Solution 1

Pass the values using querystring[^]. Try this:

JavaScript

function confirm1() {
    //Get the value from form and store it in variables.
    var ID = document.getElementById('YourID').value;
    var Name = document.getElementById('YourName').value;

    if (confirm('Are u sure??')) {
        window.open('Default2.aspx?ID='+ID+'&Name='+Name, 'mywin', 'height=400px width=500px locatio=no titlebar=0');
    }
}

Retrive it in Default2.aspx page. Please see this[^].

but isn't querystring is unsave as a sharp user can read all sensitive matter.

Then do a postback and set the values in session. You can also use Properties or Cookies.

If you do not them to be shown create a class to save the values and use Session to save them. Or if you do not want to use a class save each value to a separate Session. For more info please check: Sessions[^]

Well,approach suggested above is pretty well.Further,you can pass values through query string after encryption.

C#

String temp = Encrypt (Textbox1.Text);//Text gets encrypted using any algorithm
Response.Redirect("Webform2.aspx?Value=" +temp);

To retrieve values on another end,

C#

if(Request.QueryString["Value"] != null)
{
txtBox1.Text = Decrypt(Request.QueryString["Value"].ToString());
}

You can refer to below link for Encryption decryption

Encrypt and Decrypt Data with C#[^]

Below link will explain alot about passing values.
