Hi
i have datatable with some columns and rows..
and i fill listview from datatable in DataPager1_PreRender...

Also i have checkboxlist OnSelectedIndexChanged , i want to filter from datatable and fill listview according to checkbox selected

When i do this, the page reloads and shows results..what i want is only listview (that much div part) should be reload/refresh and page should remain at same position...

I used <updatepanel>,maintainpagescrollposition true , but still it page reloads ...

The code in aspx is ........

<updatepanel>
<contenttemplate>
<asp:CheckBoxList ID="chkCountries" runat="server" AutoPostBack="true" OnSelectedIndexChanged="Country_Selected">
<asp:ListItem Text="rating 5" Value="5">
<asp:ListItem Text="rating 4" Value="4">
<asp:ListItem Text="rating 3" Value="3">
<asp:ListItem Text="rating 2" Value="2">

<asp:ListView ID="ProductListList" runat="server" >
<layouttemplate>
<blockquote>
<asp:PlaceHolder runat="server" ID="itemPlaceholder">
</blockquote>

<itemtemplate>
<%#Eval("Hoteldescp") %>

The code in aspx.cs is

protected void Page_Load(object sender, EventArgs e)
{
ProductListList.Page.MaintainScrollPositionOnPostBack = true;
DataTable table_temp = (DataTable)Session["SearchHotel"];
ProductListList.DataSource = table_temp;
}

protected void DataPager1_PreRender(object sender, EventArgs e)
{
}

}

protected void Country_Selected(object sender, EventArgs e)
{

filter.Append(" tester = '" + Cntyitem.Value + "'");
dv.RowFilter = filter.ToString();

table_temp_f = dv.ToTable();

ProductListList.DataSource = table_temp_f;

}

Hi,

C#

protected void Page_Load(object sender, EventArgs e)
{

if(!Page.IsPostBack)
{      
  ProductListList.Page.MaintainScrollPositionOnPostBack = true;
DataTable table_temp = (DataTable)Session["SearchHotel"];
 ProductListList.DataSource = table_temp;
}
}

Add in Page load like above.

User AJAX Update Panel for you ListView for partial reload.
