Hi maniks,

I have changed your code and wroking correctly with no error. Check the below code.

HTML

<div>
    <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" Font-Names="Arial"
        Font-Size="11pt" AlternatingRowStyle-BackColor="#C2D69B" HeaderStyle-BackColor="green"
        AllowPaging="false">
        <Columns>
            <asp:BoundField ItemStyle-Width="50px" DataField="ENO" HeaderText="ENO" />
            <asp:BoundField ItemStyle-Width="150px" DataField="ENAME" HeaderText="ENAME" />
            <asp:BoundField ItemStyle-Width="150px" DataField="JOB" HeaderText="JOB" />
        </Columns>
    </asp:GridView>
</div>
<br />
<asp:Button ID="btnPrint" runat="server" Text="Print" OnClick="Gridprint" />

Code
