  PROJECT DESCRIPTION
  This project shows how to Drag and Drop Items from RadGrid to RadTreeView and vice-versa.
  
  Drag and Drop in RadGrid -> RadTreeView direction is handled by custom JavaScript logic.
  
  Drag and Drop in RadTreeView -> RadGrid direction is handled by using the built-in Drag and Drop functionality of the RadTreeView.
  
  The project also shows a sample approach to the case when RadTreeView and RadGrid are in MasterPage and ContentPage respectively.

  Can this be enhanced to support two-way drag and drop support? In other words, drag from a TreeView on to a RadGrid? That would obviously be harder since the Grid may have to load data based on the key to completely fill the row, but it's conceivable that a scenario with drag-and-drop would want two-way support.
  
  Very cool demo, though! Great work.

  Hi Todd Anglin,
  
  I agree that it would be better if the Drag And Drop can happen in both directions (RadGrid<->RadTreeView). I will try to update the project as soon as possible.
  
  Kind regards,

  I'm looking at that example since yesterday evening, still trying to find out what the relevant parts of it are. Some documentation would have been really nice. Also the code is horribly formatted and absolutely not commented.
  
  The next thing is, that I first have to upgrade my current project to this new Version, which doesnt seem to be quite easy, since the whole structure changed. Another ordeal with telerik controls.

  Nick-
  
  Any update on the progress updating the demo to show the RadTreeview to RadGrid drag-and-drop operation? I've talked to more people recently that would love to see this two-way operation.
  
  Thanks-
  Todd

  Hello there,
  
  @Todd:
      I have updated the project to show both Drag and Drop directions.
  
  @DENIS LABERGE, charles:
      Currently, we are working on a CL which will illustrate dragging and dropping of multiple rows from RadGrid to RadTreeView (using the built-in drag and drop functionality of the RadGrid). Hopefully, the project will be published very soon.
  
  Any comments/feedback are appreciated.

  Hi,
  
  what are the steps to use your sample in the way that treeview is on the masterpage and grid inside a content area?
  
  Thanks!

• Simon Simon

  Posted on Sep 24, 2008 (permalink)

  Hello Christian,
  
  This could be achieved in various ways but the basic idea is the same - the correct RadGrid and the MasterTableView IDs should be available on the client. I have modified the sample project to illustrate one possible implementation.
  
  Please download it and see it for the details.

  Hi
  
  How do I get the RadAjaxManager1_AjaxRequest Method executed if I have only a AjaxManagerProxy on my Page? There is no property "OnAjaxRequest" on the proxy. I found some kind of solution here: http://www.telerik.com/community/forums/aspnet-ajax/ajax/radajaxmanagerproxy-issue.aspx but I don't get it working for this drag-drop function.
  
  Thanks for help!

  Hey Peter-

  
  

  Assuming your goal is to write some server-side code that handles a Ajax event fired by JavaScript on a ContentPage (with a AjaxManager on your MasterPage, and a AjaxManagerProxy on your content page), you can use this snippet:

  
  

  //In your ContentPage OnPageLoad

  protected void Page_Load(object sender, EventArgs e)

  {

  //Get reference to AjaxManager (from Master)

  var manager = RadAjaxManager.GetCurrent(this);

  //Create a new delegate to handle the AjaxRequest event

  manager.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(YourContentPage_AjaxRequest);

  //Add your ajax settings programmatically (with ref to Master manager)

  manager.AjaxSettings.AddAjaxSetting(manager, this.controlToUpdate);

  }

  //Handle the Ajax event in your ContentPage code behind

  private void YourContentPage_AjaxRequest(object sender, AjaxRequestEventArgs e)

  {

  //Optionally process supplied event arg

  switch (e.Argument)

  {

  case "SomeEventArgument":

  //Do something

  break;

  }

  }

  
  

  This allows you to handle your ajax requests in your content page code when they're fired from the client, like this:

  
  

  function someJavaScriptFunction() {

  //Get reference to RadAjaxManager on page

  if (radManager == null)

  radManager = $find('<%= RadAjaxManager.GetCurrent(this).ClientID %>');

  //Fire ajax request (optionally pass an event arg value)

  radManager.ajaxRequest("SomeEventArgValue");

  }

  
  

  Hope that helps!

  -Todd

  I am working with latest trial download of ASP.Net controls. I need functionality to drag and drop from radgrid to radtreeview control. I downloaded this solution from the forum but am getting this error:
  Unable to cast object of type Telerik.web.ui.radgrid to Telerik.web.ui.gridtableview
  
  Can you please help with that?
  Thanks,
