Hello.
I have the following ASPX page:
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title></title>
<script src="js/jquery-1.2.6.min.js" type="text/javascript"></script>
<script src="js/jquery-ui-1.6.custom.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function() {
$("#dialog").dialog({
bgiframe: true,
autoOpen: false,
height: 300,
modal: true,
buttons: {
'Ok': function() {
$(this).dialog('close');
__doPostBack('TreeNew', '');
},
Cancel: function() {
$(this).dialog('close');
}
},
close: function() {
;
}
});
});
function ShowDialog() {
$('#dialog').dialog('open');
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="TreeNew" runat="server" Text="Nuevo" OnClientClick="ShowDialog(); return false;"/>
<asp:Label ID="Message" runat="server"></asp:Label>
<div id="dialog" title="Create new user">
<p id="validateTips">All form fields are required.</p>
<asp:RadioButtonList ID="ContentTypeList" runat="server">
<asp:ListItem Value="1">Text</asp:ListItem>
<asp:ListItem Value="2">Image</asp:ListItem>
<asp:ListItem Value="3">Audio</asp:ListItem>
<asp:ListItem Value="4">Video</asp:ListItem>
</asp:RadioButtonList>
</div>
</div>
</form>
</body>
</html>
When the user click on TreeNew button appears the modal dialog, then he/she choose an option an click Ok button to do a postback.
I need that the server side execute TreeNew_Click method: How can I do that?
If I use __doPostBack('TreeNew', '') it throws me the following error: "Object expected".
UPDATE:
I found the origin for the error: the function __doPostBack is not defined. I'm not going to delete the question because I think Chris Clark's answer is so interesting.
