Make the search and edit pages both controls and navigate by changing which one is visible. Viewstate will do the rest for you.

Iam new to ajax ..pls can any one send the code or link
how to use ajax dropdown ..

If the documentation and online samples are not enough for you, then ASP.NET AJAX in Action is a great book. Of course, none of this is going to teach you anything about AJAX, just how to use a framework that does AJAX for you, but I expect that's all you want.

Dear,
I using ASP.NET with C#, when i get records from SQL Server I don't use GridView, I use only table, so how can i use size paging?

Your most logical way is to write a pager control and then to ask your SQL database for only the records you want to view, and the number of pages.

why ? Grid view is the best option to display records from database and also for paging.
Socheat.Net wrote: use only table
you have to write code for it. you can write a class where you can set a property of page size for paging, generate table on runtime based on the page size . add navigation image on table footer for navigation.
Hope this can help you.
cheers,
Abhijit

A poll is just a group of questions, which if you have users that log in, probably tracks each answer so it can work out if you answered before, otherwise, could just track totals. Which bit are you stuck on ? Is this your first time usng a database ?

I am able to make a website in File System but when i try to make website in HTTP, I got an error message as below...
Configuring web site "http://localhost/Mywebsite' to ASP.NET 2.0 failed. You may need to manually configure this site for ASP.NET 2.0 order for your site to run correctly.
How i can solve this problem...
Would I have to setting for IIS server. If yes then give me steps for that.

|

If your running this under IIS, not the built in web server that ships with VS 2005++, you would need to install the 2.0++ framework that create a virtual directory under IIS that points to the directory containing your files.

Hello,
I have a site which has auctions (antiques). My products page takes three query parameters. Two of them ranges from ~1-10 and one from 1-40 and increasing (the auction id). Most users will only view the current auction so this one I would like to cache. Auctions which recently was active and auctions that are coming up will be visited a bit as well, but not nearly as much as the active one. Older auctions won't be visited much.
Right now I am caching my datasets which I retreive from my database. I only cache the active and some of the more frequently used ones.
The products never change really, so I could use output caching, but would this be a bad choice with so many query parameters? I guess that output caching is better then to cache the datasets as you don't have to render the html every time. Should I use a very short duration so that the output caching doesn't cache so many pages, or maybe remove less-frequently viewed pages from the output cache immediatly from the code-behind? Maybe sliding expire?
Any thoughts? Thanks

When you declare an object "static", will it be shared among different users of different machines? I couldn't test it cuz I'm testing from a single machine. I put a static variable in a common code and every time I visit a page, it shows the (user-specific) static data no matter how many refresh you make. that's fine. But will the same data be shown to any other users accessing the same page? "Static" has that much of scope??.
Thanks for your reply.
|
|
|
|
|
Yes, that is what static means. You have one server, one application instance, and static variables will be shared across it.
