更改默认选择的筛选操作符
要更改默认选择的筛选操作符，必须处理FilterOperatorsLoadingRadGridView的事件，并在事件参数中设置它们。当FilteringMode是FilterRow，则只需要设置第一个操作符。
private void onradgridviewfilteroperatorloadading(对象发送者，telererik . windows . controls . gridview . filteroperatorsloadingeventargs e) {if (e.列。UniqueName == "HireDate") {e.DefaultOperator1 = Telerik.Windows.Data.FilterOperator.IsGreaterThan;e.DefaultOperator2 = Telerik.Windows.Data.FilterOperator.IsLessThan;}}Private Sub OnRadGridViewFilterOperatorsLoading(sender As Object, e As Telerik.Windows.Controls.GridView.FilterOperatorsLoadingEventArgs)如果e.c oln . uniquename = "HireDate"那么e.f ertoperator1 = telerik . windows . data . filteroperatorisgreaterthan e. defaultoperator2 = telerik . windows . data . filteroperatorisessthan结束如果结束Sub . islessthan请注意，您不能对可用的操作符重新排序。
