Difference between tml control | server control with examples in asp.net

asp.net controls | html control | server control with examples code
1)default = the class name by default defined in System.Web.UI.Page
2)default.aspx = it is class internally and it derived from

System.Web.UI.Page

Controls in asp.net

1) asp .net supports two types control
i)Html server control
ii)Server side control
i)Html server control:-This control we use for migration purpose.
ii)These controls are defined in System.Web.UI.HtmlControls;


2)Server side controls :- These are xml based controls
i)These controls are defined in System.Web.UI.WebControls; web page
ii) web server controls can communicate web server directly.
iii)In asp .net by default your page will be submit using post method.

Difference between Response.Redirect , Server.Transfer

asp.net | Response.Redirect |  Server.Transfer method using program code source

Asp.net supports only one form  at the server side.
Redirection page:-if we want  to navigate from one page to another
page we have to use following method.
1)Response.Redirect
2)Server.Transfer

create new form in asp.net
craete a new asp.net website from the solution explorer and add new

item for web.Form

page Load:-

Response.Redirect ();

-we can find destination file name  at the url i.e

this file displaying by the browser destination.

Server Transfer:-
this file is displaying by the web server because of this  we can not find
destination file name at the url.


using System;

public partial class Default2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Response.Write("we are in new page");
}

{

}
protected void Button2_Click(object sender, EventArgs e)
{
//Response.Redirect("default1.aspx");
Server.Transfer("default2.aspx");
}
}
1) run this program with help of two button and one text box
2) when you will click on button 1 then message will come on text box

and if you will click on the button 2 then it will give msg on page load .
i.e "we are in new page ".
when click on button one then

TextBox1.Text = "asp.net event programming"; this will work

means "asp.net event programming"; this msg will appear in the text

box 1.
3) if  you will execeute both then problem comes in

//Response.Redirect("default1.aspx"); this line.

we wrote there on page load msg will come on screen it means it
transfer same msg using Server transfer. asfter click on button 2 it will
give msg what we have seen on page load.

well something for work?
find out meaning of this line.....

  </connectionStrings>
Add name and  again back to code behind on page load and check this line

    SqlConnection con = new SqlConnection();
In the place of stud that I sactually my database name write add name that is
