 <telerik:RadGrid ID="radAccountSearch" runat="server" AllowFilteringByColumn="true" ShowGroupPanel="true" GridLines="None"
                AllowPaging="true" AllowSorting="true" OnPreRender="radAccountSearch_PreRender"
                PageSize="9" DataSourceID="ldSource" Skin="Vista" AllowCustomPaging="true">
                <PagerStyle Mode="NextPrevAndNumeric" />
                <MasterTableView TableLayout="Fixed">
                        <%# (((GridItem)Container).ItemIndex != 0)? "</td></tr></table>" : "" %>
                        <asp:Panel ID="ItemContainer" CssClass='<%# (((GridItem)Container).ItemType == GridItemType.Item)? "item" : "alternatingItem" %>'
                            <b>ID : </b>
                            <%# Eval("ID")%>
                            <b>Name : </b>
                            <%# Eval("Name")%>
                            <br />

                <HeaderStyle Font-Bold="false" />
            <asp:LinqDataSource ID="ldSource" runat="server" ContextTypeName="Account.AssetDataContext"
                TableName="AccountContacts" OnSelecting="dsContact_Selecting">

protected void radAccountSearch_PreRender(object sender, EventArgs e)
        int itemCount = (sender as RadGrid).MasterTableView.GetItems(GridItemType.Item).Length + (sender as RadGrid).MasterTableView.GetItems(GridItemType.AlternatingItem).Length;
        foreach (GridItem item in (sender as RadGrid).Items)
            if (item is GridDataItem && item.ItemIndex < itemCount - 1)
                ((item as GridDataItem)["ID"] as TableCell).Controls.Add(new LiteralControl("<table style='display:none;'><tr><td>"));

Hi Selvamanikandan,

If you clear your browser cache this is an expected behaviour. However you could save the RadGrid settings by using GridSettingsPersister. That way you will be able to retrieve you filter values. For more information about GridSettingsPersister I suggest you take a look at the following help topic and this demo which demonstrates its usage.
In case this suggestion does not help I would suggest you to share the whole page markup as well as the related code behind so we could further investigate the issue and do our best to provide a proper solution.

All the best,
