I want to know that how to open web page in different window and passed a value from javascript to c# on page load

ASP.NET

<JavaScript>
function open_win() 
{
var s=document.getElementById("txtQty");
window.open("../Stock/IPurchaseDetail.aspx","_blank","toolbar=yes, location=yes, directories=no, status=no, menubar=yes, scrollbars=yes, resizable=no, copyhistory=yes, width=400, height=400");
}

</javascript>


<asp:CheckBox runat="server" ID="chkGenerateSerialNumber" AutoPostBack="true" CausesValidation="false"
        OnCheckedChanged="chkGenerateSerialNumber_CheckedChanged" />

C#

protected void chkGenerateSerialNumber_CheckedChanged(object sender, EventArgs e)
        {

            if (chkGenerateSerialNumber.Checked == true)
            {
                Session["NoOfRows"] = txtQty.Value;


                System.Text.StringBuilder sb = new System.Text.StringBuilder();
                sb.Append(@"<script language='javascript'>");
                sb.Append(@"open_win();");
                sb.Append(@"</script>");
                ScriptManager.RegisterStartupScript(this, this.GetType(), "javascript",   sb.ToString(), true);// it does  work but in open_win() method window.open("../Stock/IPurchaseDetail.aspx","_blank","toolbar=yes, location=yes, directories=no, status=no, menubar=yes, scrollbars=yes, resizable=no, copyhistory=yes, width=400, height=400"); does not get call
}
}

Now I have got Session["NoOfRows"] = txtQty.Value; but another page does not call.

C#

protected void Page_Load(object sender, EventArgs e)
      {
          if (!IsPostBack)
          {
              NoOfRows Convert.ToInt32((string)HttpContext.Current.Session["NoOfRows"]);

          }

      }

Hello,

There are at-least two ways to do that.

Similar to your code except that the desired parameters are passed as a Query String. S your code becomes something like one shown below.

JavaScript

function open_win() {
    var s = document.getElementById("txtQty");
    var url = "../Stock/IPurchaseDetail.aspx?txtQty=" + encodeURIComponent(s.value);
    window.open(url, "_blank","toolbar=yes, location=yes, directories=no, status=no, menubar=yes, scrollbars=yes, resizable=no, copyhistory=yes, width=400, height=400");
}

This method is very much similar to above, the only difference is that you open a named window with blank url and POST the existing form to that window. Following code snippet shows how this can be done.

JavaScript

function open_win() {
    var hWin = window.open("", "hWinPurchase","toolbar=yes, location=yes, directories=no, status=no, menubar=yes, scrollbars=yes, resizable=no, copyhistory=yes, width=400, height=400");
    var frm = document.getElementById('YOUR_FORM_NAME');
    frm.target = "hWinPurchase";
    frm.submit();
}

Add target attribute to form tag thats it, you are done.
Now whenever button is clicked, aspx will open in new window.
Paste the following code in your .ASPX page

ASP.NET

<form id="form1" runat="server" target="_blank">

<!-- Add your buttons herere -->

</form>
