Editors
LookUp Editors - AutoSuggest mode (virtual search)
WinForms LookUpEdit and GridLookUpEdits controls support new user-friendly search options.
在AutoSuggest模式下，只要用户在其中输入文本，WinForms Lookup editor就会触发一个AutoSuggest事件。 您可以处理此事件并将异步任务分配给QuerySuggestions参数来填充查找列表，此异步任务应检查在查找中输入的文本，并为编辑器的下拉窗口返回一个项目集合。
lookUpEdit1.AutoSuggest += OnAutoSuggest;
// ...
// Setup(LookUp edit):
lookUpEdit1.Properties.SearchMode = SearchMode.AutoSuggest;
void OnAutoSuggest(object sender, LookUpEditAutoSuggestEventArgs e) {
e.QuerySuggestions = (Task<ICollection>) ... ;
}
Lookup Editors - AutoSearch模式
AutoSearch模式是为绑定的LookUpEdit和GridLookUpEdit控件设计的，自动搜索 "unlocks"编辑器的文本框，并允许用户在其中输入“搜索”条件。编辑器将隐藏与文本字段中输入的文本不匹配的数据源记录，并在其下拉窗口中显示匹配的条目。
要启用自动搜索模式，请将SearchMode属性设置为'AutoSearch'。
您可以处理自动搜索事件来微调搜索结果和/或自定义文本突出显示逻辑。
// Setup (default behavior)
lookUpEdit1.Properties.SearchMode = SearchMode.AutoSearch;
// Customisation
lookUpEdit1.Properties.SearchMode = SearchMode.AutoSearch;
lookUpEdit1.AutoSearch += OnAutoSearch;
// ...
void OnAutoSearch(object sender, LookUpEditAutoSearchEventArgs e) {
e.SetParameters(...);
}
TimeSpan Edit Mask
The new TimeSpan and TimeSpanAdvancingCaret mask allows end users to enter the interval, two masks supports negative interval.
