hi,
I have Problem while working with Update Panel and UpdateProgress
I have used dropDownLists in the Update Panel
But I am getting this error while running the application

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

If anybody have solution for this , Plz Help me
Thanks.

Help with SQL using .net 3.5 and visual basic

Not sure if this belongs in the VB section or here, but here goes.

I'm just learning the .net language and I'm really enjoying it, but I've hit a roadblock.

I can't seem to get the SQL part of it going. I can't figure out how to programmatically attach to a SQL database and insert, delete or edit rows. I can make the tools do it, but not just within the code.

For now, here is what I'm trying to do. (eventually I'll build on this.)

Right now, I have a page built with nothing more than three textboxes and a button. I have a database called 'testdb' with four columns: first, second, third and control. Control is marked as a primary key and identity field. First is of type 'int', second is of type nchar(10), third is of type datetime and control is of type int.

All I want, is that when you press the button, a new record gets created in the database where each of the values you entered in the textboxes gets put in the database.

Seems simple enough, but I can't quite figure it out.

Thanks.

Sigh.

I'm still not able to make it work.

I've added the code that is listed in the web.config and the button, but where do I put the stored procedure stuff?

I'm also thinking that it somehow has to link up to my database somehow, but I don't see where I enter the information as to what my database name is. (I'm assuming that I need to create columns with the names 'name' and 'city'.

Sorry to be so obtuse here, but I'm really new to this stuff.

Thanks.

Can anyone help me with this? It's just driving me crazy. I've been working on it for two weeks now and I can't figure out how to do it and I can't find anyone I know who knows how to make it work. I've been working with the code listed on the webpage and other websites I've found and I can't get anything to run.

I even downloaded the code listed on the page, but when I run it I get :

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.

Hi,

What would be the best way to have live videos on an ASP.NET website? I have read that flash servers can do this. But what would be the alternatives?

On of our client websites are in DNN and they inquired with us if this is possible.

Hi, I found the WebVideo.dll from this project : http://www.c-sharpcorner.com/UploadFile/scottlysle/CsharpWebVideo04212007133218PM/CsharpWebVideo.aspx[^]
Are we talking about the same dll? Because I used this dll to add components to the toolbox but all I got was a component named WVC which is based on Windows Media Player activex. But I need to use a vlc player based component in my web application, so can you tell me what I can do.
thanks a lot..

Hi,
I have a website in which users save thier reports but the problem is this after filling up all the information when user clicks the submit button lots of validation process takes place. So in slow speed internet connections they often press submit twice and beacuse of that information gets duplicated.
I want to stop this duplicate entry. For this i tried to disable submit button when user clicks the button and enable it later on after all the processing is done but this doesnt work.

Help me how to do it.

simple fix for this is to use js to disable the button once it is clicked.

Devesh,
There are multiple option to do it.
You can use JAVA Script to Enable and disabled the button as Yusuf suggested.
You can show a layer (Div)with proper message on you page which will prevent user to some more click on the page.
