Thanks. I tried but this exception is raised: "The Owner specified a type to EditorWithMask that is not supported by the editor."

By the way, the code of my previous post implies that a new Tree control is placed on the form with no modifications, and that a NumericEditor is also placed (styled with an Office 2007 look). You can see in the code that a single column and a single node is added.

Any ideas?

Thanks a lot. 

I am still having problems setting the editor. Please, allow me to explain what I intend to do:
  - I want to configure the Tree with 2 columns ("Property" and "Value")
  - Only cells of the second column can be edited
  - Each cell can have a different kind of editor
 
So far, I cannot get the tree to have editable cells.

Any ideas?

Thanks a lot.

The idea is to use Infragistics.Win.UltraWinEditors, but there is a problem when you try to work with masked ones like Date, DateTime, Time, masked currency. masked double and masked integer, for this I use the Infragistics.Win namespace, for the others (Text, Color, Font, Dropdown, CheckBox, Radio button, etc) I use the Infragistics.Win.UltraWinEditors directly.

For more information on cell UltraWinEditors see the frmCellValueList.vb form example in C:\...\Windows Forms\Samples\WinGrid\Vb\SamplesExplorer

So far, the sample code provided by giochi7 (and I am grateful) is the only one that I made it to work. However, in the scenario that I am working in, I need to create the following controls at runtime (in a number and of a type depending of a custom configuration file):

- A datepicker like control
- A combobox
- A textbox
- A numeric control
- A textbox but with a button attached at the right
- A Checkbox
- A radio button

Now, I do not know if i should be using classes within the Infragistics.Win.UltraWinEditors namespace or classes within the Infragistics.Win namespace.

What I do know is that I cannot get the runtime created editors to work. Any suggestions and advice would be very appreciated.

Thanks a lot.

I tried using the Infragistics.Win.DateTimeEditor object instead as follows but when double-clicking the cell editing behaves as if it were a text edit:

         UltraTree1.Nodes(0).SetCellValue(objSecondColumn, Now)
        UltraTree1.Nodes(0).Override.CellClickAction = Infragistics.Win.UltraWinTree.CellClickAction.EditCell
        UltraTree1.Nodes(0).Override.UseEditor = Infragistics.Win.DefaultableBoolean.True       
        UltraTree1.Nodes(0).Override.SelectionType = Infragistics.Win.UltraWinTree.SelectType.Single
        UltraTree1.Nodes(0).Override.ShowEditorButtons = Infragistics.Win.UltraWinTree.ShowEditorButtons.Always
        UltraTree1.Nodes(0).Override.Editor = New Infragistics.Win.DateTimeEditor ' <----

The following line displays "EditorWithText" instead of "DateTimeEditor":

MsgBox(TypeName(UltraTree1.Nodes(0).Cells(objSecondColumn).EditorResolved).ToString)

There is a little tricky solution, but I hope that exist another form to do it. Following your code, place a UltraDateTimeEditor1 in the Form1

In the Form1_Load event
      Dim objFirstColumn As Infragistics.Win.UltraWinTree.UltraTreeNodeColumn
      Dim objSecondColumn As Infragistics.Win.UltraWinTree.UltraTreeNodeColumn

      UltraTree1.ViewStyle = Infragistics.Win.UltraWinTree.ViewStyle.OutlookExpress
      UltraTree1.Override.UseEditor = Infragistics.Win.DefaultableBoolean.True
      UltraTree1.Override.LabelEdit = Infragistics.Win.DefaultableBoolean.True
      UltraTree1.Override.CellClickAction = Infragistics.Win.UltraWinTree.CellClickAction.EditCell

      objFirstColumn = UltraTree1.ColumnSettings.RootColumnSet.Columns.Add("Col1")
      objSecondColumn = UltraTree1.ColumnSettings.RootColumnSet.Columns.Add("Col2")

      UltraTree1.Nodes.Add("TestNode")
      UltraTree1.Nodes(0).SetCellValue(objFirstColumn, "Value11")
      UltraTree1.Nodes(0).SetCellValue(objSecondColumn, "Value12")

      'The Dock property must be Fill ***********
      UltraTree1.Dock = DockStyle.Fill

      objSecondColumn.AllowCellEdit = Infragistics.Win.UltraWinTree.AllowCellEdit.Full
      With UltraTree1.Nodes(0)
         .Override.CellClickAction = Infragistics.Win.UltraWinTree.CellClickAction.EditCell
         .Override.UseEditor = Infragistics.Win.DefaultableBoolean.True
         .Override.SelectionType = Infragistics.Win.UltraWinTree.SelectType.Single
         .Cells(objSecondColumn).EditorControl = UltraDateTimeEditor1
         .SetCellValue(objSecondColumn, Now)
      End With

      With UltraDateTimeEditor1
         .Visible = False
         .AllowDrop = True
         .AutoSize = True
      End With

      Me.UltraTree1.ColumnSettings.BorderStyleCell = Infragistics.Win.UIElementBorderStyle.Solid
      Me.UltraTree1.ColumnSettings.CellAppearance.BorderColor = SystemColors.Control

In the UltraTree1 BeforeCellActivate
      If TypeOf e.Cell.EditorControl Is Infragistics.Win.UltraWinEditors.UltraDateTimeEditor Then
         With UltraDateTimeEditor1
            .Height = e.Cell.UIElement.Rect.Height
            .Width = e.Cell.UIElement.Rect.Width
            .Top = e.Cell.UIElement.Rect.Location.Y
            .Left = e.Cell.UIElement.Rect.Location.X
            .Enabled = True
            .Visible = True
         End With
      Else
         UltraDateTimeEditor1.Enabled = False
         UltraDateTimeEditor1.Visible = False
      End If

In the UltraTree1 BeforeCellDeactivate
      If TypeOf e.Cell.EditorControl Is Infragistics.Win.UltraWinEditors.UltraDateTimeEditor Then
         e.Cell.Value = UltraDateTimeEditor1.Value
         UltraDateTimeEditor1.Enabled = False
         UltraDateTimeEditor1.Visible = False
      End If

Your are right: I can't have the DateTimeEditor to work, yet. I am quite frustrated.
