Here i will explain the binding of a treeview from the Database.This can be a tricky task since we may have to build a parent-child relationship here.So first thing you would need is a table in the database where we actually have the parent-child relationship.
An Example
Table Name: Category
CategoryId  INT
CategoryName  Varchar(50)
ParentCategoryId INT
NodeLevel  INT

1
Root

Eg:

Response.Redirect(”~/Default.aspx”,false);
This error also happens when Server.Transfer method is called.Just use Server.Execute …

Also,before the method “Hello World”,a [WebMethod] attributed has been specified.This basically tells the compiller …
