    AutoLoadParams not applied with RemoteFilter

    Hi,
    I found out, that Ext.Net.Store.AutoLoadParams is not applied to first request of store, if Ext.Net.Store.RemoteFilter is true and there are som GridFilters in grid connected with store.

    Example:

    <%@ Page Language="C#" AutoEventWireup="true" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <ext:ResourceManager runat="server" />
    <ext:Store
        ID="store"
        runat="server"
        AutoLoad="true"
        RemoteFilter="true"
        OnReadData="storeMain_RefreshData">
        <Proxy>
            <ext:PageProxy />
        </Proxy>
        <Model>
            <ext:Model runat="server" IDProperty="ID">
                <Fields>
                    <ext:ModelField Name="ID"  />
                    <ext:ModelField Name="Name" />
                </Fields>
            </ext:Model>
        </Model>
<%--        <AutoLoadParams>
            <ext:Parameter Name="start" Value="40" />
        </AutoLoadParams>--%>
    </ext:Store>
    <ext:Viewport ID="viewport" runat="server" Layout="border">
        <Items>
            <ext:GridPanel
                ID="gridMain"
                runat="server"
                Region="Center"
                StoreID="store">
                <ColumnModel>
                    <Columns>
                        <ext:Column Width="150" runat="server" DataIndex="Name" Text="Name">
                            <Filter>
                                <ext:StringFilter />
                            </Filter>
                        </ext:Column>
                        <ext:Column Width="140" runat="server" DataIndex="ID" Text="ID" />
                    </Columns>
                </ColumnModel>
                <View>
                    <ext:GridView runat="server" />
                </View>
                <Plugins>
                    <ext:GridFilters runat="server" />
                </Plugins>
            </ext:GridPanel>
        </Items>
    </ext:Viewport>
    </form>
</body>
</html>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest) this.store.AutoLoadParams["start"] = "40";
    }
    protected void storeMain_RefreshData(object sender, StoreReadDataEventArgs e)
    {
        if (e.Start == 40)
        {
            // OK
        }
        else
        {
            // WRONG
        }
    }
</script>
    Is it a bug or intended behavior?

    Thanks.

    There are some more issues:

    1) Paging toolbar does not change its page according to store's start parameter (I believe it worked in Ext.NET 1.6).

    2) If Ext.Net.Store.RemoteFilter=true, Ext.Net.Store.AutoLoad is ignored

    Example:
    Try combinations:
    - AutoLoad=true, RemoteFilter=true (wrong data, wrong paging toolbar)
    - AutoLoad=true, RemoteFilter=false (right data, wrong paging toolbar)
    - AutoLoad=false, RemoteFilter=true (loads automatically)
