Error: 'opener.document' is null or not an objectQuestion:

The above error occurs when I click a hyperlink on a child window. How can I solve the problem?

<input onclick="Javascript:window.showModalDialog('Customers.aspx', '', 'dialogWidth:300px;dialogHieight:300px;status=no;scrollbars=no;');" return false" type="button" value="Pick" />

<a href="#" onclick="opener.document.forms[0].txtCustId.Text='<%# Eval("Id") %>';opener.document.forms[0].txtName.Text='<%# Eval("Name") %>'; window.close(); return false"> <%# Eval("Id")%></a>

thanks

window.opener does not work when used with showModalDialog I'm afraid, the only thing available is the returnValue that can be set on the child page.
You could pass back some comma seperated values back or something like that :

Otherwise you would have to go back to using window.open

showModalDialog is not a window the same way window.open is. So, yeah, window.opener is null.

Check out this page:

Use 'dialogArguments' to move do updates and such.

Code for parent page

<script type="text/javascript"> 
function openModalWindow(url, height, width) { 
    var features = 'dialogWidth:' + width + ';dialogHeight:' + height + ';status:no;scrollbars:no;' 
    var rVal = window.showModalDialog(url, "", features); 
    if (rVal != null)
    {
        document.getElementById("mycontrolId1").Value = rVal[0];
        document.getElementById("mycontrolId2").Value = rVal[1];
    }
} 
</script>

Open in new window

code for child page called from a save button or close button

<script type="text/javascript">
function closeWindow()
{
    var arrReturnVals = new Array(document.getElementById(ctrl1).Value, document.getElelmentById(ctrl2).Value);
    window.returnValue = arrReturnVals;
    window.close();
}
</script>

Open in new window
