  Hi
  
  I have displayed the treeview by overriding the GetEditorControl method in GeneralCellType, but the selected node in treeview cannot be written into the cell, and the page will automatically refresh

  see TreeComboBoxCellType.cs in attachment

  Hi,
  
  We are sorry for the delayed response on this. We need the following correction:
  
  Server side:
  
  Models\TreeComboBoxCellType.cs: Add the CSS class for TreeView and TreeView’s leaf. Sets the node NavigateUrl is “#” to ignore postback.
  
  Client-side:
  
  WebForm1.aspx: Adds the script to handle node click, saves element’s value by selected node’s value and stop editing cell.
  
  TreeComboEditorScript.js/TreeComboRenderScript.js: Uncomment the test logic to get/set the actual editor’s value.

  Please refer to the attached sample for reference.
