PopUp Window onload

I want to open a small pop up window when the page first loads.  

I tried doing it as javascript on load on the html page, but the page does postback as I have radio buttons on it, and I don't want the pop up to load everytime the page loads - just the first load.

Does anyone have any ideas how I can do this?

Can I call a client side function from code behind pages?

yuo should put this in your code behind
this is in C#, but is should be pretty easy to change.

I delcare a string, append all my javascript commands to the string and then response.write it out.


private void Page_Load(object sender, System.EventArgs e)
            {

                  if(!IsPostBack)
                  {      
                        String s = null;
                        
                        // Script Header
                        s += "<Script>";
                        //Varibale Declaration
                        //Varibale Declaration
                        s += "var hwnd = window.open('about:blank','Advisor','toolbar=no scrollbars = no location=no width=400 height=200');";
                        s += "hwnd.moveTo(screen.width/4, screen.height/4);";
                        //Property Settings
                        s += "hwnd.document.bgColor = 'lightyellow';";
                        s += "hwnd.document.body.innerHTML = '<b><br> Processing... <br><br><center> Please Wait </center></b>';";
                        //End Function
                        s += "</Script>";
                        //Execute Function
                        Response.Write(s);
                  }
            }

The key in the code is that in the On_PageLoad function you need

if IsPostback = false then


or

If !IsPostback then

              Dim ParentLoadScript As String
               Dim strURL As String

                If not page.IsPostBack Then
                    strURL = "POREP01.aspx"
                    ParentLoadScript = "<script language=javascript>"
                    ParentLoadScript &= "window.open('" + strURL + "');"
                    ParentLoadScript &= "</" & "script>"
                End If

                If Not IsClientScriptBlockRegistered("ParentLoad") Then
                    RegisterClientScriptBlock("ParentLoad", ParentLoadScript)
                End If


The above should work..Just replace the "POREP01.aspx" with the name of your pop up page..
Regards,
Priya
