The first step when your code is this messy, is to break it down into many smaller pieces of code, so you can work out which one has the problem.

Christian was right.
That method name is OOP ( Object Oriented Programming ).

|

I don't think OOP is the point here, he doesn't need an object, just better structured procedural code

Dear All,
I am using asp.net2.0, C#, sql2005 using Visual studio 2005
Let Me explain the scenario I have checkboxlist containg 15 field. Based on no of checked field . I created dropdownlistbox and label dynamically through loop and assign id as dropdownlist + no of iteration. Now my question is how I access these control as when I am accessing one of the control I am getting nullobjectreference error stating “Object reference not set to an instance of an object.”I created control as
Foreach(listitem)
{
//…….
Label label = new Label();
DropDownList dropdownlist = new DropDownList();
//assinging id
label.ID = "label" + i.ToString() ;
dropdownlist.ID = "dropdownlist" + i.ToString() ;
}
And I am accessing it through
cmd.Parameters.Add("@para1", SqlDbType.VarChar).Value = Page.FindControl("label1").ToString() ;
cmd.Parameters.Add("@value1", SqlDbType.VarChar).Value = Page.FindControl("dropdownlist1").ToString();
and my second question is how do i access selected value in dropdownlist1(dynamically created control)
Please guide me
Thanks

Your main problem is that if you don't add your controls bfore the page load event, viewstate will not be restored and so you don't be able to get the selected values as tehy won't be set in the code behind for you.

YES, see Submit1 is empty and you cannot convert "" into a boolean.

What is the issue? Your submit1 control has a value "" (empty). And you cannot convert that empty value into boolean.

transferring to another page using Server.Transfer conserves server resources.
Does it mean that it does not tell the browser that it transfer the user to another page.I mean -
1.it does not update the history.
2.I am sending the user to another page with some information (server.transfer(abc.aspx?id=9))
the another page - having address bar - is not showing the id .is that mean the server resource conservation
or
3.There is some other meaning of server resource conservation?

Using Server.transfer we are shifting the control of the execution to another Page on the same site. so it is not server resource conservation
