Re: Postback event fails in asp.net 2.0(Page cannot find server/DNS Error)

13-Jul-07 10:39

I have ported my Visual Studio2003/asp.net 1.1 web application on to Visual Studio 2005/asp.net2.0 platform. One page of this web application behaves strangely. On the home page of the application there is a header control and footer control. These user controls have links which allows users to go to various pages upon clicking. All except one link somehow behaves differently. This link however upon clicking opens up correct page but on clicking any button or even doing selected item change on drop down box on the page displays error like “The page can not be displayed” and “cannot find Server or DNS Error”. The server on which this web application is deployed is Windows 2003 sever with IIS 6.0 and asp.net 2.0 and .Net Framework 2.0. I even created a brand new page with just a button control and a text label. But clicking on this button I get the same error message as above. It seems that Post back event is failing. The Header Control implements IPostBackEventHandler and IPostBackDataHandler interface defined in Microsoft Library. This application works fine in with Visual Studio2003/asp.net 1.1.
Can any one please shed light how to solve this problem?
I would like to thank you in advance for your help.

Have you checked through all of your connection points?

Is the web server correct too? I am wondering if it is a network matter...

Yes the webserver is on network. But same was the case earlier too during deployment in Framework1.1 enviornment.

Your only option to do that on a simple html page is to use an mailto: url in a form. This will use the mail program on the visitors computer, so it will of couse only work from a computer that actually has a mail program installed with a working email account.

If you don't want to go down the line of developing your own server-sode code for this, and your website is hosted by an independednt ISP, ask them - most offer a cgi script you can utilise to do this.

u can do validation using Javascript.
function IsNumeric(sText)
{
var ValidChars = "0123456789.";
var IsNumber=true;
var Char;

for (i = 0; i < sText.length && IsNumber == true; i++)
{
Char = sText.charAt(i);
if (ValidChars.indexOf(Char) == -1)
{
IsNumber = false;
}
}
return IsNumber;

}

This Javascript function

function chkQty(qty) {
var regex = /^\d+$/;
if ( !regex.test(qty) ) {
alert('Please enter a number larger than 0');
return false;
}
return true;
}

will return true only for +ve whole numbers passed to it, so you can use it to check the textbox entry on submiting the form, or even on the onblur event of the box itself

Use RegularExpressionValidator then open properties and simplye write down \d{0,9} in validation expression property. It will validate on client side.
