DevExpress TreeList 调优_绑定数据源方式, 放弃原来的AppendNode加载数据的方式

注意事项1： 由于一旦绑定了数据源dataTable的些许变化便在TreeList中有所体现, 所以等dataTable完全填充好了之后再绑定数据源.

 

 注意事项2：dataTable每行的父节点ID当加载到目前为止,还没有找到那么可能就当成空了, 所以最后treelist呈现就有问题, 所以解决办法有3个, 1： 大范围数据,也就是父节点的数据一定要先于子节点在表中排列.(这个不好控制).  2： 等完全填充完datatable时再重新设置每行的父节点ID.   
 3：可以边填充边设置, 最后再绑定数据源, 在填充dataTable之前先解绑数据源, 即先把数据源设为空,完全填充好再重新绑定(经过测试这种方法的加载速度最快了)
 

 参看代码如下:

 

  public void ShowData(ForecastService.TrafficResult[] result, int iscrop, bool AllType)
 
 
 

          {
 
 
 

  
 
 

              //填充数据
 
 
 

              try
 
 
 

              {
 
 
 

                  ResetCtrl(AllType);
 
 
 

                  this.result = result;
 
 
 

                  treeListResult.Nodes.Clear();
 
 
 

                  
  treeListResult.DataSource = null; //一定要先解绑
 
 
 

                  
 
 
 

                  FillTypeFirstData(result, this.dtResult);
 
 
 

                  
  treeListResult.DataSource = dtResult;
 
 
 

  
 
 

                  if (treeListResult.Nodes.Count > 0)
 
 
 

                  {
 
 
 

                      for (int i = 0; i < treeListResult.Nodes.Count; i++)
 
 
 

                      {
 
 
 

                          treeListResult.Nodes[i].HasChildren = true;
 
 
 

                          treeListResult.Nodes[i].Expanded = true;
 
 
 

                      }
 
 
 

                  }
 
 
 

              }
 
 
 

              catch (Exception ex)
