Hi Guys,
I have a problem with my Search page. When I am searching for some value it will display all the records, but then, when I clicked one of the records on the gridview, it will redirect to the other page.
The problem is that, when clicking the back button of the internet browser it will go back to the first page where it came from. But the problem is that the gridview is clear, which is it shouldn't be.
Is there a way to preserve the content of the first page, so that when we click on the 'Back' or 'Previous' button the result should be remained there.
How should I do it?

No.
The browser is free to cache the page itself in some form, but if that content has been modified via script the cached copy may not reflect this - if you want to preserve that state, you'll have to use some method that allows your script to run again and re-apply the changes, or to inform the browser that it should cache a different page (via redirects, iframe navigation, etc).
Of course, the browser may not cache the page at all, in which case your server app must be able to return the expected page in response to whatever request is sent - again, if you're doing partial page updates via XmlHttp or equiv, this may not happen unless you go out of your way to retain the apparent client state server-side (or use cookies, etc. to maintain it client-side in a server-accessible way).
BTW: i suspect you're using ASP.NET-specific stuff here, you might want to try that forum first.

Hi,
I have a products page, this page is used to display any single product which was selected. If I save a products meta title, meta keywords and meta description in my products table and write it the page, how does this affect search engines to pick up the products? Any advice that I need to follow?
Thanks
Brendan

Adding the product title and description in meta is nice.. but if you wanna your site to be visibled in Search Engines, you should also consider using Friendly URL in your page... The most of search engines like the URL like this (http://urcom.com/product/fruits/apple ) instead of ("http://urcom.com/prod.aspx?id=11xx39387x&loc=NY&ctr=387")
Actually, there are a lot of things to consider if you wanna make your site visible... You may read the article related to SEO..

Thanks and yes I know that search engines like URLs. But my question is how do search engines search values of a product whose details is only displayed when clicked on? Meaning the values are still in the database. Please make this a bit clearer for me.

I will share you the way I understand about Google SEO things.. Actually, the meta tag doesn't matter for Google since a lot of SEO experts used to trick the Search engine by adding a lot of meta tags in their pages..
1. Google calculates the Pagerank of your page or your site.
2. then, your URL should be Search-engine friendly.. If you wanna know about URL rewritting in ASP.NET, you can read this article URL Rewriting in ASP.NET
3. then, you can add your product information in the meta description and keyword
<meta name="keywords" content="meta data, meta-data, keywords..">
<meta name="description" content="meta data, meta-data, keywords..">
4. Google will read the content of your page (not just meta tags).. so, you should include h1, h2 or h3 in your page too..
5. You should generate the Google Sitemap for your website and submit your site to Google and other search enginee..

Hey,
Do you know how to get an URL like that? I know it's called URL rewriritng but I do not know how to do it.

Hi,
What would be the best way of making a transaction from a aspx webpage to the SQL database for example,
where a customer orders a product, hits the order button and then this transaction goes through to the database where it automatically updates the records. Any ideas?
cheers

As you are asking about the best way, I would like to suggest you to use the different layers for making a transaction.. Let's say you are working on the "Product Order" page. So, you should create the Order class in Entity layer. If the user hits the order button after filling the required data on your page, you should fill those data to the "Order" object. then, Call the web service proxy call to invoke the business logic web service.. then, Call the DAL and pass the data from "Order" object to the stored procedure..
So, the structure of project will be like that ~
YourProject.Entities (Class Library)
- Order (Class)
- Orders (Class)
- [WebProxies]
-- OrderProxy (Webservice proxy generated by using wsdl)
YourProject.Web (Web Project)
- ProductOrder.aspx ( Webpage)
YourProject.BO (Web Service)
- OrderBO
YourProject.DAL (Class Library)
- OrderDAL
SQL Server
- OrderStoredProcedure
This is the way that we used in our live project... it works pretty well.. but I think that it might be a lit bit complicated for beginner..

We can use normal insert sql statement. In the POSTBACK you have to write the script for inserting database. Read all the objects value you enter and using insert into statement insert all in the database.

Did you consider having that news content in a DIV and periodically update it using XmlHttp?

He wants to update it *daily*, you want to use AJAX so people who leave the site open for days at a time see updates ?

Missed that word. I was actually reading news from NDTV website where it shows a little marquee, which perhaps inspired me.

The obvious thing to do here is to have a database which contains the daily news, a page which allows you to enter news for today, and a main page that pulls the most recent news story and shows it.

I need to get a session variable's value (filename) into the aspx page,so that I can load a session based filename into Media Player Embedded.The Jscript works with a static filename at present.
// FROM THE CODE BEHIND THE ASPX PAGE
this.Session["WavName"] = Server.MapPath(@"..\captchaTmpWavs\")
+ this.Session.SessionID + ".wav";
// FROM THE ASPX PAGE
function StartMeUp()
{
MediaPlayer.Filename = "";
}
|
|
|
|
|
you can register the whole javascript function from code behind using clientscript.registerscriptblock
or you can try this
MediaPlayer.Filename = "<%=Session["WavName"]%>";
-----
|
|
|
|
|
Tried this solution and get 'Unknown Exception' when
I press My Run button.
MediaPlayer.Filename = "<%=Session["WavName"]%>";
|
|
|
|
|
I doubted that because I never tested that.
Do this right after you set the session:
<br />
<br />
string script = string.Format("function StartMeUp(){ MediaPlayer.Filename='{0}'; }</SCRIPT>", Session["WavName"]);<br />
<br />
ClientScript.RegisterClientScriptBlock(this.GetType(),"WavName",script,true);<br />
<br />

The client is stuck for now with framework 1.0
so I had to use the older Page.RegisterClientScriptBlock.
string script = string.Format("function StartMeUp(){
MediaPlayer.Filename='{0}'; }", Session["WavName"].ToString());
Page.RegisterClientScriptBlock("StartMeUp",script);
Compiles fine, but during Page Load I get the error "Input string was not in a correct format." I can't spot the problem.

in the view source of the HTML page, see what the ending string the above code has registered. You may have to add language='JScript" in and @ sign before Session["WavName"].ToString().
<div class="ForumSig">-----</div>

You are putting a physical file name in the session variable. That is useless in a web page, you need the virtual file name.
Do you need to keep the file name in the session for some reason? Otherwise you don't need a session variable to put the value in the page. A plain member variable in the page works just fine.
Experience is the sum of all the mistakes you have done.
