  Hi,
  In codebehind I can select a RadTreeNode like this:
  
  

  //SPTree.Nodes

  RadTreeNode rtn2 = SPTree2.FindNodeByText(dr["sStoredProcedureName"].ToString());

  if (rtn2 != null)

  {

  rtn2.Selected = true; // select it.

  }
  
  However, if there are lots of nodes on this tree then my selected node may not be visible. I need something like a ScrollIntoView method, or similar.
  How to get it to work in codebhind?
  
  Thanks

  Hello Control_Freq,
  
  There is no such method on the server-side. You should use client-side logic to accomplish your task. For example, you can hook on the onload event of the body element and scroll to the selected node. Please check the following help article that shows the needed approach:
  Scrolling To The selected node
  
  Hope this helps.

  Well, I need to do this in response to other events, so the onLoad method doesn't do what I want.
  
  I think I will redesign my webpage so that I don't need this functionality. I have found in the past that if telerik controls don't do what I want, then it is quicker to start again, from the start, than to start banging head against the wall.
  
  Thanks anyway.

  Hi Control_Freq,
  
  There is something else that has just came to my mind. RadTreeView has a RetainScrollPosition property that should retain the scroll position of the selected node. Please make sure that this property is enabled.
  
  All the best,

  Is this property gone?  I Don't see it anymore and it doesn't exist in the class when I try and use it in C#.  I saw a page of docs for it, but when I got to the RadTreeView member variables it doesn't exist.  Is there a new way to handle this?
  
  Thanks!
