Did you ever get a response or find out an answer to this? I'm actually trying to do the exact same thing and am having difficulty finding a solution anywhere.

See this :
Simple Chat Application in ASP.NET[^]
Actually the concept is each client will update the server using AJAX, so that once server is updated, the other person gets notified.

you should buy a basic ASP.NET book and read it, so you have an understanding of the framework you are using.
The answer to your specific question is, each postback causes a new instance of the page class to be created, and it exists only for that postback. That is why things like viewstate and the session exist ( again, look into that book )

Also, once you deploy your app, it won't be able to see above the root of your website. Again, refer to that book.

Respected,
Can I Insert GridView multiple Records on one click.
Thanks
|
|
|
|
|
Yes.
1. To insert records in gridview: Update its datasource and rebind.
2. To insert gridview records in database: get the records to insert and use ADO.Net to perform the insert.

Convert the Gridview to string..
Dim stringWrite As New System.IO.StringWriter
Dim htmlWrite As New HtmlTextWriter(stringWrite)
GridView.RenderControl(htmlWrite)
Dim Body as string=htmlWrite.tostring

Hai friend's
i created one web appliction with visual studio2005 , while i ran that page with internet Explorer it show's the same design which i created , then i tried the application with some other browsers like mozilla , opera and google chrome, it not showed the correct design what i did , i mean the picture went one side and the table went one side , i am just a beginner so help me out how to create the web application that should suitable for all the browsers....
thank you...

The major and most important thing that you need to look into CSS and javaScript for supporting the multiple browser. Never Drag and Drop controls in ASP.NET pages at Visual Studio IDE Design view. Always use code view for proper design with Table and Div. Please go through the link that other person suggested.

Use W3C standard CSS to control the look and feel of the page.
Make everything fluid where possible. Use percentages for font sizes and widths/heights of elements. 'Fixing' to many elements with fixed values can cause a lot of problems.
Remember NOT all browsers will behave the same for everything - I'm afraid SOME elements won't. For the ones that don't you'll have to do a little research.
For example to change the colour of a horizontal rule correctly you would have <hr style="color:#ff0000"/> - works fine in IE browsers but not in FF - the fix is <hr style="color:#ff0000;border:0px;height:2px;background-color:#ff0000"/> - note we have to add the border, height and background-color attributes - still correct and works in all browsers.
All this comes with a little a research and experience. I would just start off by researching each problem element as it comes along specifically and as you need. Not the whole lot.
