Have you tried viewstates ? It's scope is only in the page. So no need to worry about server resource utilization.

sir...is there is any other alternate wat i mean with out session and viewstate..can't we achive this problem...k if we use view state or session which one is better one sir.

Viewstate can be tampered with and doesn't persist across pages. Session takes up room on the server. The Session is a concept that is not unique to ASP.NET, viewstate was created to create state within a stateless environment. They both have advantages, at different times.

thanks mr.Christian Graus sir for u r value advices..is there is any problem in memory allotments if i use viewstate for the datatable when a largeno users acees the same page

There won't be much problem. But if your datatable is much bigger, viewstate also will be huge. As Christian told, it is easy to tamper, so if you are keeping very sensitive information, go for sessions. If you need to keep the data only in this page and it's not sensitive, use viewstate. If all your users are seeing the same data, then cache your datatable for improved performance.

will u plz tell wat this sentence means?
|

You told you have many visitors seeing this page simultaneously. So ti improve performance, you can cache the datatable. But this is applicable if all the users are seeing same data and not user specific data.
Assume you have a website something like CP, and in your page you display all the latest articles. So this information will be same for all the visitors. You cache this data and when another user requests, load it from the cache.
Hope it makes sense.

Hi,
there is one way to do this.
Get query in which you get multi column result.
Then bind dataset to listbox.
Hope it will help you.

Hi,
you can write query like.
SELECT column1 + '-' + column2 AS MyColumn FROM tableName
Now after getting value in dataset. Bind dataset to listbox.
myList.DataSource = datset
myList.DataTextField = "MyColumn";<br />
myList.DataBind();<br />

Why don't you use GridView or something?
|
|
|
|
|
AFAIK, You can't use columns inside a listbox. Try using GridView/DataGrid

- Get the length of strDemo
- Cut the string according to the lenght of strDemo from strDemo1
- compare strDemo and strDemo1 (which has been cut)

Oh. I didn't see the Christian's reply.

How can we use 2 sitemaps in an aspx page?
|
|
|
|
|
Hello,
Definitely, you may have multiple site map paths for a single website or a page. To configure multiple site maps for a single site, start with a site map in the root of your application. Next, configure the root provider as the default site-map provider in your Web.config file. Then, link to child site maps or providers by referencing them in a SiteMapNode object. Here is a good link which I have used to create one:
http://msdn2.microsoft.com/en-us/library/ms178426.aspx
Do let me know if this works for you or not.

Buy a book on ASP.NET and work through it. Buy a book on SQL and databases, and work through it. If you want the sort of features CP has, buy a book on javascript and DHTML and work through it.
