asp.net - Link to a New .aspx Page from Selected Database Entry by User -

-

i working on website using c# in asp.net , have page contains grid-view displays contents of 1 of tables in database. fields generic name, description, rating, ect. question how make when 1 of entries clicked, links new .aspx page has information displayed in nice format? example of talking can found @ http://www.imdb.com/chart/top?ref_=nv_ch_250_4.

from research have found little in way of answer, due inability ask question correctly. assume not suppose physically create new page every new entry, because crazy if have lots of database entries coming in. should there 1 page created auto-populates required fields based on specific values passed database entry selected, or when user inserts new entry database should create new .aspx page? question has had me stuck quite time, appreciate direction can provide!

create simple hyperlink rows of grid, url of hyperlink should contain reference item id or name. when link clicked passing id second page in querystring. in second page read id(request.querystring) , display details accordingly. > making hyperlink : 1 way it. add itemtemplate column in grid.

          <columns>              <asp:templatefield >                  <itemtemplate>                        <a href="products.aspx?id=<%# eval("id") %>"> view details </a>                  </itemtemplate>              </asp:templatefield>           </columns>

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
