What is difference between Viewstate and Querystring?

Re: Viewstate

Abhijit Jana23-Sep-09 21:58

Querystring is derved from the URL

Example: http://test.com/User.aspx?useid=123

And you need to retreive it on User.aspx as,
string UserID=Request.QueryString["userid"].ToString();

View State is one of the most important and useful client side state management mechanism. It can store the page value at the time of post back (Sending and Receiving information from Server) of your page. ASP.NET pages provide the ViewState property as a built-in structure for automatically storing values between multiple requests for the same page.

Example:

If you want to add one variable in View State,

ViewState["Var"]=Count;

For Retrieving information from View State

string Test=ViewState["TestVal"];

SELECT MAX(ID) AS LastID FROM mytable

This has nothing to do with ASP.NET, and it shows you have no idea at all what you're doing. You should start with a basic book.

Hi All,

I would like to perform some validation on an entry into a text box in the TextChanged event without causing the entire page to refresh.

In a Email-ID TextBox m checking whether that mailid is duplicate or not.
I want to prevent user by entering duplicate mail-id.

I used Update Panel, still it get refresh.

any solution ??

why text change event ? Its means you are doing post back on every changed of textbox char. Do it on Submit button click. And Place the control inside upodate panel.

Do you have multiple update panel in the page ?

You can use the Generic Handler for this purpose. Just put ur whole logic to identify the duplicate email then call this handler via xmlhttprequest.

var xmlhttp;

function InitXmlHttpRequest() {

    xmlhttp = null;
    if (window.XMLHttpRequest) {
        // code for all new browsers
        xmlhttp = new XMLHttpRequest();
    }
    else if (window.ActiveXObject) {
        // code for IE5 and IE6
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }
}


function CheckDuplicateEmail(url) {

    InitXmlHttpRequest();

    var handleStateChanged = function() {
        if (xmlhttp.readyState == 4) {  // 4 = "loaded"
            if (xmlhttp.status == 200) { // 200 = OK
                try {
                    alert("message from server : " + xmlhttp.responseText);
                }
                catch (e) {
                }
            }
            else {
                //alert("Problem retrieving XML data");
            }
        }
    };

    if (xmlhttp != null) {
        xmlhttp.onreadystatechange = handleStateChanged;
        xmlhttp.open("GET", url, true);
        xmlhttp.send(null);
    }
    else {
        //alert("Your browser does not support XMLHTTP.");
    }
}

now you can call this js method (CheckDuplicateEmail) on any event like textchangesd, lostfocus or keyup. Here the url is the Url of the Generic Handler u have created in previous step. The ResponseText will give you the data that u have returned from Generic Handler.

I hope it gonna help u.
