You can try and add a separate function into the datafield template, that calls the name of the wine, using the id you got from the select query, for that specific field.
EG: As the following into your
GetNameForID(wineID) //Id for the wine name you want to add here
or how about using parent/child relationship repeater or datagrid?
|
|
|
|
|
Why not join the table with the wine name in your stored procedure and add the column to you grid???
The other option is to add a template column with a label. Then use the ItemDataBound event of the grid and populate the label via code. However, I would think the first method would be much more efficient and simpler.
//inside the itemdatabound method
DataRowView dr = (DataRowView) e.Item.DataItem;
//something like this
LabelWineName = objWine(dr["WineID_FK"]).name;
Note that if the wine class is make a database call then you are really making a mistake. The join in your original proc would be much more efficient.

Thanks for this, but then what is the use of having class relations?? Or am I missing the plot her??

Yeah, you are missing the point. With an ASP.Net application all of the server side code has to run between postbacks. In other words 99% of your code is executed in < 1 second of time. How many class objects can you instantiate during that time interval? Not many. Even when I only working with only one database record I usually use a structure instead of class because it has less overhead.
I have been programming ASP.Net applications for 5 years now and have coded about 25 applications. Most of them have only a couple class files, not including our base class.

Hi! Is there a method to unregister client script block in ASP.net 2.0.
I'm using ClientScript.RegisterStartupScript to register client script which needs to be unregistered based on a condition.
Many thanks.

just use ClientScript.RegisterStartupScript(page.gettype(), "sameName", "");
problem solved.

i have created a guestbook module. it contains many guestbooks.
Each guestbook contains messages.
There is a guestbook detail page, showing guestbook details (name, start date, end date, ....) and messages (with paging of course). I found when pagesize is 400 (and there are 400 hundred message or more), then all buttons (with postback) in the guestbook detail page doesn't work.
after i click it, the page will show error "can not find server", as we usually encounter when we open a browser with no internet connection or the address we type is incorrect)

simple
-go to visual studio command prompt
-installutil -i [path of that service i.e exe]
This command will install the service in windows services
Depending on the start mode i.e Automatic,manual the service is started

I hope this will help you
-For that you need to create a batch file i.e same command copy in to notepad and save as .bat extn.
-Make sure that service path is given properly in batch file.
-In the setup project add this batch file so that it will execute first
before starting installation of your actual web project.
