Hi all,
Solved it by myself using UpdatePanelAnimationExtender.
Just wanted to share if others are looking for same.
Below is the code that is self explanatory.
<pre lang="xml"><asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Label ID="lbl_msg" runat="server" ForeColor="Red" Visible="False"></asp:Label>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btn_save" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
<pre lang="xml"><asp:UpdatePanelAnimationExtender ID="UpdatePanelAnimationExtender1" runat="server"
TargetControlID="UpdatePanel1">
<Animations>
<OnUpdated>
<FadeOut Duration="5.0" Fps="24" />
</OnUpdated>
</Animations>
</asp:UpdatePanelAnimationExtender>
The above fades lbl_msg in 5 sec.
Thanks
