How to traverse each group?

[Vatsal]

Hi,

I am using radfilter control to filter my grid. I want to traverse each group and filter of each group programmatically. Currently I am using "RadFilter1.RootGroup.Expressions" method but it shows only root group and it's filter. How do I traverse other group and it's filter. Please help.

Thanks

Not sure that this is the best or intended way, but seems to be working for me.

protected string TraverseFilterGroups(Telerik.Web.UI.RadFilterGroupExpressionItem groupItem)
{
    string translatedExpression = String.Empty;

    foreach(var child in groupItem.ChildItems)
    {
        if (child is Telerik.Web.UI.RadFilterGroupExpressionItem)
            translatedExpression += " ( " + TraverseFilterGroups((Telerik.Web.UI.RadFilterGroupExpressionItem)child) + ")";
        else
        {
            Telerik.Web.UI.RadFilterSingleExpressionItem expressionItem = (Telerik.Web.UI.RadFilterSingleExpressionItem)child;

            if (expressionItem.Expression.FilterFunction == Telerik.Web.UI.RadFilterFunction.EqualTo)
            {
                translatedExpression += expressionItem.Expression.FieldName + " = " + ((Telerik.Web.UI.RadFilterEqualToFilterExpression<string>)expressionItem.Expression).Value;
            }
        }
        translatedExpression += " " + groupItem.Expression.GroupOperation.ToString() + " ";
    }

    translatedExpression = translatedExpression.Substring(0, translatedExpression.LastIndexOf(' ', translatedExpression.Length-2));
    return translatedExpression;
}
