TreeView postback to calling page?

[Harold]

I have page A with form field and a button and when button is clicked it
opens page B in another window. Page B has a treeview control and that is
all. When something is selected I want the page B item to pouplate a form
field on page A. Can this be done and how?

This is what I did. On page B with the treeview I added a HTML Button, and 2
hidden asp.net fields to the page.
<input id="btnClose" type="button" value="Close" onclick="postdata();" />

<input id="hOrgText" type="hidden" runat=server />

<input id="hOrgVal" type="hidden" runat=server />



Sub TreeView_Select(ByVal sender As Object, ByVal e As EventArgs)

'Set the hidden forms fields so javascript can send the values back to
calling page.

hOrgText.Value = TreeView1.SelectedNode.Text

hOrgVal.Value = TreeView1.SelectedNode.Value

End Sub

<script type="text/javascript">

function postdata(){

top.opener.document.forms[0].elements["txtOrg"].value =
document.forms[0].item("hOrgText").value;

top.opener.document.forms[0].elements["hidOrg"].value =
document.forms[0].item("hOrgVal").value;

window.close();


}

</script>

Now I can post the variables back to the calling page without reloading it.

I tried this which didn't work for me. Someone can tell me why.
top.opener.document.forms[0].elements["hidOrg"].value = <%="somevalue" %>;
