for example you show all the topics realted to 14014 and when i wanna to reply

http://forum.yetanotherforum.net/yaf_postmessage.aspx ?t=14014&f=37

i want like this in my page ?

<YAF:LastPosts ID="LastPosts1" runat="server" Visible="false" />
<div id="DivSmartScroller">
	<YAF:SmartScroller ID="SmartScroller1" runat="server" />
</div>

So you want to look at the LastPosts control, or create a custom version of one for your needs.

Good luck,

Dave

the lastpost control after dragging it,it didnt show any thing except the scrollbar,

plz can you show me exacty how to do this ?

Regarding your issue - if you are trying to access posts through the querystring, and getting object errors, you most likely don't have all your references in place. You will need the source code to YAF (downloadable via the [url="http://yafnet.codeplex.com"]CodePlex repository[/url]). I would start by going through the code in posts.ascx, posts.ascx.cs, and so on. That file is what renders the post listing for a thread. Unless you are trying to display YAF code in custom pages, why can't you just use the existing YAF pages and send the URL to them as YAF does?
