focus a div on link button click - asp.net

Question

In my page, I have a gridview with link buttons in a column.
By clicking the link button should show a div below the gridview.
I gave href in onClientClick event of the link button as follows.
function showDiv() {
location.href = '#div1';
}
When I click the link button the div is showing, but after the page load the page goes up.
aspx code
<asp:GridView ID="gridDate" runat="server" CssClass="gridview_Order"
HeaderStyle-BackColor="#09182F" HeaderStyle-ForeColor="#ffffff"
AutoGenerateColumns="false" Visible="False">
<Columns>
<asp:TemplateField ItemStyle-Width="20%" HeaderText="Sl No." ItemStyle-CssClass="paddng">
<ItemTemplate>
<%#Container.DataItemIndex+1 %>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField ItemStyle-Width="25%" HeaderText="DATE" ItemStyle-CssClass="paddng">
<ItemTemplate>
<asp:LinkButton ID="lbtnDate" runat="server" CommandArgument='<%#Eval("tblName") %>' Text='<%# Eval("dtvar") %>' OnClientClick="showDiv()" OnCommand="lbtnDate_Click"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField ItemStyle-Width="25%" HeaderText="" ItemStyle-CssClass="paddng">
<ItemTemplate>
<asp:LinkButton ID="lbtnDownload" runat="server" Text="Download Excel" CommandArgument='<%# Eval("tblName") %>' OnCommand="lbtnDownload_Click"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<br /><hr /><br />
<div id="div1">
<asp:GridView ID="gridOrderByUser" runat="server" CssClass="gridview"
HeaderStyle-BackColor="#09182F" HeaderStyle-ForeColor="#ffffff"
AutoGenerateColumns="false" Visible="False" >
<Columns>
<asp:TemplateField ItemStyle-Width="2%" HeaderText="Sl No.">
<ItemTemplate>
<asp:Label ID="lblSlNo1" runat="server" Text='<%#Container.DataItemIndex+1 %>' style="color:#000;"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="cod" HeaderText="CODE" InsertVisible="False" ReadOnly="True" SortExpression="cod" ItemStyle-Width="16%" />
<asp:TemplateField HeaderText="IMAGE" ItemStyle-Width="18%">
<ItemTemplate>
<asp:Image ID="img1" runat="server" Height="100px" Width="54px" ImageUrl='<%#"~/images/"+Eval("Image") %>' />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</div>
So what should I do for staying the page in the div position.
Thanks

If you dont need the server side event of the link button you could do this:
OnClientClick="location.href = '#div1'; return false;"
