In one of the pages I have made a simple popup calendar. The problem Im having is I keep getting the error QUOTE 'window.opener.document.forms.form1.StartDate' is null or not an object Here's the code I use to open the popup calendar jscript <a href="java script:void(0);return false;" onclick="window.open('../../Popups/PopCalendar.aspx?type=StartDate','cal','width=250,height=225')"> Here's the code in the PopCalendar.aspx csharp protected void Change_Date(object sender, System.EventArgs e) { string script = "<script language=\"javas" + "cript\">\r\n"; script += "{\r\n"; script += "if(window.opener && !window.opener.closed)\r\n"; script += "{\r\n"; script += "window.opener.document.forms[\'form1\']." + control.Value + ".value = '" + calcDate.SelectedDate.ToString("MM/dd/yyyy") + "';\r\n"; script += "self.close();\r\n"; script += "}\r\n"; script += "}\r\n"; script += "</" + "script>"; ClientScript.RegisterClientScriptBlock(this.GetType(), "SetDate", script); } I tried this experiment in VB.NET and it worked fine (not in a Master Page mind you) and in C# without a Master Page it works just fine. Anyone got any ideas?

The only time I see it used is when you pass it to the PopCalendar~ It's saying it's null, so you must be passing it before it gets assigned any kind of value. I don't do ASP, so I could be wrong. Hope this helps

Not sure it's the best solution but I solved it. When a page is in a master page a lot of funny crap is appended to the name of the controls. Changing the code in Change_Date to this works:

csharp


protected void Change_Date(object sender, System.EventArgs e)
{
    string script = "<script language=\"javas" + "cript\">\r\n";
    script += "{\r\n";
    script += "if(window.opener && !window.opener.closed)\r\n";
    script += "{\r\n";
    //here we will use the generated form and control name
    //to get around being in a master page
    script += "window.opener.document.forms[\'aspnetForm\'].ctl00$center_content$" + control.Value + ".value = '" + calcDate.SelectedDate.ToString("MM/dd/yyyy") + "';\r\n";
    script += "self.close();\r\n";
    script += "}\r\n";
    script += "}\r\n";
    script += "</" + "script>";
    ClientScript.RegisterClientScriptBlock(this.GetType(), "SetDate", script);
}
