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.

You should probably take a look at the 'UltraTree PropertyGrid' sample that ships with the product; the sample was written before the ability to edit cells was added, but to enable cell editing you can set the ColumnSettings.AllowCellEdit property (you might also want to set Override.CellClickAction if you want cells to enter edit mode on a MouseDown).

Regarding the exception you were getting when embedding the UltraNumericEditor: that control only supports the Integer and Double data types, so you can't embed that editor in a column of some other data type.

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.
