Terry,
It worked for the test page only. On my real pages it didn't because the controls are not at the same position. You could see that the line and column are "almost" matching (if you put the green mask) but they are not. To test that just add other uploader control(s) to the test page at another position.
For example, just add this code after the
</ajaxtoolkit:tabcontainer>
<br />
<br />
<table cellpadding="0" cellspacing="0" style="height: 100%">
<tr>
<td align="left" valign="top">
</td>
<td align="right" valign="top">
<table cellpadding="0" cellspacing="0">
<tr>
<td align="right">
<cutewebui:uploadattachments runat="server" id="Uploader3" multiplefilesupload="true"
inserttext="Upload" uploadtype="Flash">
<ValidateOption MaxSizeKB="10240" />
</cutewebui:uploadattachments>
</td>
</tr>
<tr>
<td style="vertical-align: middle; text-align: right; height: 28px;">
some text
</td>
</tr>
</table>
</td>
</tr>
</table>
Can you also please test with other cenarios/positions?
Thanks a lot.
