RenderChildren. In order to have the child control render, I had to override the Render method. This worked for me:

  public class MyControl : TextBox
  {
    protected override void CreateChildControls()
    {
      this.Controls.Add(new HiddenField(){ ID = "MyHidden", Value = "TEST TEST TEST" });
      base.CreateChildControls();
    }
 
    protected override void Render(HtmlTextWriter writer)
    {
      this.RenderChildren(writer);
      base.Render(writer);
    }
  }

The above will render the Hidden field before the TextBox itself, if that matters to you. You can change the behavior by delegating to the base Render first, then calling RenderChildren.

Hope that helps. Smile | :)
