Yes we can, the best example you can find is AJAX network call back approach. Where a web service exposed in the server side is consumed by the proxy client in the client system using javascript.

Friend Ajax is the best example for you which does the same thing.... In fact this is leveraged most in .NET 3.0

Hi Friends
I have to set up a server which stores audio and video files. This has to be done
using ASP.NET and SQL Server.That is, whenever there is a new audio or video file I should be able to browse and store it in the database.
Any idea how to achieve this.
Thank you
|

Can you please clarify your problem a little more?

I have to store audio files in SQL Server. WebPage users should be able to download those files when clicking on it. Iam using ASP.NET application. How can I do it.
|
|

|

A powerful server, hell lot of bandwidth and a seriously large storage disk. Coming down to the actual implementation, you can store any binary type in the SQL Server image datatype or the VarBinary(MAX) datatype (SQL Server 2005). You can design your ASP.NET application to handle your files like any other file stored in the database, unless you want to stream your content.

Hi
Have you any idea that how to print a page in a button click without showing Print dialog for a web page.
If we use javascript window.print(), it prompts Print dialog. The requirement is direct printing on client side without prompting print dialog in a single button click on a web page. I am using ASP.NET with C#.
Solution require as soon as possible.
Thanks in advance.

I don't thik this is possible, as we don't have any control on client machine, any how if this is possible then it seems a big security issue.

To do that you need direct access to the client computer, and for that you need to use an ActiveX component that runs in the browser. This of course rules out all non-Windows operating systems.

Please write the ActiveX component name and how to use it.

I don't know of any specific component that does what you want. You have to decide exactly what it is that you want, and start looking around for components that do this.

Hi,
In an asp.net1.1 application I have a datagrid which was working but now its Command events (ButtonColumn and EditCommandColumn events )are not handled any more.The only change I made is adding a header and footer usercontrols.
Please any suggestion could be helpful.
I am too late but i will never give up
|
|
|
|
|
This is an issue with VS, if you open the page in design view some time the registered events gets removed automatically, so re-register your event.

Hi,
If you mean double click the event in the properties window then I did it already but no use.I have checked the event handling code (eventname+=new...) but every thing is ok.I forgot to mention that the datagrid is in a table cell (td) and the table is in a usercontrol.
I am too late but i will never give up

Hi,
As Prakash said, this is an issue with VS. I had faced similar problem just two days back. I had just clear the aspnet_wp.exe from the task manager, rebuild the application more than one times, then it got corrected. Try once more. it will work.
Best Wishes

Why do people insist on catching errors they don't know how to handle then throw away useful information!
I would suspect that you shouldn't be getting a data type mismatch error at all, so why are you catching it here... Oh... I see because it it the button click event handler...
Why do you have database code in the presentation layer?! You'll be glad you don't work for the company I work for. It is written into out coding standards documentation that the use of data access code in a windows or web form is a sackable offence.
First, comment out the catch block. Find out exacly what is causing the exception and fix it.

This was surely not production code ? The giveaway is that the button is called Button1....
