Handler ? What do you meant by that. It's control object which raised that event. If you know control type, you can cast this to your control type.

Have you considered buying a book ?

The sender is the object that raised the event. The eventargs is a base class, events that send meaningful data do so via a class derived from eventargs, such as KeyPressEventArgs.

Damn. Let me try to explain it again. The EventArgs class is a base class. It contains no useful information. It's utility is that events that DO recieve meaningful information ( such as a keypress ) can use the same framework to send event information, because the classes which contain that information, are derived from the EventArgs class.

As I told in my previous post, EvertArgs is base class for events. Why this comes with each event handlers ? If .NET team needs to add some additional functionality for events, they can do this without making changes to all the event handlers which are already in use.

Use Window.Parent with form name and your control name to get that controls object from popup window.

The code you wrote has some spaces in it. Are you getting an error or just not getting the values? Did you debug to check if the Text properties hold some values? where are you placing the code to retrieve the querystring elements? Is it on a postback or on first post?

Try this code

Response.Redirect("WebForm2.aspx? name="+Server.UrlEncode(this.txtname.Text)+" & city="+Server.UrlEncodethis.txtcity.Text));<br />
<br />
<br />
this.txtname1.Text=Server.UrlDecodeRequest.QueryString["name"].ToString());<br />
this.txtcity1.Text=Server.UrlDecode(Request.QueryString["city"].ToString());<br />

Best Regard

But without the spaces.

You don't decode the values from Request.QueryString. that is done automatically. Also, you don't need to use ToString to convert a string from a string to a string.

this.txtname1.Text = Request.QueryString["name"];
this.txtcity1.Text = Request.QueryString["city"];

Dear pathan,

Response.Redirect("querystring1.aspx? name="+Server.UrlEncode(this.txtname.Text)+" & city="+Server.UrlEncode(this.txtcity.Text));

this.txtname1.Text=Server.UrlDecode(Request.QueryString["name"].ToString());
this.txtcity1.Text=Server.UrlDecode(Request.QueryString["city"].ToString());

I tryed the code,but following error is comming."Object reference not set to an instance of an object".

That's because there is no item in the Reqeust.QueryString collection with the key "city". Due to your extra spaces the key is " city".

You have spaces in the url, which should not be there. Also, you need to url-encode the values to be able to handle more than the most simple values.

Response.Redirect("WebForm2.aspx?name=" + Server.UrlEncode(this.txtname.Text) + "&city=" + Server.UrlEncode(this.txtcity.Text));
