UpdatePanel Not works fine

Question

Hi,

 

When I use Button inside Update panel it doesnot fire click event but outside the update panel it works.

 

here is the code

<asp:UpdatePanel ID="updatePanel1" runat="server" UpdateMode="Conditional"
ChildrenAsTriggers="true">
<ContentTemplate>
<asp:Button ID="LinkButton1" runat="server" class="btn btn-primary" Style="color: #fff; background-color: #337ab7; border-color: #2e6da4; display: inline-block; padding: 6px 8px; margin-bottom: 0; border: 1px solid transparent; border-radius: 4px;"
OnClick="LinkButton1_Click" Text='<%#Eval("Row#") %>' />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="LinkButton1" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
