Hi,
Please check two things:
1. Most of the time it has to do with some unclosed element in in your page. For example:
Code: HTML/ASPX
<form runat="server" id="form1">
<table>
<tr>
<td>
<eo:MultiPage>
<eo:PageView runat="server" id="PageView1">Page View 1</eo:PageView>
<eo:PageView runat="server" id="PageView2">Page View 2</eo:PageView>
</eo:MultiPage>
</form>
In the above example the td is not closed, such problems in the page content can cause all kind of strange problems on the MultiPage control. Likewise, if you have some unclosed elements inside the PageView, that can cause problems as well.
2. Sometimes your stylesheet could interfere with our controls. Try to temporarily comment them out and see if that fixes the problem;
Try to start with a empty page and several empty page views, then you can gradually add contents in and you should be able to find out the offending part.
Thanks
