Changing default group operator

[Mark DeMichele]

Hi,

With regards to the RadFilter, how would one change the default group operator whenever a group is created? Specifically, I'd like each group to default to OR instead of AND.

Hello Mark,

Please use the following code in order to implement the desired functionality:

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        RadFilter1.RootGroup.GroupOperation = RadFilterGroupOperation.Or;
    }
}

protected void RadFilter1_ItemCommand(object sender, RadFilterCommandEventArgs e)
{
    if (e.CommandName == RadFilter.AddGroupCommandName)
    {
        e.Canceled = true;
        RadFilterGroupExpression group1 = new RadFilterGroupExpression();
        group1.GroupOperation = RadFilterGroupOperation.Or;
        (e.ExpressionItem as Telerik.Web.UI.RadFilterGroupExpressionItem).Expression.AddExpression(group1);
        RadFilter1.RecreateControl();
    }
}

I hope it helps.

Best wishes,
