<p>i have a page with ajaxtoolkit tabpanel control and i have a label inside this tabpanel with a form view to show error message if something happen but the text of label doesn't appear in this tabpanel while it appears in other tabpanels</p>

<pre><code> &lt;ajaxToolkit:TabPanel ID="UsersTab" runat="server" HeaderText="Users Control"&gt;
                        &lt;ContentTemplate&gt;
                            &lt;asp:UpdatePanel ID="UserPanel" runat="server"&gt;
                                &lt;ContentTemplate&gt;
                                    &lt;table border="0" cellpadding="0" cellspacing="0" align="center" width="98%"&gt;
                                        &lt;tr&gt;
                                            &lt;td class="hdr1"&gt;
                                                Add Users 
                                                &lt;asp:Label ID="LblMsgUser" runat="server"&gt;&lt;/asp:Label&gt;
                                                &lt;hr /&gt;
                                            &lt;/td&gt;
                                        &lt;/tr&gt;
                                        &lt;tr&gt;
                                            &lt;td valign="top"&gt;
                                                &lt;asp:FormView ID="UserView" runat="server" DataKeyNames="UserID" DataSourceID="ORANEWUSERDS"
                                                    DefaultMode="Insert" OnItemInserted="UserView_ItemInserted"&gt;
                                                    &lt;InsertItemTemplate&gt;
                                                        &lt;table&gt;....&lt;/table&gt;
                                                    &lt;/InsertItemTemplate&gt;
                                                &lt;/asp:FormView&gt;
</code></pre>

<p>label works fine in other tabpanel that doesn't contain formview </p>
