Here is the sample of how I do filtering. When data is filtered and then a cell is edited, the grid is refreshed and filter is removed.
All the records without filter is loaded.

<%@ Import Namespace="System.Collections.Generic" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<script runat="server">
public class Company
{
public int ID { get; set; }
public string Name { get; set; }
public double Price { get; set; }
}
protected void Page_Load(object sender, EventArgs e)
{
if (!X.IsAjaxRequest)
{
this.BindData();
}
}
private void BindData()
{
Store store = this.GridPanel1.GetStore();
store.DataSource = this.GetData();
store.DataBind();
}
private List<Company> GetData()
{
DateTime today = DateTime.Today;
return new List<Company>
{
new Company { ID = 1, Name = "3m Co", Price = 71.72 },
new Company { ID = 2, Name = "Alcoa Inc", Price = 29.01},
new Company { ID = 3, Name = "Altria Group Inc", Price = 83.81},
new Company { ID = 4, Name = "American Express Company", Price = 52.55},
new Company { ID = 5, Name = "American International Group, Inc.", Price = 64.13},
new Company { ID = 6, Name = "AT&T Inc.", Price = 31.61},
new Company { ID = 7, Name = "Boeing Co.", Price = 75.43},
};
}
[DirectMethod(Namespace = "CompanyX")]
public void Edit(int id, string field, string oldValue, string newValue, object customer)
