custom filter not working

[Aaron]

I'm getting this error "No property or field 'PhoneNumber' exists in type 'DataRowView'" when I try to rebind my grid after changing the filterexpression.
I hope someone can explain why.
My c# code is:

protected void btnFilter_Click(object sender, EventArgs e)
        {
            string filter = "";

            switch (cboFilter.SelectedValue)
            {
                case "AccountNumber":
                    {
                        filter = String.Format("(AccountNumber LIKE '%{0}%')", txtFilter.Text.Trim());
                        break;
                    }
                case "DateRange":
                    {
                        if ((rdpDateFrom.SelectedDate != null) && (rdpDateTo.SelectedDate != null))
                        {
                            filter = String.Format("(DateFrom >= {0}) AND (DateTo <= {1})", rdpDateFrom.SelectedDate, rdpDateTo.SelectedDate);
                        }
                        else if ((rdpDateFrom.SelectedDate != null) && (rdpDateTo.SelectedDate == null))
                        {
                            filter = String.Format("(DateFrom >= {0})", rdpDateFrom.SelectedDate);
                        }
                        else if ((rdpDateFrom.SelectedDate == null) && (rdpDateTo.SelectedDate != null))
                        {
                            filter = String.Format("(DateTo <= {0})", rdpDateTo.SelectedDate);
                        }
                        break;
                    }
                case "FullName":
                    {
                        filter = String.Format("(FullName LIKE '%{0}%')", txtFilter.Text.Trim());
                        break;
                    }
                case "PhoneNumber":
                    {
                        filter = String.Format("(PhoneNumber LIKE '%{0}%')", txtFilter.Text.Trim());
                        break;
                    }
            }
            rgBills.MasterTableView.FilterExpression = filter;
            rgBills.MasterTableView.DataBind();
        }

Hello Aaron,

Can you tell us what DataSourceControl you are using to populate RadGrid?
You can try calling rgBills.Rebind() instead of calling DataBind method on Button.Click. Please give this suggestion a try.
