问题:
需要动态为WPF中的DataGrid添加列,并动态绑定相应数据.(此处仅实现动态属性的添加和使⽤,关于动态⽅法的添加和使⽤详见推荐阅读)实现关键点:
⽬标类继承DynamicObject,添加动态属性集合,并重写⽅法TrySetMember()和TryGetMember()
public void BtnQuery() {
var view = this.GetView() as MainScreenView; if (view != null) {
view.dgdNurseScheduleStatistics.Columns.Clear();
var scheduleClassList = Connectors.NurseScheduleStatisticsConnector.GetInstance.FindScheduleClassList().OrderBy(item => item.Id); if (scheduleClassList != null) {
List dynamic model = new NurseScheduleStatisticsModel(); model.col0 = i; model.col1 = i; model.col2 = i; model.col3 = i; model.col4 = i; modelList.Add(model); } for (int i = 0; i < 5; i++) { DataGridTextColumn column = new DataGridTextColumn(); column.Header = \"col\" + i; column.Binding = new Binding(\"col\" + i); view.dgdNurseScheduleStatistics.Columns.Add(column); } view.dgdNurseScheduleStatistics.ItemsSource = modelList; } } } public class NurseScheduleStatisticsModel : DynamicObject { public string EmpName { get; set; } public string TotalHour { get; set; } public string TotalWork { get; set; } Dictionary if (!Properties.Keys.Contains(binder.Name)) { //在此可以做⼀些⼩动作 //if (binder.Name == \"Col\") // Properties.Add(binder.Name + (Properties.Count), value.ToString()); //else // Properties.Add(binder.Name, value.ToString()); Properties.Add(binder.Name, value.ToString()); } return true; } public override bool TryGetMember(GetMemberBinder binder, out object result) { return Properties.TryGetValue(binder.Name, out result); } } 效果图: 推荐阅读: 原⽂地址: 因篇幅问题不能全部显示,请点此查看更多更全内容
