As an exercise in learning I am trying to put all the code for a page in .cs and then compile it to a dll. Then I call that dll from the bin directory into an aspx page.

I can get my cs to compile but on return my page is blank. I think there might be something wrong with my .cs file--but can not see anything right off. Can any of you see where I might be off a little. (ok-well with my code) :)

using System;
using System.IO;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;

namespace myPage
{

public class myPage:Control
{
protected System.Web.UI.WebControls.TextBox txtTextBox;
protected System.Web.UI.WebControls.Label lblLabel;

public void CreateChildControls(HtmlTextWriter stringWriter)
{

// Use htmlWriter to write HTML.
string strOpenHTML;
strOpenHTML = "<html><head><title>My Page</title></head>";
strOpenHTML += "<body>Enter some text:";
this.Controls.Add( new LiteralControl( strOpenHTML ) );

// Add HTMLForm Tag
HtmlForm frmForm = new HtmlForm();
frmForm.ID = "myForm";
Controls.Add( frmForm );


// Add a TextBox
txtTextBox.ID = "myTextBox";
frmForm.Controls.Add( txtTextBox );

// Add a Button
Button btnButton = new Button();
btnButton.Text = "Click Here!";

//AddHandler btnButton.Click, AddressOf Button_Click;
btnButton.Click += new EventHandler(Button_Click);
frmForm.Controls.Add( btnButton );
btnButton.Text = "Click Here!";
frmForm.Controls.Add( btnButton );

// Add Page Break
frmForm.Controls.Add( new LiteralControl( "<p>" ) );

// Add a Label
lblLabel.ID = "myLabel";
frmForm.Controls.Add( lblLabel );

// Add Closing HTML Tags
string strCloseHTML;
strCloseHTML = "</form></body></html>";
Controls.Add( new LiteralControl( strCloseHTML ) );
}

void Button_Click( object s, EventArgs e )
{
lblLabel.Text = txtTextBox.Text;
}

}
 
Thanks for your quick response! :)

Ok I did that but I still get a blank page. Do you think I might be calling the literal controls wrong? I think I am creating the Textbox correctly at the top and calling it correctly in code.
 
You also never call that sub that creates the control. Try to make a sub routine that handles MyBase.Init and make a call to your control creating sub.
Also, wouldnt it be easier to let VS.NET do this for you? :)
 
Let me keep trying. I am trying your suggestions and I will get back to you soon. I know I am missing simple things. Thanks for your patience and help.
 
This may be obvious but did you tell your asp.net page what is and where is the file for code behind?
