manual filter no longer works

[Elliott]

the following code worked fine in 2010 version but throws exceptions in 2011.3.3115.35

protected void cmbShipDate_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
{
    string filterExpression;
    filterExpression = RemoveFilter("ShipDate");
    rgEditOrder.MasterTableView.FilterExpression = filterExpression;
    if (cmbShipDate.SelectedItem.Text == "All")
        filterExpression = string.Empty;
    else
        filterExpression = "([ShipDate] = '" + cmbShipDate.SelectedItem.Text + "')";
    rgEditOrder.MasterTableView.FilterExpression = AppendFilterExpression(filterExpression);
    rgEditOrder.EditIndexes.Clear();
    ClearOutItemData();
    rgEditOrder.MasterTableView.Rebind();
}

private string AppendFilterExpression(string filterExpression)
{
    StringBuilder sb;
    sb = new StringBuilder(rgEditOrder.MasterTableView.FilterExpression);
    if (filterExpression == string.Empty)
        return sb.ToString();
    if (sb.ToString() != string.Empty)
    {
        sb.Append(" AND ");
    }
    sb.Append(filterExpression);
    return sb.ToString();
}

what gives?

Hello Marianne,

What exactly is the exception that you get? Have you tried setting the EnableLinqExpressions property of RadGrid to false? If the exception you get is "Expression expected", this setting should fix it.

The thing is that with the .NET 3.5 build of RadGrid for ASP.NET AJAX and LINQ filter expressions enabled (EnableLinqExpressions = true), the filter expressions set for the grid either internally by its filtering mechanism or manually in code should conform to the LINQ expression syntax instead of the old T-SQL syntax. Only thus they will be evaluated properly by the control.

All the best,
