Recently I faced problem to maintain scroll
position in my page which having A grid with some radio button and check box
with autopostback within a Updatepanel.
The main problem is when a postback occur the page is moving to top. i tried a
lot and finally got the solution.
if you are using IE then its very simple just put the code in your page
directive.
<%@
Page Language="C#"
AutoEventWireup="true"
CodeFile="Default.aspx.cs"
Inherits="_Default"
MaintainScrollPositionOnPostback="true"
%>
but it will not work in Firefox for that you have
to add one browser file into your website
Right click on solution explorer > Add New Item
Select Browser File and add it to App_Browsers folder.
Add MaintainScrollPositionOnPostback capability to this browser file as
written below.
<browsers>
<browser
refID="Mozilla">
<capabilities>
<capability
name="supportsMaintainScrollPositionOnPostback"
value="true"
/>
</capabilities>
</browser>
</browsers>
Some times this also not work,
Then a simple solution just add a blank Update panel after the grid and
onpostback just put the focus to that update panel
it will work in any browser.
<asp:UpdatePanel
ID="UpdatePanel1"
runat="server">
</asp:UpdatePanel>
in cs postbackevent
updatepanel1.Focus();
If any problem just feel free to ask or any
modification reply.
