nauna says:

 <div class="input-group">

  <asp:TextBox ID="TextBox1" runat="server" placeholder="Write Comment and Make Point" BorderStyle="Solid" BorderColor="#CCCCCC" BorderWidth="1px" CssClass="form-control"></asp:TextBox>

      <span class="input-group-btn">

     <asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False" CommandName="comment"  Font-Underline="False" CssClass="btn btn-default"> <i class="fa fa-send"></i> </asp:LinkButton>

      </span>

    </div>

 Replace above code with below.

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
        <div class="input-group">
            <asp:TextBox ID="TextBox1" runat="server" placeholder="Write Comment and Make Point"
                BorderStyle="Solid" BorderColor="#CCCCCC" BorderWidth="1px" CssClass="form-control"></asp:TextBox>
            <span class="input-group-btn">
                <asp:LinkButton ID="LinkButton2" runat="server" Text="Submit" OnClick="OnUpdate"
                    CausesValidation="False" CommandName="comment" Font-Underline="False" CssClass="btn btn-default"> <i class="fa fa-send"></i> </asp:LinkButton>
            </span>
        </div>
    </ContentTemplate>
</asp:UpdatePanel>
